The U.S. has an important choice to make regarding agriculture.

It can import more people to pick crops and do other kinds of agricultural labor, it can raise wages enough to lure more U.S. citizens and immigrants with legal status to take these jobs, or it can import more food. All three options contradict key Trump administration priorities: reducing immigration, keeping prices low and importing fewer goods and services.

The big tax-and-spending bill President Donald Trump signed into law on July 4, 2025, included US$170 billion to fund the detention and deportation of those living in the U.S. without authorization. And about 1 million of them work in agriculture, accounting for more than 40% of all farmworkers.

As the detention and deportation of undocumented immigrants ramps up, one emerging solution is to replace at least some deported farmworkers with foreigners who are given special visas that allow them to help with the harvest but require them to go home after their visas expire.

Such “guest worker” programs have existed for decades, leading to today’s H-2A visa program. As of 2023, more than 310,000 foreigners, around 13% of the nation’s 2.4 million farmworkers, were employed through this program. About 90% of the foreign workers with these visas come from Mexico, and nearly all are men. The states where the largest numbers of them go are California, Florida, Georgia and Washington.

As a professor of Latin American politics and U.S.-Latin American relations, I teach my students to consider the difficult trade-offs that governments face. If the Trump administration removes a significant share of the immigrants living in the U.S. without legal permission from the agricultural labor force to try to meet its deportation goals, farm owners will have few options.

Few options available

First, farm owners could raise wages and improve working conditions enough to attract U.S. citizens and immigrants who are legal permanent residents or otherwise in the U.S. with legal status.

But many agricultural employers say they can’t find enough people to hire who can legally work – at least without higher wages and much-improved job requirements. Without any undocumented immigrant farmworkers, the prices of U.S.-sourced crops and other agricultural products would spike, creating an incentive for more food to be imported.

Second, farm owners could employ fewer people. That would require either growing different crops that require less labor or becoming more reliant on machinery to plant and harvest. But that would mean the U.S. could have to import more food. And automation for some crops is very expensive. For others, such as for berries, it’s currently impossible.

It’s also possible that some farm owners could put their land to other uses, ceasing production, but that would also necessitate more imported food.

Trump administration’s suggested fixes

U.S. Agriculture Secretary Brooke Rollins has predicted that farm owners will soon find plenty of U.S. citizens to employ.

She declared on July 8 that the new Medicaid work requirements included in the same legislative package as the immigration enforcement funds would encourage huge numbers of U.S. citizens to start working in the fields instead of losing their health insurance through that government program.

Farm trade groups say this scenario is far-fetched.

For one thing, most adults enrolled in the Medicaid program who can work already do. Many others are unable to do so due to disabilities or caregiving obligations.

Few people enrolled in Medicaid live close enough to a farm to work at one, and even those who do aren’t capable of doing farmwork. When farm owners tried putting people enrolled in a welfare program to work in the fields in the 1990s, it failed. Another experiment in the 1960s, which deployed teenagers, didn’t pan out either because the teens found the work too hard.

It seems more likely that farm owners will try to hire many more foreign farmworkers to do temporary but legal jobs through the H-2A program.

Although he has not made it an official policy, Trump seems to be moving toward this same conclusion.

In June, for example, Trump said his administration was working on “some kind of a temporary pass” for immigrants lacking authorization to be in the U.S. who are working on farms and in hotels.

Established in 1952, numbers now rising quickly

The guest worker system, established in 1952 and revised significantly in 1986, has become a mainstay of U.S. agriculture because it offers important benefits to both the farm owners who need workers and the foreign workers they hire.

There is no cap on the number of potential workers. The number of H-2A visas issued is based only on how many employers request them. Farm owners may apply for visas after verifying that they are unable to locate enough workers who are U.S. citizens or present in the U.S. with authorization.

To protect U.S. workers, the government mandates that H-2A workers earn an “adverse effect wage rate.” The Labor Department sets that hourly wage, which ranges from $10.36 in Puerto Rico to about $15 in several southern states, to more than $20 in California, Alaska and Hawaii. These wages are set at relatively high levels to avoid putting downward pressure on what other U.S. workers are paid for the same jobs.

After certification, farm owners recruit workers in a foreign country who are offered a contract that includes transportation from their home country and a trip back – assuming they complete the contract.

The program provides farm owners with a short-term labor force. It guarantees the foreign workers who obtain H-2A visas relatively high wages, as well as housing in the U.S. That combination has proven increasingly popular in recent years: The annual number of H-2A visas rose to 310,700 in 2023, a more than fivefold increase since 2010.

Possible downsides

Boosting the number of agricultural guest workers would help fill some gaps in the agricultural labor force and reduce the risk of crops going unharvested. But it seems clear to me that a sudden change would pose risks for workers and farm owners alike.

Workers would be at risk because oversight of the H-2A program has historically been weak. Despite that lax track record, some unscrupulous farmers have been fined or barred from participating in the H-2A program because of unpaid wages and other abuses.

Relying even more on guest farmworkers than the U.S. does today would also swap workers who have built lives and families north of the border with people who are in the U.S. on a temporary basis. Immigration opponents are unlikely to object to this trade-off, but to immigrant rights groups, this arrangement would be cruel and unfair to workers with years of service behind them.

What’s more, the workers with guest visas can be at risk of exploitation and abuse. In 2022, the U.S. attorney for the Southern District of Georgia described conditions for H-2A workers at an onion farm the government had investigated as “modern-day slavery.”

The U.S. Government Accountability Office has researched the H-2A visa program and observed many problems it recommends be fixed.

For farm owners, the downside of ramping up guest worker programs is that it could increase costs and make production less efficient and more costly. That’s because transporting Mexican farmworkers back and forth each year is complicated and expensive. Farm groups say that compliance with H-2A visa requirements is cumbersome. It can be particularly difficult for small farms to participate in this program.

Some farm owners have objected to the costs of employing H-2A workers. Rollins has said that the Trump administration believes that the mandatory wages are too high.

To be sure, these problems aren’t limited to agriculture. Hotels, restaurants and other hospitality businesses, which rely heavily on undocumented workers, can also temporarily employ some foreigners through the H-2B visa program – which is smaller than the H-2A program, limits the number of visas issued and is available only for jobs considered seasonal.

Home health care providers and many other kinds of employers who rely on people who can’t legally work for them could also struggle. But so far, there is no temporary visa program available to help them fill those gaps.

If the U.S. does deport millions of workers, the price of tomatoes, elder care, restaurant meals and roof repairs would probably rise substantially. A vast increase in the number of guest workers is a potential but partial solution, but it would multiply problems that are inherent in these temporary visa programs.

What began as songs about heartbreak in the brothels and barrios of the Dominican Republic in the 1960s has become a worldwide sensation.

Even the Bee Gees have gotten a bachata spin. Prince Royce’s bilingual take on the 1977 hit “How Deep Is Your Love” has topped the Latin music charts this summer and proves bachata is no longer chasing the mainstream but reimagining the pop canon.

Bachata dance classes, parties and festivals have sprung up across the U.S. in recent years, everywhere from Philadelphia to Los Angeles, and Omaha, Nebraska, to Oklahoma City.

It’s easy to find abroad as well. Upcoming bachata festivals are happening in cities in Austria, Egypt, Australia and China.

I’m a scholar of Dominican culture and the senior researcher for the History of Dominican Music in the U.S. project at the City University of New York’s Dominican Studies Institute. I see bachata as a revealing window into modern post-1960s Dominican history – and one that spotlights the emotional truths and everyday experiences of poor and Black Dominicans in particular.

Music from the margins

Bachata was born in the Dominican countryside and later developed in the shantytowns of Santo Domingo, the capital. In most Latin American dictionaries, the word “bachata” is loosely defined as “revelry” or “a spree.”

The distinctive sound is formed from guitars, bongos, bass and the güira – a percussion instrument also used in merengue music – and accompanied by typically romantic or bittersweet lyrics.

The music was long associated with the lower classes and Black Dominicans.

The genre’s first recording came in 1962, just over a year after Rafael Leónidas Trujillo, a brutal dictator who ruled the island for 31 years, was assassinated. Trujillo’s death marked the beginning of a new cultural and political era in the Dominican Republic, although democratic hopes were soon shattered by a military coup, civil war and a second U.S. intervention following an earlier one between 1916-1924.

Urban and middle-class Dominicans looked down on bachata as the music played in brothels and favored by poor, rural people who started to migrate to urban areas in large numbers in the 1960s. It was played almost exclusively on Radio Guarachita, a Santo Domingo station run by Radhamés Aracena, a key promoter of the genre.

Amid a country reeling from political upheaval, bachata emerged as a soundtrack to working-class survival. The guitar-based rhythms were shaped by Cuban bolero and son and Mexican ranchera music, while the lyrics chronicled daily struggles, grief and marginalization.

Bachata’s shifting language

In the 1960s, bachata lyrics centered on heartache and were often directed at a romantic partner.

“Understand me, you know I love only you. Don’t deny me the hope of kissing you again,” Rafael Encarnación sang in Spanish in his 1964 song “Muero Contigo,” or “I Die With You.”

By the late 1970s and early 1980s, sexual innuendos were common, adding to the genre’s low standing among Dominican elites.

“I gave you everything you ever wanted, but it was all useless because you went looking for another man,” Blas Durán sang in 1985. “I was left like the orange vendor – peeling so someone else could suck the fruit.”

To reclaim respect for bachata, some artists, such as Luis Segura and Leonardo Paniagua, in the mid-1980s began calling their music música de amargue, or “music of romantic bitterness.”

What began as a genre label gradually transformed into a sensibility. “Amargue” came to name a feeling marked by longing, loss and quiet introspection – akin to “feeling the blues” in the U.S.

American blues similarly emerged from the hardships faced by Black Americans in the South and expressed themes of sorrow, resilience and reflection.

By the 1990s, the stigma surrounding bachata began to fade, partly due to the international success of Dominican star Juan Luis Guerra and his album Bachata Rosa. The album sold more than 5 million copies worldwide by 1994, earned Guerra a Grammy Award for best tropical Latin album, and was certified platinum in the U.S.

As acceptance of the genre grew, traditional bachateros in the Dominican Republic continued releasing bachata albums. However, Dominican pop, rock and other artists also began recording bachatas – such as 1990’s “Yo Quiero Andar” by Sonia Silvestre and 1998’s “Bufeo” by Luis “El Terror” Días.

Bachata goes mainstream

Migration to the U.S. is a pivotal chapter in Dominican history after the 1960s. The U.S. Immigration Act of 1965 functioned as a de facto immigration policy and encouraged a large-scale exodus from the Dominican Republic.

By the mid-1990s, a strong and vibrant Dominican diaspora was firmly established in New York City. The Bronx became the birthplace of Grupo Aventura, a group that revolutionized bachata by blending its traditional rhythms with urban genres such as hip-hop.

“Obsesión,” released in 2002, was an international hit.

Their music reflected the bicultural diaspora, often torn between nostalgia for their homeland and everyday challenges of urban American life. Against the backdrop of city life, bachata found a new voice that mirrored the immigrant experience. The genre shifted from a shared feeling of loss and longing to a celebration of cultural community.

In 2002, the song “Obsesión” by Aventura and featuring Judy Santos topped music charts in France, Germany, Italy, the U.S. and elsewhere. The group Aventura and, later, lead singer Romeo Santos as a solo artist sold out Madison Square Garden and Yankee Stadium, respectively.

As they rose in fame, Aventura became global ambassadors for Dominican culture and made bachata mainstream.

Global spin on bachata

Bachata’s popularity has also spread to other countries in Latin America, and especially among working-class and Afro-descendant communities in Central America that see their own realities reflected in the music.

At the same time, Dominican diasporic communities in countries such as Spain and Italy carried the genre with them, where it continued to evolve.

In Spain, for example, bachata experienced a creative transformation. By the mid-2000s, bachata sensual had emerged as a dance style influenced by zouk and tango, emphasizing smooth, body-led movements and close partner connection.

Around the same time, modern bachata also developed between Spain and New York City. This style is a departure from traditional bachata, which focuses on the box step and fast footwork, and incorporates more turns and other elements from salsa.

In 2019 bachata was added to UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity, which also lists Jamaican reggae and Mexican mariachi.

Today, bachata’s influence is truly global. International conferences dedicated to the genre attract dancers, musicians and scholars from around the world. Puerto Rican, Colombian and other artists from diverse cultural and racial backgrounds continue to nurture and reinvent bachata.

At the same time, more women, such as Andre Veloz, Judy Santos and Leslie Grace, are building careers as bachata performers and challenging a traditionally male-dominated genre.

Bachata holds a place not only on the world stage but in the hearts of Latino, Black, Asian and many other communities in the U.S. that recognize the genre’s power to tell stories of love, loss, migration and resilience.

The 3 worst things you can say after a pet dies, and what to say instead

Source: The Conversation – USA (3) – By Brian N. Chin, Assistant Professor of Psychology, Trinity College

Loss of a pet falls into what researchers call disenfranchised grief in which the pain is often minimized or discounted. Claudia Luna/iStock via Getty Images Plus

I saw it firsthand after my cat Murphy died earlier this year. She’d been diagnosed with cancer just weeks before.

She was a small gray tabby with delicate paws who, even during chemotherapy, climbed her favorite dresser perch – Mount Murphy – with steady determination.

The day after she died, a colleague said with a shrug: “It’s just part of life.”

That phrase stayed with me – not because it was wrong, but because of how quickly it dismissed something real.

Murphy wasn’t just a cat. She was my eldest daughter – by bond, if not by blood. My shadow.

Why pet grief doesn’t count

More than two-thirds of U.S. households include pets. Americans tend to treat them like family with birthday cakes, shared beds and names on holiday cards.

But when someone grieves them like family, the cultural script flips. Grief gets minimized. Support gets awkward. And when no one acknowledges your loss, it starts to feel like you weren’t even supposed to love them that much in the first place.

I’ve seen this kind of grief up close – in my research and in my own life.
I am a psychologist who studies attachment, loss and the human-animal bond.

And I’ve seen firsthand how often grief following pet loss gets brushed aside – treated as less valid, less serious or less worthy of support than human loss. After a pet dies, people often say the wrong thing – usually trying to help, but often doing the opposite.

When loss is minimized or discounted

Psychologists describe this kind of unacknowledged loss as disenfranchised grief: a form of mourning that isn’t fully recognized by social norms or institutions. It happens after miscarriages, breakups, job loss – and especially after the death of a beloved animal companion.

The pain is real for the person grieving, but what’s missing is the social support to mourn that loss.

Even well-meaning people struggle to respond in ways that feel supportive.
And when grief gets dismissed, it doesn’t just hurt – it makes us question whether we’re even allowed to feel it.

Here are three of the most common responses – and what to do instead:

‘Just a pet’

This is one of the most reflexive responses after a loss like this. It sounds harmless. But under the surface is a cultural belief that grieving an animal is excessive – even unprofessional.

That belief shows up in everything from workplace leave policies to everyday conversations. Even from people trying to be kind.

But pet grief isn’t about the species, it’s about the bond. And for many, that bond is irreplaceable.

Pets often become attachment figures; they’re woven into our routines, our emotional lives and our identities. Recent research shows that the quality of the human-pet bond matters deeply – not just for well-being, but for how we grieve when that connection ends.

What’s lost isn’t “just an animal.” It’s the steady presence who greeted you every morning. The one who sat beside you through deadlines, small triumphs and quiet nights. A companion who made the world feel a little less lonely.

But when the world treats that love like it doesn’t count, the loss can cut even deeper.

It may not come with formal recognition or time off, but it still matters. And love isn’t less real just because it came with fur.

If someone you care about loses a pet, acknowledge the bond. Even a simple “I’m so sorry” can offer real comfort.

‘I know how you feel’

“I know how you feel” sounds empathetic, but it quietly shifts the focus from the griever to the speaker. It rushes in with your story before theirs has even had a chance to land.

That instinct comes from a good place. We want to relate, to reassure, to let someone know they’re not alone. But when it comes to grief, that impulse often backfires. Grief doesn’t need to be matched. It needs to be honored and given time, care and space to unfold, whether the loss is of a person or a pet.

Instead of responding with your own story, try simpler, grounding words:

You don’t need to understand someone’s grief to make space for it. What helps isn’t comparison – it’s presence.

Let them name the loss. Let them remember. Let them say what hurts.

Sometimes, simply staying present – without rushing, problem-solving or shifting the focus away – is the most meaningful thing you can do.

‘You can always get another one’

“You can always get another one” is the kind of thing people offer reflexively when they don’t know what else to say – a clumsy attempt at reassurance.

Underneath is a desire to soothe, to fix, to make the sadness go away. But that instinct can miss the point: The loss isn’t practical – it’s personal. And grief isn’t a problem to be solved.

This type of comment often lands more like customer service than comfort. It treats the relationship as replaceable, as if love were something you can swap out like a broken phone.

But every pet is one of a kind – not just in how they look or sound, but in how they move through your life. The way they wait for you at the door and watch you as you leave. The small rituals that you didn’t know were rituals until they stopped. You build a life around them without realizing it, until they’re no longer in it.

You wouldn’t tell someone to “just have another child” or “just find a new partner.” And yet, people say the equivalent all the time after pet loss.

Rushing to replace the relationship instead of honoring what was lost overlooks what made that bond irreplaceable. Love isn’t interchangeable – and neither are the ones we lose.

So offer care that endures. Grief doesn’t follow a timeline. A check-in weeks or months later, whether it’s a heart emoji, a shared memory or a gentle reminder that they’re not alone, can remind someone that their grief is seen and their love still matters.

When people say nothing

People often don’t know what to say after a pet dies, so they say nothing. But silence doesn’t just bury grief, it isolates it. It tells the griever that their love was excessive, their sadness inconvenient, their loss unworthy of acknowledgment.

And grief that feels invisible can be the hardest kind to carry.

So if someone you love loses a pet, don’t change the subject. Don’t rush them out of their sadness. Don’t offer solutions.

Instead, here are a few other ways to offer support gently and meaningfully:

  • Say their pet’s name.

  • Ask what they miss most.

  • Tell them you’re sorry.

  • Let them cry.

  • Let them not cry.

  • Let them remember.

Because when someone loses a pet, they’re not “just” mourning an animal. They’re grieving for a relationship, a rhythm and a presence that made the world feel kinder. What they need most is someone willing to treat that loss like it matters.

Fears that falling birth rates in US could lead to population collapse are based on faulty assumptions

Source: The Conversation – USA (3) – By Leslie Root, Assistant Professor of Research, Institute of Behavioral Science, University of Colorado Boulder

Unfortunately for demographers, birth rates are hard to predict far into the future. gremlin/E+ via Getty Images

Pronatalism – the belief that low birth rates are a problem that must be reversed – is having a moment in the U.S.

As birth rates decline in the U.S. and throughout the world, voices from Silicon Valley to the White House are raising concerns about what they say could be the calamitous effects of steep population decline on the economy. The Trump administration has said it is seeking ideas on how to encourage Americans to have more children as the U.S. experiences its lowest total fertility rate in history, down about 25% since 2007.

As demographers who study fertility, family behaviors and childbearing intentions, we can say with certainty that population decline is not imminent, inevitable or necessarily catastrophic.

The population collapse narrative hinges on three key misunderstandings. First, it misrepresents what standard fertility measures tell us about childbearing and makes unrealistic assumptions that fertility rates will follow predictable patterns far into the future. Second, it overstates the impact of low birth rates on future population growth and size. Third, it ignores the role of economic policies and labor market shifts in assessing the impacts of low birth rates.

Fertility fluctuations

Demographers generally gauge births in a population with a measure called the total fertility rate. The total fertility rate for a given year is an estimate of the average number of children that women would have in their lifetime if they experienced current birth rates throughout their childbearing years.

Fertility rates are not fixed – in fact, they have changed considerably over the past century. In the U.S., the total fertility rate rose from about 2 births per woman in the 1930s to a high of 3.7 births per woman around 1960. The rate then dipped below 2 births per woman in the late 1970s and 1980s before returning to 2 births in the 1990s and early 2000s.

Since the Great Recession that lasted from late 2007 until mid-2009, the U.S. total fertility rate has declined almost every year, with the exception of very small post-COVID-19 pandemic increases in 2021 and 2022. In 2024, it hit a record low, falling to 1.6. This drop is primarily driven by declines in births to people in their teens and early 20s – births that are often unintended.

But while the total fertility rate offers a snapshot of the fertility landscape, it is not a perfect indicator of how many children a woman will eventually have if fertility patterns are in flux – for example, if people are delaying having children.

Picture a 20-year-old woman today, in 2025. The total fertility rate assumes she will have the same birth rate as today’s 40-year-olds when she reaches 40. That’s not likely to be the case, because birth rates 20 years from now for 40-year-olds will almost certainly be higher than they are today, as more births occur at older ages and more people are able to overcome infertility through medically assisted reproduction.

A more nuanced picture of childbearing

These problems with the total fertility rate are why demographers also measure how many total births women have had by the end of their reproductive years. In contrast to the total fertility rate, the average number of children ever born to women ages 40 to 44 has remained fairly stable over time, hovering around two.

Americans continue to express favorable views toward childbearing. Ideal family size remains at two or more children, and 9 in 10 adults either have, or would like to have, children. However, many Americans are unable to reach their childbearing goals. This seems to be related to the high cost of raising children and growing uncertainty about the future.

In other words, it doesn’t seem to be the case that birth rates are low because people are uninterested in having children; rather, it’s because they don’t feel it’s feasible for them to become parents or to have as many children as they would like.

The challenge of predicting future population size

Standard demographic projections do not support the idea that population size is set to shrink dramatically.

One billion people lived on Earth 250 years ago. Today there are over 8 billion, and by 2100 the United Nations predicts there will be over 10 billion. That’s 2 billion more, not fewer, people in the foreseeable future. Admittedly, that projection is plus or minus 4 billion. But this range highlights another key point: Population projections get more uncertain the further into the future they extend.

Predicting the population level five years from now is far more reliable than 50 years from now – and beyond 100 years, forget about it. Most population scientists avoid making such long-term projections, for the simple reason that they are usually wrong. That’s because fertility and mortality rates change over time in unpredictable ways.

The U.S. population size is also not declining. Currently, despite fertility below the replacement level of 2.1 children per woman, there are still more births than deaths. The U.S. population is expected to grow by 22.6 million by 2050 and by 27.5 million by 2100, with immigration playing an important role.

Will low fertility cause an economic crisis?

A common rationale for concern about low fertility is that it leads to a host of economic and labor market problems. Specifically, pronatalists argue that there will be too few workers to sustain the economy and too many older people for those workers to support. However, that is not necessarily true – and even if it were, increasing birth rates wouldn’t fix the problem.

As fertility rates fall, the age structure of the population shifts. But a higher proportion of older adults does not necessarily mean the proportion of workers to nonworkers falls.

For one thing, the proportion of children under age 18 in the population also declines, so the number of working-age adults – usually defined as ages 18 to 64 – often changes relatively little. And as older adults stay healthier and more active, a growing number of them are contributing to the economy. Labor force participation among Americans ages 65 to 74 increased from 21.4% in 2003 to 26.9% in 2023 — and is expected to increase to 30.4% by 2033. Modest changes in the average age of retirement or in how Social Security is funded would further reduce strains on support programs for older adults.

What’s more, pronatalists’ core argument that a higher birth rate would increase the size of the labor force overlooks some short-term consequences. More babies means more dependents, at least until those children become old enough to enter the labor force. Children not only require expensive services such as education, but also reduce labor force participation, particularly for women. As fertility rates have fallen, women’s labor force participation rates have risen dramatically – from 34% in 1950 to 58% in 2024. Pronatalist policies that discourage women’s employment are at odds with concerns about a diminishing number of workers.

Research shows that economic policies and labor market conditions, not demographic age structures, play the most important role in determining economic growth in advanced economies. And with rapidly changing technologies like automation and artificial intelligence, it is unclear what demand there will be for workers in the future. Moreover, immigration is a powerful – and immediate – tool for addressing labor market needs and concerns over the proportion of workers.

Overall, there’s no evidence for Elon Musk’s assertion that “humanity is dying.” While the changes in population structure that accompany low birth rates are real, in our view the impact of these changes has been dramatically overstated. Strong investments in education and sensible economic policies can help countries successfully adapt to a new demographic reality.

Deportation tactics from 4 US presidents have done little to reduce the undocumented immigrant population

All modern U.S. presidents, both Republican and Democratic, have attempted to reduce the population of millions of undocumented immigrants. But their various strategies have not had significant results, with the population hovering around 11 million from 2005 to 2022.

President Donald Trump seeks to change that.

With harsh rhetoric that has sowed fear in immigrant communities, and policies that ignore immigrants’ due process rights, Trump has pursued deportation tactics that differ dramatically from those of any other modern U.S. president.

As a scholar who examines the history of U.S. immigration law and enforcement, I believe that it remains far from clear whether the Trump White House will significantly reduce the undocumented population. But even if the administration’s efforts fail, the fear and damage to the U.S. immigrant community will remain.

Presidents Bush and Obama

To increase deportations, in 2006 President George W. Bush began using workplace raids. Among these sweeps was the then-largest immigration workplace operation in U.S. history at a meat processing plant in Postville, Iowa in 2008.

U.S. Immigration and Customs Enforcement deployed 900 agents in Postville and arrested 398 employees, 98% of whom were Latino. They were chained together and arraigned in groups of 10 for felony criminal charges of aggravated identity theft, document fraud and use of stolen Social Security numbers. Some 300 were convicted, and 297 of them served jail sentences before being deported.

In 2008, Bush also initiated Secure Communities, a policy that sought to deport noncitizens – both lawful permanent residents as well as undocumented immigrants – who had been arrested for crimes. Some 2 million immigrants were deported during Bush’s two terms in office.

The Obama administration limited Secure Communities to focus on the removal of noncitizens convicted of felonies. It deported a record 400,000 noncitizens in fiscal year 2013, which led detractors to refer to President Barack Obama as the “Deporter in Chief.”

Obama also targeted recent entrants and national security threats and pursued criminal prosecutions for illegal reentry to the U.S. Almost all of these policies built on Bush’s, although Obama virtually abandoned workplace raids.

Despite these enforcement measures, Obama also initiated Deferred Action for Childhood Arrivals, or DACA, in 2012. The policy provided relief from deportation and gave work authorization to more than 500,000 undocumented immigrants who came to the United States as children.

Obama deported about 3 million noncitizens, but the size of the undocumented population did not decrease dramatically.

The first Trump administration and Biden

Trump’s first administration broke new immigration enforcement ground in several ways.

He began his presidency by issuing what was called a “Muslim ban” to restrict the entry into the U.S. of noncitizens from predominantly Muslim nations.

Early in Trump’s first administration, federal agents expanded immigration operations to include raids at courthouses, which previously had been off-limits.

In 2017, Trump tried to rescind DACA, but the Supreme Court rejected Trump’s effort in 2020.

In 2019, Trump implemented the Remain in Mexico policy that for the first time forced noncitizens who came to the U.S. border seeking asylum to wait in Mexico while their claims were being decided. He also invoked Title 42 in 2020 to close U.S. borders during the COVID-19 pandemic.

Trump succeeded in reducing legal immigration numbers during his first term. However, there is no evidence that his enforcement policies reduced the size of the overall undocumented population.

President Joe Biden sought to relax – although not abandon – some immigration enforcement measures implemented during Trump’s first term.

His administration slowed construction of the border wall championed by Trump. Biden also stopped workplace raids in 2021, and in 2023, he ended Title 42.

In 2023, Biden sought to respond to migration surges in a measured fashion, by temporarily closing ports of entry and increasing arrests.

In attempting to enforce the borders, his administration at times pursued tough measures. Biden continued deportation efforts directed at criminal noncitizens. Immigrant rights groups criticized his administration when armed Border Patrol officers on horseback were videotaped chasing Haitian migrants on the U.S.-Mexico border.

As of 2022, the middle of the Biden’s term, an estimated 11 million undocumented immigrants lived in the U.S.

A second chance

Since his second inauguration, Trump has pursued a mass deportation campaign through executive orders that are unprecedented in their scope.

In January 2025, he announced an expanded, expedited removal process for any noncitizen apprehended anywhere in the country – not just the border region, as had been U.S. practice since 1996.

In March, Trump issued a presidential proclamation to deport Venezuelan nationals who were members of the Tren de Aragua gang, designated a foreign terrorist organization by the State Department. In doing so, he invoked the Alien Enemies Act of 1798 – an act used three times in U.S. history during declared wars that empowers presidents to remove foreign nationals from countries at war with the U.S.

Declaring an “invasion” of migrants into the U.S. in June, Trump deployed the military to assist in immigration enforcement in Los Angeles.

Trump also sought to dramatically upend birthright citizenship, the Constitutional provision that guarantees citizenship to any person born in the U.S. He issued an executive order in January that would bar citizenship to people born in the U.S. to undocumented parents.

The birthright executive order has been challenged in federal court and is mostly likely working its way up to the Supreme Court.

Under the second Trump administration, immigration arrests are up, but actual deportation numbers are in flux.

ICE in June arrested the most people in a month in at least five years, roughly 30,000 immigrants. But deportations of noncitizens – roughly 18,000 – lagged behind those during the Obama administration’s record-setting year of 2013 in which more than 400,000 noncitizens were deported.

The gap between arrests and deportations shows the challenges the Trump administration faces in making good on his promised mass deportation campaign.

Undocumented immigrants often come to the U.S. to work or seek safety from natural disasters and mass violence.

These issues have not been seriously addressed by any modern U.S. president. Until it is, we can expect the undocumented population to remain in the millions.

Nana-Benz du Togo : comment les importations chinoises de tissus africains ont nui aux célèbres commerçantes

Source: The Conversation – in French – By Fidele B. Ebia, Postdoctoral fellow, Duke Africa Initiative, Duke University

La fabrication des tissus imprimés africains s’est déplacée vers la Chine au XXIe siècle. Bien qu’ils soient largement consommés dans les pays africains et symbolisent le continent, l’essor du « made in China » a porté un coup dur aux commerçantes africaines qui ont longtemps dominé la vente et la distritbution des ces tissus.

Pendant plusieurs décennies, Vlisco, le groupe textile néerlandais fondé en 1846 et dont les produits étaient fournis à l’Afrique de l’Ouest par des maisons de commerce européennes depuis la fin du XIXe siècle, a dominé la fabrication de ces tissus. Mais au cours des 25 dernières années, des dizaines d’usines chinoises ont commencé à fournir des tissus imprimés africains aux marchés d’Afrique de l’Ouest. Qingdao Phoenix Hitarget Ltd, Sanhe Linqing Textile Group et Waxhaux Ltd sont parmi les plus connues.

Nous avons mené une étude afin de déterminer comment l’essor des tissus fabriqués en Chine a affecté le commerce des tissus imprimés africains. Nous nous sommes concentrés sur le Togo. Bien que ce soit un petit pays avec une population de seulement 9,7 millions d’habitants, la capitale, Lomé, est la plaque tournante du commerce textile en Afrique de l’Ouest.

Nous avons mené plus de 100 entretiens avec des commerçants, des vendeurs de rue, des agents portuaires ou des courtiers, des représentants du gouvernement et des représentants d’entreprises manufacturières afin de comprendre comment leurs activités ont évolué.

Les textiles africains imprimés « Made in China » sont nettement moins chers et plus accessibles à une population plus large que les tissus Vlisco. Nos observations sur le célèbre marché Assigamé de Lomé ont révélé que les textiles africains imprimés chinois coûtent environ 9 000 CFA (16 dollars américains) pour six mètres, soit une tenue complète. Le wax hollandais (50 000 CFA ou 87 dollars américains) coûte plus de cinq fois plus cher.

Les données sont difficiles à obtenir, mais nos estimations suggèrent que 90 % des importations de ces tissus au port de Lomé en 2019 provenaient de Chine.

Un commerçant togolais résume ainsi l’attrait de ces produits :

Qui pourrait résister à un tissu qui ressemble au vrai Vlisco, mais qui coûte beaucoup moins cher ?

Notre étude montre comment l’arrivée des tissus fabriqués en Chine a fait perdre à Vlisco sa position dominante sur le marché. Elle a aussi brisé le monopole qu’avaient les commerçantes togolaises sur le commerce des tissus néerlandais.

Ces commerçantes, surnommés les Nana-Benz en raison des voitures de luxe qu’elles conduisaient, avaient, en dépit de leur petit nombre, un poids économique et politique énorme. Leur influence politique était telle qu’elles étaient les principaux soutiens du premier président du Togo, Sylvanus Olympio, lui-même ancien directeur de la United Africa Company, qui distribuait des tissus néerlandais.

En échange, Olympio et le général Gnassingbé Eyadéma, au pouvoir pendant de longues années, leur accordèrent des avantages politiques, tels que des impôts réduits, afin de soutenir leurs activités commerciales. Dans les années 1970, le commerce des tissus africains imprimés était considéré comme aussi important que l’industrie du phosphate, principal produit d’exportation.

Les Nana-Benz ont depuis été évincées, leur nombre passant de 50 à environ 20. De nouvelles commerçantes togolaises, connues sous le nom de Nanettes ou « petites Nanas », ont pris leur place. Si elles se sont taillé une place dans le commerce du textile avec la Chine, elles ont toutefois un statut économique et politique moins important. À leur tour, elles sont de plus en plus menacées par la concurrence chinoise, notamment dans le domaine du commerce et de la distribution.

Wax : les femmes togolaises derrière le succès du tissu


La Chine supplante les Pays-Bas

Depuis l’époque coloniale, les femmes commerçantes africaines ont joué un rôle essentiel dans la vente en gros et la distribution de tissus néerlandais sur les marchés d’Afrique de l’Ouest. À partir des années 1950, lorsque de nombreux pays de la région ont accédé à l’indépendance, le Grand Marché de Lomé – ou Assigamé – est devenu la plaque tournante du commerce des tissus imprimés africains.

Alors que les pays voisins, comme le Ghana, limitaient les importations dans le cadre de leurs efforts pour promouvoir l’industrie locale, les commerçantes togolaises avaient obtenu des conditions très avantageuses : faibles taxes et accès direct au port de Lomé.

Les commerçantes togolaises connaissaient mieux les goûts de la clientèle majoritairement féminine d’Afrique de l’Ouest que les créateurs néerlandais, principalement masculins. Les Nana-Benz ont activement participé au processus de production et de création des textiles imprimés africains. Elles choisissaient les motifs, donnaient des noms aux tissus, et savaient exactement ce qui faisait vendre leurs tissus.

Ce commerce leur a permis d’acquérir une telle richesse qu’elles ont été surnommées les « Nana-Benz » en référence aux voitures qu’elles achetaient pour collecter et transporter leurs marchandises.

L’exclusivité des Nana-Benz sur le commerce et la vente au détail de tissus imprimés africains sur les marchés d’Afrique de l’Ouest a été remise en cause. Alors que Vlisco a réagi à la baisse de ses revenus (plus de 30 % au cours des cinq premières années du XXIe siècle) due à la concurrence chinoise, le rôle des commerçantes togolaises dans la chaîne d’approvisionnement des tissus néerlandais a été réduit.

Le monopole de Nana-Benz a été aussi sur le commerce et la distribution des tissus hollandais. Avec l’arrivée massive des tissus chinois, les ventes de Vlisco ont chuté de plus de 30 % au début du 21e siècle. Cette situation a affaibli le rôle des commerçantes togolaises dans la chaîne d’approvisionnement des tissus néerlandais.

Vlisco a ouvert plusieurs boutiques en Afrique occidentale et centrale, à commencer par Cotonou (2008), Lomé (2008) et Abidjan (2009). Les Nana-Benz qui ont survécu – environ 20 sur les 50 d’origine – sont devenues des revendeuses sous contrat. Elles doivent désormais respecter des règles strictes sur les prix et les ventes.

Si les nouveaux négociantes togolaises, connues sous le nom de Nanettes, sont impliquées dans l’approvisionnement en textiles en provenance de Chine, leur poids économique et politique est moindre. Elles sont environ 60 à exercer cette activité.

Anciennes vendeuses de textiles et d’autres petits articles dans la rue, les Nanettes ont commencé à se rendre en Chine au début des années 2000 pour s’approvisionner en textiles imprimés africains. Elles participent à la commande et au conseil pour la fabrication de textiles imprimés africains en Chine et à leur distribution en Afrique.

Si beaucoup de Nanettes commandent des marques chinoises courantes, certaines possèdent et commercialisent leurs propres marques. Parmi celles-ci figurent des modèles désormais bien connus à Lomé et en Afrique de l’Ouest, tels que « Femme de Caractère », « Binta », « Prestige », « Rebecca Wax », « GMG » et « Homeland ».

Contrairement à leurs prédécesseurs (les Nana-benz), les Nanettes se taillent une plus petite part du marché en vendant des tissus chinois moins chers. Bien que les volumes commercialisés soient importants, les marges sont plus faibles en raison du prix de vente final beaucoup plus bas que celui des tissus néerlandais.

Après s’être approvisionnées en tissus imprimés africains en Chine, les Nanettes vendent en gros à des commerçants locaux indépendants ou « vendeurs », ainsi qu’à des commerçants des pays voisins. Ces derniers divisent leurs stocks et les revendent par petites quantités aux vendeurs de rue.

Tous les tissus imprimés africains provenant de Chine arrivent en Afrique de l’Ouest sous forme de produits incomplets, c’est-à-dire sous forme de rouleaux de tissus de six ou douze mètres. Les tailleurs et couturières locaux confectionnent ensuite des vêtements selon les goûts des consommateurs. Certains créateurs de mode ont également ouvert des boutiques où ils vendent des vêtements prêt-à-porter confectionnés à partir de rouleaux de tissus imprimés africains et adaptés au goût local. Ainsi, même si le monopole des Nana-Benz s’est affrité, une partie de la valeur ajoutée est captée au niveau local.

Depuis la pandémie de COVID-19, les acteurs chinois se sont davantage impliqués dans les activités commerciales, et pas seulement dans la fabrication. Cette évolution pourrait marginaliser des acteurs locaux, déjà exclus de la fabrication, du commerce et de la distribution, qui constituent les maillons de la chaîne de valeur. Le maintien de leur rôle, qui consiste à adapter les produits à la culture et aux tendances locales et à relier l’économie formelle et informelle, est essentiel non seulement pour les commerçants togolais, mais aussi pour l’économie dans son ensemble.

Faut-il jeter l’eau de la bouilloire entre chaque usage ? Voici ce que dit la science

Source: The Conversation – in French – By Faisal Hai, Professor and Head of School of Civil, Mining, Environmental and Architectural Engineering, University of Wollongong

La bouilloire est un appareil ménager indispensable dans de nombreux foyers. Comment ferait-on sans elle pour nos boissons chaudes ?

Mais peut-on réutiliser l’eau restée dans la bouilloire après la précédente utilisation ?

Bien que l’eau portée à ébullition soit désinfectée, vous avez peut-être entendu dire que faire bouillir l’eau plusieurs fois rendrait l’eau nocive et qu’il fallait donc vider la bouilloire à chaque nouvelle utilisation.

Ces affirmations s’appuient souvent sur l’idée que l’eau réchauffée entraînerait l’accumulation de substances prétendument dangereuses, notamment des métaux tels que l’arsenic ou des sels tels que les nitrates et le fluorure.

Ce n’est pas vrai. Pour comprendre pourquoi, examinons la composition de l’eau du robinet et ce qui se passe réellement lorsque nous la faisons bouillir.

Que contient l’eau du robinet ?

Prenons l’exemple de l’eau du robinet fournie par Sydney Water, le plus grand service public d’approvisionnement en eau d’Australie, qui alimente Sydney, les Blue Mountains et la région d’Illawarra.

D’après les données accessibles au public pour le trimestre janvier-mars 2025 pour la région d’Illawarra, voici les résultats moyens de la qualité de l’eau :

  • Le pH était légèrement alcalin.

  • La teneur en solides dissous totaux était suffisamment faible pour éviter l’entartrage des canalisations et des appareils électroménagers.

  • La teneur en fluorure était appropriée pour améliorer la santé dentaire.

  • Il s’agissait d’une eau « douce » avec une dureté totale inférieure à 40 mg de carbonate de calcium par litre.

L’eau contenait des traces de métaux tels que le fer et le plomb, des niveaux de magnésium suffisamment faibles pour ne pas être perceptibles au goût, et des niveaux de sodium nettement inférieurs à ceux des boissons gazeuses courantes.

Ces paramètres, ainsi que tous les autres paramètres de qualité surveillés, étaient bien inférieurs aux directives australiennes sur l’eau potable pendant cette période.

Même si vous utilisiez cette eau pour faire du thé, la faire bouillir à nouveau ne poserait aucun problème pour la santé. Voici pourquoi.

Voici comment éliminer certains polluants éternels de votre eau potable à domicile


Il est difficile de concentrer des niveaux aussi faibles de produits chimiques

Pour concentrer des substances dans l’eau, il faudrait évaporer une partie du liquide tout en conservant les produits chimiques. L’eau s’évapore à n’importe quelle température, mais la majorité de l’évaporation se produit au point d’ébullition, lorsque l’eau se transforme en vapeur.

Pendant l’ébullition, certains composés organiques volatils peuvent s’échapper dans l’air, mais la quantité de composés inorganiques (tels que les métaux et les sels) reste inchangée.

Même si porter l’eau à ébullition peut légèrement augmenter la concentration de certains composés inorganiques, les preuves montrent que ce n’est pas le cas dans des proportions suffisantes pour être dangereux.

Supposons que vous fassiez bouillir un litre d’eau du robinet dans une bouilloire le matin et que votre eau du robinet ait une teneur en fluorure de 1 mg par litre, ce qui est conforme aux directives australiennes.

Vous préparez une tasse de thé avec 200 ml d’eau bouillie. Vous préparez ensuite une autre tasse de thé dans l’après-midi en faisant bouillir à nouveau l’eau restante.

Dans les deux cas, si le chauffage a été arrêté peu après le début de l’ébullition, la perte d’eau par évaporation serait faible et la teneur en fluorure dans chaque tasse de thé serait similaire.

Mais supposons que lorsque vous préparez la deuxième tasse, vous laissez l’eau bouillir jusqu’à ce que 100 ml de l’eau contenue dans la bouilloire se soient évaporés. Même dans ce cas, la quantité de fluorure que vous consommeriez avec la deuxième tasse (0,23 mg) ne serait pas significativement plus élevée que celle que vous avez consommée avec la première tasse de thé (0,20 mg).

Il en va de même pour tous les autres minéraux ou substances organiques que l’eau du robinet pourrait contenir. Prenons l’exemple du plomb : l’eau fournie dans la région d’Illawarra, comme mentionné ci-dessus, avait une concentration en plomb inférieure à 0,0001 mg par litre. Pour atteindre une concentration en plomb dangereuse (0,01 mg par litre, selon les directives australiennes) dans une tasse d’eau, il faudrait faire bouillir environ 20 litres d’eau du robinet pour obtenir cette tasse de 200 ml.

Dans la pratique, cela est peu probable, car la plupart des bouilloires électriques sont conçues pour bouillir brièvement avant de s’éteindre automatiquement. Tant que votre eau est conforme aux normes de potabilité, vous ne pouvez pas vraiment la concentrer à des niveaux nocifs dans votre bouilloire.

Mais qu’en est-il du goût ?

Le fait que l’eau réchauffée affecte ou non le goût de vos boissons dépend entièrement des spécificités de votre approvisionnement en eau local et de vos préférences personnelles.

La légère modification de la concentration en minéraux, ou la perte d’oxygène dissous dans l’eau pendant l’ébullition peuvent affecter le goût de l’eau pour certaines personnes, bien qu’il existe de nombreux autres facteurs qui contribuent au goût de l’eau du robinet.

En conclusion, tant que l’eau contenue dans votre bouilloire était initialement conforme aux directives relatives à la potabilité de l’eau, elle restera potable même après avoir été bouillie à plusieurs reprises.

Beijing’s ‘plausible deniability’ on arms supply is quickly becoming implausible – and could soon extend to Iran

Source: The Conversation – Global Perspectives – By Linggong Kong, Ph.D. Candidate in Political Science, Auburn University

Could longtime allies have a closer relationship than meets the eye? Thomas Peter/Pool Photo via AP

China has long maintained that it does not supply arms to any party at war – a central tenet of its “noninterference” foreign policy. But in recent years, Beijing has repeatedly faced accusations of doing the opposite: providing direct military assistance to nations engaged in conflict, while publicly denying doing so and even adopting a position of diplomatic neutrality.

That has seemingly been the case for two of China’s closest allies: Russia in its war against Ukraine and Pakistan during its recent armed standoff with India in May.

Now, Beijing is facing scrutiny over alleged military links to Iran – a country engaged in a long-running shadow conflict with Israel that recently tipped into a short-lived hot war.

After the ceasefire that followed the 12-day war in the Middle East, China reportedly supplied batteries for surface-to-air missiles to Iran in exchange for oil. Such parts are a critical military need for Tehran after its air defense network was severely damaged by Israeli missiles.

The Chinese Embassy in Israel denied the reports, stating that China firmly opposes the proliferation of weapons of mass destruction and does not export arms to countries at war. But China’s Ministry of Foreign Affairs has yet to issue an official statement on the alleged transfer.

As an expert specializing in China’s grand strategy, I think it is highly possible that China would offer Iran military support while denying it publicly. Such plausible deniability would allow Beijing to assert military influence and showcase some of its hardware, while deflecting international criticism and preserving diplomatic flexibility.

But the tactic works only so far. As indirect evidence accumulates, as many suggest it is, such covert action may gradually develop into an open secret – leading to what scholars term “implausible deniability,” where denial is no longer credible even if it is still officially maintained.

China’s support for Russia’s war

Although Beijing has consistently said it is neutral in the Russia-Ukraine war that broke out in 2022, China has, in practice, quietly supported Russia. In part, that is because China shares the same strategic goal of challenging the Western-led international order.

Recently, Chinese Foreign Minister Wang Yi reportedly told European Union foreign policy chief Kaja Kallas that Beijing cannot afford to see Russia lose the war in Ukraine. He was said to have warned that a Russian defeat would likely bring the full force of U.S. strategic pressure to bear on China.

From Beijing’s perspective, Moscow plays a vital role in keeping the West preoccupied, offering China valuable strategic breathing room by diverting American attention and resources away from the Asia-Pacific region.

Beyond deepening trade relations that have become a lifeline for Moscow’s economy under Western sanctions, China has reportedly supplied Russia with large quantities of dual-use goods – goods that can be used for civilian and military purposes – to enhance both Moscow’s offensive and defensive capabilities, as well as to boost China’s military-industrial production. Beijing has also allegedly provided satellite imagery to assist Russia on the battlefield.

While the U.S. and Europe have repeatedly tried to call out China for aiding Russia militarily, Beijing has consistently denied such claims.

Most recently, on April 18, 2025, Ukraine formally accused China of directly supporting Russia and slapped sanctions on three Chinese-based firms that Kyiv said was involved in weapons production for the Russian war effort.

In what has become a common refrain, China’s Foreign Ministry rejected the Ukrainian accusation, reaffirming that China has never provided lethal weapons to any party in the conflict and reiterating its official stance of promoting a ceasefire and peace negotiations.

China’s quiet backing of Pakistan

Beijing has long presented itself as a neutral party in the India-Pakistan conflict, too, and has called for restraint on both sides and urged peaceful dialogue.

But in practice, China is allied with Pakistan. And the direct military support it has provided to Lahore appears driven by China’s desire to curb India’s regional influence, counterbalance the growing U.S.–India strategic partnership and protect the China–Pakistan Economic Corridor, a massive bilateral infrastructure project.

In the latest flare-up between India and Pakistan in May, Pakistan deployed Chinese-made J-10C fighter jets in combat for the first time, reportedly downing five Indian aircraft.

Pakistan’s air defense relied heavily on Chinese equipment during the short conflict, deploying Chinese-made surface-to-air missile systems, air-to-air missiles, advanced radar systems and drones for reconnaissance and strike operations. Overall, more than 80% of Pakistan’s military imports have come from China in the past five years.

In what would be a far more stark example of military support if proven true, the deputy chief of India’s army alleged that China had provided Pakistan with real-time intelligence on Indian troop movements during the conflict.

When asked to respond, a spokesperson for China’s Ministry of Foreign Affairs said they had no knowledge of the matter. They reaffirmed that China’s ties with Pakistan are not directed against any third party and reiterated Beijing’s long-standing position in favor of a peaceful resolution to any India–Pakistan dispute.

Extending ‘deniability’ to Iran?

Like with Russia and Pakistan, Iran has increasingly been seen as a partner to China.

In 2021, China and Iran signed a 25-year, US$400 billion comprehensive cooperation agreement that covered trade, energy and security, signaling the depth of their strategic relationship.

The accord was indicative of the strategic value Beijing places on Iran. From Beijing’s perspective, Tehran presents a counterbalance to the influence of the U.S. and its allies – especially Israel and Saudi Arabia – in the region and helps divert Western resources and attention away from China.

But recently, Tehran’s position in the region has become far weaker. Not only has its air defense infrastructure suffered badly in the confrontations with Israel, but its regional proxies and allies – Hamas, Hezbollah and the Assad regime in Syria – have either been devastated by Israel or collapsed altogether.

Under these circumstances, it is strategically compelling for Beijing to provide support to Tehran in order to maintain regime stability.

Indeed, Beijing has frequently circumvented sanctions on Iranian energy, with an estimated 90% of Iran’s oil exports still going to China.

Although Beijing did not extend any substantive support to Iran during the 12-day war, reports have abounded since that Iran is looking to China as an alternative supplier of its defense needs. The thinking here is that Russia, Tehran’s traditional military partner, is no longer able to provide sufficient, quality defense equipment to Iran. Some influential social media posters in China have gone as far as advocating for direct military sales by Beijing.

If China does do this, I believe it is likely to follow the same playbook it has used elsewhere by denying involvement publicly while covertly providing assistance.

Doing so allows China to maintain diplomatic ties with Iran’s regional rivals, such as Israel and Saudi Arabia, while simultaneously benefiting from a turbulent Middle East that distracts Washington and grants Beijing strategic breathing room.

China’s use of plausible deniability reflects a broader strategic ambition. Namely, it wants to assert influence in key regional conflicts without triggering open backlash. By quietly supporting partners while maintaining a facade of neutrality, Beijing aims to undermine Western dominance, stretch U.S. strategic focus and secure its own interests – and all while avoiding the risks and responsibilities of open military alignment.

¿Qué significa el fracaso de las conversaciones de paz para la catástrofe humanitaria en Gaza?

Source: The Conversation – (in Spanish) – By Ali Mamouri, Research Fellow, Middle East Studies, Deakin University

Los esfuerzos por poner fin al implacable asedio de Gaza han sufrido un revés con el abrupto fin de las conversaciones de paz en Catar.

Tanto Estados Unidos como Israel han retirado sus equipos negociadores, acusando a Hamás de «falta de voluntad para alcanzar un alto el fuego».

El enviado especial del presidente estadounidense Donald Trump, Steve Witkoff, declaró que parece que Hamás nunca ha querido llegar a un acuerdo:

Aunque los mediadores han hecho un gran esfuerzo, Hamás no parece estar coordinado ni actuar de buena fe. Ahora consideraremos opciones alternativas para traer a los rehenes a casa e intentar crear un entorno más estable para la población de Gaza.

Este decepcionante desenlace coincide con el temor creciente a una hambruna generalizada en Gaza y con la decisión histórica de Francia de reconocer oficialmente al Estado palestino.

El presidente francés, Emmanuel Macron, afirma que no hay otra alternativa por el bien de la seguridad en Oriente Medio:

Fiel a su compromiso histórico con una paz justa y duradera en Oriente Medio, he decidido que Francia reconocerá al Estado de Palestina.

¿Qué significarán estos acontecimientos para el conflicto en Gaza y la seguridad general en Oriente Medio?

«Catástrofe humanitaria»

El fracaso de la tregua significa que no se vislumbra el fin del asedio israelí de Gaza, que ha devastado el territorio durante más de 21 meses.

Según la agencia de la ONU para los refugiados palestinos, la UNRWA, más de 100 personas, en su mayoría niños, han muerto de hambre. Uno de cada cinco niños de la ciudad de Gaza está desnutrido, y el número de casos aumenta cada día.

El comisionado general Philippe Lazzarini afirma que, con la escasa ayuda alimentaria que llega a Gaza:

Los habitantes de Gaza no son ni vivos ni muertos, son cadáveres andantes […] la mayoría de los niños que ven nuestros equipos están demacrados, débiles y corren un alto riesgo de morir si no reciben el tratamiento que necesitan urgentemente.

La ONU y más de 100 organizaciones humanitarias culpan al bloqueo israelí de casi toda la ayuda que llega al territorio por la falta de alimentos.

Lazzarini afirma que la UNRWA tiene 6 000 camiones con suministros de emergencia esperando en Jordania y Egipto. Insta a Israel, que sigue culpando a Hamás de los casos de malnutrición, a que permita la entrada de la ayuda humanitaria en Gaza.

Propuesta de acuerdo de alto el fuego

La última propuesta de alto el fuego estaba a punto de ser aceptada por ambas partes.

Incluía una tregua de 60 días, durante la cual Hamás liberaría a diez rehenes israelíes vivos. A cambio, Israel liberaría a varios prisioneros palestinos y aumentaría considerablemente la ayuda humanitaria a Gaza.

Durante el alto el fuego, ambas partes entablarían negociaciones para alcanzar una tregua duradera.

Aunque aún no se conocen los detalles concretos de los puntos conflictivos, las declaraciones anteriores de ambas partes sugieren que el desacuerdo se centra en lo que sucedería tras un alto el fuego temporal.

Según se informa, Israel pretende mantener una presencia militar permanente en Gaza para poder reanudar rápidamente las operaciones si fuera necesario. Por el contrario, Hamás exige una vía hacia el fin total de las hostilidades.

La falta de confianza mutua ha empañado drásticamente las negociaciones.

Desde la perspectiva de Israel, cualquier alto el fuego debe impedir que Hamás recupere el control de Gaza, ya que esto permitiría al grupo reconstruir su poder y lanzar potencialmente otro ataque transfronterizo.

Sin embargo, Hamás ha afirmado en repetidas ocasiones que está dispuesto a entregar el poder a cualquier otro grupo palestino que persiga un Estado palestino basado en las fronteras de 1967. Esto podría incluir a la Autoridad Nacional Palestina (ANP), que gobierna Cisjordania y reconoce desde hace tiempo a Israel.

Apoyo a un Estado palestino

Los líderes israelíes han apoyado ocasionalmente de boquilla un Estado palestino. Sin embargo, han descrito dicha entidad como «menos que un Estado», una formulación que no satisface ni las aspiraciones palestinas ni las normas jurídicas internacionales.

En respuesta al empeoramiento de la situación humanitaria, algunos países occidentales han dado pasos para reconocer plenamente un Estado palestino, considerándolo un paso hacia la resolución permanente de uno de los conflictos más prolongados de Oriente Medio.

El anuncio de Macron supone un avance importante.

Francia es ahora la potencia occidental más destacada en adoptar esta postura. Se suma así a más de 140 países, entre ellos más de una docena de Europa, que ya han reconocido la condición de Estado.

Aunque se trata de una medida simbólica, aumentará la presión diplomática sobre Israel en medio de la guerra y la crisis humanitaria que se vive en Gaza.

Sin embargo, el anuncio fue inmediatamente condenado por el primer ministro israelí, Benjamin Netanyahu, quien afirmó que el reconocimiento «recompensa el terrorismo» y “sería una plataforma de lanzamiento para aniquilar a Israel, no para vivir en paz junto a él”.

¿Anexionarse Gaza?

Un Estado palestino es inaceptable para Israel.

Recientemente se han presentado más pruebas en una reveladora entrevista televisiva del ex primer ministro israelí Ehud Barak, quien afirmó que Netanyahu había empoderado deliberadamente a Hamás para bloquear una solución de dos Estados.

En cambio, cada vez hay más pruebas de que Israel está intentando anexionarse la totalidad del territorio palestino y reubicar a los palestinos en países vecinos.

Dada la incertidumbre actual, parece poco probable que se alcance un nuevo alto el fuego en un futuro próximo, sobre todo porque sigue sin estar claro si la retirada de Estados Unidos de las conversaciones fue un cambio real de política o una mera táctica estratégica de negociación.

3 reasons young people are more likely to believe conspiracy theories – and how we can help them discover the truth

Source: The Conversation – Global Perspectives – By Jean-Nicolas Bordeleau, Research Fellow, Jeff Bleich Centre for Democracy and Disruptive Technologies, Flinders University

Conspiracy theories are a widespread occurrence in today’s hyper connected and polarised world.

Events such as Brexit, the 2016 and 2020 United States presidential elections, and the COVID pandemic serve as potent reminders of how easily these narratives can infiltrate public discourse.

The consequences for society are significant, given a devotion to conspiracy theories can undermine key democratic norms and weaken citizens’ trust in critical institutions. As we know from the January 6 riot at the US Capitol, it can also motivate political violence.

But who is most likely to believe these conspiracies?

My new study with Daniel Stockemer of the University of Ottawa provides a clear and perhaps surprising answer. Published in Political Psychology, our research shows age is one of the most significant predictors of conspiracy beliefs, but not in the way many might assume.

People under 35 are consistently more likely to endorse conspiratorial ideas.

This conclusion is built on a solid foundation of evidence. First, we conducted a meta analysis, a “study of studies”, which synthesised the results of 191 peer-reviewed articles published between 2014 and 2024.

This massive dataset, which included over 374,000 participants, revealed a robust association between young age and belief in conspiracies.

To confirm this, we ran our own original multinational survey of more than 6,000 people across six diverse countries: Australia, Brazil, Canada, Germany, the US and South Africa.

The results were the same. In fact, age proved to be a more powerful predictor of conspiracy beliefs than any other demographic factor we measured, including a person’s gender, income, or level of education.

Why are young people more conspiratorial?

Having established conspiracy beliefs are more prevalent among younger people, we set out to understand why.

Our project tested several potential factors and found three key reasons why younger generations are more susceptible to conspiracy theories.

1. Political alienation

One of the most powerful drivers we identified is a deep sense of political disaffection among young people.

A majority of young people feel alienated from political systems run by politicians who are two or three generations older than them.

This under representation can lead to frustration and the feeling democracy isn’t working for them. In this context, conspiracy theories provide a simple, compelling explanation for this disconnect: the system isn’t just failing, it’s being secretly controlled and manipulated by nefarious actors.

2. Activist style of participation

The way young people choose to take part in politics also plays a significant role.

While they may be less likely to engage in traditional practices such as voting, they are often highly engaged in unconventional forms of participation, such as protests, boycotts and online campaigns.

These activist environments, particularly online, can become fertile ground for conspiracy theories to germinate and spread. They often rely on similar “us versus them” narratives that pit a “righteous” in-group against a “corrupt” establishment.

3. Low self-esteem

Finally, our research confirmed a crucial psychological link to self-esteem.

For individuals with lower perceptions of self worth, believing in a conspiracy theory – blaming external, hidden forces for their problems – can be a way of coping with feelings of powerlessness.

This is particularly relevant for young people. Research has long shown self esteem tends to be lower in youth, before steadily increasing with age.

What can be done?

Understanding these root causes is essential because it shows simply debunking false claims is not a sufficient solution.

To truly address the rise of conspiracy theories and limit their consequences, we must tackle the underlying issues that make these narratives so appealing in the first place.

Given the role played by political alienation, a critical step forward is to make our democracies more representative. This is best illustrated by the recent election of Labor Senator Charlotte Walker, who is barely 21.

By actively working to increase the presence of young people in our political institutions, we can help give them faith that the system can work for them, reducing the appeal of theories which claim it is hopelessly corrupt.

More inclusive democracy

This does not mean discouraging the passion of youth activism. Rather, it is about empowering young people with the tools to navigate today’s complex information landscape.

Promoting robust media and digital literacy education could help individuals critically evaluate the information they encounter in all circles, including online activist spaces.

The link to self-esteem also points to a broader societal responsibility.

By investing in the mental health and wellbeing of young people, we can help boost the psychological resilience and sense of agency that makes them less vulnerable to the simplistic blame games offered by conspiracy theories.

Ultimately, building a society that is resistant to misinformation is not about finding fault with a particular generation.

It is about creating a stronger, more inclusive democracy where all citizens, especially the young, feel represented, empowered, and secure.
