As Russian bombs continued to pound Ukraine, a different conflict has blown up over plans to end that almost four-year-long war. The Trump administration on Nov. 20, 2025, formally presented Ukraine with a 28-point proposal to end the war, and President Donald Trump announced the country had until Thanksgiving to sign it. But Ukraine and its European and U.S. allies said the plan heavily favored Russia, requiring Ukraine to give up territory not even held by Russia, diminish the size of its military and, ultimately, place its long-term sovereignty at risk. The Trump administration was accused by policy experts and some lawmakers of fashioning a plan to serve Russia’s interests, and Secretary of State Marco Rubio got enmeshed in an argument with U.S. senators over whether the U.S. or Russia had authored the document. On Nov. 23, Ukrainian and U.S. officials held talks in Geneva, which Rubio declared were “productive and meaningful,” and those negotiations continue. The Conversation U.S. politics editor Naomi Schalit asked longtime diplomat Donald Heflin, now teaching at Tufts University’s Fletcher School, to help make sense of the chaotic events.

I have a whole list of questions to ask you, but my first question is what on earth is going on?

It’s hard to say. Ever since the Trump administration took power for the second time, it’s alternated between leaning towards Russia in this war or being more neutral, with occasional leaning towards Ukraine. They go back and forth.

This particular peace plan gives Russia a lot at once. It gets the size of the Ukrainian army cut down from 800,000-plus to 600,000, when the country is barely hanging on defending itself with 800,000 troops. Russia gets land, including land that it has conquered. A lot of people expected that might be one of the conditions of a Ukraine-Russia peace deal. But this also gives Russia land that it hasn’t taken yet and may never take.

It bars Ukraine from seeking NATO membership. That’s not a huge surprise. That was probably always going to be part of an eventual deal. Ukraine gets security guarantees from the West. Unfortunately, the U.S. gave ironclad security guarantees in 1994 when Ukraine gave up its nuclear weapons voluntarily. It’s been invaded by Russia twice since then, in 2014 and 2022. So our security guarantees really don’t mean a whole lot in that area of the world.

And there’s more, right?

I think this is the most important part, what Putin is looking for more than anything else. Russia gets released from economic sanctions and it rejoins the group of G7 industrialized countries.

Putin’s economy is under a lot of stress. The cash that would flow in for the sale of Russian goods, particularly energy, would enable him to build a whole new army from scratch, if he needed to. That’s a huge strategic advantage. This would be a major shot in the arm for the Russian economy and for the Russian war economy.

So this is a very pro-Russian deal, unless it’s modified heavily, and there’s argument in Washington now whether the Russians just plain drafted it, or whether our State Department drafted it but for some reason leaned heavily towards Russia.

I’m inclined to think the original draft came from the Russians. It’s just too loaded up with the stuff that they want.

There was a fair amount of confusing back-and-forth on Nov. 23 that Rubio had told some senators that, in fact, the plan wasn’t generated by the United States, that it reflected a Russian wish list. The senators revealed this publicly. Then a State Department spokesman called that claim “blatantly false.” You’re a former diplomat. When you see that kind of thing happening, what do you think?

It’s amateur hour. We’ve seen this before. With this administration, it puts a lot of very amateurish people – Rubio’s not one of them – in place in important offices, like Steve Witkoff, the special envoy for Russia and Ukraine who is also the special envoy for the Middle East. And they’ve gotten rid of all the professionals. They either just fired some or ran some off.

So you know, the problem here is implementation. Politicians can have great thoughts, but they usually then turn to the professionals and say, “Here’s what I’m thinking.” The people they would turn to are gone. And that was their own doing – the left hand doesn’t know what the right hand is doing.

How might that affect the ultimate goal, which is peace?

This is a very delicate situation that calls for delicate peace talks from professional diplomats. There are a couple of things that need to happen and aren’t happening very much. First off, this is a war in Eastern Europe. Europe should be very involved now. They lean against Russia, so they probably can’t be honest brokers, but they need to be involved in every step of this process. If there’s going to be any rebuilding of Ukraine, Europe’s going to have to help with that. If there’s going to be pressure on Russia, Europe buys a lot of its goods, especially energy. They’re just a necessary player, and they haven’t been included.

What else?

The other is that when people have these great ideas, normally they would turn to their professionals. Those professionals would then talk to the professionals on the other side or other sides. Staff work would be done, then your presidents or your prime ministers or your secretaries of state would meet and hammer out the deal.

None of that’s happening in this process. People are having great thoughts and getting on planes, and that’s not a recipe for a permanent peace deal.

Europe is champing at the bit to try to get involved in this, because they’ve got professional diplomats still in place, and it affects them.

Why is this happening now?

The timing of all this is really interesting. Winter’s coming, and Northern Europe, particularly Germany, is very dependent on Russian natural gas to heat their homes. These sanctions against Russia make that difficult. They make it more expensive. Should Russia decide it wanted to play hardball, it could cut off its natural gas in Northern Europe, and people in Germany would be freezing in the dark this winter. This timing is not an accident.

Trump said he wanted an agreement by Thanksgiving. Is that a reasonable requirement of a process to bring peace after a multiyear war?

No, it’s not. I don’t know if they even realize this in the
Trump administration, but that’s another sign – just as we had ahead of the Alaska Summit between Putin and Trump – that this isn’t really about trying to make peace. It’s for show and to get credit. In a war that’s been going on now for almost four years, you don’t say, “OK, within the next week, come up with a very complicated peace deal and sign off on it and it’s going to stick.” That’s just not the way it works.

More than half of new articles on the internet are being written by AI – is human writing headed for extinction?

The line between human and machine authorship is blurring, particularly as it’s become increasingly difficult to tell whether something was written by a person or AI.

Now, in what may seem like a tipping point, the digital marketing firm Graphite recently published a study showing that more than 50% of articles on the web are being generated by artificial intelligence.

As a scholar who explores how AI is built, how people are using it in their everyday lives, and how it’s affecting culture, I’ve thought a lot about what this technology can do and where it falls short.

If you’re more likely to read something written by AI than by a human on the internet, is it only a matter of time before human writing becomes obsolete? Or is this simply another technological development that humans will adapt to?

It isn’t all or nothing

Thinking about these questions reminded me of Umberto Eco’s essay “Apocalyptic and Integrated,” which was originally written in the early 1960s. Parts of it were later included in an anthology titled “Apocalypse Postponed,” which I first read as a college student in Italy.

In it, Eco draws a contrast between two attitudes toward mass media. There are the “apocalyptics” who fear cultural degradation and moral collapse. Then there are the “integrated” who champion new media technologies as a democratizing force for culture.

Back then, Eco was writing about the proliferation of TV and radio. Today, you’ll often see similar reactions to AI.

Yet Eco argued that both positions were too extreme. It isn’t helpful, he wrote, to see new media as either a dire threat or a miracle. Instead, he urged readers to look at how people and communities use these new tools, what risks and opportunities they create, and how they shape – and sometimes reinforce – power structures.

While I was teaching a course on deepfakes during the 2024 election, Eco’s lesson also came back to me. Those were days when some scholars and media outlets were regularly warning of an imminent “deepfake apocalypse.”

Would deepfakes be used to mimic major political figures and push targeted disinformation? What if, on the eve of an election, generative AI was used to mimic the voice of a candidate on a robocall telling voters to stay home?

Those fears weren’t groundless: Research shows that people aren’t especially good at identifying deepfakes. At the same time, they consistently overestimate their ability to do so.

In the end, though, the apocalypse was postponed. Post-election analyses found that deepfakes did seem to intensify some ongoing political trends, such as the erosion of trust and polarization, but there’s no evidence that they affected the final outcome of the election.

Listicles, news updates and how-to guides

Of course, the fears that AI raises for supporters of democracy are not the same as those it creates for writers and artists.

For them, the core concerns are about authorship: How can one person compete with a system trained on millions of voices that can produce text at hyper-speed? And if this becomes the norm, what will it do to creative work, both as an occupation and as a source of meaning?

It’s important to clarify what’s meant by “online content,” the phrase used in the Graphite study, which analyzed over 65,000 randomly selected articles of at least 100 words on the web. These can include anything from peer-reviewed research to promotional copy for miracle supplements.

A closer reading of the Graphite study shows that the AI-generated articles consist largely of general-interest writing: news updates, how-to guides, lifestyle posts, reviews and product explainers.

The primary economic purpose of this content is to persuade or inform, not to express originality or creativity. Put differently, AI appears to be most useful when the writing in question is low-stakes and formulaic: the weekend-in-Rome listicle, the standard cover letter, the text produced to market a business.

A whole industry of writers – mostly freelance, including many translators – has relied on precisely this kind of work, producing blog posts, how-to material, search engine optimization text and social media copy. The rapid adoption of large language models has already displaced many of the gigs that once sustained them.

Collaborating with AI

The dramatic loss of this work points toward another issue raised by the Graphite study: the question of authenticity, not only in identifying who or what produced a text, but also in understanding the value that humans attach to creative activity.

How can you distinguish a human-written article from a machine-generated one? And does that ability even matter?

Over time, that distinction is likely to grow less significant, particularly as more writing emerges from interactions between humans and AI. A writer might draft a few lines, let an AI expand them and then reshape that output into the final text.

This article is no exception. As a non-native English speaker, I often rely on AI to refine my language before sending drafts to an editor. At times the system attempts to reshape what I mean. But once its stylistic tendencies become familiar, it becomes possible to avoid them and maintain a personal tone.

Also, artificial intelligence is not entirely artificial, since it is trained on human-made material. It’s worth noting that even before AI, human writing has never been entirely human, either. Every technology, from parchment and stylus paper to the typewriter and now AI, has shaped how people write and how readers make sense of it.

Another important point: AI models are increasingly trained on datasets that include not only human writing but also AI-generated and human–AI co-produced text.

This has raised concerns about their ability to continue improving over time. Some commentators have already described a sense of disillusionment following the release of newer large models, with companies struggling to deliver on their promises.

Human voices may matter even more

But what happens when people become overly reliant on AI in their writing?

Some studies show that writers may feel more creative when they use artificial intelligence for brainstorming, yet the range of ideas often becomes narrower. This uniformity affects style as well: These systems tend to pull users toward similar patterns of wording, which reduces the differences that usually mark an individual voice. Researchers also note a shift toward Western – and especially English-speaking – norms in the writing of people from other cultures, raising concerns about a new form of AI colonialism.

In this context, texts that display originality, voice and stylistic intention are likely to become even more meaningful within the media landscape, and they may play a crucial role in training the next generations of models.

If you set aside the more apocalyptic scenarios and assume that AI will continue to advance – perhaps at a slower pace than in the recent past – it’s quite possible that thoughtful, original, human-generated writing will become even more valuable.

Put another way: The work of writers, journalists and intellectuals will not become superfluous simply because much of the web is no longer written by humans.

From invasive species tracking to water security – what’s lost with federal funding cuts at US Climate Adaptation Science Centers

When the Trump administration began freezing federal funding for climate and ecosystem research, one of the programs hit hard was ours: the U.S. Geological Survey’s Climate Adaptation Science Centers.

These nine regional centers help fish, wildlife, water, land – and, importantly, people – adapt to rising global temperatures and other climate shifts.

The centers have been helping to track invasive species, protect water supplies and make agriculture more sustainable in the face of increasing drought conditions. They’re improving wildfire forecasting, protecting shorelines and saving Alaska salmon, among many other projects.

All of this work happens through partnerships: Scientists, many of them affiliated with universities, team up with public and private resource managers – the people who manage water supplies, wildlands, recreation areas, shorelines and other natural resources – to develop the research and solutions those managers need.

But in spring 2025, after 15 years of operation of the centers, the president’s proposed federal budget zeroed out funding for them. Federal workers at the centers were threatened with layoffs.

Three of the nine regional centers – covering the South Central, Pacific Islands and Northeast regions – were left unfunded when the Office of Management and Budget withheld and then blocked funds Congress had already appropriated.

In spite of these challenges, we have hope that the work will eventually continue. Congress’ proposed budgets in both the U.S. House and Senate recommend fully funding the Climate Adaptation Science Centers, and there’s a reason: Natural resources managers and the public have consistently told their elected officials that the work is important.

Here are three examples of projects in regions where funding has been blocked that show why resource managers are speaking up.

Sustainable water supplies in arid lands

In south-central Texas, the Edwards Aquifer Authority is responsible for providing sustained water resources for 2.5 million people in cities such as San Antonio and Uvalde. It also maintains the groundwater-fed springs that support threatened and endangered species.

In recent decades, however, both heavy rainfall and prolonged, intense droughts have increased uncertainty about how much water will be available from the aquifer.

At the South Central Climate Adaptation Science Center, researchers from the University of Oklahoma teamed up with the aquifer authority to develop high-resolution climate projections for assessing future changes to groundwater recharge and ecologically sensitive springs.

The climate projections are helping the authority determine whether its existing drought-mitigation practices are effective for sustaining freshwater springs and groundwater levels.

Losing funding for the Climate Adaptation Science Center means this technical guidance for water management and many other projects in the region are no longer available.

Stalled science doesn’t just hurt Texas. Many arid and semi-arid regions of the U.S. rely on aquifers to provide water supplies for homes, businesses and agriculture, and they need this type of research to maintain water security.

Solutions for agriculture and fire protection

On the Hawaiian island of O’ahu, up to 40% of agricultural land is unmanaged and unplanted pasture that is often invaded by non-native grasses. These grasses increase fire risk as the islands face more intense and longer-lasting droughts.

The Pacific Islands Climate Adaptation Science Center has been working on a solution to help restore fallow lands through agroforestry, in which farmers grow crops among trees, mirroring Indigenous practices.

Climate Adaptation Science Center researchers at the University of Hawai’i Mānoa partnered with Kākoʻo ʻŌiwi, a nonprofit organization that is restoring Indigenous food systems, to identify lands that will remain suitable for agroforestry even under worsening drought caused by climate change. The research has shown how management practices can increase soil health and increase the soil’s carbon storage.

Since 2019, researchers have taught hundreds of volunteers from the community and student groups about restoration practices that include food production, forest conservation and climate resilience.

Lost funding for Climate Adaptation Science Centers put the brakes on science that supports local communities.

Managing invasive species in a warming world

Invasive species cost the U.S. economy an estimated US$10 billion a year in damage to crops, forests and ecosystems. At the same time, climate change is increasing the range of many invasive species and making them harder to control.

In 2016, researchers from the Northeast Climate Adaptation Science Center at the University of Massachusetts Amherst learned that resource managers were concerned about how climate change would affect invasive species ranges. To understand and address the needs of resource managers, Climate Adaptation Science Center researchers created the Regional Invasive Species and Climate Change Network, which has become a primary source for mapping invasive species’ movement and sharing invasive species research across the region.

Climate Adaptation Science Center researchers conducted a series of projects to identify invasive plants expanding into northern and southern New England and mid-Atlantic states. The results have helped the state of Massachusetts update its invasive plant risk assessment and expanded regulators’ lists of invasive species to prohibit from sales in New York and Maine.

States recently asked the center’s researchers to develop a database of current and emerging invasive plants across the Northeast to help them build consistent and proactive defenses against emerging invasive species. Stalled funding has also stalled this project.

These are the kind of real-world solutions that federal funding cuts are stopping. When that work disappears, it leaves America and Americans more vulnerable to climate change.

Nonprofit news outlets are often scared that selling ads could jeopardize their tax-exempt status, but IRS records show that’s been rare

Although advertising revenue largely sustained the news media in the 20th century, it’s been harder to come by in the digital age. News media outlets just aren’t as important these days for advertisers when they can reach potential customers so many other ways, including through social media.

Some news outlets are relying more on subscription revenue. But that can also be a tough sell when readers have so many alternatives – often free – for finding news, if they’re even looking for it at all.

Increasingly, local news media outlets are adopting nonprofit models to be able to obtain grants from foundations and donations from individuals as new revenue sources.

At the same time, some nonprofit news leaders have avoided selling ads because the IRS has said their organizations would have to pay taxes on that revenue. They have also heard that selling too many ads might jeopardize their tax-exempt status altogether.

My research suggests that they need not worry about that – although, given recent threats by the Trump administration against Harvard University and other nonprofits, they may have reasons to be wary.

Encouraging earned revenue

I’m a former public radio journalist who now researches the nonprofit news sector.

I interviewed 23 nonprofit news leaders in 2023 about their fundraising practices. I also reviewed hundreds of 990 forms that most nonprofits are required to file annually with the IRS.

In early 2025, I published a study that found most nonprofit news leaders still depended heavily on foundations and individual donors. That’s despite calls from foundations and the Institute for Nonprofit News, an organization representing these media outlets, that they should diversify their revenue sources.

The Institute for Nonprofit News especially encourages news nonprofits to consider adding earned revenue. That category can include lots of things, but most often it means selling ads. The nonprofit news leaders I spoke with had mixed feelings about that.

Taxing unrelated business income

The philanthropic dollars that charitable nonprofits get from foundations, individual donors and corporations are exempt from taxes. But their earned revenue from sources such as advertising, sponsorships or ticketed events is often taxable.

That’s because U.S. tax law requires nonprofits to pay taxes on income deemed to be “not substantially related” to their public service missions.

Take, for example, money that a nonprofit museum earns through its gift shop. The government taxes that as unrelated business income so nonprofits don’t get an unfair edge over their for-profit competitors.

Money raised through ad sales has also historically counted as unrelated business income for nonprofits, according to the IRS. Some nonprofit news leaders say that’s not how it should be.

Some news nonprofits are directly challenging the traditional classification of advertising revenue as unrelated business income.

For example, the San Antonio Report, a nonprofit news outlet, reported receiving US$361,649 in advertising revenue in tax year 2022. But the organization did not pay taxes on it, because it identifies advertising as part of its mission. In fact, a Supreme Court ruling in the 1986 United States v. American College of Physicians case left open the possibility that advertising could be a tax-exempt form of revenue if it had an “educational function” related to the nonprofit’s purpose.

Selling ads anyway

Nonprofit news leaders not trying to challenge that classification still had reason to be concerned about running paid ads.

The IRS has warned it could revoke the tax-exempt status of nonprofits that had too much unrelated business income in their portfolios. That’s one of the top six reasons organizations lose their nonprofit status, according to the IRS. Other reasons include failure to serve an exempt purpose, lobbying, political campaigning, mission drift and failure to complete annual 990 forms.

How much unrelated business income is too much? The IRS has not provided clear guidance on this, despite pleas from local nonprofit news advocates.

One editor I interviewed, whose free weekly newspaper had recently converted from a for-profit enterprise to a nonprofit, lamented that her copious ad portfolio could put her tax-exempt status in jeopardy. Ads had always been part of what readers appreciated about her newspaper, she said – it was how they learned about restaurants and nightlife.

Some tax advisers recommend that nonprofits keep unrelated business income below 25% of their total revenue. But the ambiguity is enough to make some nonprofit news leaders prefer to not get any at all.

Some local news nonprofits are selling ads, despite their reservations about the potential tax impact and the potential threat of the IRS revoking their tax-exempt status. Of the Institute for Nonprofit News’ roughly 201 local newsroom members, 21 reported earning at least $1,000 in unrelated business income in the most recent year for which data was available when I conducted these interviews – usually 2022 or 2023. That happens to be the minimum reportable amount.

Paying no taxes

Only three of these 21 local news nonprofits paid taxes on their advertising revenue – and the ones that paid did so at reduced amounts. The outlets were largely able to avoid taxes due to exemptions the IRS allows nonprofits to claim for advertising-related expenses, such as commissions, agency fees and production. Several news nonprofits were also able to deduct readership costs, such as printing and distribution.

Local news nonprofits also appeared not to draw the ire of the IRS for accepting too much advertising revenue. While most reported unrelated business income that amounted to less than 25% of their total revenue, five news nonprofits did exceed that percentage, sometimes by quite a bit.

Rarely revoking tax exemptions

It turns out the IRS rarely revokes the tax-exempt status of charitable nonprofits of any kind for collecting too much unrelated business income.

IRS records indicate that the most common reason for revocations was the failure of nonprofits to file their 990 forms annually.

Not doing so for three years in a row triggers an automatic revocation, which can be reversed if nonprofits get back into compliance by belatedly filing their overdue paperwork. Revocations for all other reasons, including excessive unrelated business income, have impacted less than 0.1% of nonprofits, according to my analysis of IRS records.

In other words, two common concerns about advertising expressed by the nonprofit news leaders I interviewed – the potential tax burden and the risk of running afoul of the IRS – appear to have been unfounded.

At the same time, it can be hard to keep up with what might run afoul of IRS rules.

Starting in April 2025, the Trump administration threatened to revoke the nonprofit status of Harvard University after its leaders resisted numerous demands, including changes to its leadership and admissions policies.

Nonprofit news organizations have also faced pressure from the Trump administration. Several public media outlets are planning to shut down or reduce their operations following the Corporation for Public Broadcasting’s loss of government funding in 2025. It’s part of what’s widely seen as the administration’s attempt to control news media, a campaign that has also led to defamation lawsuits, a leadership shakeup at CBS News, and the Federal Communications Commission’s deregulation efforts.

So far, Harvard’s nonprofit status remains intact, and legal experts say it’s likely to stay that way. Still, at a time when many local news nonprofits are struggling to keep the lights on, I can understand why they might choose to tread lightly.

We created health guidelines for fighting loneliness – here’s what we recommend

Social isolation kills. It increases your risk of death by 30% — roughly the same as smoking cigarettes and much worse than factors such as obesity and sedentary living.

Americans are living through what researchers call a friendship recession, spending less time with friends than at any point in recent history.

In 2023, the U.S. Surgeon General declared loneliness an epidemic. Deaths from factors like suicide, addiction and alcoholism, referred to as deaths of despair, continue climbing.

While doctors routinely check patients’ blood pressure and ask about exercise habits, they rarely assess social health.

Public health guidelines urge Americans to eat their vegetables, exercise for 150 minutes weekly, sleep seven to nine hours nightly and drink less than one or two alcoholic beverages per day. But few public health bodies have addressed social connection — until now.

As scholars who focus on public policy and social determinants of health and well-being, we are part of an international team of more than 100 experts who undertook the first systematic effort to develop evidence-based guidelines for social connection.

These guidelines, which are now publicly available, aim to do more than offer advice. Elements of them are already being embedded into policies in the Netherlands and the U.K.

Our hope is that the guidelines can elevate the importance of social connection to the same level as basic public health practices such as exercising, not smoking and relying on a designated driver when you go out drinking with friends.

Social isolation increases people’s risk of death dramatically – about as much as smoking does.

The value of guidelines

Research has shown for decades that social connection is crucial for good health. The World Health Organization’s constitution, adopted in 1946, defines health as “complete physical, mental and social well-being.”

Codifying different dimensions of health into evidence-based guidelines matters because guidelines allow people to put recommendations into action. Nutrition labels help people understand what they’re eating. Exercise recommendations help people know how much movement protects their health. Blood pressure cutoffs tell both patients and clinicians when it’s time to intervene.

Guidelines also shape systems in ways people feel every day. Exercise guidelines, for example, helped motivate cities to invest in walkable streets and bike lanes, workplaces to design wellness programs, and schools to include physical activity in curricula.

Social health guidelines can play a similar role.

Standardized metrics for social well-being can help health care providers identify when someone is socially isolated, enable employers to design workplaces that foster connection, and give schools and cities clearer targets for building socially supportive environments.

They also lay the groundwork for “social prescriptions” — structured ways to connect people with community programs or group activities — which some health care systems are already beginning to test.

The science of connection

Beginning in the summer of 2023, our team spent more than two years developing a set of international guidelines for social health by drawing on more than 40 plain-language evidence summaries, numerous case studies, conversations with marginalized communities, and extensive consultation with global experts.

What we found highlights several foundational principles of social well-being.

First, there are no universal rules for social health. There is no magic number of friends or ideal number of weekly social hours. Social needs vary widely. Both introverts and extroverts need connection, but they meet that need differently. A new parent’s social world is completely unlike a retiree’s. And quality trumps quantity: One meaningful conversation can be more nourishing than a dozen quick exchanges.

Second, technology is not the villain it’s often made out to be. Passive scrolling can harm well-being, but active, intentional use can strengthen bonds — whether through video calls with distant family, group chats that sustain friendships or apps that help neighbors organize local meetups. The key is using technology to facilitate real connection rather than replace it.

Third, relationships are shaped as much by systems as by individuals. Social health isn’t just about personal effort. It emerges from local environments that make connection possible. Research shows that investments in social infrastructure – the places and spaces where we connect, such as libraries, parks and cafes – measurably improve well-being. And communities that have denser concentrations of such spaces have better health outcomes after disasters.

Finally, diverse networks matter. Strong social health includes both close relationships and “weak ties” — acquaintances, neighbors, local business staff and others you see in passing. These lighter-touch interactions offer meaningful benefits: the barista who remembers your order, a colleague you exchange a few words with, a fellow dog walker along your route.

Studies show that weak ties provide novel information, unexpected opportunities and a broader sense of belonging that close friends alone can’t provide. A mix of ties — deep and shallow — forms the basis of a socially healthy life.

From research to reality

Forward-thinking institutions are already experimenting with principles that underpin our guidelines.

Some workplaces now assess social health when making decisions about policies such as remote work or office layout, recognizing that communication norms and physical design shape how employees connect. Schools are teaching emotional intelligence and friendship skills as core curriculum, not extras. Cities are investing in social infrastructure — community centers, shared public spaces and plazas — that naturally bring people together.

On a personal level, the guidelines suggest a few simple shifts:

  • Prioritize face-to-face time. Even short, in-person interactions boost mood, reduce stress and build trust.

  • Use technology actively, not passively. Reach out to someone, schedule a video call or use apps to create opportunities for connection — not just to scroll.

  • Treat solitude as restoration, not failure. Healthy social lives include both meaningful interaction and the downtime needed to recharge.

  • Build routines that create natural interaction. Walk the same route daily, become a regular at neighborhood spots or join recurring community activities to create predictable opportunities for connection.

  • And most importantly, take initiative. In a culture that treats socializing as a luxury, prioritizing connection is quietly radical.

Mid-Atlantic mushroom foragers collect 160 species for food, medicine, art and science

Like many mushroom harvesters, I got interested in foraging for fungi during the COVID-19 pandemic.

I had been preparing for a summer of field work studying foraged desert plants in a remote part of Australia when the pandemic hit, and my travel plans were abruptly frozen. It was March, right before morel mushrooms emerge in central Pennsylvania.

I wasn’t doing a lot other than going on long hikes and taking classes remotely at Penn State for my doctoral degree in ecology and anthropology. One of the classes was an agroforestry class with Eric Burkhart. We studied how agriculture and forests benefit people and the environment.

These two things eventually led to a yearslong project on mushroom harvesting in our region.

Why people forage

Foragers have been harvesting wild mushrooms in what is now Pennsylvania and the rest of the U.S. mid-Atlantic region for generations, but the extent and specifics of the practice in the region had not been formally studied.

In 2021, Burkhart and I decided that we wanted to better understand the variety of wild mushroom species that Pennsylvania harvesters collect and what they use them for.

We conducted a series of surveys in 2022 and 2023 that revealed a wide variety of fungi are foraged in the region – though morels, chicken of the woods and chanterelles are most common. We also learned that harvesters use the mushrooms primarily for food and medicinal purposes, and that foragers create communities that share knowledge. These community based projects often use social media tools as a way for mushroom harvesters to share pictures, notes and even the results of DNA sequences.

Our findings were published in the journal Economic Botany in October 2025.

160 species

Having spent a year building connections with local mushroom harvesters, starting in central Pennsylvania, including members of mushroom clubs and mycological associations, we recruited a diverse group of harvesters from around the mid-Atlantic. We also used mushroom festivals, social media and word of mouth to get the word out.

We asked harvesters about their favorite mushrooms, common harvesting practices, resources they used while harvesting and any sustainability practices.

Over 800 harvesters responded to the survey and reported that, collectively, they foraged 160 species of wild mushrooms. Morels and chicken of the woods were the two most popular, as each were reported by 13% of respondents. About 10% of respondents reported collecting chanterelles. Other popular species were hen of the woods, oysters, lion’s mane, black trumpet, honey mushroom, turkey tail, bolete, reishi, puffball, chaga, shrimp of the woods and Dryad’s saddle, which is also known as the pheasant’s back mushroom.

Harvesters reported a variety of reasons for collecting mushrooms. Many collected morels and chanterelle to eat, and species such as turkey tail, reishi and chaga for medicinal purposes. Art was another common reason cited for foraging, with photography being the most popular use, followed by using mushrooms to create natural dyes and pigments.

Other survey respondents said they foraged to feel more connected to nature. And while there is a thriving commercial wild mushroom industry in the region, we found that only a small minority of harvesters sell their mushrooms. Most people reported giving their mushrooms to friends, neighbors and family.

Citizen science

We also wanted to better understand which resources mushroom harvesters turn to in order to learn more about this hobby. We asked all the harvesters what they used as a resource when they were first learning to hunt for mushrooms. A quarter of new harvesters said they used the “the internet,” followed by “family,” at 24%, and then guide books, at 20%.

Based on the survey responses, we also learned that mushroom-identification phone apps are growing in popularity, especially among new harvesters. For example, a commonly used app called iNaturalist allows harvesters to upload a few pictures of their find – one of the mushroom in its habitat, another of the underside of the cap, and a third of the entire mushroom. From there, other community members can comment and help with identification.

Harvesters also use these apps to contribute to community science projects that document biodiversity.

Some mushrooms are poisonous if eaten, which is part of why harvesters are so careful with their identification. When learning a new mushroom species, it’s important to look into multiple sources to make sure what you’re harvesting is safe to eat.

With more harvesters documenting their findings on social media and sharing information about fungal biodiversity in the region, there is much to glean and learn about the diverse world of mushrooms in the mid-Atlantic. We believe that deeper collaboration between community groups and researchers at universities and other institutions is an opportunity for scientific growth within the field of mycology. This collaboration can support long-term tracking of fungal populations and any impact that harvesters might have on them.

How will the universe end? – Iez M., age 9, Rochester, New York


Whether the universe will “end” at all is not certain, but all evidence suggests it will continue being humanity’s cosmic home for a very, very long time.

The universe – all of space and time, and all matter and energy – began about 14 billion years ago in a rapid expansion called the Big Bang, but since then it has been in a state of continuous change. First, it was full of a diffuse gas of the particles that now make up atoms: protons, neutrons and electrons. Then, that gas collapsed into stars and galaxies.

Our understanding of the future of the universe is informed by the objects and processes we observe today. As an astrophysicist, I observe objects like distant galaxies, which lets me study how stars and galaxies change over time. By doing so, I develop theories that predict how the universe will change in the future.

Predicting the future by studying the past?

Predicting the future of the universe by extending what we see today is extrapolation. It’s risky, because something unexpected could happen.

Interpolation – connecting the dots within a dataset – is much safer. Imagine you have a picture of yourself when you were 5 years old, and then another when you were 7 years old. Someone could probably guess what you looked like when you were 6. That’s interpolation.

A picture explaining interpolation vs extrapolation using pictures of the author at different ages
Using a picture of the author when he was 5 years old and 7 years old, you could interpolate what he looked like when he was 6 years old, but you couldn’t predict what he would look like at 29.
Stephen DiKerby

Maybe they could extrapolate from the two pictures to what you’d look like when you are 8 or 9 years old, but no one can accurately predict too far into the future. Maybe in a few years you get glasses or suddenly get really tall.

Scientists can predict what the universe will probably look like a few billion years into the future by extrapolating how stars and galaxies change over time, but eventually things could get weird. The universe and the stuff within might once again change, like it has in the past.

How will stars change in the future?

Good news: The Sun, our medium-sized yellow star, is going to continue shining for billions of years. It’s about halfway through its 10 billion-year lifetime. The lifetime of a star depends on its size. Big, hot, blue stars live shorter lives, while tiny, cool, red stars live for much longer.

Today, some galaxies are still producing new stars, but others have depleted their star-forming gas. When a galaxy stops forming stars, the blue stars quickly go “supernova” and disappear, exploding after only a few million years. Then, billions of years later, the yellow stars like the Sun eject their outer layers into a nebula, leaving only the red stars puttering along. Eventually, all galaxies throughout the universe will stop producing new stars, and the starlight filling the universe will gradually redden and dim.

Red dwarf stars are the longest-lived type of stars. Once star formation shuts down throughout the universe, eventually only red stars will be left, gradually fading away over trillions of years.
NASA/ESA/STScI/G. Bacon

In trillions of years – hundreds of times longer than the universe’s current age – these red stars will also fade away into darkness. But until then, there will be lots of stars providing light and warmth.

How will galaxies change in the future?

Think of building a sand castle on the beach. Each bucket of sand makes the castle bigger and bigger. Galaxies grow over time in a similar way by eating up smaller galaxies. These galactic mergers will continue into the future.

In galaxy clusters, hundreds of galaxies fall inward toward their shared center, often resulting in messy collisions. In these mergers, spiral galaxies, which are orderly disks, combine in chaotic ways into disordered blob-shaped clouds of stars. Think of how easy it is to turn a well-constructed sand castle into a big mess by kicking it over.

For this reason, the universe over time will have fewer spiral galaxies and more elliptical galaxies because the spiral galaxies combine into elliptical galaxies.

The Milky Way galaxy and the neighboring Andromeda galaxy might combine in this way in a few billion years. Don’t worry: The stars in each galaxy would whiz past each other totally unharmed, and future stargazers would get a fantastic view of the two galaxies merging.

How will the universe itself change in the future?

The Big Bang kick-started an expansion that probably will continue in the future. The gravity of all the stuff in the universe – stars, galaxies, gas, dark matter – pulls inward and slows down the expansion, and some theories suggest that the universe’s expansion will coast along or slow to a halt.

However, some evidence suggests that some unknown force is starting to exert a repulsive force, causing expansion to speed up. Scientists call this outward force dark energy, but very little is known about it. Like raisins in a baking cookie, galaxies will zoom away from each other faster and faster. If this continues into the future, other galaxies might be too far apart to observe from the Milky Way.

A simulated view of the night sky from a planet in a huge elliptical galaxy
After star formation shuts down and galaxies merge into huge ellipticals, the expansion of the universe might mean that other galaxies are impossible to observe. For trillions of years, this might be the view of the unchanging night sky: a single red elliptical galaxy.
NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger

To summarize the best current prediction of the future: Star formation will shut down, so galaxies will be full of old, red, dim stars gradually cooling into darkness. Each group or cluster of galaxies will merge into a single, massive, elliptical galaxy. The accelerated expansion of the universe will make it impossible to observe other galaxies beyond the local group.

This scenario eventually winds down into a dark eternity, lasting trillions of years. New data might come to light that changes this story, and the next stage in the universe’s history might be something totally different and unexpectedly beautiful. Depending on how you look at it, the universe might not have an “end,” after all. Even if what exists is very different from how the universe is now, it’s hard to envision a distant future where the universe is entirely gone.

How does this scenario make you feel? It sometimes makes me feel wistful, which is a type of sadness, but then I remember we live at a very exciting time in the story of the universe: right at the start, in an era full of exciting stars and galaxies to observe! The cosmos can support human society and curiosity for billions of years into the future, so there’s lots of time to keep exploring and searching for answers.

AI is making spacecraft propulsion more efficient – and could even lead to nuclear-powered rockets

Propulsion technology helps rockets get off the ground. Joel Kowsky/NASA via AP

Every year, companies and space agencies launch hundreds of rockets into space – and that number is set to grow dramatically with ambitious missions to the Moon, Mars and beyond. But these dreams hinge on one critical challenge: propulsion – the methods used to push rockets and spacecraft forward.

To make interplanetary travel faster, safer and more efficient, scientists need breakthroughs in propulsion technology. Artificial intelligence is one type of technology that has begun to provide some of these necessary breakthroughs.

We’re a team of engineers and graduate students who are studying how AI in general, and a subset of AI called machine learning in particular, can transform spacecraft propulsion. From optimizing nuclear thermal engines to managing complex plasma confinement in fusion systems, AI is reshaping propulsion design and operations. It is quickly becoming an indispensable partner in humankind’s journey to the stars.

Machine learning and reinforcement learning

Machine learning is a branch of AI that identifies patterns in data that it has not explicitly been trained on. It is a vast field with its own branches, with a lot of applications. Each branch emulates intelligence in different ways: by recognizing patterns, parsing and generating language, or learning from experience. This last subset in particular, commonly known as reinforcement learning, teaches machines to perform their tasks by rating their performance, enabling them to continuously improve through experience.

As a simple example, imagine a chess player. The player does not calculate every move but rather recognizes patterns from playing a thousand matches. Reinforcement learning creates similar intuitive expertise in machines and systems, but at a computational speed and scale impossible for humans. It learns through experiences and iterations by observing its environment. These observations allows the machine to correctly interpret each outcome and deploy the best strategies for the system to reach its goal.

Reinforcement learning can improve human understanding of deeply complex systems – those that challenge the limits of human intuition. It can help determine the most efficient trajectory for a spacecraft heading anywhere in space, and it does so by optimizing the propulsion necessary to send the craft there. It can also potentially design better propulsion systems, from selecting the best materials to coming up with configurations that transfer heat between parts in the engine more efficiently.

In reinforcement learning, you can train an AI model to complete tasks that are too complex for humans to complete themselves.

Reinforcement learning for propulsion systems

In regard to space propulsion, reinforcement learning generally falls into two categories: those that assist during the design phase – when engineers define mission needs and system capabilities – and those that support real-time operation once the spacecraft is in flight.

Among the most exotic and promising propulsion concepts is nuclear propulsion, which harnesses the same forces that power atomic bombs and fuel the Sun: nuclear fission and nuclear fusion.

Fission works by splitting heavy atoms such as uranium or plutonium to release energy – a principle used in most terrestrial nuclear reactors. Fusion, on the other hand, merges lighter atoms such as hydrogen to produce even more energy, though it requires far more extreme conditions to initiate.

Fission is a more mature technology that has been tested in some space propulsion prototypes. It has even been used in space in the form of radioisotope thermoelectric generators, like those that powered the Voyager probes. But fusion remains a tantalizing frontier.

Nuclear thermal propulsion could one day take spacecraft to Mars and beyond at a lower cost than that of simply burning fuel. It would get a craft there faster than electric propulsion, which uses a heated gas made of charged particles called plasma.

Unlike these systems, nuclear propulsion relies on heat generated from atomic reactions. That heat is transferred to a propellant, typically hydrogen, which expands and exits through a nozzle to produce thrust and shoot the craft forward.

So how can reinforcement learning help engineers develop and operate these powerful technologies? Let’s begin with design.

Reinforcement learning’s role in design

Early nuclear thermal propulsion designs from the 1960s, such as those in NASA’s NERVA program, used solid uranium fuel molded into prism-shaped blocks. Since then, engineers have explored alternative configurations – from beds of ceramic pebbles to grooved rings with intricate channels.

NASA/Wikipedia

Why has there been so much experimentation? Because the more efficiently a reactor can transfer heat from the fuel to the hydrogen, the more thrust it generates.

This area is where reinforcement learning has proved to be essential. Optimizing the geometry and heat flow between fuel and propellant is a complex problem, involving countless variables – from the material properties to the amount of hydrogen that flows across the reactor at any given moment. Reinforcement learning can analyze these design variations and identify configurations that maximize heat transfer. Imagine it as a smart thermostat but for a rocket engine – one you definitely don’t want to stand too close to, given the extreme temperatures involved.

Reinforcement learning and fusion technology

Reinforcement learning also plays a key role in developing nuclear fusion technology. Large-scale experiments such as the JT-60SA tokamak in Japan are pushing the boundaries of fusion energy, but their massive size makes them impractical for spaceflight. That’s why researchers are exploring compact designs such as polywells. These exotic devices look like hollow cubes, about a few inches across, and they confine plasma in magnetic fields to create the conditions necessary for fusion.

Controlling magnetic fields within a polywell is no small feat. The magnetic fields must be strong enough to keep hydrogen atoms bouncing around until they fuse – a process that demands immense energy to start but can become self-sustaining once underway. Overcoming this challenge is necessary for scaling this technology for nuclear thermal propulsion.

Reinforcement learning and energy generation

However, reinforcement learning’s role doesn’t end with design. It can help manage fuel consumption – a critical task for missions that must adapt on the fly. In today’s space industry, there’s growing interest in spacecraft that can serve different roles depending on the mission’s needs and how they adapt to priority changes through time.

Military applications, for instance, must respond rapidly to shifting geopolitical scenarios. An example of a technology adapted to fast changes is Lockheed Martin’s LM400 satellite, which has varied capabilities such as missile warning or remote sensing.

But this flexibility introduces uncertainty. How much fuel will a mission require? And when will it need it? Reinforcement learning can help with these calculations.

From bicycles to rockets, learning through experience – whether human or machine – is shaping the future of space exploration. As scientists push the boundaries of propulsion and intelligence, AI is playing a growing role in space travel. It may help scientists explore within and beyond our solar system and open the gates for new discoveries.

Nick Fuentes is a master of exploiting the current social media opportunities for extremism

Source: The Conversation – USA – By Alex McPhee-Browne, PhD student studying the American and global far right, University of Cambridge

When Tucker Carlson hosted Nick Fuentes on his show last month, the response followed a familiar script. Critics condemned the platforming of a white nationalist. Defenders invoked free speech. Social media erupted.

“We’ve had some great interviews with Tucker Carlson, but you can’t tell him who to interview,” President Donald Trump said on Nov. 17, 2025. “Ultimately, people have to decide.”

Fuentes is a 27-year-old livestreamer with openly antisemitic views. He has called Adolf Hitler both “awesome” and “right.” But he has become impossible for the Republican Party to banish, despite repeated attempts by some party leaders.

This dynamic reveals how fringe ideologies operate differently today compared to the mid-20th century, when institutional gatekeepers – political parties, law enforcement, the media – could more effectively contain extremist movements.

And through their 21st-century methods of communication and operation, Nick Fuentes and his followers – the “Groypers” – have managed to get what their 20th-century predecessors could not: widespread awareness and political influence.

Atlanta, 1940: Brazen but brief fascist group

As a historian of the American far right, I have spent years examining how fascist movements adapted to the conditions of postwar America. The trajectory from the 1940s until today shows a fundamental shift: from defined organizational structures that could be dismantled to diffuse cultural movements that spread through social media.

Let me offer an example.

In 1946, barely a year after Hitler’s defeat, young men in khaki shirts marched through Atlanta, Georgia, performing Nazi salutes and promising racial vengeance.

Led by Homer Loomis Jr. – a Princeton dropout who called Hitler’s manifesto “Mein Kampf” his “bible” – this group, known as the Columbians, offered Atlanta a glimpse of explicit fascism. They conducted armed patrols, held uniformed drills and even drew up blueprints for blowing up City Hall.

Their brazenness, however, was matched by their brevity. Ten months after forming, Atlanta authorities revoked their charter and jailed the ringleaders.

The swift suppression seemed to prove that explicit fascism had no future in postwar America. And for decades that held true. Open Nazi sympathizers remained marginal, their organizations small and easily ostracized.

In the 1970s, when a group of American Nazis planned to march in Skokie, Illinois, a predominantly Jewish suburb of Chicago, the event was most notable for the counterprotests it triggered.

Mainstreaming fascism

But the Columbians’ failure, it turned out, was organizational, not ideological. The government could revoke a charter and convict leaders. They could not repress a mood.

In the digital age, Fuentes represents that mood as a diffuse sensibility rather than a structured organization. Where the Columbians wore uniforms that advertised their fascist allegiance, Fuentes wears suits and frames his worldview in the rhetoric of “America First.”

The difference is strategic. In a 2019 livestream, Fuentes explained his approach openly: “Bit by bit we start to break down these walls … and then one day, we become the mainstream.”

This packaging marks a deliberate shift. Fuentes treats plausible deniability – of fascism, of antisemitism – not as a weakness but as a central feature. The content of his message remains extreme, but the ironic wrapping enables something the Columbians never achieved – cultural saturation.

Fuentes’s followers, Groypers, have in turn mastered this diffusion strategy.

For many conservatives under 40, exposure to Groyper-style content isn’t in meetings. They absorb it through social media feeds, Discord servers and group chats. A tone of grievance and ironic provocation becomes prominent background noise, moving the marginal toward the mainstream. A generation raised on anti-woke content, 4chan and transgressive memes now shapes the neofascist movement’s tone.

At the same time, institutional authority has in many ways effectively collapsed. The Columbians faced united opposition from media, prosecutors and politicians. Those gatekeepers no longer control conservatism or the white nationalists who are adjacent to it.

Achieving what predecessors could not

The Carlson-Fuentes interview has instead exposed a rift within MAGA circles.

Several board members of the Heritage Foundation, a conservative think tank with deep ties to the Trump administration, have resigned over the controversy, including one this week.

They were angered that Kevin Roberts, the foundation’s president, released a video defending the interview. Roberts has apologized for some of its contents but not retracted it.

Republicans aren’t all in agreement about whether Groypers represent a threat or an important constituency. Members of Congress have given speeches at Fuentes’ conferences; Trump dined with him at Mar-a-Lago in 2022.

Last year, JD Vance, now the vice president, called Fuentes a “total loser.” Fuentes attempted, without success, to mobilize Groypers against Trump in 2024 and called the president a “scam artist” earlier this year for failing to release the files in the Jeffrey Epstein case.

Yet the broader Groyperfication of conservative youth culture proceeds apace. Trump reversed his stance on the Epstein files. In defending Carlson’s interview with Fuentes, Trump said, “I don’t know much about him.”

Trump said roughly the same thing when he sat down to dinner with Fuentes at Mar-a-Lago in November 2022. Still, that event showed that the Groypers, now six years into their existence, have achieved what their predecessors could not: genuine cultural penetration and political influence.

The old remedies no longer function. Authorities cannot ban an atmosphere or revoke the charter of a meme. Social media platforms designed to maximize engagement often maximize anger. Fuentes and imitators exploit this frustration.

They remain controversial, and the Groypers’ lack of formal institutions could mean they will at some point fade like other far-right youth movements. Trump’s eventual exit from politics may also deprive them of a central reference point.

But they might represent something new: a post-organizational extremism uniquely adapted to digital life.

The Columbians once promised to control Atlanta in six months and America in 10 years. They lasted 10 months. The Groypers have already long outlasted them. That endurance signals a new, far more successful approach.

What Robert F. Kennedy Jr. didn’t tell you about ‘Operation Northwoods,’ the false flag operation he loves to denounce

Something’s missing from Robert F. Kennedy Jr.’s accounts of “Operation Northwoods.” Something that explains the origins of this menu of false flag operations – pretexts for war with Cuba – drafted by the Pentagon in March 1962.

Something about his father.

Most people remember Robert F. Kennedy as President John F. Kennedy’s closest confidant, campaign manager and attorney general, the tough but idealistic younger brother who helped him through the Cuban missile crisis and later waged an antiwar campaign for president, before becoming the second Kennedy brother slain by an assassin.

During Robert F. Kennedy Jr.’s political rise to his current position as Secretary of Health and Human Services, he capitalized on the story of “Operation Northwoods,” giving his version of it in speeches, interviews, and two separate books.

Kennedy Jr. pinned the blame for the pretexts solely on “the highest officials in the U.S. military,” accusing them of “lethal zealotry,” decrying “how badly the American military leadership had lost its moral bearings.”

To illustrate the point, he cited one pretext at length: “A ‘Remember the Maine’ incident could be arranged in several forms: We could blow up a U.S. ship in Guantánamo Bay and blame Cuba.”

In each of these accounts, Kennedy Jr. omitted the most important part of the “Operation Northwoods” story: his father’s role. I learned of that role from documents declassified by the JFK Assassination Records Review Board, in the Kennedy Library and in other archives while researching a book I’m writing, “Clandestine Camelot.”

Debacle with a chaser of deceit

In the first foreign policy memo he dictated, Attorney General Kennedy broached the idea of fabricating an attack on the U.S. naval base at Guantánamo Bay in Cuba, one of the spoils of the Spanish-American War.

It was April 19, 1961, and the Bay of Pigs invasion was in mid-collapse. Roughly 1,500 CIA-trained and -financed Cuban expatriates were mounting a doomed attempt to overthrow Fidel Castro, the Cuban revolutionary-turned-tyrant. Castro had the invaders pinned down on the beach under fire from Moscow-furnished MiG fighter jets.

It was then that the attorney general asked the president if they could get Central and South American nations “to take some action” to stop the flow of Russian arms to Cuba “if it was reported that one or two of Castro’s MiGs attacked Guantanamo Bay and the United States made noises like this was an act of war and that we might very well have to take armed action ourselves.”

Castro, of course, had not attacked the U.S. naval base. That would have meant war with America and the end of his regime.

President Kennedy didn’t act on his brother’s suggestion, but began including him regularly in foreign policymaking. Newspapers started calling RFK “the second most important man in the Western World.”

From subversion to military intervention

During the 1960 presidential campaign, JFK called Cuba a “Soviet satellite” and a “potential enemy missile or submarine base only 90 miles from our shores.” In November 1961, hoping to undo the Bay of Pigs failure, he created his own covert operation “to help Cuba overthrow the communist regime.” He put his brother Robert in charge of the secret program of subversion, code-named “Operation Mongoose.”

Fomenting revolution in Cuba faced an insurmountable obstacle: Castro was already powerful enough to crush any purely internal uprising.

CIA, State Department, and Defense Department officials agreed that the only way to overthrow Castro was a U.S. invasion.

Under Robert Kennedy’s leadership, the “Special Group (Augmented),” the interagency group JFK charged with overseeing Mongoose, proposed to change the covert operation’s goal from orchestrating subversion to justifying U.S. military intervention.

On March 5, 1962, the group asked Deputy Under Secretary of State for Political Affairs U. Alexis Johnson “to have a list prepared of various situations which would serve as a plausible pretext for intervention.” In the minutes of that meeting, someone crossed out “plausible pretext” and wrote “valid basis.”

The origin of ‘Operation Northwoods’

After the meeting, “in response to direction,” Mongoose operations chief Edward G. Lansdale asked the Joint Chiefs of Staff for “a brief but precise description of pretexts which the JCS believes desirable for direct military intervention.”

The Joint Chiefs of Staff responded by drafting the document now known as “Operation Northwoods.”

Fun fact: No one called it “Operation Northwoods” at the time.

“Northwoods” was just a code word the Joint Chiefs of Staff used on Mongoose documents. In the 21st century, however, historians mistook the code word for a code name and gave the pretexts their unhistorical handle. There was no “Operation Northwoods,” but that didn’t stop it from getting its own Wikipedia page.

The Special Group (Augmented) voted on March 13, 1962, to alter the Mongoose guidelines to state “that final success will require decisive U.S. military intervention.”

Three days later, the group briefed the president on the revised guidelines, including secret “plans for creating plausible pretexts to use force, with the pretexts either attacks on U.S. aircraft or a Cuban action in Latin America for which we would retaliate.”

President Kennedy said “bluntly” that they were not then able to make a decision on the use of military force.

But he did tell the group to “go ahead on the guidelines.” Since the revised guidelines said that Cubans “will be used to prepare for and justify this [U.S. military] intervention, and thereafter to facilitate and support it,” the revision transformed Mongoose into a secret program to furnish the president with a pretext to invade Cuba if he so chose.

Fortunately, he didn’t.

Apocalyptic advice

The last recorded time Robert Kennedy urged his brother to consider a false flag operation was on Oct. 16, 1962, the first day of the Cuban missile crisis.

The president’s secret White House recording system captured Robert Kennedy advising him to consider fabricating a pretext for U.S military intervention: “Can I say that one other thing is whether we should also think of whether there is some other way we can get involved in this, through Guantánamo Bay or something. Or whether there’s some ship that … you know, sink the Maine again or something.”

JFK ignored the suggestion. Taking it would have, in all likelihood, started a nuclear war.

This year marks the centennial of Robert Kennedy’s birth, the perfect occasion to stop scapegoating the military for his darkest deeds. In drafting pretexts for war, the Pentagon was complying with instructions it received through the command structure the president established for Operation Mongoose. Generals have little choice but to comply with such instructions unless and until Congress outlaws false flag operations.

Robert F. Kennedy Jr. wrote that the “Operation Northwoods memo should serve as a warning [to] the American people about the dangers of allowing the military to set goals or standards for our country.”

In reality, it reveals the dangers of letting someone like Robert F. Kennedy use the power of the U.S. government to deceive Americans about life-or-death matters.
