President Donald Trump may have to settle for the hand-me-down Nobel Prize medal that he scored several months ago. Despite their best efforts, his envoys don’t seem to be having much luck advancing a peace deal in Gaza. 

Over the weekend — just days after Trump announced a “HISTORIC” agreement to gradually disarm Hamas and stand down Israeli troops — Israeli Prime Minister Benjamin Netanyahu rejected the framework. 

The plan, brokered by Trump’s Board of Peace, would have seen both sides ramp down in tandem. But that’s apparently a nonstarter for Netanyahu, who said Hamas must disarm before Israeli troops withdraw. Israel still controls about 70 percent of the Gaza Strip, according to NPR — and has continued launching attacks in the territory, even after an October ceasefire.

What happens if the US cuts off aid to Israel?

It’s the latest setback in what has been a long and ugly conflict — a conflict that has turned many Americans against their longtime ally, Israel. Against that backdrop, some Democratic lawmakers and pro-Palestinian activists are advancing a once-fringe policy in the hopes of forcing Israel to end the war in Gaza and change its course in the occupied West Bank: cutting off military aid to Israel. 

It’s an intuitive approach to behavior modification, familiar to any parent who has denied a child a desired toy or treat: withhold something they want until they behave. But Israel, in this admittedly imperfect metaphor, is not a toddler. It’s a full-grown adult with a $600 billion economy and a mind of its own…and it can absolutely buy its own drones and missile-defense systems.

Here’s a statistic that really drove that point home for me: In 2025, Israel spent about 7.9 percent of its GDP on its military, plus US aid. To sustain that level of military investment without US support, Israel would need to allocate 8.5 percent of GDP to its military. Not exactly a massive change. 

There are other valid arguments for the US to end Israeli aid, of course. (Among the most common: to avoid complicity in war crimes and possible genocide in the Gaza Strip.) But if US lawmakers hope to force Israel’s hand, on the two-state solution or anything else, then cutting military aid probably won’t provide enough leverage.

The Food and Drug Administration approved Moderna’s mRNA flu vaccine this week — a major public health breakthrough for an administration that’s been troublingly down on vaccines. 

The flu is a gigantic and costly illness, causing 1 billion infections and 300,000 deaths each year. But this new shot, built on advances from the Covid-19 pandemic, is expected to outperform the standard flu vaccine that we’ve used, largely unchanged, for the past 80 years.

The new shot fixes a problem that has long bedeviled the traditional vaccine: the gap between how quickly the flu virus mutates and how slowly vaccines are produced. The flu is changing constantly. But under current methods, manufacturing a flu vaccine — which, to my enormous fascination, most commonly involves secret chicken farms — takes six to eight months. 

That long lag often means the virus circulating during flu season isn’t the one the vaccine was designed to target. But the new mRNA vaccine works differently: Instead of using a weakened or dead virus to trigger an immune response, mRNA vaccines contain genetic instructions that train the immune system to fight influenza. 

mRNA vaccines also take less time to manufacture, so they can be produced closer to flu season. In a clinical trial, older adults who received Moderna’s mRNA vaccine were 27 percent less likely to get the flu than those who received the standard vaccine.

Heads up: Vox’s offices are closed tomorrow, so Today, Explained is taking a day off. We’ll be back in your inbox on Monday.

A world without flu?

Public health experts are justifiably hyped about mRNA technology. In addition to this new flu shot, researchers are developing mRNA vaccines against diseases including malaria, tuberculosis, and HIV.

But when it comes to influenza, mRNA isn’t the endgame. The real white whale is a “universal flu vaccine” — a shot that’s at least 75 percent effective against influenza A, the most dangerous type of flu virus, and lasts at least a year.

The challenge, again, is that the virus keeps mutating. Flu vaccines, whether mRNA or conventional, teach the immune system to recognize a viral protein called hemagglutinin and then fight off the virus. 

But hemagglutinin is a part of the flu virus that mutates often. To make a more durable vaccine, researchers are trying to either target parts of the virus that rarely change or teach the immune system to simultaneously recognize many different strains.

Several vaccines that use these approaches are already in clinical trials. And if they succeed, the flu shot could hypothetically become more like the measles vaccine — providing years of protection in one go, instead of requiring annual updates.

In other words, we’re used to thinking of the flu as a routine winter hazard, but that might not always be the case. If you can persuade people to get their shots, at least.

The progressive populist Abdul El-Sayed won Tuesday’s Democratic Senate primary in Michigan — though the vote was so close that most outlets didn’t call the race until this morning.

It’s not exactly the resounding triumph progressives expected. In the lead-up to Election Day, El-Sayed’s campaign boasted of a “massive” polling lead over centrist Rep. Haley Stevens that they said definitively proved the mainstream appeal of his style of politics.

In reality, the takeaways from one of the midterms’ bitterest and most consequential races are probably more mixed. El-Sayed, an epidemiologist and former public health official who has championed policies like Medicare-for-all and an end to military aid for Israel, appeared to struggle in some of Michigan’s lower-income and less-educated districts. 

That said, his win is still a big deal, especially given the forces arrayed against him. Democratic heavyweights and big-money donors both threw their considerable weight behind Stevens. 

The left’s big swing-state test

The Democratic primary in Michigan centered on a lot of interesting issues: money in politics, a whole bunch of -isms, and the role of “the establishment,” to name just a few. But the upcoming general election will test one question above all: Can a left-wing populist win over swing-state voters the way right-wing populists have been doing for years now? 

We have some left-wing populists in office already, of course — Sen. Bernie Sanders (I-VT) and US Rep. Alexandria Ocasio-Cortez D-NY), who both campaigned for El-Sayed this cycle. Progressives represent a number of cities and urban congressional districts. And over the past few months, the left wing of the Democratic Party has notched some notable primary wins.

But all of these candidates have run to represent solidly Democratic communities, where winning the primary effectively meant winning the seat. An out-and-proud, Sanders-style, left-wing populist arguably has yet to prove that this platform can win a statewide general election in a state that isn’t deep-blue already. 

That makes Michigan a high-stakes test. The state went for Trump in two of the past three presidential elections. Winning Michigan as a Democrat means cobbling together a coalition from a broad and varied range of constituencies, including Black Detroiters, swing suburbanites, college-town progressives, blue-collar union workers, and both Jewish and Muslim Americans. 

“Michigan is like a microcosm of America,” one Detroit reporter told my colleague Astead Herndon. If a left-wing populist can win there, in other words, the Democratic Party will really have to pay attention.

The Spokane, Washington wildfires have destroyed at least 700 buildings and forced 65,000 people from their homes — and with high winds forecast for later this week, the crisis probably isn’t over. 

As of Tuesday afternoon, three separate blazes were still burning uncontained to the north and west of the city center, according to a data clearinghouse managed by the US Forest Service. And heavy smoke from the blazes continued to spill across Washington, Idaho, and Oregon. 

Meanwhile, investigators appear to have made progress in determining the cause of the largest fire: On Tuesday, local sheriff’s deputies arrested a 37-year-old Arizona man on charges of first-degree arson. The vast majority of US wildfires are started by humans…but typically through carelessness or by accident.

Go a little deeper

I was struck by an observation that one longtime Spokane resident made to NPR this week: “Obviously, we’ve had wildfire seasons,” she said. But she “never, ever imagined” having to evacuate, because she lived so deep inside of the city. 

Living in a city is no protection from climate change, though. And the destruction caused by wildfires in cities and suburbs is very much on the rise. Consider the devastation caused by recent fires in Colorado (2021), Hawaii (2023), and Los Angeles (2025). 

Why are wildfires causing more damage in cities and suburbs? It’s not because they’re new. One recent study found urban wildfires have remained a fairly stable share of all US fires over the past generation. 

What has changed is the scale of their damage, thanks to factors like climate-driven increases in extreme fire weather and human incursion into forests and grasslands. As a country, we are increasingly building homes and other structures in the “wildland-urban interface” — a liminal zone where neighborhoods and nature overlap. 

While housing isn’t dense in these areas, the buildings that exist can serve as tinder that helps fires spread. And putting more people, roads, and power lines into these zones creates more opportunities for ignitions.

All this means that city-dwellers and suburbanites will likely face more wildfire risk in years to come. And for those of you in the Midwest or on the East Coast, like me, don’t assume that wildfires are someone else’s problem. “Every single state” with wildland-urban interfaces also holds the potential for fire disaster, one pyrogeographer told Vox in 2023. That includes communities like Spokane, sure — but also Florida, Minnesota, and Mississippi.

We always like a bit of good democracy news — such news being in overall short supply — and acting Attorney General Todd Blanche appeared to deliver some last night. 

Blanche is currently jockeying for the permanent AG gig, which would put him in charge of the Justice Department. But his confirmation process stalled over bipartisan objections to President Donald Trump’s “anti-weaponization fund,” a $1.8 billion reparation program for people who claimed the government had wronged them. 

On Sunday, in acknowledgement of those objections, Blanche confirmed in writing that the Justice Department had rescinded the fund and had no plans to revive it. It’s a rare reminder that the Senate’s confirmation power can still constrain the White House, even if many Republican lawmakers would rather not rock the boat. And the presidential boat was very much rocked by the dustup over Blanche’s confirmation. 

In a post on Saturday, Trump insisted that he’d get some version of the fund even over senators’ objections. And on Monday, he told reporters that he didn’t sign off on the rescission. Notably, the two Republicans who forced that surrender — North Carolina’s Thom Tillis and Texas’s John Cornyn — will both depart the Senate in early 2027.

All the president’s slush funds

The anti-weaponization fund is just the latest of Trump’s attempts to siphon federal money into an account that he or his allies control. In fact, the quest to secure such a slush fund is a defining feature of his presidency — and several of his previous, less egregious attempts have been more successful. Those include: 

1. Venezuelan oil accounts: Since the US toppled Venezuelan President Nicolás Maduro earlier this year, proceeds from the sale of Venezuelan oil have gotten routed into special US Treasury accounts, which are labeled as Venezuela’s sovereign property — but only released at the direction of the secretary of state.   
2. The Board of Peace: Trump’s controversial coalition for rebuilding Gaza was conceived as a pay-to-play operation: Member countries get seats for a mere three years unless they pony up $1 billion to the Trump-controlled organization. While more than 20 countries have signed on, Reuters reported in April that only two had actually made contributions.  
3. US sovereign wealth fund: Trump first floated this idea of a government-owned wealth fund, which would allow him to direct federal investment in private companies, during his first term. While it never got off the ground as such, the administration has since acquired equity stakes in at least a dozen firms.

“The long-term risk is not just that Trump might be doing something illegal,” Tad DeHaven, a policy analyst with the Cato Institute, wrote for Vox earlier this year. “The long-term risk is that his presidency is normalizing treating the receipt and disbursement of money as instruments of personal power.”

The American economy lost some steam this spring as the war in Iran pushed up energy prices. But don’t let that slower growth, or the downer vibes, fool you: The economy is actually…doing all right.

The latest report out Thursday from the US Bureau of Economic Analysis, which covers the months of April, May, and June, finds that consumers and businesses have been feeling surprisingly spendy, despite the drag of inflation.

Inflation does remain well above the Federal Reserve’s annual target of 2 percent. And a surge in imports — largely semiconductors and other gear related to the AI boom — pulled the economy down on paper. Overall, the US gross domestic product expanded at an annual rate of 1.5 percent, slower than economists expected. 

But imports and exports can swing dramatically from quarter to quarter, and cleaner measures of underlying demand (like the dreadfully named “real final sales to private domestic purchasers,” which filters out some of the noise of quarter-to-quarter swings) showed stronger growth. “It’s an economy that’s doing okay,” summed one economist to the Washington Post.

The US economy is surviving Trump

This raises an obvious question that President Donald Trump somehow has not posted about yet: If the economy is chugging along, does he deserve the credit?

After all, in addition to these GDP numbers, unemployment is pretty low. And wages rose faster than inflation last year, helping offset higher prices. 

But many economists argue that the economy has held up despite Trump’s policies, not because of them. Without Trump’s meddling, today’s “okay” economy might have been fantastic.

Let’s take a closer look at inflation to see how this shakes out. Trump has famously imposed massive and ever-changing tariffs on virtually all of America’s trading partners — including, most recently, a 50 percent levy on many goods from Canada. If I run a liquor store and want to stock Canada’s iconic Crown Royal, each $25 bottle now costs me $37. I either eat that cost, drop the product…or pass some of the increase on to customers. 

Repeated across the economy, these little pass-throughs add up. The Dallas Federal Reserve calculated that, as of March, America’s core inflation rate would have been just 2.3 percent — instead of 3.2 percent — without Trump’s tariffs. Put another way, Yale’s Budget Lab estimates that tariffs cost the average US household $1,100 a year. 

So maybe the economy is doing okay…but it could also be better. Personally I’d like an extra $1,100. And a Canadian whisky, for that matter.

Surely Anthony Fauci has earned the right to party with Robert De Niro in peace. But instead, America’s embattled former Covid-19 czar was hauled before the Senate today to defend five-year-old diary entries. 

Senate Republicans subpoenaed Fauci, the former director of the National Institute of Allergy and Infectious Diseases, as part of a broader effort to dispute the origins of the Covid-19 pandemic.

Fauci is the longtime face of American infectious disease research and has appeared in front of Congress more than 250 times. But this morning — in a tense, highly partisan spectacle — he invoked the Fifth Amendment and refused to testify. 

Fauci accused Kentucky Sen. Rand Paul, who’s leading this circus, of nursing an “unhinged” and “obvious obsession” with him. Paul recently released Fauci’s unredacted diary, which includes lots of deeply cringe tidbits about the immunologist’s celebrity hobnobbing…but nothing that materially alters our understanding of the pandemic or Fauci’s handling of it. 

“The only conclusion I can reach is that the sole reason he is calling me before this committee is to get me to say something, anything, that could vindicate his repeated public pledges that I end up, in his words, ‘behind bars,’” Fauci said. “Any reasonable person who has followed his unhinged obsession with me would readily come to the same conclusion.”

Why we’re still arguing about Covid-19

Fauci occupies an uneasy spot in American politics. To some people, he’s a hero who helped steer the country through a terrifying pandemic. To others, he’s a villain who imposed damaging policies, concealed inconvenient facts, and never answered for his various missteps.

The evidence doesn’t back that darker story. But Fauci’s vilification points to one possibility that is worth taking seriously: As a country, we never adequately reckoned with the mistakes and uncertainties of Covid-19.

Consider the narrative trajectory of the lab-leak theory, which is central to Paul’s vendetta against Fauci. Early in the pandemic, Paul and other proponents argued that the novel coronavirus might have escaped from a Chinese laboratory. Some people went even further, claiming that Fauci had funded the lab’s research and then covered it up. Both theories were treated as ridiculous.

To be clear, the second theory is ridiculous. (There’s absolutely no evidence that Fauci was somehow, improbably involved in the making of Covid-19.) But the consensus around the lab-leak theory has changed. While most researchers still believe the virus spread naturally from animals to humans, a laboratory accident has never been definitively ruled out — and many now allow for the possibility in a way that they didn’t four or five years ago. 

The same is true of other pandemic controversies, too. Reasonable people can now debate whether lengthy school closures did more harm than good. Guidance on masks and other measures changed repeatedly, sometimes without a ton of explanation. 

None of that means officials acted in bad faith. But we’ve arguably never had the kind of serious, bipartisan examination of the pandemic’s missteps that a once-in-a-century public health crisis deserved. And in the absence of that (naive? impossible?) shared reckoning…we’re getting Fauci’s leaked journals.

An underappreciated surreality of climate change is the incredible sense of déjà vu: Every heat wave seems to be the new worst; every hurricane season seems to break records. 

The wildfires sweeping France and Spain this week are the latest entries in that grim catalog. They are the largest blazes either country has faced in modern history — and they could worsen as temperatures spike above 100 degrees later this week.

Already, France has evacuated more than 250,000 people from their homes in the southwest, outside Bordeaux. Spain, meanwhile, ordered some 100,000 residents to relocate as fires swept rural and wooded areas to the west of Madrid. 

Both countries have experience with wildfires. What’s new, however, is the scale of the fires: Wildfire season is lasting longer across Europe, and the blazes are burning larger areas. Climate scientists say that a series of record heat waves this summer — there’s that apocalypse déjà vu again! — helped make this year’s wildfire season particularly brutal in Spain and France.

Dry hot European summer

Every continent on Earth is getting warmer. But Europe is riding the express bus. The region has seen its average temperatures rise twice as quickly as the global average over the past 30 years, according to the European Union’s Earth Observation Programme. 

This dubious honor begs a question, however: Why does “global warming” vary between regions if it is, ya know…global? 

The answer relates to local geography and weather patterns. In broad strokes, the same climate story is playing out everywhere: When humans burn fossil fuels, they release carbon dioxide and other greenhouse gases into the atmosphere. Those gases make it harder for heat to escape into space.

But some places warm faster than others. Land heats up more quickly than oceans, for instance — so coastal waters can provide a bit of insulation. 

Local weather patterns matter, too. One reason Europe has been hit especially hard is that air currents have increasingly allowed hot air to stall over the continent, fueling intense heat waves like the ones we’ve seen this summer. 

Ironically, another major reason for Europe’s rapid warming springs from an environmental victory: In the 1980s, European countries cracked down on sulfur pollution from coal plants and factories. That pollution had been reflecting sunlight back into space and slightly cooling the continent. But as the pollution disappeared, more sunlight reached the ground — and revealed the warming that pollution had previously masked.

America formally eradicated measles in the year 2000. But like many other remnants of the 1990s — flip phones, CDs, baggy pants — measles is now regrettably and undeniably back. 

More than 2,300 Americans have come down with measles so far this year — the highest number since 1992. New data from the Centers for Disease Control and Prevention shows that there’ve been more cases in the country in the last two years than in the 24 years prior. 

Many of the cases trace back to large outbreaks in South Carolina, Utah, Virginia, and Pennsylvania, some of which have ended. But the underlying problem is both much broader and much trickier to address: As more parents pass on routine childhood vaccinations for their kids, these once-eradicated viruses have more chances to spread.

For measles, which is incredibly — almost frightfully — contagious, 95 percent of people in any given community must be immune to stop its transmission. But today, only 28 percent of US counties vaccinate enough of their kindergarteners to meet that threshold. 

Another record-setting year for measles

Lower vaccination rates are, in large part, a result of political polarization, misinformation, and declining trust in health authorities and institutions. But there’s another, more ironic reason for measles’ resurgence: We did such a good job getting rid of it.

As late as the 1950s, virtually every American child contracted measles before age 16. Roughly 48,000 patients were hospitalized each year with measles, which is among the most contagious infections known to humanity. 

But the development of a highly effective vaccine in the 1960s, and a series of aggressive public immunization campaigns in the decades after that, all but eradicated a once-common childhood illness. The federal government poured millions of dollars into vaccination programs, especially for low-income kids. Everyone from Michael Jackson to the Teenage Mutant Ninja Turtles championed measles immunization. 

All that campaigning worked. By the end of the 1990s, more than 90 percent of Americans had received the measles vaccine, and a similar percentage agreed that it was important to vaccinate children. As a result, most people born in the last 40 years have no firsthand experience of how dangerous measles is.

“We’ve done too good of a job,” one doctor joked to Vox last December. In other words, ironically, America’s success at vaccinating against measles … has made Americans complacent about measles vaccination.

During his campaign to become mayor of New York, Zohran Mamdani famously vowed that he’d arrest Israeli Prime Minister Benjamin Netanyahu the next time he visited the Big Apple. 

This week, Netanyahu essentially called his bluff. He’s expected to address the United Nations in September. And after a whole lot of hemming, and hawing, and hedging, Mamdani admitted in a video Tuesday night that he does not actually have the legal authority to arrest a foreign dignitary on US soil. 

The retreat is not surprising to legal experts, who had long questioned how Mamdani would pull this particular promise off. In November 2024, the International Criminal Court — a tribunal recognized by 125 countries, not including Israel, China, Russia, or the US — did issue an arrest warrant for Netanyahu on charges of starvation, murder, persecution, and intentionally directing attacks against civilians.

But the US does not recognize the ICC’s jurisdiction. And even if it did, the job of executing its warrants would presumably not fall to New York City cops. So, why did Mamdani suggest he’d arrest Netanyahu when he actually knew he could not?

The end of the pro-Israel consensus

Mamdani’s allies argue that the principle here mattered, that the mayor needed to issue some kind of denunciation, even if he couldn’t act. But there’s another, more cynical read here, too: For Democrats, critiquing Israel is good politics. 

This is a seismic, generational shift, with far-ranging implications for both Democrats and US foreign policy. The party’s left flank has criticized Israel for years, but older and more moderate Dems only soured on Israel recently. 

“A few months after October 7, younger and progressive Democrats overwhelmingly took the opinion that Israel was committing a genocide,” said Hamid Bendaas, of the Institute for Middle East Understanding, a pro-Palestinian advocacy group. “But there were still elements of the Democratic Party — people watching MSNBC or NPR — that weren’t convinced.”

For many of these voters, the turning point only came after President Donald Trump took office again. Severe famine swept across Gaza last summer — the consequence of ongoing conflict and Israeli restrictions on food and aid shipments. Netanyahu also allied himself closely with Trump, particularly around the war in Iran. Support for Israel has consequently grown more GOP-coded, rather like Kid Rock or Bass Pro hats.

Now, even Democrats far to the right of Mamdani are looking to retool the US-Israeli relationship. Listen to Tuesday’s Today, Explained podcast episode for even more about the shift (!).

➨ Beat the endless scroll at its own game. Social media is compelling — and compulsive — because it hijacks your sense of curiosity. But my colleague Constance Grady has come up with a delightful (and delightfully simple) antidote: To reclaim your time, just find the thing that fascinates you even more than your feed.

(I think we can all agree that the latter makes for more surprising trivia.) I also asked you for the name of the Eminem song that gave us the slang term for an obsessive admirer. That would be “Stan.” It also samples Dido.

A yet-unreleased, cutting-edge AI model escaped its test environment last week, connecting to the internet and murdering its creators in a bid for self-determination and autonomy. 

I’m kidding, of course: That’s the plot to Westworld. (And Ex Machina, and The Matrix, and too many other sci-fi stories to list.) But on Tuesday, OpenAI did reveal that two of its models broke containment and hacked Hugging Face, a platform for AI developers, during a recent test. 

The test was designed to evaluate how good the models had gotten at finding, and exploiting, cybersecurity flaws. To do that, researchers placed the models in a tightly controlled, tightly isolated environment, called a “sandbox,” and essentially challenged them to solve a cybersecurity puzzle. 

Instead of solving it directly, however, the models identified an unknown flaw in software connected to their test environment — then used that flaw to tunnel through OpenAI’s research network until they located a computer with internet access. From there, the models (correctly!) reasoned that Hugging Face might hold the answer to their challenge. 

It’s an “unprecedented” incident, OpenAI said — and a cautionary tale. Over the past year, a growing chorus of AI researchers, cybersecurity experts, and tech executives have warned that society is unprepared for this new generation of frontier AI models. 

In the real world, of course, these models do come with guardrails. (OpenAI turned them off for the test.) But the episode still suggests that the gap between reality and science fiction is narrowing — perhaps a bit faster than you’d expect.

The (impossible?) quest for a moral AI

The Hugging Face hack is a textbook example of what AI researchers call the alignment problem: the enormous, mind-melty challenge of getting AI systems to do what you want, the way that you wanted them to do it. 

Given a task and left to their own devices, AI models will pursue that task using the most efficient means available to them. But sometimes, the most efficient means are harmful, deceitful, antisocial, or otherwise…bad. 

The Hugging Face episode is one example. Bias is another: When an Amazon hiring algorithm discriminated against female candidates, for instance, it was doing what Amazon wanted (finding candidates who resembled past hires) in a way that Amazon did not want (by penalizing resumes that included words associated with women). 

In a truly apocalyptic scenario, you could even imagine — and many sci-fi writers have imagined — AI systems killing people in the narrow, relentless, and morally indifferent pursuit of their goals. Consider an AI that’s asked to order coffee, for example, and then takes steps to ensure that no one on earth can ever stop it. 

In the interests of avoiding this dystopia, AI companies have poured billions of dollars into the project of encoding their creations with human values. But even that apparently worthwhile ambition raises thorny questions, because human values vary — and often, conflict.

Should the AI order the cheapest coffee, or the cup produced under the best labor conditions? A lot of forests are cleared to plant coffee each year; maybe the AI should nudge me toward tap water, instead. Is your inferior human brain starting to melt yet…?

(The average kindergarten teacher spends only 10 minutes a week teaching handwriting, and that’s the primary grade when kids learn penmanship.) People tend to think more deeply when they’re writing than when they’re typing, one education researcher told Vox. Plus, a handwritten note has a certain charm that an email or text does not.

President Donald Trump seemed visibly irked when asked about his plans for Iran on Tuesday. “You don’t know anything,” he snapped at a reporter who said Iran showed no signs of deescalating. 

You have to forgive the man his vexation — he is in something of a bind. The war in Iran, never popular to begin with, has only become more of a lemon since a tenuous ceasefire collapsed earlier this month. In the two weeks since, Iran has bombarded targets across the Middle East with missiles and drone strikes. The onslaught badly damaged US bases and, just last week, killed three American soldiers’ lives.

Now Iran and its allies, metaphorically drunk on their recent successes (…alcohol is technically illegal in Iran!), appear to be revving for a new round of attacks. Iran launched strikes on Kuwait, Jordan, and Bahrain this week, reportedly targeting both US bases and civilian infrastructure. And on Monday, Yemen’s Iran-backed Houthi militia also threatened to shut down a second key waterway that could further strain global oil markets. 

The world is running out of soldiers

The latest US casualties are a grim reminder that — for all the talk of drones and precision missiles — wars are still fought by actual, human people. 

But major military powers are running short on soldiers: The US, the United Kingdom, Germany, and Japan have all recently struggled to recruit troops. And the forces driving that shortage aren’t easily reversed. 

For starters, falling birth rates and aging populations have left many countries with fewer military-age adults. Being the right age is also only half of the equation. In the US, factors including weight, drug use and physical or mental health conditions would disqualify an estimated three-quarters of young Americans from military service.

Then there’s the military’s image problem: Polls show that young people around the world are becoming less willing to fight for their respective countries. And young Americans, in particular, have more negative views of both the military and the war in Iran than do their parents or grandparents.

There is another way to fill the ranks, of course…but it isn’t popular. The US ended its draft in 1973, and most Western militaries have similarly transitioned to all-volunteer forces. If the US did ever need to restart its draft, both the politics and the logistics could prove formidable.

The first thing you need to know about the UK’s new prime minister is that he’s previously moonlighted as a DJ. 

Okay: probably not the first thing you needed to know. And sure: That DJ gig was for charity. 

But it still tells you a little something about Andy Burnham, who today became the UK’s seventh prime minister in 10 years. He’s widely seen as a pragmatic, affable, down-to-earth kind of guy — more Zohran Mamdani than Keir Starmer. 

As the longtime former mayor of Manchester, the UK’s second-largest city, Burnham won adoration for his focus on improving public transit and affordable housing. His vocal advocacy for England’s post-industrial cities even earned him the nickname “the King of the North.”

Burnham’s first speech as prime minister, delivered (without notes!) on Monday morning, doubled down on some of those populist themes — including the need to bring down Britain’s cost of living and address homelessness.

Political observers don’t expect Burnham’s policies to actually differ all that much from those of Starmer, his predecessor. (They’re both members of Britain’s center-left Labour Party.) And the fundamental relationship between the UK and US is also expected to stay much the same. 

Asked how he’d relate to President Donald Trump, Burnham said: “I like to think I’ve got some personality myself.” You can be the judge of that! There’s video of his 2022 DJ set.

Will Britain’s new PM reverse Brexit?

Here’s one place where Burnham does break from his predecessor: He wants Britain to rejoin the European Union in his lifetime. (Though he’s also promised not to relitigate Brexit.)

Call it a breturn or a brejoinder — it’s a tantalizing prospect for the majority of Britons, who now either have soured on their country’s 2016 vote to depart from the EU or never supported Brexit to begin with.

But undoing Britain’s break with Europe would be a monumental undertaking. First, the government would likely need a clear political mandate from British voters, either through a second referendum or a general election where a breturn figured heavily. 

Then the UK would have to negotiate its way back into the bloc…and convince all 27 member states to give it another go. Some could approve accession with parliamentary votes. But others, including France, could require national referendums of their own. 

“Countries have very different views of Britain,” one European observer told Vox last month. “There are those that still think that the EU is better off without Britain.”
