    White House may seek legally binding control over Columbia through consent decree – report

    The Trump administration is considering placing Columbia University under a consent decree, according to a report by the Wall Street Journal, a dramatic escalation in the federal government’s crackdown on the Ivy League institution.The university has already accepted a series of changes demanded by the administration as a pre-condition for restoring $400m in federal grants and contracts that the government suspended last month over allegations that the school failed to protect students from antisemitism on campus.A consent decree – a binding agreement approved by a federal judge – would be an extraordinary move by the Trump administration, which has threatened government funding as a way to force colleges and universities to comply with Donald Trump’s political objectives on a range of issues from campus protests to transgender women in sports and diversity and inclusion initiatives.As a party to the consent decree, Columbia would have to agree to enter it – and the Journal report states that it is unclear whether such a plan has been discussed by the university board.In a statement to the Guardian, the university did not directly address the report. “The University remains in active dialogue with the Federal Government to restore its critical research funding,” a spokesperson said.skip past newsletter promotionafter newsletter promotionAccording to the Journal, the proposal comes from the administration’s antisemitism taskforce, composed in part of justice department lawyers, who have reportedly expressed skepticism that Columbia was acting in “good faith”. If Columbia resists, the justice department would need to present its case for the agreement in court, a process that could drag on for years with the university risking its federal funding in the interim.Republicans and the Trump administration have sought to make an example of Columbia University, which was at the center of a student protest movement over Israel’s war in Gaza that broke out on campuses across the country. Last month, federal immigration authorities arrested Mahmoud Khalil, a Columbia graduate and prominent Palestinian activist who participated in campus protests. He remains in detention.During a cabinet meeting on Thursday, Trump pressed his education secretary, Linda McMahon, to elaborate on the department’s efforts to withhold federal funds from universities that were “not behaving”.“You’re holding back from $400 Columbia?” he asked McMahon. She nodded and named other schools, noting that the administration had frozen nearly $1bn in funding from Cornell.“We’re getting calls from the presidents of universities who really do want to come in and sit down and come in and sit down and have discussions,” she said. “We’re investigating them but in the meantime we’re holding back the grant fund money.” More

    US stocks fall again after rally following Trump’s shock retreat on tariffs

    US stocks fell again on Thursday after a historic rally following Donald Trump’s shock retreat on Wednesday on the hefty tariffs he had just imposed on dozens of countries.The falls came as the president blamed “transition problems” for the market reaction and the sell-off deepened after a White House clarification noted that total tariffs on China had been raised by 145% since Trump took office.Speaking at the White House, Trump said: “We think we’re in very good shape. We think we’re doing very well. Again there will be a transition cost, transition problems, but in the end it’s going to be a beautiful thing.”The sell-off comes as Democrats continue to react with anger over the sudden retreat that rattled markets, while Republicans praised Trump’s “art of the deal” in action, referencing Trump’s 1987 book.By the end of Thursday, the Dow was down 2.5% after soaring on Wednesday afternoon. The Nasdaq Composite was down more than 4%, after posting its biggest gain in more than two decades on Wednesday, and the S&P 500 down 3.4%.The market seems to be in a state of fatigue after a rollercoaster week. Stocks were even unresponsive to news on Thursday morning that the European Union announced it will suspend 25% retaliatory tariffs against US imports and new data showed inflation in the US cooled to 2.4% in March – both would typically be cause for optimism on Wall Street.On CNN, former US treasury secretary Janet Yellen called Trump’s economic policies the “worst self-inflicted wound” an administration had ever imposed on a “well-functioning economy”.Trump said in an abrupt announcement on Wednesday that he would be implementing a 90-day pause on his tariff plan, and that goods entering the US from most countries would now face a 10% blanket tariff until July, except for Chinese exports, which he said would face tariffs totaling 145% effective immediately – 125% in “reciprocal” tariffs plus 20% already imposed for China’s alleged role in the fentanyl crisis.Republican lawmakers praised the decision to pause the tariffs, with the House speaker, Mike Johnson, stating on social media: “Behold the ‘Art of the Deal.’ President Trump has created leverage, brought MANY countries to the table, and will deliver for American workers, American manufacturers, and America’s future!”Before the pause was announced, a small but growing number of Republican lawmakers and Trump supporters in the business world expressed concerns about the risks of the president’s tariff policy.By Wednesday afternoon, many were praising Trump for the rollback as part of a purported strategy.Bill Ackman, a billionaire hedge fund manager and Trump supporter who advocated for Trump to pause his trade war over the weekend, reacted to the announcement saying that “this was brilliantly executed by @realDonaldTrump. Textbook, Art of the Deal.”The benefit of Trump’s approach, Ackman claimed, “is that we now understand who are our preferred trading partners, and who the problems are. China has shown themselves to be a bad actor. Our counterparties also have a taste of what life is like if they don’t take down their trade barriers. This is the perfect set-up for trade negotiations over the next 90 days.”But some industry leaders criticized the administration’s back-and-forth and tariff decisions.On Thursday, Amazon’s CEO, Andy Jassy, said the company was still waiting to see the impact of the tariffs but warned third-party sellers may “pass that cost on” to consumers.“The effective tariff rate is actually HIGHER with the pause than it was as announced on April 2, due to the tariffs on China,” Diane Swonk, the chief economist of the professional services firm KPMG, wrote on social media. “There will be some diversion through connector countries. However, the effective tariff rate now peaks at 30.5% during the pause. That is worse than our worst case scenarios.”skip past newsletter promotionafter newsletter promotionWhile Republicans and White House officials praised Trump’s decisions, Democratic lawmakers such as Senator Chuck Schumer pushed back. Schumer told his supporters that “this chaos is all a game to Donald Trump”.“He thinks he’s playing Red Light, Green Light with the economy,” Schumer said. “But it is very real for American families.”Some Democrats have made accusations of possible market manipulation.“These constant gyrations in policy provide dangerous opportunities for insider trading,” Senator Adam Schiff said. “Who in the administration knew about Trump’s latest tariff flip-flop ahead of time? Did anyone buy or sell stocks, and profit at the public’s expense? I’m writing to the White House – the public has a right to know.”The New York representative Alexandria Ocasio-Cortez echoed similar concerns, urging any member of Congress who purchased stocks over the last two days to disclose that.“I’ve been hearing some interesting chatter on the floor,” she said. “Disclosure deadline is May 15th. We’re about to learn a few things. It’s time to ban insider trading in Congress.”The Democratic House whip, Katherine Clark, wrote: “Two hours before announcing his tariff pause, Trump told his paid Truth Social subscribers it was ‘a great time to buy’ on the stock market. Corruption is the name of their game.”The Nevada representative Steven Horsford questioned the US trade representative, Jamieson Greer, asking the representative during a committee hearing whether the climbdown was market manipulation.“How is this not market manipulation?” Horsford asked, to which Greer responded: “No.”“If it was always a plan, how is this not market manipulation?” Horsford asked again.“Tariffs are a tool, they can be used in the appropriate way to protect US jobs and small businesses, but that’s not what this does,” Horsford said. “So if it’s not market manipulation, what is it? Who’s benefiting? What billionaire just got richer?” More

    Mahmoud Khalil can be expelled for his beliefs alone, US government argues

    Facing a deadline from an immigration judge to turn over evidence for its attempted deportation of Columbia University activist Mahmoud Khalil, the federal government has instead submitted a brief memo, signed by the secretary of state, Marco Rubio, citing the Trump administration’s authority to expel noncitizens whose presence in the country damages US foreign policy interests.The two-page memo, which was obtained by the Associated Press, does not allege any criminal conduct by Khalil, a legal permanent US resident and graduate student who served as spokesperson for campus activists last year during large demonstrations against Israel’s treatment of Palestinians and the war in Gaza.Rather, Rubio wrote Khalil could be expelled for his beliefs.He said that while Khalil’s activities were “otherwise lawful”, letting him remain in the country would undermine “US policy to combat antisemitism around the world and in the United States, in addition to efforts to protect Jewish students from harassment and violence in the United States”.“Condoning antisemitic conduct and disruptive protests in the United States would severely undermine that significant foreign policy objective,” Rubio wrote in the undated memo.The submission was filed on Wednesday after Judge Jamee Comans ordered the government to produce its evidence against Khalil ahead of a hearing on Friday on whether it can continue detaining him during immigration proceedings.Attorneys for Khalil said the memo proved the Trump administration was “targeting Mahmoud’s free speech rights about Palestine”.The government is relying on a rarely used provision of a 1952 law giving the secretary of state broad powers to order the removal of immigrations deemed harmful to foreign policy. Khalil’s lawyers argue that law was never meant to go after constitutionally protected speech.Johnny Sinodis, one of Khalil’s immigration lawyers, said in a media briefing on Thursday that the memo doesn’t come close to meeting the evidentiary standard required under immigration law.“The Rubio memo is completely devoid of any factual recitation as to why exactly Mahmoud’s presence in the United States is adverse to a compelling US government interest,” he said.A Department of Homeland Security (DHS) spokesperson, Tricia McLaughlin, did not respond to questions about whether it had additional evidence against Khalil, writing in an emailed statement: “DHS did file evidence, but immigration court dockets are not available to the public.”Khalil, 30, was arrested on 8 March in New York and taken to a detention center in Louisiana. He is a Palestinian by ethnicity who was born in Syria. Khalil recently finished his coursework for a master’s degree at Columbia’s school of international affairs. He is married to an American citizen who is due to give birth this month.Khalil has adamantly rejected allegations of antisemitism, accusing the Trump administration in a letter sent from jail last month of “targeting me as part of a broader strategy to suppress dissent”.“Knowing fully that this moment transcends my individual circumstances,” he added, “I hope nonetheless to be free to witness the birth of my first-born child.”skip past newsletter promotionafter newsletter promotionThough Rubio’s memo references additional documents, including a “subject profile of Mahmoud Khalil” and letter from the Department Homeland Security, the government did not submit those documents to the immigration court, according to Khalil’s lawyers.The memo also calls for the deportation of a second lawful permanent resident, whose name was redacted in the filing.The Trump administration has pulled billions of dollars in government funding from universities and their affiliated hospital systems in recent weeks as part of what it says is a campaign against antisemitism on college campuses, but which critics say is a crackdown on free speech. To get the money back, the administration has been telling universities to punish protesters and make other changes.The US government has also been revoking the visas of international students who criticized Israel or accused it of mistreating Palestinians.At the time of Khalil’s arrest, McLaughlin, the DHS spokesperson, accused the activist of leading activities “aligned to Hamas”, referring to the militant group that attacked Israel on 7 October 2023.But the government has not produced any evidence linking Khalil to Hamas, and made no reference to the group in its most recent filing.Baher Azmy, the legal director of the Center for Constitutional Rights and a member of Khalil’s legal team, acknowledged the case’s high profile and its stakes.“If the secretary of state claims the power to arrest, detain and deport someone, including a lawful permanent resident, simply because that person dissents from US foreign policy, there are no limits. There’s no beginning and no end to that kind of executive power,” he said. More

    Sledgehammer-wielding Musk critics smash up Tesla in London art project

    Protective helmets were donned and sledgehammers wielded as Elon Musk critics vented their frustration at the Tesla boss and billionaire by smashing up a disused Tesla bound for the scrap heap.The public art project was organised by the social media campaign group Everyone Hates Elon. A 2014 Tesla Model S was provided by an anonymous donor “to create a debate about wealth inequality”, a spokesperson for the group said.The participants gathered at Hardess studios in south London on Thursday to take it in turns to swing at the car with sledgehammers and baseball bats. The destroyed electric vehicle, which retails for about £14,000, will be auctioned in the next few weeks, with all proceeds going to food bank charities.“We’re giving Londoners a chance to stand up to far-right hatred and billionaires and express how they feel about the current state of the world,” said the group. “Therapy is expensive, but this is free.”Talia Denisenko, a 32-year-old writer, wore a Ukrainian flag as she took a hammer to the car’s bonnet as Britney Spears’s Hit Me Baby One More Time blared from a speaker. “My family is Ukrainian and Elon Musk wants to keep us occupied,” she said. “Things feel very disempowering at the moment. This is a little bit of therapy.”Alice Rogers, a 24-year-old University of Cambridge researcher from Illinois, said: “Musk is acting in ways which violates our constitution. I’m very concerned by what I’m seeing – he’s gutting agencies and cutting USAID. This felt really cathartic. I’m not normally a smasher, but that felt really good.”View image in fullscreenEveryone Hates Elon, which garnered attention this year for distributing stickers with the slogan “Don’t buy a Swasticar”, said it had made clear that the stunt, called London vs Musk, should not be replicated outside the event.“This is a private event with a used Tesla that was destined for the scrapyard – it’s a supervised, controlled art piece and there are proper safety measures in place,” said a spokesperson. “We urge people not to damage other Teslas or any other cars.”The battery of the scrap car had been removed and recycled.“I’m just aghast at what I see going on in America at the moment,” said Lee Woods, a 45-year-old university lecturer who had travelled two hours from Hampshire for the event. “I think Musk is using his obscene wealth to promote the far right.”Musk, the world’s richest person, leads the Trump administration’s “department of government efficiency” (Doge), which the president tasked with drastically reducing US government jobs and cutting national debt.View image in fullscreenTesla’s shares dropped 13% in the first three months of 2025 – an indication of buyer backlash as a result of Musk’s rightwing politics. Protests calling for a boycott of the electric vehicle company have been taking place on both sides of the Atlantic in recent months, including a global day of action where hundreds of Tesla branches were targeted by protesters from the US group Tesla Takedown.“My opinion [on Musk] has changed hugely,” said Giles Pearson, 32, who dealt the first blow on Thursday. “Since buying Twitter he’s become seriously rightwing and alienated a lot of people by doing so. I would never normally do something like this … but I’ve always wanted to smash a car.”Tesla was approached for comment. More

    The Guardian view on the tariff war pause: the Trump trade shambles is not over | Editorial

    It was Donald Trump who blinked first. Never forget that. China is unlikely to overlook its importance. A week after launching an all-out global trade war, the US president paused significant parts of it for 90 days. Having insisted that he would stick with the random tariffs he imposed on most trading nations, Mr Trump suddenly decreed that he would reduce most of them to 10%. It was a major humiliation.Yet 10% is still a significant tariff to bear for nations exporting to the US. This is also only a pause until July, not a withdrawal, so the uncertainty remains. And huge tariffs still remain on China (now hiked to 145%), Canada and Mexico (both 25%), as well as on all US imports of steel, aluminium and cars (also 25%). Mr Trump is now substituting a US-world conflict with a US-China one. The two largest economies in the world – which between them have generated around half of global economic growth in the 21st century – are, in effect, no longer doing business with each other.Even so, this was a necessary step back from the cliff edge. It was enough to trigger a temporary bounceback on stock markets around the globe, though prices slipped back on Thursday and remain much lower than at the start of April. In the week since Mr Trump’s absurd “liberation day”, more than $6tn dollars of value was wiped from stocks on the S&P 500 index. It is a shameful outcome.Mr Trump claims he made the move because more than 75 nations had been willing to negotiate or “kiss my ass”. This is nonsense. He has got nothing out of the tariff war. He has not won. No one has negotiated. Mr Trump is making his usual efforts to claim yet another triumph. The plain truth is that he backed down because he was forced to.That Mr Trump can retreat is good news, as far as it goes. Overall, however, the past week has been an indictment of the president, his policies, his instincts and his behaviour. The pause should on no account be seen as proof that rational business can be done with him. For one thing, this week’s mayhem may easily kick off again as July nears. The White House has merely given itself more time to make some very big calls.Two things appear pivotal in the decision announced on Wednesday. The first was the overheating of the US bond market, subverting the established assumption that dollar bonds will always be a safe asset, and drawing the Federal Reserve to the threshold of intervention. A similar crisis doomed Liz Truss’s economic strategy in the UK in 2022, but the destructive potential of a US bond crisis is far greater. Mr Trump’s tariffs were threatening all-out recession.The second factor was some limited elite domestic pushback. Anxious senators appeared on Fox News (which the president watches) and pressed the case for dialling down. The head of JPMorgan Chase warned about recession. So did a handful of world leaders and some Trump cabinet members in telephone calls.These realities were a brake on Mr Trump this time. It is possible the trauma has left its mark and there will now be no repeat. But there is no case for confidence, let alone for accepting that this outcome had been schemed all along. Even Mr Trump admitted that Americans were “getting yippy”. They had every right to be. So did the markets, along with the rest of the world. Trust disappeared long ago, replaced now by uncertainty. There is no way that this is over. More

    US government has revoked more than 600 student visas, data shows

    More than 600 international students and recent graduates in the US have had their visas revoked or their legal status changed by the state department, according to data aggregated from around the country.The data, collected by Inside Higher Ed, shows that as of Thursday more than 100 colleges and universities have identified more than 600 cases of students whose immigration status was changed by the Trump administration. These institutions say that their students have lost their F-1 or J-1 student visas.Some of these cases were related to their activism and participation in student-led protests against the war in Gaza, and others were for “minor crimes”. Inside Higher Ed says that the majority of college officials say they’re unsure why the foreign-born students had their visas revoked or have yet to receive formal notification of the changes. Most have still not received any communications from immigration authorities.The compiled data set was based on public reports and direct correspondence, Inside Higher Ed says. The database, first published 8 April, will be consistently updated at least twice a day.Late last month, it was reported that the state department had revoked 300 or more student visas in the three weeks that its “Catch and Revoke” program was in operation.The initiative, newly launched by the state department, which says it is at least partly powered by artificial intelligence (AI), scrapes social media to find “foreign nationals who appear to support Hamas or other designated terror groups” and cancel their visas, according to reporting from Axios.The secretary of state, Marco Rubio, confirmed the scale of the March crackdown and referred to the student activists as “lunatics”. He told reporters during a visit to Guyana in South America when asked about the visa terminations: “Maybe more than 300 at this point” have lost their visas. “We do it every day, every time I find one of these lunatics.”It was increasingly clear that the abrupt visa cancellations are not limited to students who engage in pro-Palestinian activism. Students with minor non-criminal infractions, such as speeding tickets, were also targeted.The Guardian previously reported on an online data sheet created and updated by affected students that showed students from 50 universities reporting their visas were canceled around 4 April , with some tracing the cause to police citations or non-criminal offenses.Students at the University of Florida have planned a campus protest in support of Felipe Zapata Velázquez, 27, a Colombian student deported by the Trump administration following his arrest for alleged traffic violations.skip past newsletter promotionafter newsletter promotionHis family said he was “undergoing a physical and emotional recovery process” in his home country after police arrested him on 28 March for offenses that included having an expired tag and suspended driver’s license, before turning him over to Immigration and Customs Enforcement (Ice).The Florida Democratic congressman Maxwell Frost accused authorities of “kidnapping” Velázquez, who held an F-1 student visa. “Felipe Zapata Velázquez is just the latest victim of Trump’s disgusting campaign against immigrants,” Frost said in a statement.Two other cases which received widespread attention were those of Mahmoud Khalil, a recent Columbia University graduate who led pro-Palestinian demonstrations on campus last summer, and Rumeysa Ozturk, a Turkish student at Tufts University who was arrested in apparent retaliation for an op-ed she wrote that was critical of Israel. Both are in Ice detention fighting their deportations on the grounds that their actions constituted free speech under the first amendment. More

    Whatever Donald Trump does next, this chaos will soon be shaping ordinary lives for the worse | Gaby Hinsliff

    If it’s brown, lie down. If it’s black, fight back. If it’s white, say goodnight.The rhyme we learned hiking as a family through Yellowstone national park last summer is meant as a cheery reminder of how not to get eaten, if you meet a bear. Brown bears are best appeased by playing dead; black bears need to know this will hurt them more than it hurts you; and luckily there aren’t any polar bears in Yellowstone, because nothing deters them.Until this week the world remained unsure what kind of bear Donald Trump was. Keir Starmer treated him like a brown bear, dropping to the floor when threatened with tariffs and offering up a trade deal. China saw a black bear, to be met with maximum aggression. Though one day we may have to contemplate the prospect of a polar bear president – one who actually means what he said about invading his neighbours – for now what we actually seem to be facing is a crazy bear. There’s no discernible strategy or pattern here: just untrammelled ego, dragging the global financial system to the brink of meltdown and vaporising his own supporters’ retirement savings for no obvious reason beyond the pleasure of seeing impoverished allies desperately “kissing my ass”. And though this bear has lumbered back into the woods for now, seemingly spooked by a concerted revolt in the bond markets, the damage is done.What is still for the cheerfully news-avoidant just a faintly incomprehensible story about rising and plummeting stock markets will, in coming weeks, start shaping everyday lives for the worse. British businesses who have barely been able to work out if they’re coming or going for the last few weeks will pause big decisions while they try to calculate their losses. Our car and steel industries still face job-destroying higher tariffs, while Trump has talked ominously of new tariffs on pharmaceuticals to come (British drug companies rely heavily on US export markets). Along with all countries that did not retaliate against Trump, we remain saddled with a random 10% tariff on all exports, which could presumably still change on a whim. And if the US keeps up its self-harming tariff on China – now an eye-watering 145%, according to the White House, which is adding Wednesday’s 125% to the pre-existing 20% – then before long it won’t just be a case of prices rising for American shoppers but of trade between them breaking down completely, leaving American shelves empty. All this makes nervous consumers worldwide less inclined to spend and employers less likely to hire or invest, raising the risk of recessions – one reason that on Thursday, the markets fell again. There’s no security for working people in any of this, and vanishingly little prospect of growth. For a Labour government elected to deliver both, that is an existential challenge.You can either be the disrupter or the disrupted, Starmer warned his cabinet in February, rather startlingly for someone whose watchword was caution. His chief of staff, Morgan McSweeney, has however concluded that the new political divide isn’t left v right but “smash the system” v “look like the system and get smashed”. The obvious disruptive influence then was Nigel Farage’s resurgent Reform UK party, not a trade war, but one may now feed the other.Farage has gone very quiet lately about his now toxic friendship with Trump, but his local election message to England’s post-industrial heartlands is a blatantly Trumpian one about the glory days of manufacturing. This week he went to the pub with workers from British Steel’s endangered Scunthorpe plant – though it was Labour ministers who put in the unsung hours on a deal to save jobs there – before visiting a long-closed colliery to explain that he always thought the miners were betrayed. (Let’s just say that must have been an unusual view in the City, where at the time of the miners’ strike, Farage was working as a commodities trader.) It’s preposterous – Reform’s blend of tax cuts for the rich and dead-end nostalgia for everyone else would do nothing to revive former coal and steel communities – but Trump posing as the rust belt’s saviour seemed preposterous once, too. Farage knows where the electoral sweet spot is, in the seats where Reform is nipping at Labour heels: tacking right on issues such as immigration but left on economics. And while Starmer’s government is quick to compete with Reform on the former, it is more wary of the latter, even though ageing “red wall” voters now complain in focus groups of markets being rigged against them in ways that uncannily echo the disenchanted, Green-leaning southern young.But if Trump is really killing growth, meaning there will be no generous rising tide to lift public services and living standards, the only remaining options are either redistribution or accepting inexorable decline. Time, in short, to pick some enemies; to disrupt something before getting disrupted.Which markets genuinely are stacked against consumers? Who is making profits that can’t be justified? If Trump really has broken the old model, could it be built back better? This can’t mean uncosted, utopian leftwing populism but serious-minded, rigorous reforms that demonstrably put money back in ordinary pockets.What voters seem to want, the American data scientist David Shor and the writer Ezra Klein argued recently in a podcast on the confused desires underpinning American politics, is an “angry moderate”: someone who sounds as furious as they are about the state of things without seeming too frighteningly radical. There is plenty a British angry moderate could attack: from the ongoing debacle of Thames Water to the bafflingly opaque “surge pricing” now operated by everyone from concert-ticket vendors to pubs and hotels; from inequities in the tax system, or the way linking electricity prices to gas keeps them frustratingly high, to the outsourcing of social services that has left private equity firms running children’s homes and nursing homes for profit. (Not entirely alien territory to Rachel Reeves, who once told me that investigating the collapse of the outsourcing company Carillion as a backbencher changed her politics, and who has long embraced the idea of an activist state working to make life less precarious.) But whatever form it takes, offering people “shelter … from the storm”, as Starmer rightly has this week, should mean more than corporate bailouts. If not, anger with Trump could easily morph into anger with domestic governments’ inability to protect their own people from the fallout.He won’t be president for ever. But the mess he’ll leave behind, the jobs lost, the dreams smashed, the neighbourhoods spiralling downwards? That’s the polar bear, the thing that really eats governments. Fight, or say goodnight.

    Look on the bright side of Trump’s global tariffs | Letters

    Although environmental considerations will not have been a motivation for Donald Trump, it is worth examining whether a comprehensive revision of global trade tariffs – notwithstanding the significant transitional economic and human costs – could generate substantial environmental benefits (Here’s one key thing you should know about Trump’s shock to the world economy: it could work, 7 April).The prevailing model of liberalised global trade facilitates the transoceanic movement of consumer goods, often to countries that possess the capacity to manufacture equivalent products domestically. The associated carbon emissions from maritime and air transport are considerable, particularly given the volume of low-cost, frequently low-durability goods entering developed markets.Restricting free trade to essential imports – goods that cannot be manufactured or grown locally – would materially reduce transport-related emissions. Additional benefits might include enhanced food system resilience, improved biosecurity and increased regulatory autonomy over quality and safety standards.Thus, albeit unintentionally, President Trump’s trade policies could contribute to environmental objectives that are traditionally pursued by other means.Patrick CosgroveChapel Lawn, Shropshire Donald Trump’s tariffs – why the fuss? As an ordinary UK citizen I see only upsides. First, it’s the Americans paying the tariffs, not us. The resulting fall in the price of oil and the value of the dollar should reduce the cost of my petrol. As Americans switch to bourbon and Californian wine, the price of my scotch whisky and French wine should come down. If other countries send more of their goods to the UK to avoid the tariffs, this will force UK producers to become more competitive to the benefit of ordinary people like me.I believe that US citizens rich enough to buy Range Rovers and the like will not balk at paying a bit more, especially as the US equivalents are so clunky. If the steel tariff forces us to nationalise British Steel, good. As for the global economic system, this is structured for the benefit of big corporations and shareholders. Perhaps it is overdue for a change.Christopher WoodageCamberley, Surrey I have long believed that the way we choose to spend our money is a political act. With an overcautious Labour government in power, spending power remains an important act of resistance. Now more than ever, I urge readers to think carefully about what they purchase and, in particular, to boycott American goods. I have lived happily without an Amazon product for over 15 years, for instance, and with the added pleasure of knowing that my spending in local shops is benefiting the local economy. If we can’t rely on our government to stand firm, let’s do it for ourselves.Prof Mark DoelSheffield “I am telling you, these countries are calling us up, kissing my ass,” Trump said during a speech at the National Republican Congressional Committee dinner in Washington on Tuesday evening. Please let the UK not be one of the countries. Surely we have more self-respect than that.Ann ClewerCanterbury Looking at recent events, it seems Donald Trump is the most successful anti-capitalist since Lenin.Keith FlettTottenham, London More
