Trump restarts war with Iran and plays nice(ish) with Nato

From the Guardian Investigates team: Across the world, hundreds of people have come to believe they have made extraordinary scientific discoveries with AI chatbots such as ChatGPT, Claude and Gemini.

In August, the Democratic senator from Georgia, Jon Ossoff, implied Donald Trump was not interested in being president because he just wanted to ‘build his ballroom and travel with Natalie’. The implication Trump was having an affair with his aide (which he denied) rattled Republicans and excited Democrats. This week, Jonathan Freedland speaks to David A Graham of the Atlantic about why Ossoff is now a potential candidate for 2028

In the past couple of weeks, the Trump administration has reignited its trade war with Canada, threatened an ‘economic D-day’ against Iran and watched the US national debt surpass $40tn.

With less than three months to go until the midterms, voters are thinking about grocery prices, the Iran war – and datacentres. This week, Jonathan Freedland speaks to the historian Jill Lepore about how this latest AI backlash could influence those all-important elections in November.

When Air Force One took off from Turkey after July’s Nato summit, almost everyone believed Donald Trump was on board … but he wasn’t.

Donald Trump’s second term is unlike his first. The politicians who challenged him are gone. The lawyers who once pushed back now choose their battles. What remains is an imperial president with almost no internal checks, using executive power to reshape everything from the economy, immigration and even the presidency itself. Few journalists have covered Trump as closely as the New York Times journalist Jonathan Swan. Jonathan Freedland speaks to him about how the president has consolidated such power – and what it could mean for the US and the world

Leftwing Democrats are having their moment in the sun, with Zohran Mamdani in New York, Abdul El-Sayed in Michigan and endless calls for Alexandria Ocasio-Cortez to run for president in 2028.

Jonathan Freedland speaks to Bhaskar Sunkara, president of the Nation magazine, founding editor of Jacobin and author of The Socialist Manifesto: The Case for Radical Politics in an Era of Extreme Inequalities

Donald Trump has announced a landmark nuclear deal with Saudi Arabia while pressing ahead with efforts to stop Tehran from developing a nuclear weapon.

The debate about how old is too old to serve in public office has resurfaced this week after the shock death of the Republican Lindsey Graham and the surprise return of Mitch McConnell, the 84-year-old senator who published a photo of himself in hospital after a long absence from the spotlight. With rumours continuing to swirl around Donald Trump’s health, why is it that US politicians seem to cling on to power for so long? Jonathan Freedland speaks to Alexis Coe, a presidential historian and columnist for the New York Times Book Review, about whether the US is becoming a gerontocracy

After the US launched strikes on Iran this week, Donald Trump said the fragile ceasefire he had co-signed just last month was over. He also reignited his threats to take Greenland, before leaving the Nato summit in Ankara, saying there was a lot of ‘love’ and ‘unity’ in the room. So how does anyone make progress with a leader choosing to relive a diplomatic Groundhog Day? Jonathan Freedland speaks to Susan Glasser of the New Yorker
