Six of the Group of Seven leaders are trying on the final day of their summit Tuesday to show the wealthy nations’ club still has the clout to shape world events despite the early departure of U.S. President Donald Trump.Canadian Prime Minister Mark Carney and his counterparts from the U.K., France, Germany, Italy and Japan will be joined by Ukrainian President Volodymyr Zelenskyy and NATO chief Mark Rutte to discuss Russia’s relentless war on its neighbor.World leaders had gathered in Canada with the specific goal of helping to defuse a series of pressure points, only to be disrupted by a showdown over Iran’s nuclear program that could escalate in dangerous and uncontrollable ways. Israel launched an aerial bombardment campaign against Iran on Friday, and Iran has hit back with missiles and drones.Trump left the summit in the Canadian Rocky Mountain resort of Kananaskis a day early late Monday, saying: “I have to be back, very important.” As conflict between Israel and Iran intensified, he declared that Tehran should be evacuated “immediately”—while also expressing optimism about a deal to stop the violence.Before leaving, Trump joined the other leaders in issuing a statement saying Iran “can never have a nuclear weapon” and calling for a “de-escalation of hostilities in the Middle East, including a ceasefire in Gaza.” Getting unanimity—even on a short and broadly worded statement—was a modest measure of success for the group.At the summit, Trump warned that Tehran must curb its nuclear program before it’s “too late.” He said Iranian leaders would “like to talk” but they had already had 60 days to reach an agreement on their nuclear ambitions and failed to do so before the Israeli aerial assault began. “They have to make a deal,” he said.Asked what it would take for the U.S. to get involved in the conflict militarily, Trump said Monday morning, “I don’t want to talk about that.”But by Monday afternoon, Trump warned ominously on social media, “Everyone should immediately evacuate Tehran!” Shortly after that, Trump decided to leave the summit and skip a series of Tuesday meetings that would address the war in Ukraine and trade issues.The sudden departure only heightened the drama of a world that seems on verge of several firestorms. Trump already has imposed severe tariffs on multiple nations that risk a global economic slowdown. There has been little progress on settling the wars in Ukraine and Gaza.Trump’s stance on Ukraine puts him fundamentally at odds with the other G7 leaders, who back Ukraine and are clear that Russia is the aggressor in the war.The U.S. president on Monday suggested there would have been no war if G7 members hadn’t expelled Putin from the organization in 2014 for annexing Crimea.Trump on Monday demurred when asked if he supported Russia, saying “I only care about saving lives.”With talks on ending the war at an impasse, Starmer said Britain and other G7 members were slapping new tariffs on Russia in a bid to get it to the ceasefire negotiating table. Zelenskyy is due to attend the summit Tuesday at Carney’s invitation, along with other leaders including Rutte and Indian Prime Minister Narendra Modi.Trump declined to join in the sanctions on Russia, saying he would wait until Europe did so first.“When I sanction a country, that costs the U.S. a lot of money, a tremendous amount of money,” he said.Trump had been scheduled before his departure to meet with Zelenskyy and with Mexican President Claudia Sheinbaum.On the Middle East, Merz told reporters that Germany was planning to draw up a final communique proposal on the Israel-Iran conflict that will stress that “Iran must under no circumstances be allowed to acquire nuclear weapons-capable material.”Trump also seemed to put a greater priority on addressing his grievances with other nations’ trade policies than on collaboration with G7 allies. The U.S. president has imposed 50% tariffs on steel and aluminum as well as 25% tariffs on autos. Trump is also charging a 10% tax on imports from most countries, though he could raise rates on July 9, after the 90-day negotiating period set by him would expire.He announced with Starmer that they had signed a trade framework Monday that was previously announced in May, with Trump saying that British trade was “very well protected’ because “I like them, that’s why. That’s their ultimate protection.” Associated Press writers Will Weissert in Banff, Alberta, and Josh Boak in Calgary, Alberta, contributed to this story. —Rob Gillies and Jill Lawless, Associated Press
