President Donald Trump arrived at the 52nd G7 Summit in Évian-les-Bains, France, on Monday with an Iran ceasefire deal already announced, stayed for the full three days, signed the leaders' declarations, and left declaring the gathering a "Great Success" on Truth Social.

It was Trump's fifth G7 summit in person and took place amid two active conflicts, in Iran and Ukraine, as well as deepening fractures over China, trade, and NATO. The dynamic was not a Western alliance confronting Trump, as many pundits predicted, but Western leaders adapting to his agenda.

The summit was effectively dominated by the Iran ceasefire agreement from the moment Trump landed. A senior U.S. official briefing reporters described the deal as one that "allows us to open the Strait of Hormuz immediately, commits the Iranians to destroying the nuclear dust," and establishes a framework where Iran's compliance triggers gradual sanctions relief, adding it "commits us to quite literally nothing."

One senior French official told reporters the agreement "boosts the chances of the G7 being more constructive as we can now really talk about something operational." A formal signing ceremony was scheduled for Geneva on Friday.

Trump received broad backing from the other leaders. Macron called the deal a "very good deal," saying allies support it "because it's an agreement that puts a stop to a situation of great instability that had terrible consequences for our economies."

Canadian Prime Minister Mark Carney called it a "game changer" and pledged Canada's support for implementation. The leaders' statements, notable for the U.S. signing on, praised Trump for the agreement and pledged tougher sanctions on Russia.

On the final morning, Trump arrived almost an hour late, with Treasury Secretary Scott Bessent filling his chair as Macron told the room Trump would arrive "in a while." When he entered, Trump stopped at the head of the table, turned to the assembled leaders, and delivered what will likely become his signature line, "I'm the boss," drawing a laugh. He gave British Prime Minister Keir Starmer a pat on the shoulder and sat next to Macron. French officials expressed satisfaction that Trump stayed for the entire summit, in contrast to the previous gathering in Canada, where he left early.

Trump held bilateral meetings throughout the three-day summit. He met with Macron and separately with Indian Prime Minister Narendra Modi at what was described as a difficult moment in the U.S.-India relationship. Three Indian sailors had been killed in a U.S. military strike on a tanker in the Gulf of Oman during the American blockade.
