It’s a tableau no world leader — except perhaps President Donald Trump — wants to repeat. Convening in the Canadian Rockies for this week’s Group of 7 summit, presidents and prime ministers are hoping to avoid the acrimony that pervaded the last time this country played host to the world’s most exclusive club.

President Donald Trump rejected an Israeli plan in recent days to kill Iran's Supreme Leader Ayatollah Ali Khamenei, two U.S. officials told ABC News. The officials stated that Israel shared with the United States that they had a window to kill Iran's leader but the president was not on board with the plan.

Trump has often been a disruptor at global gatherings, badgering U.S. allies and competitors alike. But the dynamic could be different in 2025.

President Donald Trump's eventful week included securing a preliminary trade deal with China, deploying National Guard troops to Los Angeles, and responding to Israel's strikes on Iran.

President Donald Trump and Canadian Prime Minister Mark Carney will face off on Monday during the 2025 Group of Seven leaders summit in Canada, with their second meeting carrying higher stakes than their first.
