President Donald Trump will return to the world stage for this weekend’s 50th Group of Seven leaders summit in Canada. But Trump’s first multilateral summit of his second administration comes as Israel and Iran push the Middle East to the precipice of war and many of his G7 allies are under pressure

The last time Canada played host, in 2018, Trump left the summit before denouncing then Canadian Prime Minister Justin Trudeau as "very dishonest and weak" and instructing the U.S. delegation to withdraw its approval of the final communique.
