When the two men met Monday in New York, they shook hands lightly and got down to the tasks at hand. They agreed to disagree on the Iranian nuclear accord and Trump’s protectionist policies and one-sided support for Israel, according to two French presidential advisers.

The businesslike mood contrasted with Trump’s fawning over Macron at a state dinner in April, and Macron’s lavish Eiffel Tower welcome for the Trumps last year.

Hours after their meeting, the two men laid out starkly different worldviews in speeches at the U.N. General Assembly.

“Nationalism always leads to defeat,” said the progressive, multilateralist Macron.
