Mr. Trump was put on the defensive Tuesday by Mr. Macron, who during a tense 45-minute appearance aggressively challenged the American presidents vision for NATO and his handling of a military conflict involving Turkey. For Mr. Trump, it was a rare face-to-face meeting with another world leader in which he was not driving the conversation.

Mr. Trudeau participated in a more genial meeting with Mr. Trump later Tuesday.

Mr. Trump has long bridled at the idea of other world leaders poking fun at the United States. The world is laughing at us, he said frequently during his 2016 presidential campaign, criticizing the leadership of President Barack Obama.

In June 2017, when he announced that the United States would withdraw from the Paris climate agreement, Mr. Trump said that we dont want other leaders and other countries laughing at us any more. And they wont be. They wont be.

In 2018, after laughter broke out at the United Nations General Assembly when Mr. Trump claimed his administration had accomplished more than almost any administration in the history of our country, the president insisted that he was not the target.
