WATCH: Trump's boasting at UN General Assembly draws laughter from world leaders

President Donald Trump delivered a sharp rebuke of multinational authority at the United Nations on Tuesday, drawing headshakes and even laughter from fellow world leaders as he boasted of America’s economic and military might.

Trump arrived late, forcing a last-minute scheduling switch, then received polite applause but also blank stares as he took his blustery brand of “America First” policies to the annual General Assembly.

Speaking in triumphal terms, Trump approached the address as an annual report to the world on his country’s progress since his inauguration. He crowed that in “less than two years, my administration has accomplished more than almost any administration in the history of our country.”

Rather than applaud or indicate they were impressed, the audience began to chuckle and some broke into outright laughter. Trump appeared briefly flustered before joking that it was not the reaction he expected but “that’s all right.”

The moment only reinforced Trump’s isolation among allies and foes alike, as his nationalistic policies have created rifts with erstwhile partners and cast doubt in some circles about the reliability of American commitments around the world.

Trump goes on attack

Trump seized his opportunity to assert American independence from the international body. He was unapologetic about his decisions to engage with the erstwhile pariah North Korea, remove the U.S. from the international Iran nuclear accord and object to U.N. programs he believes are contrary to American interests.

“We reject the ideology of globalism and we embrace the doctrine of patriotism,” Trump said.

He referenced a long list of U.N. initiatives, from the International Criminal Court to the Human Rights Council, that his administration is working to undermine.

“As far as America is concerned, the ICC has no jurisdiction, no legitimacy and no authority,” he said. The U.S. is boycotting the Human Rights Council, arguing it overlooks abuses by some and serves as a venue for anti-American and anti-Israeli action.

Trump’s denunciation of globalism drew murmurs from the room that stands as the very embodiment of the notion.

Other tense moments included his criticism of Germany’s pursuit of a direct energy pipeline from Russia, which drew a dismissive headshake from a member of the U.S. ally’s delegation. His mention of the United Arab Emirates, Saudi Arabia and Qatar all in one breath, was received by stone-faced Saudi officials. The UAE and Saudi Arabia have been boycotting Doha since last year as part of a political dispute tearing apart the typically clubby Gulf Arab nations.

The laughter in the first moments of the address evoked a campaign line Trump frequently deployed against his predecessor Barack Obama — who embraced international engagement — suggesting that due to weak American leadership, “the world is laughing at us.”

In 2014, Trump tweeted “We need a President who isn’t a laughing stock to the entire World. We need a truly great leader, a genius at strategy and winning. Respect!”
