UNITED NATIONS (AP) — In a speech to the United Nations, President Donald Trump criticized the organization for being ineffective, highlighting America’s progress under his tenure while cautioning Europe about the dangers of flawed migration and green energy policies that he described as a “double-tailed monster” threatening its future.

During his nearly hour-long address to the U.N. General Assembly, Trump expressed a mix of complaints and self-praise, showcasing his achievements in office while warning that some nations led by his fellow world leaders are headed for disaster.

The speech served as a reminder to U.S. allies and adversaries alike that the U.S. has reverted to an unapologetic “America First” approach which holds a critical stance towards the United Nations after a four-year period with the more globally-oriented President Joe Biden. Trump also condemned the global body for its ineffectiveness, calling it full of “empty words” that fail to resolve conflicts.

“What is the purpose of the United Nations?” Trump questioned. “The U.N. has such tremendous potential. I’ve always said it. It has such tremendous, tremendous potential. But it’s not even close to fulfilling that potential.”

Subsequently, Trump sought to alleviate concerns from some diplomats by telling the U.N.’s top leader that the U.S. continues to offer “100%” support for the organization despite his criticisms.

“I may disagree with it sometimes, but I am fully committed to it because the potential for peace at this institution is significant,” Trump assured Secretary-General Antonio Guterres.

It was another about-face after Trump offered a weave of jarring juxtapositions in his address to the assembly.

He trumpeted himself as a peacemaker and enumerated successes of his administration’s efforts in several hotspots around the globe. At the same time, Trump heralded his decisions to order the U.S. military to carry out strikes on Iran and more recently against alleged drug smugglers from Venezuela and argued that “globalists” are on the verge of destroying successful nations.

Warnings about ‘green scam’ and migration

Trump touted his administration’s policies allowing for expanded drilling for oil and natural gas in the United States, and aggressively cracking down on illegal immigration, implicitly suggesting more countries should follow suit.

He sharply warned that European nations that have more welcoming migration policies and commit to expensive energy projects aimed at reducing their carbon footprint were causing irreparable harm to their economies and cultures.

“I’m telling you that if you don’t get away from the ‘green energy’ scam, your country is going to fail,” Trump said. “If you don’t stop people that you’ve never seen before that you have nothing in common with, your country is going to fail.”

Trump added, “I love the people of Europe, and I hate to see it being devastated by energy and immigration. This double-tailed monster destroys everything in its wake, and they cannot let that happen any longer.”

Trump makes dramatic shift on Russia-Ukraine war

Trump also addressed Russia’s war in Ukraine, once again threatening to hit Moscow with “a very strong round of powerful tariffs” if Russian President Vladimir Putin does not come to the table to end the war.

He waited until after the speech, and a meeting with Ukrainian President Volodymyr Zelenskyy, to announce a dramatic shift in his position on the war: He said he now believes Ukraine, with the help of NATO, can win back all territory lost to Russia.

Trump wrote in part in his post. “I think Ukraine, with the support of the European Union, is in a position to fight and WIN all of Ukraine back in its original form. With time, patience, and the financial support of Europe and, in particular, NATO, the original Borders from where this War started, is very much an option.”

The strengthened support from Trump, if it sticks, is a huge win for Zelenskyy, who has urged the American president to keep up the pressure on Putin to end his brutal war on Ukraine.

Trump going back to his 2024 campaign insisted that he would quickly end the war. And he’s frequently suggested that U.S. interests in the outcome were limited.

“Russia has been fighting aimlessly for three and a half years a War that should have taken a Real Military Power less than a week to win,” Trump wrote. “This is not distinguishing Russia. In fact, it is very much making them look like ‘a paper tiger.’”

Trump speaks out on Palestinian statehood push

The president also pushed back on longtime American allies who are using this year’s General Assembly to spotlight the growing international campaign for recognition of a Palestinian state, a move that the U.S. and Israel vehemently oppose.

France became the latest nation to recognize Palestinian statehood on Monday at the start of a high-profile meeting at the U.N. aimed at galvanizing support for a two-state solution to the Mideast conflict.

Trump sharply criticized the effort.

“The rewards would be too great for Hamas terrorists,” Trump said. “This would be a reward for these horrible atrocities, including Oct. 7.”

The president also took part in a group meeting with officials from Qatar, Saudi Arabia, Indonesia, Turkey, Pakistan, Egypt, the United Arab Emirates and Jordan for talks focused on ending the Gaza war.

“This is my most important meeting,” Trump said. “But this is the one that’s very important to me because we’re going to end something that should have probably never started.”

Trump pokes at UN for escalator, teleprompter issues

Early in his speech, Trump broke from his prepared remarks to bemoan an inoperable escalator in U.N. headquarters that he happened upon as well as a defective teleprompter.

“These are the two things I got from the United Nations: a bad escalator and a bad teleprompter,” Trump poked, eliciting laughs from delegates and leaders.

A U.N. official said the United Nations understands that someone from the president’s party who ran ahead of him inadvertently triggered the stop mechanism on the escalator. The official, speaking on condition of anonymity because of the sensitivity of the issue, said the White House was operating the teleprompter for the president.

Trump has Oslo dreams

The president again made clear that he wants to be awarded a Nobel Peace Prize, repeating his spurious claim that he’s “ended seven wars” since he returned to office.

“Everyone says that I should get the Nobel Prize — but for me, the real prize will be the sons and daughters who live to grow up because millions of people are no longer being killed in endless wars,” Trump said in his address.

Trump regularly points to his administration’s efforts to end several conflicts around the world, including fighting between Israel and Iran, India and Pakistan, and Egypt and Sudan.

“It’s too bad that I had to do these things instead of the United Nations doing them,” Trump said. “Sadly, in all cases, the United Nations did not even try to help in any of them.”

Although Trump helped mediate relations among many of these nations, experts say his impact isn’t as clear cut as he claims.
