United Nations, Sep 23 (AP) President Donald Trump castigated the United Nations as a feckless institution in a speech to the world body on Tuesday, praising the turn America has taken under his leadership while warning Europe will be ruined if it doesn't turn away from a “double-tailed monster” of ill-conceived migration and green energy policies.

His roughly hourlong speech before the UN General Assembly was both grievance-filled and self-congratulatory as he used the platform to applaud his second-term achievements and lament that some of his fellow world leaders' countries were “going to hell." The address was the latest reminder for US allies and foes that the United States — after a four-year interim under the more internationalist President Joe Biden — has returned to an unapologetically “America First” posture with an antagonistic view toward the United Nations. Trump also sharply criticised the global body for inaction, saying it was filled with “empty words” that “don't solve wars.” “What is the purpose of the United Nations?” Trump said. “The UN has such tremendous potential. I've always said it. It has such tremendous, tremendous potential. But it's not even coming close to living up to that potential.” Afterward, Trump assuaged fears from some diplomats by assuring the top UN leader that the US remained “100 per cent” supportive of the global body despite his earlier criticism.

“I may disagree with it sometimes, but I am so behind it because the potential for peace at this institution is great,” Trump told 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 US 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.

The US president's speech, typically among the most anticipated moments of the annual assembly, comes at one of the most volatile moments in the world body's 80-year-old history. Global leaders are being tested by intractable wars in Gaza, Ukraine and Sudan, uncertainty about the economic and social impact of emerging artificial intelligence technology, and anxiety about Trump's antipathy for the global body.

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.” The passage of the wide-ranging address elicited some groans and uncomfortable laughter from delegates.

Trump holds one-on-one talks with world leaders Trump touted “the renewal of American strength around the world" and his efforts to help end several wars. He peppered his speech with criticism of global institutions doing too little to end war and solve the world's biggest problems.

General Assembly President Annalena Baerbock on Tuesday said that despite all the internal and external challenges facing the organisation, it is not the time to walk away.

“Sometimes we could've done more, but we cannot let this dishearten us. If we stop doing the right things, evil will prevail,” Baerbock said in her opening remarks.

The White House says Trump is meeting Tuesday with the leaders of Ukraine, Argentina and the European Union. He will also hold a group meeting with officials from Qatar, Saudi Arabia, Indonesia, Turkiye, Pakistan, Egypt, the United Arab Emirates and Jordan.

He'll return to Washington after hosting a reception Tuesday night with more than 100 invited world leaders.

Gaza and Ukraine cast shadow over Trump speech Trump has struggled to deliver on his 2024 campaign promises to quickly end the Israel-Hamas war in Gaza and Russia's invasion of Ukraine. His response has been also relatively muted as some longtime American allies are using this year's General Assembly to spotlight the growing international campaign for recognition of a Palestinian state, a move that the US and Israel vehemently oppose.

France became the latest nation to recognise Palestinian statehood on Monday at the start of a high-profile meeting at the UN aimed at galvanising support for a two-state solution to the Mideast conflict. More nations are expected to follow.

Trump sharply criticised the statehood recognition push.

“The rewards would be too great for Hamas terrorists," Trump said. “This would be a reward for these horrible atrocities, including October 7.” Trump also addressed Russia's war in Ukraine, saying that at the time of Russian President Vladimir Putin's 2022 invasion, everyone thought it would be a “quick little skirmish,” with Russia prevailing in a matter of days. Instead, the war has stretched on for over three years and counting.

The US president on Tuesday threatened to hit Russia with “a very strong round of powerful tariffs” if Putin does not come to the table to end the war. He said that would “stop the bloodshed ... very quickly” but also suggested fighting will not end as long as China and European nations continue buying Russian energy.

“They're funding the war against themselves. Who the hell ever heard of that one?” Trump said.

Trump has Oslo dreams Despite his struggles to end the wars in Ukraine and Gaza, Trump has made clear that he wants to be awarded a Nobel Peace Prize, repeatedly making the 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 offered.

He again highlighted his administration's efforts to end conflicts, including between Israel and Iran, India and Pakistan, Egypt and Sudan, Rwanda and the Democratic Congo, Armenia and Azerbaijan, and Cambodia and Thailand.

“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.
