Speaking before a standing-room-only audience at the UN headquarters in New York, Trump defended his administration's decision to strike Iran in February and claimed he now faced a "big decision": strike a deal that allows Iran to rebuild, or "annihilate the Islamic Republic and do it quickly."
"Do I drive them into hell with no chance of survival and no hope of future greatness for generations?" Trump said, as a representative for Iran's delegation sat stony-faced in the audience. He added that he believed a deal would be made after the US midterm elections in November, suggesting Iran was "waiting to see how I do."
Trump also called on allies to enforce the "complete economic isolation" of Iran, arguing that if nations stand united, "oil prices will come plummeting down even lower than they were at the start of the conflict."
The president's speech struck a markedly different tone from that of UN Secretary General António Guterres, who earlier warned that global divisions were deepening and underscored the importance of international interdependence.
Trump ridiculed the threat of artificial intelligence, which he has previously called a "hoax," and announced he was ordering the US government to stop using the term "artificial intelligence" in official documents, replacing it with "super intelligence." "The use of the word 'artificial' makes intelligence fake, it makes it sound fake and it is not fake," he said. "It's actually amazing."
The move directly contradicts a statement signed on the sidelines of the UN summit by 22 nations, including Australia, calling for international controls on frontier AI models. Australia's Prime Minister Anthony Albanese was among those who signed.
Trump also predicted the imminent end of the Russia-Ukraine war, saying, "It's going to happen, I think, more quickly than people understand." He suggested Cuba's communist government "will fall," prompting a walk-out by the Cuban delegation.
The address, delivered six weeks before the US midterm elections, was seen by observers as an attempt to push back against growing criticism that Trump's foreign policy has destabilised the world and harmed American interests.
