Trump returns to UN as Iran war shakes global economy and world body faces funding crisis

President Donald Trump is set to address the U.N. General Assembly on Tuesday amid global economic turmoil caused by his decision to launch a war against Iran, alongside rising anxiety over artificial intelligence and the U.N.'s future due to reduced U.S. financial support. Trump's address comes as the Iran war, now nearly seven months old, has disrupted oil markets, with Brent crude hovering around $100 per barrel and shipping lanes under threat from Iranian-backed rebels. He will also hold talks with British, Japanese, and Venezuelan leaders, and sign a Greenland agreement with Denmark. The war has become a political liability for Republicans ahead of midterm elections, while Trump is expected to defend his leadership and may soften his criticism of the U.N. He also faces frustration over the Russia-Ukraine conflict, which he had promised to end quickly.
