Trump returns to UN amid anxiety over Iran, AI, and the world body's future

President Donald Trump is set to address the U.N. General Assembly on Tuesday amid global turmoil from his war with Iran, rising anxiety over artificial intelligence, and questions about the United Nations' future as he reduces U.S. financial support. Trump will hold talks with British Prime Minister Andy Burnham, Japanese Prime Minister Sanae Takaichi, and Venezuela's acting President Delcy Rodríguez, plus meet Gulf Cooperation Council leaders to discuss the Iran war and rebel attacks on Saudi Arabia. His foreign policy, especially the Iran conflict, is straining Republican midterm hopes, though officials say he will argue the world is better under his leadership. The war, nearing seven months, has killed much of Iran's leadership and crippled its military, but oil prices remain near $100 a barrel with shipping lanes threatened. Trump may also address Russia's Ukraine war, which he promised to end quickly, and is set to sign a Greenland agreement expanding the U.S. military footprint.
