President Trump used a 40-minute address at the United Nations to demand that the Islamic Republic of Iran choose between a deal and rapid annihilation, defending a more than six-month war that has cost the U.S. tens of billions of dollars and disrupted energy exports through the Strait of Hormuz and the Red Sea. He urged governments to join the complete economic isolation of Iran and rejected reports of U.S. munitions shortages. Trump also said artificial intelligence would be renamed super intelligence, or S.I., in U.S. documents and opposed regulation of the technology despite warnings about its risks. He defended military action against Caribbean drug cartels, criticized Mexico, called for change in Cuba, and highlighted a new law allowing tariffs of up to 100 percent on major purchasers of Russian energy and countries helping evade Russia sanctions. The speech came as Trump faced weak domestic and international standing, including a 32 percent approval rating, concerns about Republican losses in the midterm elections, unfavorable polling overseas, and a White House media dispute involving CNN, MS NOW and Politico.
