World Leaders Convene at UN Amid Wars and AI Risks

World leaders are set to convene in New York for the United Nations General Assembly high-level week, beginning September 22, 2026, as the institution grapples with escalating conflicts in the Middle East and Ukraine, emerging risks from artificial intelligence, and a contentious leadership transition. The gathering, expected to draw nearly 130 heads of state, occurs against a backdrop of what UN Secretary-General António Guterres has described as an era of deep uncertainty, with the post-World War II international order under significant strain. The agenda is dominated by the ongoing US-Israeli war with Iran, which has driven global inflation and destabilized the region, and recent gains by Houthi militants in Yemen that threaten shipping in the vital Bab el-Mandeb Strait. Russia's full-scale invasion of Ukraine, now in its fifth year, also looms large, with Ukrainian President Volodymyr Zelensky expected to appeal for continued support ahead of another difficult winter.
