President Biden outlined a U.S. international-coverage vision rooted in global alliances for the duration of his initially address to the United Nations as commander-in-chief, emphasizing the great importance of diplomacy at a instant when relations with some U.S. allies are strained.

Mr. Biden called for a change absent from armed conflict after two decades of war in Afghanistan and the Middle East. “As we shut this time period of relentless war, we’re opening a new period of relentless diplomacy,” he explained, standing in the U.N. assembly hall in front of the iconic serpentinite stone backdrop.
