WASHINGTON (AP) – President Biden will withdraw all American troops from Afghanistan over the coming months, U.S. officials said, completing the military exit by the 20th anniversary of the Sept. 11, 2001, attacks that drew the United States into its longest war. Biden declared on Wednesday that the Sept. 11 attacks, which were coordinated from Afghanistan, cannot justify American forces still being there 20 years after the deadliest terror assault on the United States. Biden called the U.S. military presence the nation’s “forever war.” He said at the White House that he is the fourth American president to preside over an American troop presence in Afghanistan and he “will not pass this responsibility to a fifth.”
