On Wednesday, Biden will formally announce his decision to withdraw all American troops before September 11, the 20th anniversary of the terrorist attacks on the World Trade Center and the Pentagon that led the US into its longest war.
"We cannot continue the cycle of extending or expanding our military presence in Afghanistan hoping to create the ideal conditions for our withdrawal, expecting a different result," Biden will say in his remarks, scheduled for 2:15 p.m. ET on Wednesday.
"I am now the fourth American president to preside over an American troop presence in Afghanistan. Two Republicans. Two Democrats," he will say. "I will not pass this responsibility to a fifth."
In a sign he views his remarks as a historic bookend to the prolonged conflict, he will deliver them from precisely the same spot in the White House Treaty Room that President George W. Bush announced the start of the war on October 7, 2001. Afterward he'll visit the section of Arlington National Cemetery where many of America's war dead from Afghanistan are buried.
