It is "time to end America's longest war," US President Joe Biden will say Wednesday as he announces Washington's withdrawal from Afghanistan, which it invaded in the wake of the 9/11 attacks nearly two decades years ago. "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 according to prepared remarks. The US will continue to support the Afghan government against the Taliban, Biden will say, but "will not stay involved in Afghanistan militarily." The excerpts of Biden's remarks did not include a date for the withdrawal. On Tuesday officials said it would come before September 11, 2021, and would be without conditions, despite mounting fears of a return to Taliban rule. sms/st/ec
