U.S. Military Withdrawal and Taliban Takeover in Afghanistan: Frequently Asked Questions [Updated September 17, 2021] [open pdf - 2MB]
From the Summary: "On August 15, 2021, the Taliban entered the Afghan capital of Kabul, completing a rapid takeover over the country with a speed that surprised many Afghans and Americans alike. The Taliban's advance came as the United States was completing the military withdrawal to which it agreed in the February 2020 U.S.-Taliban accord. The U.S. military and diplomatic withdrawal and evacuation operation concluded on August 30, 2021, with the departure of U.S. forces from Afghanistan. The fall of the elected Afghan government, which had been supported by billions of dollars in U.S. assistance over the course of nearly two decades, raises significant questions about past, present, and future U.S. policy for Members of Congress. This report provides material related to select questions associated with U.S. policy in Afghanistan[.] [...] The report concludes with some strategic considerations Congress may wish to contemplate as it assesses the situation in Afghanistan and its implications for the future."
