In 2021, the U.S. took significant action by withdrawing its military forces from Afghanistan after nearly two decades of involvement in the region. This decision was largely influenced by an agreement made in 2020 between the U.S. and the Taliban, which outlined a timetable for troop withdrawal. The withdrawal culminated in a rapid takeover of Afghanistan by the Taliban in August 2021, leading to chaotic scenes at Kabul's airport as many Afghans attempted to flee the country. The U.S. military’s exit marked a major shift in U.S. foreign policy and raised significant concerns about the future stability of Afghanistan.
