Lessons from the Collapse of Afghanistan’s Security Forces
Abstract: Six themes emerge from a close examination of the Afghan National Defense and Security Forces’ (ANDSF) collapse in 2021: the ANDSF collapse was months—if not years—in the making; the United States did not give the ANDSF everything they needed to be independently successful; the ANDSF did put up a fierce fight in many areas; the ANDSF were poorly served by Afghan political leaders; the ANDSF were poorly served by their own commanders; and the Taliban strategy overwhelmed and demoralized the ANDSF. From these themes, there are three key lessons: the ANDSF’s failure had many fathers; the U.S. model of security assistance requires reform; and greater emphasis on non-material factors (e.g., morale) is needed in future security force assessments.
