In the middle of 2021, despite two decades of effort, the Afghan government collapsed in just nine days. The United States failed to create a state with the capacity to control its own armed forces or local officials. As early as 2009, eight years into the intervention, Ambassador Karl Eikenberry had already noted that the Afghan government could not carry out most state functions and that its leadership showed little interest in trying. U.S. civilians and soldiers tried to fill the gap.
