US military forces withdrew from Afghanistan on August 31, 2021, ending NATO's Operations Freedom's Sentinel and Operation Resolute Support. The US and its allies invaded the country in 2001, following the September 11 attacks, resulting in the war becoming the longest armed conflict in US history. But the United States could not permanently keep its troops in Afghanistan. They helped create and train the Afghan armed forces and national police, and left them $85 billion worth of weapons. Among those left in Afghanistan were 200 planes and helicopters, as well as 600 thousand small arms. But the Americans could not fight for the Afghan national forces forever. And the fact that they offered very little resistance to the Taliban and quickly surrendered to them is not the fault of the United States.
