What was not inevitable was the way USA left. No one disputes that the American people for the most part and no matter the party, wanted out. It could have been any year that they leave and have a disaster or it could be any year that they leave and do it safely without leaving in a sloppy way that put allied countries' people in danger or the Americans there in danger. Why did Xiden leave the military equipment? Now for years to come Taliban is well-armed.
