Our original purpose 20 years ago was to stop al qaeda from further intrusions into our country to do damage. We found and killed Osama bin Laden. We stopped al quaeda. A small force on the Afghan-Pakistan border would have done the job. We didn’t need to spend billions building an army for the Afghanis. They wouldh’t use it properly anyway. We knew that. It was a bonanza for the arms merchants and money in the bank for the rulers. Getting out was the right thing. Afghanistan is not our responsibility. And certainly not if they themselves don’t care. It’s a travesty that after billions of dollars spent on them, the Afghan army couldn’t even hold on for enough time for us to get out reasonably.
