I agree, Americans have no business being in our part of the world.
But since America is a super power, and this area has become a breeding ground for terrorism which struck USA on 9/11, America has to make sure that this area stops breeding terrorism which strikes the west.
As long as this area is no longer breeding terrorism which can attack the West, America won’t care about this area.
the taliban are not interested in global terrorism but are too stupid to realize that what is in their best interest is to stop sheltering these arab terrorists like al qaeda who have global aspirations.
If the taliban give up al qaeda and pledge never to host foreign arab terrorists in this area, then America will leave.
