They won't mess with us but the bloodshed and revenge that the Taliban will impose as they drag Afghanistan back to the ninth century won't be pretty. Wouldn't want to be an educated Afghan woman, or educated Afghan man for that matter, for all the money in the world once they're back in control.
The ultimate consideration is it is the Afghan’s country so it’s up to them. The US cannot continue as global cop and nation-builder: it’s too expensive in $$$ and lives plus contrary to the importance of self-determination being the key to success.
