And not ridiculous things that are theoretically possible, like the Taliban does a 180 out of nowhere and converts to socialism and the imperialist states do a 180 out of nowhere and decide that a socialist middle east is cool.

Less civilians will die but that's about the only upside I see. Under the rule of the Taliban it will make Saudi Arabia look progressive.
