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.
I used to think that the best thing that could happen is a Marshall Plan for the Middle East, but now, I'm not so sure that would be good.
Right now the Taliban are winning faster than they expected. At the moment we just have to see if they can govern Afghanistan successfully or it turns into warring factions.
Considering that peace is their number 1 selling point, there would have to be some abysmally shortsighted warlord to spur faction conflict
