The Taliban and other militant groups are also oppressing. When America leaves there will be a new set of problems ie just as there were pre-2001.
I dont defend those who kill innocent pakistanis but i want u to see the whole scenario.Its very complex problem and blamming one group will not solve the problem. Why Americ not leave Afghanistan, already defeated what else she wants. 99% problems will be solved when America will evacuate this land. Oppressors have to leave and specially in this region !
