You are naive. Every time back to the time of PM Sharif the GOP made deals with the Taliban to have peace as soon as the PA wwithdrew the Taliban broke the agrements and started killing minorities and those they considered opposed to their radical ideas and all possible harm ensured.
You better grow up and understand the realities of life. The terrorists are until they die or are killed of sheer terrorists.
True, some Pakhtun separatists have tried to take advantage of the chaos but they, too, have ended up on the short end of the stick and killed off before they can get a foothold to create a separatist nation which would not be pro-terrorist.
