Why do you think there is necassarily someone supporting them from outside?Who brought Taliban to Pakistan?Your own government,because that time they served your interests I suppose.
Those terrorists are brainwashed ideologically, I don't see why there should be some foreign country to blame.
I don't know about Sunni groups much, Shias have pick up arms in some cases to defend themselves.Not all of them are righteous, but do they attack regular citizens usually?
You got me wrong.I didn't say Pakistan is supporting them and you may have helped us defeating them.no denying in that.But do you agree with me that they were abusing situation and instability in Baloochestan region in Pakistan to carry out attacks against Iran?
