Army operation is imperative in karachi to finish militancy and target killings.US should talk to the real stake holders of afghanistan to end the turmoil in this region and leave the area with respect.This has been verified by the classified papers of US and UK that "OSAMA" is not in pakistan so they should not blame it.Alqueda did bomb US's couple of targets but never attack in US neither the talibans.So talking with talibans will help very much and US can get guarantee from talibans that alqueda will never ever enter afghanistan,US can leave their bunch of "CIA" personel for verifications.People on both sides are bleeding for no reason.
