this story is ambiguous
the decision to start operation in FATA was not a political gains/ loss but purely military, to take on the elements that were defined as enemy of the state and the threat to region/ world peace. the inaction presented far bigger threat and loss than the Qomi ghairat and sovereignty (with the TTP dismisses anyway)
with this in mind, pray tell what qualification did Imran Khan had to convince that withdrawing from the FATA was a good thing to do? whenever army gave way the TTP consolidated, punished the locals, slaughtered the Maliks and eliminated the leadership of tribal hierarchy. the state backed tribal militias stood no chance against the petro-dollar funded TTP who give Pak military run for its money. as per the SSG major who has led assaults against TTP, they have faced the TTP always using AP rounds, and are always equipped with the state of the art assault gear and are hardly surprised whenever attacked.
TTP will bring the front line to the suburbs of Peshawar and Hayatabad if you give way. the only gain here I see is political and some praise from the population living safely overseas and other settled areas of Pakistan. the say of the tribal area people doesnt really matter here because either they are with the TTP (or are sadly history or IDP).
having said that, I would welcome any dialogue with moderate elements (who are only defending themselves) or can be persuaded to berak way. but I dont think its easy.
the only way out of TTP fold is death. if the TTP doesnt get them, then the CIA drones get them. Naik Mohammad remember anyone?
its a childish notion that the people of tribal areas have picked up arms because of drones, they pass through the beheaded corpses of our soldiers hung in the bazars as if they are animals. has anyone seen the TTP fatwas for their favourite targets? how they advocate rape and murder?
this is a war of attrition and our only chance to fight them is to use their tactics on them, through targeted operations but its easier said than done. there are routes to and from Afghanistan and to the rest of the settled Pakistan, if they are not manned then the current chaos will only get worse.
