issue is that if army withdraws then once again ttp will gain foothold cause i recall watching an army officer sharing in powerplay war on terror series that even tho most of fata is cleared up but its still a hi risk security zone due to multiple factors one being proximity with afghanistan and thats why army is sort of still stuck in the area , plus in fata there are still some mischievous locals plus afghan refugees who support these ttp groups and will help them reorganize in these areas taking advantage of reduced armed forces presence, uskay baad jab us area may un terrorists nay wahan kay logon ki bajani hai and when just like past these terrorists will try to enter into pakistani major cities and blow themselves up tab sab ziada matam bhi pakistani army kay peechay in hi logon nay karna hai.Too late now, that should have been nipped im the bud right then and the establishment step in to give a very public punishment to rao anwar.
Now, its about fixing FATA overnight and the terror issues while still dealing with a nationalist Pashtun movement.
