And lets not forget that FATA has become not only a hot bed for Local Talibs and foreigners fighting in Afghanistan, but also for Punjabi and other terrorists who are hell bent on killing ever Shia they can find. The Pak Army obviously cant fix the problem, atleast not on its own...
Similarly lets not forget that the tribes in FATA are themselves victims of US, Pakistani, and Taliban terror. The fact that tribal hierarchies have been displaced and probably for the first time ever FATA refugees had crossed over to Afghanistan. the best shot for FATA is to 1. Continue empowering the tribes 2. Peace deals stopping attacks on Pakistani soil 3. Pushing them toward Afghanistan (where they should be fighting anyway).
