During IK's term, you state that the situation improved. It improved in KPK because both the Taliban and the PTI were able to align ideologically and the Taliban in Afg decided not to ruffle the feathers during the latter's rule there while focusing on instability in Balochistan. Keep one thing in mind, like ANP, PTI would have been targeted had it continued. This is the nature of the evolving Taliban movement in Afghanistan. They want an ideological takeover in Pakistan similar to what they attained in Afghanistan. Their expansionist tendencies will not stop and this is the reason that their support for TTP is non-negotiable and PTI will eventually be seen by them as a party wedded to the Pakistani constitution. Also, while KPK was enjoying relative calm during IK's term, Balochistan insurgency was raging abetted from Afghanistan.
