Kindly read what I have written above again, where did I say Pakistan should give any territory to TTP? Where did I say appease the aggressor?
Secondly war is not an option here, if we do Airstrikes or operations inside Afghanistan, it will lead to conflict with Afghan Taliban which will cause huge destruction.
First, IEA & TTP are the same. The latter is a Pakistani extension of their Afghan counterpart. TTP's primary demand is handing over of FATA to them. IEA doesn't event accept the Pak-Afghan border, and considers entirety of KPK their territory. They are full of
hubris at the moment and
they do not want peace. These ceasefires are just time buying measures. In reality, they are playing good cop, bad cop game with you.
Second, we are already at war. Our people have been dying since last August. We have shown a lot of restraint.
Third, Afghan Taliban are no match for our armed forces in a conventional war. Their conventional force would be routed just like TTP was when it was occupying Pak territory. The destruction will be on their end. The only thing they are good at is guerilla warfare (hit & run, suicide bombings etc). You can't capture/hold territory with this kind of warfare. Furthermore, this won't be as effective if we tighten border control, and don't do a ground invasion (not on the cards).
The goal of any escalation will be to do so much damage that they are forced to the negotiating table for a reasonable settlement. What is that settlement? "You don't attack our territory, and we won't attack your territory".
