Important distinction which many are forgetting.
Pakistan is an Islamic republic and the vast majority of populace has Islamic sensitivities.
So we must not and cannot forget that we ourselves are accountable for our actions in front of God.
We are facing a dire and unfortunate situation in which the state is forced to take military action against another group that is comprised of Muslims and Khawarij (TTA and TTP et al.)
Islamically, a Muslim state can take military action against another group of Muslims (or khawarij, which are also Muslims per legal criteria), if that group threatens the safety and security of the citizens.
So from an Islamic perspective, an action might be permissible but not praiseworthy or one that has to be cheered upon.
The nature of this warfare has imposed on us that despite best efforts, we cannot avoid loss of innocent lives 100%.
That is why, to preseve or moral and muslim identity, it is very important to explain it to ourselves and to the world, that the state is forced to act in such a way, and is not neccassirly pleased with the state of affairs.
Despite our hatred for Afghans at the moment, we must not forget that cheapening of Afghan blood, is inturn, cheapening of the Muslim blood. At the end of the day, they pray towards the same Kaaba and have the same kalimah.
We kill because we have to, not because we are bloodthirsty. We will stop when we see any opening that allows us to ensure our security without killing.
This is important to understand because we are operating in a weird binary. Either the Afghans are sacred brothers or they are vile namak harams that deserve massacare. The point is that the Islamic framework allows the state to take military action without us dehumanizing Afghans specially the TTA that we have courted for decades.
There is no point in burning all bridges because no matter how much explosives are dropped, at the end of the day we will be negotiating with them. This will happen today or tommorrow, but it will. Militray action is only to allow us to negotiate from a position of strength.
