This war between the Taliban in Afghanistan and Pakistan is likely to go nuclear at some point. Why?

 It might be the ONLY way that Pakistan can win this war. This is likely why they will nuke the government seat in Kabul eventually.

I realized this today.

The Soldiers in the Pakistan Army are not usually zealots and only are soldiers for money and that's all.

Because of this the religious zealots of the Taliban are more motivated and ready to die guerrila style than the Pakistan Armies.

Because of this I can easily see the leader of Pakistan nuking Kabul where the Taliban seat of Government is completely out of existence. Would this work to keep Pakistan intact.

I'm not sure because you are dealing with religious zealots in Afghanistan who are ready to die and become martyrs for their cause no matter what. It's a part of their religious philosophy.
