It’s going to happen sooner or later... The only difference between doing it now and doing it later is that now it will be on your terms and later you will have no choice but to accept it.
Think about it... Iran is a religious nation, Afghanistan will soon be a religious nation, India is pushing their Hinduvta and relinquishing their secularism; Where will Pakistan be in all of this, you don’t in the slightest bit think any of this will leave Pakistan uninfluenced?
No power on earth can undo Pakistan. We live by our Quaid's words. I don't care who wants borders to be erased, and a caliphate established. Pakistan won't be a part of something which erases its existence.
Enough said.
