Let's not be so foolish here! Both countries are very capable of sending each other to oblivion. In you hyped up case of only Pakistan becoming a no mans land, 70% plus of India will become that too and all of suburban India will be decimated too. So plz don't live in a fool's paradise that India will survive. A 200million populated Pakistan is well capable of leaving India with nothing but 200million farmers/villagers. Is that the future you want of India?
As someone so rightly said, Pakistan is not the only muslim country whereas India is the ONLY hindu country .... india should survive as a piece of a huge patchwork of nuclear wasteland, but will it really be India anymore that you see it today ... very unlikely if nuclear war breaks out. Americans couldn't stop Japanese suicide pilots and had to resort to a nuclear bomb, you think we Pakistanis will just sit back and let you both us without taking you to wherever you believe in afterlife with us? Keep dreaming. Nuclear warfare is not a joke.
