First of all, No person with a sane mind will ever talk of a nuclear war. All real nuclear powers display highest level of maturity when it comes to nukes.
Both India and Pakistan have given word (ZABAAN) under Simla Accord of 1972 that they both will address the Kashmir issue bilaterally. In almost all cultures giving Zabaan has a greate value, even greater than life in many cases. If you were not confident and capable of resolving the Kashmir issue bilaterally, you should not have agreed to it. The matter was anyways referred to the UN and a resolution was pending. So what made Pakistan undermine the UN resolution and agree to a bilateral negotiations? And even more intriguing is what makes Pakistan go back on its zabaan? And if the so called genocide of Kashmiris are such a big international issue then why no other nation ever talks about it?
And what is there to prove the covert operations of Pakistan in Kashmir when you guys openly admit it. Even Pervez Musharraf and many of your political leaders keep giving statements about it.
