I dont know why this ques arises?
The troubles we see there are all out either due to dirty policts or by the Paki's instigation. Let our Great Govt take a stubborn steps to revive the cool atmosphere and allow thoses people to live in peace. What may come, Kashmir belongs to our India and they are all my brothers and sisters. I will not just throw them away...

In fact it will be interesting. The Kashmiri's will realize their mistake if it happens.
They want to trade being a part of a secular democracy that is the world's 2nd fastest economy for being independent or part of a basket case (Pakistan)
Pakistan can't handle itself in 3 provinces (NWFP +FATA, Punjab, Baluchistan etc) so they will infect Kashmir instead of becoming peaceful like it.
If Kashmir remains independent or part of Pakistan for 3-5 years, there will be a Taliban style rule there.
And the Kashmiris will realize their mistake then.
