I think your intentions are good but you underestimate what politics of countries want. IF India says today that the pre requisite for Kashmir to be handed over to Pak is to have all Kashmiris migrate to India Pak will jump at the offer else they would not have closed the doors on Indian Muslims to move to Pakistan.No; Pakistan doesnt want land - it wants to see Kashmir free. For many Pakistanis this is a personal issue - since a quarter of Punjab's population is Kashmiri and a massive segment of our elite/military/government (including Nawaz Sharif) are Kashmiris.
When you hear news of your kinsmen being killed in the streets, rape incidents, harassment and overall oppression; it turns into a personal issue.
We'll let the Kashmiris decide what they want to do.
Likewise on the killing, when babri masjid came down Pakistan sponsored Dawkins to bomb Mumbai. There was no kinsman killed at that time. It's the nature of Pakistan to destroy India.
