Not a happy thought!
Indian and Pakistani relations are a very strange bird. Just when it looked like things were going to boil over in a nuclear standoff last year, they made up and decided to pursue peace. Many incidents have occurred since then, but the sparring rhetoric is gone. It seems to me that the Indians and Pakistanis agree that events like this are horrible for both countries, but the tinderbox in Kashmir is so unstable, retaliatory action by either side could devolve into an internal coup in Pakistan, which nobody wants on either side. It's as if both sides have decided that the best bet is to put Kashmir into an isolation tank and build diplomatic relations at the same time. My guess is that neither governments would lose any sleep is Kashmir disappeared from the map.
