Agreed. Kashmir cause, both for India and Pakistan died the day when both went nuclear. The problem we face now is not Kashmir issue itself, rather face-saving deescalation. For whatever it's worth, it's not going to happen in Modi's India............
Only issue that we should focus on to avert an all out war is water issue........ in the end it won't be Kashmir that will result in a nuclear holocaust, rather water.
But the Kashmir conflict- greatly- has to do with the water issue and the insecurities that arise with that for the two countries, as well as the security dilemma. The water and Kashmir issue are deeply connected, so unless the two countries find other ways to sustain their increasing population, Kashmir will in the end be an issue. The CIA released a report that puts the Kashmir issue as the most likely place for WW3 to start and there, it's not just about land, it's also about fresh water, which will prove to be a global problem pretty soon.
Also, forget being the chicken king of asia (not sure if you still have that ambition), I'd recommend investing in water. It will not only be good for you but also for Pakistan. And emperor when you control water, you can easily influence the politics greatly, esp when it starts becoming a scarce resource
