Three million would die in "limited" nuclear war over Kashmir

That's just the direct count. It doesn't count the starvation and cancer that would surely follow, or the loss of life following from the disruption of normal services. Or the civil war in Pakistan. And it's an optimistic figure anyway in my opinion. They're working off of the Hiroshima and Nagasaki data, and I think the weapons used will probably be more effective than the scientists expect. We don't really know how good the Indian and Pakistani nukes are.
