Political scientists and analysts have been churning out work on the India-Pakistan nuclear and conventional balance and its political implications, particularly since both countries tested nuclear weapons in 1998. Below are a few prominent books and articles worth looking at for those interested in how escalation, deterrence, and the nitty-gritty of war-fighting might play out. I don’t work on this topic, so I defer to these colleagues for their expertise (though there is often a range of differing opinion!).
This is just a limited sample of a much broader and richer literature, but a good starting point for people trying to figure out what is make of the current situation:
