On the one side, India has six times the population, an economy that’s eight times bigger, and has a correspondingly larger military.
On the other side, Pakistan has crazy jihadis who are eager to kill and don’t care that much about dying. Plus 10% of the Indian population is Muslim, and any war with a Muslim country may see them rising up inside India.
In any major Hindu/Muslim conflict, expect India’s Muslim population to be early targets for the Hindus.
The Hindus can get crazy too, to a lesser extent.
