I can gauge your intellect just by reading your comment. Your small brain doesn't understand the concept of MAD it seems. Nukes didn't fly at the height of the Cold War, what makes you think it will be used now?Pakistan has nothing to lose and everything to gain. India has everything to lose and nothing to gain.
If conditions engineer themselves to be just right, Pakistan will nuke you amidst a perfect storm.
Nukes exist as a form of both hard power and detterant, if both parties have nukes the effect is cancelled out. No nation and its leader is insane enough to use nukes whether it be Russia or fricking North Korea. Nukes are only good for rhetoric, if in a unlikely doomsday scenario its actually used humanity will lose as a whole, and the country which uses it will cease to exist.
India's or any other nations nuclear triad, mirv capability is just for detterance. Conventional war with modern warfare like drones and mechanized bots is what the future will bring.
