I hate to talk about nuclear war. It is a catastrophe. Innocent lives laid to waste for few people's sense of insecurity. But to counter your argument, I am really surprised how misinformed you are about Indian nuclear programs and over-confident about Pakistan's. We can completely annihilate Pakistan within hours as they are our immediate neighbours but Pakistan can't do the same given our huge land area and population, various economic hubs, ports etc. By the time they launch their 10th nuke they'll be gone. Massive destruction is assured but not mutually assured destruction. They can only threaten us more and can hurt us less. That is the reason they resort to threatening whenever it is not necessary at all eg: speech of joke Sartaj Aziz after NSA-level meeting was called-off by them. P.S: I consider comparing India with a nation like Pakistan as a shame.
