Only option Pakistan has left in case of conflict is to hut back hard and escalate it rapidly, they can't fight long drawn war so emphasis will be to escalate quickly and bring in UN and other countries.
For those who think Pakistani nuclear blackmail days are over I don't think so. They will present a credible deterrence, at least that's what their game plan looks like and for that they will strike India with missiles too trying to inflict huge number of casualties. Ball will be again in Indians court if we want to test our nuclear contingency plans with world breathing down our necks or we just let it go for the time being.
Do not count the Pakistan out yet, our nation is not prepared to handle huge casualties figures and in a big relief to Pakistan, the Congressi ecosystem (some clowns present even here) will divide the country and build pressure or blame Modi with everything those vultures got for electoral gains. Pakistan on the other hand does not have such problem as army can pick up anyone who talks against them. For a common Indian it maybe war of respect and getting back what's our but for vultures it's an opportunity to get power back. There are ways to tackle that but I don't know if government will enforce them, I even doubt Modi will be able to sustain that pressure after he chickened out on 27th Feb night.
I just hope we stretch it long, keep it limited and hammer them just enough that they can't escalate or hide.
