How does this work? Let's say tomorrow China attacks India and doesn't at all nuclear weapons - what do you think India will do? Just use nuclear weapons on China and then of course Chinna does that too and they happily annihilate each other into sunset? I can imagine this being done by a completely failed state with nothing to lose and that too is maybe (NK? Maybe even PK though I am not really sure about this one).

As cheeky as it sounds we might need "greener" and "safer" alternatives to nukes but retaining the power for immediate devastation :D
