India face an assymetrical challenge as far as Nuclear weapons go. One one hand, we lose option of first use of nuclear weapons in a decapitating strike on Pakistan and on another hand we are forced to invest massively in SLBM / SSBN program, BMD program, space based missile launch detection program. Not to mention, the sheer threat of nuclear weapons have made our conventional weapon superiority worthless. This makes nuclear weapons a pretty dud and self-defeating investment for us. Shouldn't we be declaring that if Pakistan does not declare no-first-use policy, we should also reserve the right to strike them first with a de-capitating strike. This will force Pakistan to also 'invest' in BMD and survivable nuclear weapons. Right now, nuclear war is an option for Pakistan and a compulsion for India.
