NO country needs nuclear weapons—not any of the nuclear weapons states and not India or Pakistan (or Israel for that matter). The Bharatiya Janata Party (BJP) is making a historic mistake in committing itself to exercising the nuclear option. The party's manifesto and, more recently, its national agenda state that a BJP government will "induct" nuclear weapons into India's defence. To the extent that this is a serious objective, it is profoundly mistaken. It is a mistake for a number of economic, diplomatic, political and moral reasons. But most of all it is a mistake for strategic reasons.
