Nuclear weapons cannot obviate wars, but can change its complexion and influence the manner of its conduct. In order to keep nuclear weapons from entering into real warfare, it is important to intelligently judge an adversary's nuclear thresholds and to calibrate one's own conventional strikes. For India, the exploration of this space is particularly important in order to deny Pakistan a free hand to indulge in sub-conventional conflict even as it holds the threat of an all-out nuclear war against an Indian conventional response.

Although the broad contours of India's nuclear doctrine were announced within the days of May 1998 nuclear tests, the formal doctrine was made public only five years later. This article will critically examine the evolution of India's nuclear doctrine in terms of the 1999 Kargil conflict and the 2001-2002 military confrontation with Pakistan. This article concludes that the one-page nuclear doctrine of 2003 remains sketchy and subject to varied interpretations.

The Kargil conflict can be categorized as a 'limited war'. It was initiated by Pakistan to achieve mixed military and political objectives, but made important misjudgments that doomed the enterprise to failure. The questions discussed in this article are: why was India surprised; why did both countries observe such great restraint; did the Kargil conflict have a nuclear dimension; and is 'limited war' a viable concept with nuclear deterrence obtaining in South Asia. It also argues that the Kargil conflict was an exception, in some dimensions, to the 'stability-instability paradox'

Ten years later, the Kargil War still arouses deep emotions turning around Pakistan's gross perfidy, an intelligence failure, great heroism, military improvisation and innovation, a national upsurge, a most open inquiry leading to a comprehensive review of vital issues long closed to scrutiny and reform. Its report, prepared in record time, was uniquely presented to the nation as a commercial publication. (From Surprise to Reckoning: The Kargil Review Committee Report, Sage, New Delhi, December 1999.)

In May 1998, India and Pakistan surprised the world by carrying out nuclear weapon tests. The tests were followed by two developments. The positive development was Lahore Summit in February 1999. In a simultaneous negative development, Pakistan initiated the Kargil war. Due to difficult terrain, inadequate intelligence and poor surveillance, it took time to clear the initial fog of war. Later, despite a self-imposed strategy, Indian forces responded with a resolve and daring that few believed was possible.
