South Asia is often viewed as a potential nuclear flashpoint and a probable source of nuclear terrorism. But, how valid are such perceptions? This book seeks to address this question and assesses the region's nuclear security from two principal standpoints. First, it evaluates the robustness of the Indo-Pakistani mutual deterrence by analysing the strength and weaknesses of the competing arguments regarding the issue. It also analyses the causes and consequences of nuclear arms race between India and Pakistan, the nature of deterrence structure in the region and the challenges of confidence building and arms control between the two countries in order to assess the robustness of South Asia's nuclear deterrence. Second, it assesses the safety and security of the nuclear assets and nuclear infrastructure of India and Pakistan. The author holds that the debate on South Asia's nuclear security is largely misplaced because the optimists tend to overemphasise the stabilising effects of nuclear weapons and the pessimists are too alarmists. It is argued that while the risks of nuclear weapons are significant, it is unlikely that India and Pakistan will give up their nuclear arsenals in the foreseeable future. Therefore, what needs to happen is that while nuclear elimination should be the long-term goal, in the interim years the two countries need to pursue minimum deterrence policies to reduce the likelihood of deterrence failure and the possibility of obtaining fissile materials by non-state actors.
