Tactical Nuclear Weapons (TNWs), often referred to as “battlefield”, “sub-strategic”, or “non-strategic” nuclear weapons, usually have a plutonium core and are typically distinct from strategic nuclear weapons. Therefore, they warrant a separate consideration in the realm of nuclear security. The yield of such weapons is generally lower than that of strategic nuclear weapons and may range from the relatively low 0.1 kiloton to a few kilotons. Pakistan’s quest to acquire tactical nuclear weapons has added a dangerous dimension to the already precarious strategic equation in South Asia. The security discourse in the subcontinent revolves around the perennial apprehension of a conventional or sub-conventional conflict triggering a chain reaction, eventually paving the way for a potential nuclear crisis haunting peace and stability in the region. Pakistan believes that the successful testing of the 60-km nuclear-capable short-range m issile Hatf-9 (Nasr) “adds deterrence value to Pakistan’s strategic weapons development programme at shorter ranges.” In paradox, the fact remains that this step has further lowered Pakistan’s nuclear threshold through the likely use of TNWs. The introduction of TNWs into the tactical battle area further exacerbates credibility of their control. Pakistan has not formally declared a nuclear doctrine, but it is well known that nuclear weapons are its first line of defence. The use of TNWs in the India-Pakistan case will alter the strategic scenario completely as Pakistan would threaten India with the use of TNWs in the event of New Delhi responding against Islamabad with a conventional strike in reaction to a 26/11-style terrorist attack. Pakistan forgets that given its offensive strategic posture and continuing involvement in terror strikes in India, it is New Delhi which is confronted with the problem of developing a strategy to counter Pakistan’s “first-strike” and proxy war in the light of its declared “no-first-use” policy. This edited volume attempts to address and decipher complex issues, including aspects such as China’s WMD collaboration with Pakistan, nuclear command and control dynamics within Pakistan, overall rationale and implications of TNWs, safety and security of nuclear weapons, scenarios for nuclear usage, India’s potential response options and, more specifically, the technical aspects of the Nasr delivery system.

Amidst many developments in the constantly evolving Indo-Pak conflict paradigm, the latest and perhaps the most intriguing has been the induction of Tactical Nuclear Weapons (TNWs) by Pakistan. While nuclear sabre rattling is not new to Pakistan's strategy, this time around there seems to be a strong pitch among security analysts to project these as the proverbial 'Brahmastra' in its possession, foreclosing any sort of military retaliatory strike by India. This is significant at a time when sporadic Pak sponsored terror attacks on Indian soil continue unabated. For the Indian security analysts this raises some pertinent questions. • Is the threat of TNWs credible enough to deter India from launching a suitable military response to a Pakistan supported terror attack? • Does induction of TNWs by Pakistan materially alter the Indo-Pak nuclear balance and consequently, the direction any future conflict may assume? • What are the response options for India to retain/ restore the nuclear as well as overall security balance? This book is an endeavour to find answers to all these. In the process, the author attempts to explore how the two protagonists view nuclear deterrence, what is the relevance of nuclear weapons for both of them, how are the fundamental drivers of the ongoing conflict and the ever changing dynamics and influences in the region affecting it. Using these parameters and the technical capabilities of TNWs believed to be held by Pakistan, the author constructs five possible scenarios for the foreseeable future. The outcome is interesting as it answers the fundamental question – are Pakistan's TNWs indeed the game changer they are being touted as or are we giving the devil more than his due?

The history of Pakistan's nuclear program is the history of Pakistan. Fascinated with the new nuclear science, the young nation's leaders launched a nuclear energy program in 1956 and consciously interwove nuclear developments into the broader narrative of Pakistani nationalism. Then, impelled first by the 1965 and 1971 India-Pakistan Wars, and more urgently by India's first nuclear weapon test in 1974, Pakistani senior officials tapped into the country's pool of young nuclear scientists and engineers and molded them into a motivated cadre committed to building the 'ultimate weapon.' The tenacity of this group and the central place of its mission in Pakistan's national identity allowed the program to outlast the perennial political crises of the next 20 years, culminating in the test of a nuclear device in 1998. Written by a 30-year professional in the Pakistani Army who played a senior role formulating and advocating Pakistan's security policy on nuclear and conventional arms control, this book tells the compelling story of how and why Pakistan's government, scientists, and military, persevered in the face of a wide array of obstacles to acquire nuclear weapons. It lays out the conditions that sparked the shift from a peaceful quest to acquire nuclear energy into a full-fledged weapons program, details how the nuclear program was organized, reveals the role played by outside powers in nuclear decisions, and explains how Pakistani scientists overcome the many technical hurdles they encountered. Thanks to General Khan's unique insider perspective, it unveils and unravels the fascinating and turbulent interplay of personalities and organizations that took place and reveals how international opposition to the program only made it an even more significant issue of national resolve.

For three decades, arms control treaties have provided a legal basis for limiting and reducing long-range nuclear weapons. However, thousands of sub-strategic, or tactical, nuclear weapons (TNWs) are not monitored or controlled by any existing treaties or formal agreements, even though they can pose security risks equal to or exceeding those of strategic nuclear weapons. As the world has seen, the rise of international terrorism highlights the potential dangers of tactical nuclear weapons. Because they can be relatively small and portable-particularly but not exclusively in the case of so-cal.

Using a constructivist model, this study brings nuclear arms control and disarmament back into the debates on the future of Indo-Pakistani relations. Constructivism recognizes the independent impact of international norms, such as the Nuclear Non-Proliferation Norm (NNPN), on India and Pakistan’s nuclear behavior. Even though the NNPN does not legally bind them, it is reinforced at the global level, and may lead the South Asian rivals to move in the direction of nuclear arms control and disarmament, thus reducing the costs, dangers, and risks of an eternal strategic rivalry. After examining the main tenets of constructivism in international relations, the works delves into the proliferation debate, discussing nuclear reversal and U.S. policy toward the subcontinent since the G. W. Bush administration. It looks at the prospects for nuclear arms control and disarmament in South Asia after the U.S.-India nuclear deal of 2008, and the nuclear abolitionist wave during the first Obama administration. It concludes with the contribution of social constructivism to understanding how changes in the India-Pakistan nuclear status quo can happen.
