Getting to Zero takes on the much-debated goal of nuclear zero—exploring the serious policy questions raised by nuclear disarmament and suggesting practical steps for the nuclear weapon states to take to achieve it.

It documents the successes and failures of six decades of attempts to control nuclear weapons proliferation and, within this context, asks the urgent questions that world leaders, politicians, NGOs, and scholars must address in the years ahead.

Abstract

The case studies in this special issue demonstrate that the Obama administration's 2010 Nuclear Posture Review (NPR) and related nuclear policy initiatives encouraged a number of other nuclear weapon states to likewise reduce the role of nuclear weapons in their national security doctrines and helped pave the way with non-nuclear weapon states for a successful 2010 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons. This article reviews the contributing authors' case study findings regarding key foreign governments that applauded the 2010 NPR and were receptive to President Barack Obama's vision of a world free of nuclear weapons as well as governments that remained skeptical about US disarmament and arms control initiatives. We conclude with an analysis of the lessons that should be learned from the 2010 NPR process: the need for consistent implementation of changes in nuclear weapons doctrine, improved coordination and consultation with allies and other states, and further global education about the likelihood and consequences of nuclear terrorism.

By deemphasizing the role of nuclear weapons in US security policy, the 2010 Nuclear Posture Review (NPR) could lead India to slow or halt the growth of its nuclear weapons capabilities and to adopt a less assertive nuclear doctrine; however, the NPR is unlikely to have this effect on India's nuclear program. This is the case for two reasons. First, Indian leaders do not seek to emulate US nuclear behavior; they formulate policy based primarily on their assessment of the security threats facing India. Second, Indians do not think that the NPR augurs major changes in US nuclear policy. Thus, it will not alter the international strategic environment sufficiently to enable India to relax its nuclear posture. In fact, Indian strategists believe that the new US policy fails even to match India's current degree of nuclear restraint. Therefore, according to Indian experts, the NPR will have little impact on India.

Abstract

The 2010 Nuclear Posture Review (NPR) conducted by the United States has become an important element of the US-Russian relationship, for the policies set during the review process directly affect Russian officials' perceptions of their security environment and provide a framework for the domestic debate on security issues. From Moscow's point of view, the most important outcome of the NPR process was the resumption of the bilateral arms control negotiations and the US willingness to work with Russia to resolve the dispute about missile defense. These developments helped strengthen the domestic institutions in Russia that support a cooperative US-Russian agenda, securing Russia's cooperation with the United States on a range of nonproliferation issues. Additionally, the renewed US commitment to nuclear nonproliferation, disarmament, and reduced reliance on nuclear weapons has apparently had an effect on the new Russian military doctrine, which somewhat reduces the role of nuclear weapons in Russian national security policy.

Abstract

The Obama administration has argued that its efforts to reduce the role of nuclear weapons in US defense policy and work toward “a world free of nuclear weapons” will encourage other governments to strengthen the nuclear nonproliferation regime and support global nuclear disarmament. Does the evidence support this assertion? This essay describes the changes in US nuclear weapons and disarmament policies initiated by the Obama administration and outlines four potential pathways through which the United States might influence other governments' policies: by reducing nuclear threat perceptions, by changing global beliefs about what constitutes “responsible” nuclear behavior, by impacting domestic debates about disarmament in foreign capitals, and by creating new diplomatic negotiation dynamics.
