The articles contained in this volume encapsulate the current debate on why and how to move towards a world free of nuclear weapons. Presented at an international conference held in New Delhi, the papers by leading experts from around the world, question existing paradigms and explore new security architectures.

On November 10, 2017, Pope Francis became the first pontiff in the nuclear era to take a complete stand against nuclear weapons, even as a form of deterrence. At a Vatican conference of leaders in the field of disarmament, he made it clear that the possession of the bomb itself was immoral. A World Free from Nuclear Weapons presents the pope’s address and original testimony from Nobel Peace Prize laureates, religious leaders, diplomats, and civil society activists. These luminaries, which include the pope and a Hiroshima survivor, make the moral case against possessing, manufacturing, and deploying nuclear arms. Drew Christiansen, a member of the Holy See delegation to the 2017 United Nations conference that negotiated the Treaty to Prohibit Nuclear Weapons, helps readers to understand this conference in its historical context. A World Free from Nuclear Weapons is a critical companion for scholars of modern Catholicism, moral theology, and peace studies, as well as policymakers working on effective disarmament. It shows how the Church’s revised position presents an opportunity for global leaders to connect disarmament to larger movements for peace, pointing toward future action.

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.

This volume features a selection of the best scholarship on international law as it is relevant to the proliferation of weapons of mass destruction. The essays consider the nonproliferation legal regime as a normative system and offer a more discrete consideration of international law in each weapons of mass destruction technology area. The role, authority and track record of the UN Security Council in this area are also evaluated.

This open access book examines key aspects of international cooperation to enhance nuclear safety, security, safeguards, and nonproliferation, thereby assisting in development and maintenance of the verification regime and fostering progress toward a nuclear weapon-free world. Current challenges are discussed and attempts made to identify possible solutions and future improvements, considering scientific developments that have the potential to increase the effectiveness of implementation of international regimes, particularly in critical areas, technology foresight, and the ongoing evaluation of current capabilities.
