Rising concern over the increasing threat of nuclear war impelled the 2017 United Nations (UN) negotiations and adoption by 122 UN member states of a Treaty on the Prohibition of Nuclear Weapons. The Treaty seeks to ban nuclear weapons globally in the same way chemical and biological weapons have already been prohibited. This book provides the first in-depth comprehensive analysis of the implications and possibilities of the new treaty, drawing on the insights of international relations, international laws, and disarmament experts and specialists from Europe, America, the Asia-Pacific, and the UN. In a context where existing nuclear weapon states have so far declined to be party to the new treaty, the book examines not only its emergence and significance but also the prospects and possibilities for its implementation, the challenges associated with verifying the new agreement, the role of both civil society and governments, and the treaty's wider implications in addressing regional and global nuclear threats. This book was originally published as a special issue of Global Change, Peace & Security but additionally includes the special section articles on the treaty in the Journal for Peace and Nuclear Disarmament.

International efforts to prevent the spread of weapons of mass destruction (WMD)-including nuclear, biological, and chemical weapons-rest upon foundations provided by global treaties such as the Nuclear Non-Proliferation Treaty (NPT) and the Chemical Weapons Convention (CWC). Over time, however, states have created a number of other mechanisms for organizing international cooperation to promote nonproliferation. Examples range from regional efforts to various worldwide export-control regimes and nuclear security summit meetings initiated by U.S. president Barack Obama. Many of these additional nonproliferation arrangements are less formal and have fewer members than the global treaties. International Cooperation on WMD Nonproliferation calls attention to the emergence of international cooperation beyond the core global nonproliferation treaties. The contributors examine why these other cooperative nonproliferation mechanisms have emerged, assess their effectiveness, and ask how well the different pieces of the global nonproliferation regime complex fit together. Collectively, the essayists show that states have added new forms of international cooperation to combat WMD proliferation for multiple reasons, including the need to address new problems and the entrepreneurial activities of key state leaders. Despite the complications created by the existence of so many different cooperative arrangements, this collection shows the world is witnessing a process of building cooperation that is leading to greater levels of activity in support of norms against WMD and terrorism.
