The 9/11 terrorist attacks prompted a new urgency in efforts to deal with chemical, biological, radiological and nuclear proliferati on. The potential acquisition and use by terrorist groups of such weaponry was suddenly a much increased threat. The G8 Global Partnership against the Spread of Weapons and Materials of Mass Destruction subsequently encouraged some twenty-two countries and the European Union to pledge up to $20 billion to address this challenge. The creation of the Global Partnership was the first time so many countries agreed to collaborate on a range of non-proliferation, security and nuclear safety programmes, as well as commit such an amount of resources to them. Based on extensive primary research, this Whitehall Paper assesses the success and shortcomings to date of the Global Partnership, and suggests how the mechanism can be bolstered and taken forward.

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.
