When Treaties Work: The Chemical Weapons Convention

The Chemical Weapons Convention (CWC), which prohibits the manufacture, stockpiling, and use of chemical weapons, entered into force in 1997. It is now the most widely adopted international arms control treaty, with 193 states parties.

The CWC is a clear example of a treaty that works. Since its adoption, all declared chemical weapon stockpiles have been destroyed, including those of the United States last year. Its broad acceptance has also reinforced international norms against chemical weapons use. When such weapons were deployed in Syria in 2013, the atrocity prompted Russia and the United States to pressure the Assad regime to join the CWC and allow investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) to oversee the destruction of Syria’s remaining stockpile. This effort earned the OPCW the Nobel Peace Prize that same year.

The CWC is fulfilling its purpose. Joining me to discuss how the treaty was created, its success in shaping state behavior, and what lies ahead now that all declared stockpiles have been eliminated is Paul Walker. He is the chair of the Chemical Weapons Convention Coalition, vice chair of the Arms Control Association, and a former weapons inspector. We begin with the history of efforts to ban chemical weapons before exploring how the CWC has transformed the global approach to these weapons of mass destruction.
