The Role of the Chemical Weapons Convention in Countering Chemical Terrorism

A series of incidents over the past two decades has indicated that some terrorist groups are interested in acquiring and using improvised chemical devices (ICDs). Although the 1993 Chemical Weapons Convention (CWC) is a disarmament treaty that is legally binding only on sovereign states that join it voluntarily, the Convention fortuitously includes several provisions that can help its members to prevent chemical terrorism or to manage the consequences of an attack. This article examines the articles of the CWC that are relevant to counterterrorism and discusses how their implementation could be improved at the national and international levels. The article also addresses the role that the CWC secretariat, the Organization for the Prohibition of Chemical Weapons (OPCW) in The Hague, currently plays in preventing and responding to incidents of chemical terrorism, and the political factors that constrain its activities in the counterterrorism field.
