Iran suffered severe losses from Iraq’s use of chemical weapons between 1982 and 1988 during the ifmat - chemical weaponsIran-Iraq War. Consequently, Iran has significant experience with the effects of chemical warfare (CW). Iran ratified the Chemical Weapons Convention (CWC) in November 1997 and has been an active participant in the work of the Organisation for the Prohibition of Chemical Weapons (OPCW). Iran has publicly acknowledged the existence of a chemical weapons program developed during the latter stages of the 1980 to 1988 war with Iraq. After ratifying the CWC in 1997, Iran opened its facilities to international inspection and claimed that all its offensive CW activities had been terminated and the facilities destroyed prior to the treaty’s entry into force.Nevertheless, throughout the late 1990s and the early 2000s, the United States claimed that Iran ifmat - chemical weapons1maintained an active program for the development and production of chemical weapons. This program was alleged to include stockpiles of blood, blister, choking, and possibly nerve agents. In its most recent U.S. intelligence report to Congress on the subject, the Director of National Intelligence asserted that Iran “maintains the capability to produce chemical warfare (CW) agents and conducts research that may have offensive applications.”
