(CWC), which required the destruction of all chemical weapons by 2012. Twelve nations have declared chemical weapons production facilities and six nations have declared stockpiles of chemical weapons. All of the declared production facilities have been destroyed or converted for civilian use after the treaty went into force.


CWC states with declared stockpiles

Of the 193 nations that have signed the CWC, states listed below have also declared stockpiles and agreed to monitored disposal and verification. In some cases, chemical weapons were used in conflict. Both military targets and civilian populations have been affected. , only North Korea is confirmed to have remaining stockpiles of chemical weapons. * Iraq * Japan * Libya * Russia * Syria * United States

Rear Admiral Thomas Brooks cited this evidence in identifying Egypt as a "probable" country to have chemical weapons. Recent analyses are more careful estimating the current status of a chemical weapons program in Egypt. Only one facility has been identified as "likely involved" in the offensive activities. Although the offensive program may be still in existence, it does not seem that Egypt has a considerable stockpile of operational weapons.


Ethiopia

In 1991 Rear Admiral Thomas Brooks identified Ethiopia before the Congress as a "probability" to have chemical weapons possession. Ethiopia did ratify the CWC in 1996 and did not declare an offensive chemical weapons program. Since then, no evidence has been presented to contradict this statement.


India

On January 14, 1993, India became one of the original nations to sign the CWC. India declared its stock of chemical weapons in June 1997 which included 1,044 tonnes of sulfur mustard in its possession. In 2005, of the six nations that declared stockpiles of chemical weapons, India was the only one to meet their deadline for the destruction of chemical weapons and inspection of its facilities by the OPCW. By the end of 2006, India had destroyed more than 75 percent of its chemical weapons and material stockpile. They were granted an extension to destroy the remainder by April 2009. On May 14, 2009, India informed the United Nations that it had completely destroyed its stockpile of chemical weapons.


Iran

Near the end of the

After launching a research effort in the 1970s, Iraq was able to use chemical weapons in their war against Iran and to kill large numbers of their own Kurdish population in the 1980s. On June 28, 1987, in Sardasht, during two separate attacks on four residential areas, an estimated as 10 civilians were killed and 650 civilians injured.

). The UNSCOM was charged with the task of destroying, removing or rendering harmless "all chemical and biological weapons and all stocks of agents and all related subsystems and components and all research, development, support and manufacturing facilities." By the time UNSCOM left Iraq in December 1998, it had destroyed a large portion of Iraq's chemical weapon potential. UNSCOM had overseen the destruction or incapacitation of more than 88,000 filled or unfilled chemical munitions, over 600 tons of weaponized or bulk chemical agents, 4,000 tons of precursor chemicals, 980 pieces of key production equipment and 300 pieces of analytical equipment. Notwithstanding these extraordinary achievements, the uncertainties regarding Iraq's possession of chemical weapons, their precursors and munitions remain. The Organisation for the Prohibition of Chemical Weapons that oversee destruction measures, announced that "The government of Iraq has deposited their accession to the Chemical Weapons Convention with the Secretary General of the United Nations and within 30 days, on 12 February 2009, will become the 186th State to the Convention". Iraq also declared stockpiles of CW. Because of their recent accession, will be the only State Party exempted from the destruction time-line. On September 7, 2011, Hoshyar Zebari entered the OPCW headquarters, becoming the first Iraqi Foreign Minister to officially visit since the country joined the CWC.

Assessment of Israeli chemical weapons capabilities were redacted from declassified U.S. documents. Although Israel did sign the CWC, it has not ratified the treaty and therefore is not officially bound by its provisions. Beliefs are that Israel has a significant stockpile of chemical weapons, likely to be the most abundant in the Middle-East according to the Russian Foreign Intelligence Service. A 1983 CIA report stated that Israel, after "finding itself surrounded by front-line Arab states with budding chemical weapon capabilities, became increasingly conscious of its vulnerability to chemical attack ... undertook a program of chemical warfare preparations in both offensive and protective areas ...

North Korea

North Korea did not sign the CWC and is believed to have maintained an extensive chemical weapons program since the mid-1950s. The program includes research, production, stockpiling and weaponisation of large quantities of chemical agents (perhaps as many as 5,000 tons), including blister, nerve, choking, psychochemical incapacitant, vomiting and riot control agents. Several dozen facilities have been identified as likely involved in the offensive program. The production capability of these facilities is estimated as 4,500 tons of chemical agents per year. North Korean armed forces also have large quantities of delivery systems that could carry chemical warheads, including different artillery systems, aerial bombs, mines, tactical ballistic missiles (

. In 1991, Rear Admiral Thomas Brooks identified Pakistan as a "probable" chemical weapons possessor in testimony before Congress. In 1992, India and Pakistan signed a bilateral arms control treaty of chemical weapons that requires both countries to make a commitment to not develop, possess or use chemical weapons. On January 13, 1993, Pakistan became an original signatory of

(OPCW). Despite its good standing, Pakistan has been accused of covertly running a military chemical weapons program– the accusations were primarily made by India since 1970s. The Indian assertion was said to be primarily based on the import of toxic chemicals and metals and an assumption of absence of their use in the civilian biochemical industry. In 1999, Pakistan, addressing the Indian allegations at the United Nations, announced a mandate and regulation for all domestic chemical producers to "furnish details of the chemicals" imported or used in Pakistan.


Russia

Russia entered the CWC with the largest declared stockpile of chemical weapons in the world. By 2010 the country had destroyed 18,241

Sudan

Some past reports of uncertain credibility indicated that Sudan may have used chemical weapons against the rebels in the southern part of this country. Sudan accessed to CWC in 1999 and did not declare any offensive CW program.

When questioned about the topic, Syrian officials stated that they feel it is an appropriate deterrent against Israel's undeclared nuclear weapons program which they believe exists. On July 23, 2012, the Syrian government acknowledged, for the first time, that it had chemical weapons. Independent assessments indicate that Syria could have produced up to a few hundred tons of chemical agent per year. Syria reportedly manufactures the unitary agents:

United States

The United States has used multiple types of chemical weapons both in war and in testing. For example, testing of how various chemical weapons will disperse in different climates and delivery systems during Operation LAC. Police forces periodically use CS against violent protests domestically, while use and deployment is banned in military use. The United States possessed a stockpile of chemical weapons since World War I. It banned the production or transport of chemical weapons in 1969. The U.S. began chemical weapons disposal and destruction in the 1960s, first by deep-sea burial; by the 1970s, incineration was the primary disposal method used. The use of chemical weapons was officially renounced in 1991, and the U.S. signed the Chemical Weapons Convention in 1993. As of July 7, 2023, the remaining stockpiles of sulfur mustard were announced to be destroyed.Stockpile Destruction Complete
