(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 to civilian use after the treaty went into force.


CWC states with declared stockpiles

Of 190 signatory nations to the CWC, state parties listed below have also declared stockpiles, agreed to monitored disposal, and verification, and in some cases, used chemical weapons in conflict. Both military targets and civilian populations have been affected; affected populations were not always damaged collaterally; instead, at times: themselves the target of the attack. , only North Korea and the United States are confirmed to have remaining stockpiles of chemical weapons. *India *Iraq *Japan *Libya *Russia *Syria *United States

Rear Admiral Thomas Brooks cited this evidence in identifying Egypt as a "probable" chemical weapons possessor. More recent analyses are more careful by estimation the current status of 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 as a "probable" chemical weapons possessor in testimony before Congress. Ethiopia has ratified CWC in 1996 and did not declare any offensive CW program. From that time no evidence has been presented to contradict this statement.


India

. India declared a stockpile of 1044 tonnes of sulfur mustard in its possession. In 2005, among the six nations that declared stockpiles of chemical weapons, India was the only one to meet its deadline for chemical weapons destruction and for inspection of its facilities by the OPCW. By the end of 2006, India had destroyed more than 75 percent of its chemical weapons/material stockpile and was granted an extension for destroying the remaining CW until April 2009. It was anticipated that India would achieve 100 percent destruction within that time frame. On May 14, 2009, India informed the United Nations that it had completely destroyed its stockpile of chemical weapons.

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

agreement, the United Nations passed Resolution 687 which established its Special Commission ( UNSCOM). 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 eliminated 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, some 4,000 tons of precursor chemicals, some 980 pieces of key production equipment, and some 300 pieces of analytical equipment. Notwithstanding these extraordinary achievements, there remained important uncertainties regarding Iraq's holdings of chemical weapons, their precursors, and munitions. The Organisation for the Prohibition of Chemical Weapons, which oversees destruction measures, has announced "The government of Iraq has deposited its instrument of 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 Party to the Convention". Iraq has also declared stockpiles of CW, and because of their recent accession is the only State Party exempted from the destruction time-line. On September 7, 2011,

/ref> Assessment of Israeli chemical weapons capabilities are generally redacted from declassified U.S. documents. Although Israel has signed the CWC, it has not ratified the treaty and therefore is not officially bound by its tenets. The country is believed to have a significant stockpile of chemical weapons, likely the most abundant in the Middle-East, according to the Russian Foreign Intelligence Service.

North Korea

North Korea did not sign 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 5000 tons), including blister, nerve, choking, psychoincapacitant, 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 4500 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 (
