Chemical Weapons Banned: Global Disarmament Treaty Takes Effect

The Chemical Weapons Convention entered into force on April 29, 1997, after being signed in 1993 and ratified by 87 nations. The treaty banned the development, production, stockpiling, and use of chemical weapons, and established the Organisation for the Prohibition of Chemical Weapons (OPCW) in The Hague to verify compliance through inspections. By 2023, 193 nations had joined, making it one of the most widely adopted arms control treaties in history. Declared stockpiles from the United States and Russia, totaling over 70,000 tonnes of chemical agents, have been destroyed. However, Syria used sarin and chlorine against civilians during its civil war, and Russia used the nerve agent Novichok in assassination attempts, demonstrating the treaty's enforcement limitations.
