U.S. eliminates last of its chemical weapons stockpile, ending decades-long disarmament effort

The U.S. destroyed its final declared chemical weapon filled with sarin nerve agent in Kentucky.
The U.S. chemical weapons stockpile reached 30,000 tons at its peak before disarmament efforts began.
Congress ordered the elimination of U.S. chemical weapons in 1986 and the U.S. joined the Chemical Weapons Convention in 1997.
The U.S. was the last country to reportedly finish destroying its chemical weapons stocks out of participating nations.
While the U.S. has eliminated its chemical weapons, concerns remain that Russia and China still have undeclared stockpiles.
