US to destroy its largest remaining chemical weapons cache
None
The United States is about to begin destroying its largest remaining stockpile of chemical weapons, marking a milestone in the global campaign to eradicate a debilitating weapon. The Pueblo Chemical Depot in southern Colorado plans to start neutralizing 2,600 tons of aging mustard agent in March.
It's part of the long-running US effort to comply with a 1997 treaty banning all chemical weapons.
