In a sealed room behind a gantlet of armed guards and three rows of high barbed wire at the Army’s Pueblo Chemical Depot in Colorado, a team of robotic arms was busily disassembling some of the last of the United States’ vast and ghastly stockpile of chemical weapons. In went artillery shells filled with deadly mustard agent that the Army had been storing for more than 70 years. “That’s the sound of a chemical weapon dying,” said Kingston Reif, who spent years pushing for disarmament outside government and is now the deputy assistant secretary of defense for threat reduction and arms control. The depot near Pueblo destroyed its last weapon in June; the remaining handful at another depot in Kentucky will be destroyed in the next few days. And when they are gone, all of the world’s publicly declared chemical weapons will have been eliminated.
