Senate Republican leader Mitch McConnell announced Friday that the U.S. has destroyed the last of its declared chemical weapons stockpile, a milestone in the history of warfare dating back to World War I.
McConnell said in a statement that workers at Kentucky’s Blue Grass Army Depot eliminated the last of thousands of rockets filled with GB nerve agent that are the last of the United States’ declared chemical weapons and completed a decadeslong campaign to eliminate a stockpile that by the end of the Cold War totaled more than 30,000 tons.
