Tooele, Utah (CNN) -- Syria has been given a year to eliminate its chemical weapons arsenal, or face the threat of a U.S. military strike. Yet it may come as a surprise that the United States has still not destroyed all of its massive supply of deadly nerve agents. In fact, neither has Russia. Both Washington and Moscow signed the Chemical Weapons Convention of the 1990s, which forbid the use, production and stockpiling of chemical weapons. And both countries missed the convention's extended deadline last year to destroy all of their chemical weapons. This fact was highlighted during Friday's ceremony awarding the 2013 Nobel Peace Prize to the Organisation for the Prohibition of Chemical Weapons, which is helping to eliminate the Syrian army's stockpiles of poison gas.
