Obama calls for end to nuclear weapons, but U.S. disarmament is slowest since 1980

Speaking from Hiroshima, the site of the first war-time atomic weapon detonation, President Obama on Friday called for the pursuit of "a world without nuclear weapons."

Only a few days prior, his Department of Defense published new data revealing that the government Obama oversees -- a government which manages the second-largest nuclear stockpile in the world -- had dismantled fewer of its nuclear devices than in any year since at least 1980.

Every year, the Department of Defense declassifies data on the size of the country's nuclear stockpile and the number of warheads dismantled. Its most recent data, released this week, shows that the U.S. stockpile numbered 4,571 at the end of 2015, about 15 percent of its size at its peak during the Cold War in 1967. The number of weapons dismantled was 109, the lowest figure since at least 1980.
