Not many people can say they've held North Korea's plutonium in their hands, but Siegfried Hecker has toured North Korea's nuclear facilities four times. He was the director of the Los Alamos National Laboratory and has advised several U.S. presidents on nuclear security. Hecker tells us about North Korea's weapons capabilities and whether we're heading toward the world's first nuclear war. He is currently a senior fellow at the Freeman Spogli Institute for International Studies.
