Former U.S. Senator Sam Nunn, co-chairman and CEO of the Nuclear Threat Initiative, and namesake of the Sam Nunn School of International Affairs, was interviewed about the new documentary Nuclear Tipping Point. "As I view the threat, we have a perfect storm. We have weapons of mass destruction-type material spread in at least 40 countries around the globe. We have technological know-how that is spread very wide now. It was formerly thought that only a state could make a bomb; nobody that's informed on the subject believes that any more. We've got an increasing number of terrorists who would not hesitate to use a nuclear weapon if they were able to get one."
