Eben Harrell and David Hoffman discuss their project: "Kazakhstan: Degelen Mountain and a Nuclear Threat Averted." Harrell traveled to Kazakhstan to witness the completion of a U.S. top-secret, $150 million project in cooperation with Russia and Kazakhstan to make sure leftover plutonium from the Cold War would never fall into the hands of terrorists. Hoffman met with senior U.S. scientists to bring details of the remarkable anti-terrorism operation to light.
