In this episode of Intelligence Matters, host Michael Morell speaks with Laura Holgate, former U.S. Ambassador to the International Atomic Energy Agency and Senior Director for Weapons of Mass Destruction Terrorism and Threat Reduction on President Obama's National Security Council. Holgate, now vice president for materials risk management at the Nuclear Threat Initiative, explains the threats posed by chemical, biological, radiological and nuclear weapons and how the United States, along with international partners, works to contain them. Holgate and Morell assess the United States' approach to some of the most precarious proliferation challenges in the world, including from North Korea, Iran and, more recently, Saudi Arabia.
