At a conference on nuclear non-proliferation issues hosted by the Carnegie Endowment and broadcast by National Public Radio, two panels of experts discussed current nuclear threats to international security and the past 60 years of nuclear arms control. Among the topics addressed were the need for non-proliferation agreements and enforcement mechanisms for enforcement, threats posed by rogue state and terrorist organizations, United Nations' efforts to curb proliferation, and U.S. foreign policy. Mr. Connan moderated the discussion and later interviewed Mr. McNamara about his experiences.
