Science, Technology, and Public Policy

In the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.

The recent publications on WikiLeaks reveal a story about money, fame, sex, underground hackers, and betrayal. But it also involves fundamental questions regarding cyber-security and foreign policy. This paper argues WikiLeaks is only the symptom of a new, larger problem which is the result of technological advances that allow a large quantity of data to be 'stolen' at low or no cost by one or more individuals and to be potentially made public and to go 'viral', spreading exponentially online.

Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years, but the factors that drive and/or constrain nuclear security changes are not well understood. Matthew Bunn and Eben Harrell surveyed nuclear security professionals in countries with nuclear weapons, HEU, or separated plutonium to explore this issue. This paper describes the survey, its results, and implications for strengthening global nuclear security.
