"Nuclear proliferation is a crime that pays well. Those involved in the Khan network were made very wealthy for their efforts, and the inability of the international community to effectively punish them has resulted in a missed opportunity to provide a deterrent against future black-market salesmen."

Nuclear waste has long been seen mostly as an environmental issue — but it's a critical global security issue too. Plutonium has been created only twice on earth. After the Gabon mines reaction, the next significant batch of plutonium arrived 2 billion years later in U.S. labs; it destroyed Nagasaki. Let's bury our nuclear waste — and, if necessary, nuclear waste from other countries — before it has the chance to bury us.

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.
