On the eve of the Nuclear Security Summit in Seoul, South Korea, a new study finds that an international initiative to secure all vulnerable nuclear stockpiles within four years has reduced the dangers they pose. But the new analysis, by researchers in Harvard University’s Project on Managing the Atom, also concludes that much will remain to be done to ensure that all nuclear weapons and material are secure when the current four-year effort comes to an end. “At the end of four years, the global risks of nuclear theft will be significantly lower than they were before,” said co-author Matthew Bunn, associate professor of public policy at Harvard Kennedy School. “But there will still be a great deal left to do to make sure that all the world’s stocks of nuclear weapons and the materials needed to make them are protected from the full range of plausible terrorist and criminal threats – in a way that will last.” The other co-authors of the report are Martin B. Malin, executive director of the Project on Managing the Atom in the Kennedy School’s Belfer Center for Science and International Affairs, and Eben Harrell, research associate in the Managing the Atom project. The study, “Progress on Securing Nuclear Weapons and Materials: the Four-Year Effort and Beyond,” was released in advance of the Seoul summit on March 26-27, 2012, being attended by leaders or senior officials from 54 countries and four international organizations.
