Much progress has been made in recent years to prevent the theft of weapons-useable nuclear material around the world, but some of these materials remain dangerously vulnerable. At a time of rising risk from the self-proclaimed Islamic State and other groups, governments must redouble their efforts to prevent nuclear weapons from getting into the hands of terrorists. Ahead of the upcoming Nuclear Security Summit in Washington, a new report presents a stark choice: will the world recommit to continuous improvement in strengthening nuclear security, or will efforts decline and the danger of nuclear terrorism grow?

Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey of the Harvard Belfer Center’s Project on Managing the Atom launched the new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline? Carnegie’s Toby Dalton moderated.
