Ambassador Douglas Lute, former ambassador to the North Atlantic Council, NATO's principal decision-making body, spoke at the Future of Diplomacy project on NATO's role today, adapting to current threats, and Russia's relationship with NATO and its member States.

As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security.

Ukraine-based journalist Maxim Tucker has just published two articles to claim that pro-Russian rebels in Eastern Ukraine are plotting to manufacture a dirty bomb with the help of Russian scientists, using radioactive waste from a storage facility at the Donetsk Chemical Factory.

Hans Kristensen at the Federation of American Scientists recently wrote an interesting piece about two men who were arrested for allegedly planning an attack on an Italian military base that stores U.S. nuclear weapons. You can read his full account here.

Republicans and Democrats alike have traditionally understood that investing in nuclear security is a small price to pay compared with the devastating economic, political and social costs of nuclear terrorism. That’s why U.S. cooperation with Russia and other countries to secure vulnerable nuclear material has enjoyed bipartisan support.

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.

As the Crimea crisis continues, the Bulletin of the Atomic Scientists asked a number of experts about what an appropriate short-term U.S. response to the crisis would entail, as well as how the crisis will affect U.S. policy towards Russia. Belfer Center Director Graham Allison was among those that participated.

Associate Professor of Public Policy and Project on Managing the Atom Co-Principal Investigator Matthew Bunn provides a comprehensive assessment of global efforts to secure and consolidate nuclear stockpiles, and a detailed action plan for securing all nuclear materials in four years.  Securing the Bomb 2010 was commissioned by the Nuclear Threat Initiative (NTI). The full report, with additional information on the threat of nuclear terrorism, is available for download on the NTI website.

Urgent actions are needed to prevent a nuclear or radiological 9/11.  Terrorists are actively seeking nuclear weapons and Radiological Dispersal Devices (RDDs) and the materials to make them.  There are scores of sites where the essential ingredients of nuclear weapons exist, in dozens of countries worldwide.  There are thousands of sites worldwide where radiological materials exist.  Many of these sites are not sufficiently secured to defeat the kinds of threats that terrorists and criminals have demonstrated they can pose.  A dangerous gap remains between the urgency of the threat of nuclear and radiological terrorism and the scope and pace of the U.S. and world response.  While the gap has narrowed significantly in recent years, much more needs to be done.  This paper describes the nuclear and radiological terrorism threats, analyzes the actions taken so far to address these threats, and recommends further actions going forward.
