"A Call for German Leadership in Combating Nuclear Terrorism"
Op-Ed
By Rolf Mowatt-Larssen, Senior Fellow, Belfer Center for Science and International Affairs and Tom Bielefeld, Associate, Project on Managing the Atom
"...Germany has an opportunity at the Washington summit — and thereafter — to step up and lend non-American leadership to the problem. Recognizing that in many of the world's capitals the threat of nuclear terrorism is not yet being taken seriously, and when in some of them the very notion is even considered an American pretext for an entirely different, potentially hostile political agenda, non-American leadership is most urgently needed."

"Nuclear Forensics and Its Role in Security Policy"
Presentation
By Tom Bielefeld, Associate, Project on Managing the Atom
Nuclear forensic analysis is currently discussed as a potentially important new tool to prevent nuclear terrorism by enabling investigators to attribute nuclear materials to their production facility and thus deterring potential state actors from transferring such materials to terrorists. In the seminar, an introduction into the technical possibilities and limitations of pre- and post-attack nuclear forensics will be given, based entirely on open source analysis. This will be followed by a discussion about the roles that nuclear attribution can — or cannot — play in security policy.
