The Division of International Security Studies addresses fundamental Wilsonian concerns affecting international order and U.S. national interests through its research, meetings, and publications. The Division focuses on the traditional security agenda in the transformed politico-military context of the post-9/11 era. It sponsors ongoing programmatic activities on the threats posed by terrorism and the proliferation of weapons of mass destruction, as well as on the “nexus” between these twin challenges. The Division also focuses on the new security agenda, whose scope has been broadened to encompass demographic, environmental, developmental, and social challenges. Its work reflects an emphasis on the use of history as a tool of policy analysis and on comparative analysis across geographical and disciplinary boundaries.
