Preventive Defense Project

The Preventive Defense Project (PDP) is a research collaboration of Stanford University and Harvard University's Kennedy School of Government, co-directed by William J. Perry and Ashton B. Carter. The Project focuses on key problems of national and international security with the aim of preventing possible threats from becoming actual threats. The Project promotes the concept of preventive defense as critical to the formulation of American defense strategy in the post-Cold War era, where, in the absence of an imminent, major, traditional military threat to American security, today's leaders are presented with a unique challenge and opportunity to prevent future Cold War-scale threats to international security from emerging.
