The overall classification of the symposium will be SECRET//REL FVEY, FRA. . Symposium registration is limited to personnel from Australia, Canada, New Zealand, the United Kingdom, the United States, and France who possess the requisite security clearance. This year’s symposium marks a quarter-century since the launch of the Defense Counterproliferation Initiative (DCI) and will focus on the threats, challenges and opportunities ahead of us. The DCI guided the U.S. Department of Defense in confronting new WMD dangers posed by rogue states and terrorists in the post-Cold War world, but great power competition once again looms large among WMD challenges even as rogue state and terrorist threats remain. At the symposium, senior officials and experts will discuss choices made and current choices before the United States, allies and partners in this changing world on nuclear weapons policy and posture, arms control and nonproliferation, biodefense, emerging technologies, and requirements, plans, concepts and capabilities for countering WMD.
