During the strategic modernization program that the Soviet Union undertook in the 1970s, it deployed a large number of multiple-warhead ballistic missiles. This deployment raised concerns in the United States about vulnerability of its land-based missile force and was one of the factors that contributed to the military buildup that the United States undertook in the late 1970s-early 1980s. The newly available documents that contain evidence of the Soviet missile programs demonstrate that the "window of vulnerability" did not exist and provide some insight into the Soviet modernization program.

Pavel Podvig joined CISAC as a research associate in 2004. Before that he was a researcher at the Center for Arms Control, Energy and Environmental Studies at the Moscow Institute of Physics and Technology (MIPT). He worked as a visiting researcher with the Security Studies Program at MIT and with the Program on Science and Global Security at Princeton University, and he taught physics in MIPT's General Physics Department for more than ten years.

Podvig graduated with honors from the Moscow Institute of Physics and Technology in 1988, with a degree in physics. In 2004 he received a PhD in political science from the Moscow Institute of World Economy and International Relations.

His research has focused on technical and political issues of missile defense, space security, U.S.-Russian relations, structure and capabilities of the Russian strategic forces, and nuclear nonproliferation. He was the head of the Russian Strategic Nuclear Forces research project and the editor of a book of the same title, which is considered a definitive source of information on Russian strategic forces.

Sonja Schmid (speaker) is a social science research associate at Stanford University. Having received her Ph.D. in Science & Technology Studies from Cornell University, she is now a science fellow at the Center for International Security and Cooperation, and affiliated with the Program in Science, Technology and Society at Stanford. Her research has focused on understanding complex decision-making processes at the interface between science, technology, and the state in the Cold War Soviet context, and is based on extensive archival research and narrative interviews with nuclear energy specialists in Russia. She is currently working on a book about reactor design choices and the development of the civilian nuclear industry in the Soviet Union. In addition, she is involved in an international research project on Cold War Technopolitics and Colonialism, where she works on Soviet technology transfer to Central and Eastern Europe. Her research interests also include risk communication, and the popularization of science and technology, subjects on which she has published in the past.

Rebecca Slayton (respondent) is a lecturer in the Science, Technology and Society Program at Stanford University and a CISAC affiliate. In 2004-2005 she was a CISAC science fellow. Her research examines how technical judgments are generated, taken up, and given significance in international security contexts. She is currently working on a book which uses the history of the U.S. ballistic missile defense program to study the relationships between and among technology, expertise, and the media. Portions of this work have been published in journals such as History and Technology and have been presented at academic conferences. As a postdoctoral fellow in the Science, Technology, and Society Program at the Massachusetts Institute of Technology, she recently completed an NSF-funded project entitled Public Science: Discourse about the Strategic Defense Initiative, 1983-1988. As a physical chemist, she developed ultrafast laser experiments in condensed matter systems and published several articles in physics journals. She also received the AAAS Mass Media Science and Engineering Fellowship in 2000, and has worked as a science journalist for a daily paper and for Physical Review Focus. She earned her doctorate in chemistry from Harvard University in 2002.

Carol Atkinson (speaker) retired as a lieutenant colonel from the U.S. Air Force in 2005. While in the military she served in a wide variety of management and operational positions in the fields of intelligence, targeting, and combat assessment. During the Cold War she flew on the Strategic Air Command's nuclear airborne command post as a target analyst. During Operation Desert Storm (1991) she worked on the intelligence staff in Riyadh, and, subsequently, on the contingency planning staff in Dhahran/Khobar, Saudi Arabia. While in the military, she taught at the Air Force Academy and the Air Force's Command and Staff College.

Atkinson holds a PhD in international relations from Duke University, an MA in geography from Indiana University, and a BS from the United States Air Force Academy (5th class with women). She is currently a post-doctoral research fellow at the Center for International Studies at the University of Southern California. Atkinson's primary research focuses on U.S. military-to-military contacts as channels of international norm diffusion. She is also working on a project examining the influence of educational exchange programs on democratization and a project on the social construction of the biological warfare threat in the United States.

Jessica Weeks (respondent) is a doctoral candidate in the Stanford Department of Political Science. Her research interests include foreign policy decision-making in non-democratic regimes, the settlement of military crises, and the effects of foreign military interventions on target states. She will be a pre-doctoral fellow at CISAC during 2007-2008. Jessica received her BA in political science from The Ohio State University, and an MA in international history and politics from the Graduate Institute of International Studies in Geneva, Switzerland.

Charles Perrow (speaker) is an emeritus professor of sociology at Yale University and a visiting scholar at CISAC. An organizational theorist, his latest research is presented in The Next Catastrophe: Reducing Our Vulnerabilities to Natural, Industrial, and Terrorist Disasters (Princeton, spring 2007). Among his award-winning research is Organizing America: Wealth, Power, and the Origins of American Capitalism (Princeton, 2002), winner of the Max Weber award for best book on organizations from the American Sociological Association in 2003. His recent articles include "Organizational or Executive Failures?" and "Inside the Nuclear Plant's Executive Office," both published in Contemporary Sociology. Perrow currently serves on a National Academy of Science panel on the possibilities of certifying software. He received his BA, MA, and PhD from the University of California, Berkeley, all in sociology.

Peter G. Neumann (respondent) has been in SRI's Computer Science Lab since September 1971. He is concerned with computer systems and networks, trustworthiness/dependability, high assurance, security, reliability, survivability, safety, and many risks-related issues such as voting-system integrity, crypto policy, social implications, and human needs including privacy. He moderates the Association for Computing Machinery's Risks Forum, edits Communications of the ACM's monthly Inside Risks column, chairs the ACM Committee on Computers and Public Policy, and chairs the National Committee for Voting Integrity. He is a Fellow of the ACM, the Institute of Electrical and Electronics Engineers, and the American Association for the Advancement of Science, and is also an SRI Fellow. He received the National Computer System Security Award in 2002 and the ACM SIGSAC (Special Interest Group on Security, Audit, and Control) Outstanding Contributions Award in 2005. He is a member of the U.S. Government Accountability Office Executive Council on Information Management and Technology, and the California Office of Privacy Protection advisory council.
