During the Cold War the United States and the Soviet Union made launch-on-warning an important part of their nuclear strategies. To achieve the launch-on-warning capability both countries deployed networks of early-warning satellites and radars as well as command and control systems that allowed them to launch a retaliatory strike in response to a ballistic missile attack. These systems, which remain operational to this day, are believed to support the "hair-trigger alert" posture of strategic nuclear forces.

This presentation will consider the current status of the U.S. and Russian early-warning systems and the extent to which characteristics of these systems can contribute to the danger of an accidental ballistic missile launch. It will also analyze various proposals that aim at reducing the danger of accidental launch--de-alerting, reduction of strategic forces, repairing the Russian early-warning system, etc. It will be shown that most of these measures are inadequate and some may in fact increase the danger of an accident.

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, 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.

How have curators responded to the 1995 controversy over the National Air and Space Museum's Enola Gay exhibit? Trends in curatorial practice since then offer opportunities for museum professionals who wish to question the costs of wars. Curators now believe that museum exhibits should be open-ended and also should reflect a multiplicity of views about a given subject. Their main strategy is to evoke a variety of memories among museum goers without trying to integrate them completely - collecting memories rather than collectivizing them. Far more challenging for museums is representing the larger social categories that shape peacetime lives as well. They have greatest difficulty with representing the experiences of foreigners. Yet, many Americans have never been comfortable with the official A-bomb narrative. If, as museum professionals now emphasize, visitors are bringing their own meaning to exhibits, display of the Enola Gay will forever provide an invitation to debate the moral and strategic legitimacy of the use of the atomic bomb in August 1945.

Laura Hein specializes in the history of Japan in the 20th century and its international relations. She is author of Reasonable Men, Powerful Words: Political Culture and Expertise in Twentieth Century Japan (University of California Press, 2004), which explores various ways in which economic expertise intersected with politics through a study of the lives of a tight-knit group of Japanese intellectuals. She also has a strong interest in problems of remembrance and public memory, resulting in three co-edited books with Mark Selden: Living with the Bomb: American and Japanese Cultural Conflicts in the Nuclear Age (1997), Censoring History: Citizenship and Memory in Japan, Germany, and the United States (2000), and Islands of Discontent: Okinawan Responses to American and Japanese Power (2003). She received her Ph.D. from the University of Wisconsin.

Zia Mian, a research assistant with the Program on Science and Global Security (PS&GS) at Princeton University and lecturer of public and international affairs at the Woodrow Wilson School, has been with PS&GS since 1997. His interests include nuclear weapons and nuclear energy programs in South Asia, and finding alternative policies that can contribute to disarmament and sustainable development. With Dr. Pervez Hoodbhoy, Mian co-produced Crossing the Lines, a documentary film about India, Pakistan, and the battle over Kashmir, which was shown at CISAC this past summer. He has edited and co-edited a number of books on South Asia, including Out of the Nuclear Shadow (co-edited with Smitu Kothari; Zed Press, London and Rainbow Press, New Delhi, 2001). Mian has also co-edited a volume with Iftikhar Ahmad and Dohra Ahmad, Between Past and Future: Selected Essays on Pakistan by Eqbal Ahmad (Oxford University Press, Karachi).
