Abstract:  Scholars and policy-makers, when seeking to predict the future of nuclear proliferation, often refer to "nuclear capable states," or "latent nuclear weapons states," or "virtual nuclear powers."  There is consensus, however, about what such terms mean or how to measure a state's "nuclear latency," a condition that leads to widespread miscommunication and misunderstanding in the field.  This talk reviews alternative methods for measuring "nuclear latency" in the political science and technical literatures. It provides historical evidence of the wide range of time-lines for different states to move from one state of nuclear weapons development to more advanced states of development and identifies a set of political factors (including organizational competency, ambivalent political leadership, different arsenal size ambitions) that can influence the time-lags that states experience in their nuclear weapons programs. 

Scott Sagan is a professor of political science and co-director of Stanford's Center for International Security and Cooperation. He is on sabbatical in 2008-09. Before joining the Stanford faculty, Sagan was a lecturer in the Department of Government at Harvard University and served as a special assistant to the director of the Organization of the Joint Chiefs of Staff in the Pentagon. He has also served as a consultant to the office of the Secretary of Defense and at the Sandia National Laboratory and the Los Alamos National Laboratory.

Sagan is the author of Moving Targets: Nuclear Strategy and National Security (Princeton University Press, 1989), The Limits of Safety: Organizations, Accidents, and Nuclear Weapons(Princeton University Press, 1993), and with co-author Kenneth N. Waltz, The Spread of Nuclear Weapons: A Debate Renewed (W.W. Norton, 2002). He is the co-editor of Peter R. Lavoy, Scott D. Sagan, and James L. Wirtz, Planning the Unthinkable (Cornell University Press, 2000). Sagan was the recipient of Stanford University's 1996 Hoagland Prize for Undergraduate Teaching and the 1998 Dean's Award for Distinguished Teaching. As part of CISAC's mission of training the next generation of security specialists he and Stephen Stedman founded Stanford's Interschool Honors Program in International Security Studies in 2000.

His recent articles include "How to Keep the Bomb From Iran," in Foreign Affairs (September-October 2006); "The Madman Nuclear Alert: Secrecy, Signaling, and Safety in October 1969" co-written by Jeremi Suri and published in International Security in spring 2003; and "The Problem of Redundancy Problem: Will More Nuclear Security Forces Produce More Nuclear Security?" published in Risk Analysis in 2004. The first piece warns against "proliferation fatalism" and "deterrence optimism" to argue that the United States should work to prevent Iran's pursuit of nuclear weapons by addressing the security concerns that are likely motivators for Iran's nuclear ambitions. The International Security piece looks into the events surrounding a secret nuclear alert ordered by President Nixon to determine how effective the alert was at achieving the president's goal of forcing negotiations for the end of the Vietnam War. It also questions many of the assumptions made about nuclear signaling and discusses the dangers of new nuclear powers using this technique. Sagan's article on redundancy in Risk Analysis won Columbia University's Institute for War and Peace Studies 2003 Best Paper in Political Violence prize. In this article, Sagan looks at how we should think about nuclear security and the emerging terrorist threat, specifically whether more nuclear facility security personnel increases our safety. His article, "Realism, Ethics, and Weapons of Mass Destruction" appears in Ethics and Weapons of Mass Destruction: Religious and Secular Perspectives, edited by Sohail Hashmi and Steven Lee. In addition to these works, Sagan is also finishing a collection of essays for a book tentatively entitled Inside Nuclear South Asia.

Abstract: In this age of increasing "Global Transparency," commercial satellite imagery has now made it possible for anyone to remotely peer "over the fence" and view what heretofore had been otherwise impossible...clandestine nuclear facilities (most significantly, those capable of producing fissile material suitable for use in nuclear weapons). The synergistic combination of readily available tools: personal computers, the internet, three-dimensional virtual globe visualization applications such as Google Earth, and high resolution commercial satellite imagery has gone beyond what anyone could have imaged just a few years ago. The downside of all this is that those who want to keep their clandestine nuclear facilities and associated activities from being either detected, identified, and/or monitored, are becoming more adept in their use of camouflage, concealment, and deception.

Iran is one such case where it has followed a steep learning curve of adapting to the threat that overhead observation can pose. After repeated dissident group revelations about Iran's clandestine nuclear facilities, together with confirming media broadcast of commercial satellite images of those facilities followed by verification inspections by the International Atomic Energy Agency (IAEA); the government of Iran has become increasingly aware of this threat and gone to greater and greater lengths to try and defeat it. Iran's cover-up tactics have improved with time...from concealed infrastructure and false cover stories (Natanz)...to refurbishment and sanitization of facilities following removal of incriminating equipment (Kalaye Electric and Lashkar Abad), to the wholesale razing of facilities together with the removal of dirt and vegetation to defeat IAEA forensic environmental sampling (Lavizan).

While the international community continues to debate the issue of whether or not Iran's nuclear program is purely peaceful in nature (helping it to stay an "open case"), Iran is defiantly pursuing its goal of fissile material production. Syria, on the other hand (evidently together with North Korea), was also quite aware of the overhead observation threat, taking great pains to conceal its plutonium production reactor at Al-Kibar. Syria disguised the true function of the facility by employing minimal site security (no fences or guard towers), having minimal support infrastructure (with non visible powerlines and only buried water lines), not installing a telltale reactor ventilation stack or cooling tower, hiding the reactor building in a ravine (terrain masking), and finally camouflaging the facility with a false façade to make it appear as a byzantine fortress. Nonetheless, despite all those steps, a leak of ground-level reactor construction and interior photographs, which formed the basis for the subsequent bombing of the facility by Israel, successfully thwarted that effort (the "closed case?"). Rather than confessing the truth about al-Kibar, the Syrian government rushed to remove all traces of the destroyed reactor and supplant it with a new larger footprint building for as yet unknown purposes while continuing to claim it was previously only a disused military warehouse. The IAEA asked d Syria for permission to inspect not only the Al-Kibar site, but reportedly up to three other sites thought to be associated with it. The Syrians refused access to all but the now heavily sanitized Al-Kibar location. We must now all await the IAEA report on the findings of that singular onsite inspection.

In December 2002, Frank served as one of the first US nuclear inspectors back in Iraq with UN/IAEA. While at Los Alamos, Frank has developed and presented commercial satellite imagery based briefings on foreign clandestine nuclear facilities to the International Nuclear Suppliers Group, the IAEA, NATO, and the Foreign Ministries of China and India on behalf of the NNSA and STATE.

Abstract:  Russia is the country that has the largest amount of weapon-usable fissile materials in its disposal, most of which has been produced during the cold war. In the years following the end of the cold war. Russia has undertaken significant effort to downsize its nuclear complex, leading to its serious transformation. This transformation, however, left the basic structure of the nuclear industry, most of the production facilities and most of the fissile material intact. Substantial amounts of weapon-usable fissile materials are still in storage, moved from one facility to another, or used for research and other purposes, creating security risks. Although the dangers associated with continuing presence of weapon material are generally acknowledged, the task of reducing this danger, by either eliminating the material or removing it from circulation and consolidating in a mall number of safe and secure storage sites, has proven difficult. The talk analyses the progress that Russia has made so far in consolidating its weapon-usable materials and describes the challenges that it is facing in further advancing this goal.
