This seminar is based on a recently published article that reviews the history of the September 22, 1979 double flash recorded by the VELA satellite and concludes that the flash was an Israeli nuclear test assisted by South Africa. The work of a government panel created at the time to determine the cause of the flash is discussed as is the author's own involvement in the issue.

About the speaker:

Leonard Weiss is an affiliated scholar at Stanford University’s Center for International Security and Cooperation (CISAC). He is also a national advisory board member of the Center for Arms control and Non-Proliferation in Washington, DC. He began his professional career as a PhD researcher in mathematical system theory at the Research Institute for Advanced Studies in Baltimore. This was followed by tenured professorships in applied mathematics and electrical engineering at Brown University and the University of Maryland. During this period he published widely in the applied mathematics literature. In 1976 he received a Congressional Science Fellowship that resulted in a career change. For more than two decades he worked for Senator John Glenn as the staff director of both the Senate Subcommittee on Energy and Nuclear Proliferation and the Committee on Governmental Affairs. He was the chief architect of the Nuclear Nonproliferation Act of 1978 and legislation that created the Defense Nuclear Facilities Safety Board. In addition, he led notable investigations of the nuclear programs of India and Pakistan. Since retiring from the Senate staff in 1999, he has published numerous articles on nonproliferation issues for the Bulletin of Atomic Scientists, Arms Control Today, and the Nonproliferation Review. His current research interests include an assessment of the impact on the nonproliferation regime of nuclear trade with non-signers of the Nuclear Nonproliferation Treaty, and more generally the relationship of energy security concerns with nonproliferation.

July 10, 2011 was a milestone in history, marking twenty years since South Africa acceded to the Nuclear Nonproliferation Treaty (NPT).  To this day, South Africa remains the only country to have produced and assembled nuclear weapons and to have later relinquished that arsenal.  Moreover, that denuclearization came without any direct external intervention, and involved opening-up the former top secret program to international scrutiny, voluntarily, beyond that required by the NPT.  While each example of nuclear weapons proliferation has a unique history and basis, South Africa is a particularly instructive exemplar as a result of its unprecedented rollback. That rollback provided sufficient transparency for clear insights into:

1) Why a nation might seek to acquire nuclear weapons,
2) What tactics might a nation employ to conceal the existence of nuclear weapons program under a “Peaceful” nuclear program umbrella,
3) What strategies might a nation consider with respect to the potential use of such weapons, and
4) Why a nation might choose to renounce its nuclear weapons.

This seminar will focus upon a few less reported, but nonetheless salient, aspects of the South African nuclear weapons program pertinent to the monitoring and assessment of the capabilities and intent of other threshold nations whose nuclear programs remain suspect (despite having been repeatedly declared as being solely for only peaceful purposes).  They include object lessons derived from the various efforts that the minority-ruled government of South Africa took to conceal its nuclear program from external discovery, and to ensure sufficient ambiguity to allow that program to progress unabated, despite externally imposed restraints and sanctions, (and only up until termination was self-imposed through internal decision making). The lessons thus learned also provide an objective basis for comparison and assessment of alternative intents represented by the various capabilities, activities, and statements associated with those of contemporary nuclear threshold states exhibiting similar ambiguity.

About the speaker:

Frank Pabian is the Senior Geospatial Information Analyst at the Los Alamos National Laboratory in the Global Security Directorate and a visiting scholar at CISAC. Frank has nearly 40 years in the nuclear nonproliferation and satellite imagery analysis fields including 30 years with US National Laboratories. During 1996-1998, he served as Nuclear Chief Inspector for the United Nation’s International Atomic Energy Agency (IAEA) during ground inspections in Iraq, focusing primarily on equipment/materials “Hide Sites”, and “Capable Sites” that were deemed potentially associated with weapons of mass destruction development and/or production.

His responsibilities at Los Alamos National Laboratory include “Rest-of-World” infrastructure analysis involving the exploitation of all-source information, particularly commercial satellite imagery in combination with openly available geospatial tools for visualization. Frank has published in numerous peer-reviewed scientific journals on the use of commercial satellite imagery for treaty verification and monitoring, and his work has been featured on magazine covers and in textbooks for training in the nonproliferation and intelligence professions. Frank is a recipient of the US Intelligence Community Seal Medallion (gold medal) for “sustained superior performance” for Nuclear Non-Proliferation Treaty verification support to the IAEA during South Africa’s denuclearization, and for associated discoveries derived from original analysis of all-source, including open source, information. Frank is also a “Certified Mapping Scientist, Remote Sensing” with the American Society for Photogrammetry and Remote Sensing (ASP&RS).

The implementation of the New START Treaty is going well and is a testament to the ongoing reset in relations with the Russian Federation.  As one Treaty provides a foundation for the next, the United States believes the vital cooperation will set the stage for further, deeper reductions.  This will not be easy.  The path from Prague was fast and straight and the first tasks along the way were long overdue or clear. Now, the path is moving into uncharted terrain.  The United States is committed to pushing forward with the momentum gained from New START.
