When the Soviet Union dissolved on Dec. 25, 1991, the nuclear threat changed from the Cold War concern of ending civilization as we know it to one of securing "loose nukes" in chaotic Russia and other states of the former Soviet Union. I had the opportunity to visit the secret cities of the Russian nuclear complex six weeks after the collapse and to initiate a program of scientific collaboration between U.S. and Russian nuclear scientists. Together, we made remarkable progress in reducing the threat in the early and mid-1990's because of the trust we were able to build based on mutual respect, similar objectives, and a common heritage in the great early-20th century school of European physics.

Although the number of joint U.S. - Russian cooperative threat reduction programs increased and the U.S. funding rose dramatically at the turn of the millennium, real progress slowed as U.S. and Russian objectives began to diverge, and the programs became politicized and bureaucratized. Major opportunities to reduce the long-term threat were lost. Cooperation was re-energized by the tragic events of 9/11 and the emerging threat of nuclear terrorism. Today, both Presidents Bush and Putin agree that keeping nuclear weapons out of the hands of terrorists is their highest security priority. Yet, strategy and commitment on both sides appear incommensurate with the threat. I will discuss critical barriers to and opportunities for renewed cooperation to meet the threat.

On November 15, 2005, the Canadian Nuclear Waste Management Organization (NWMO) is required by law to submit a recommendation to the parliament on how Canada should manage its spent nuclear reactor fuel. NWMO, which came into existence on November 15, 2002, is undertaking a creative and iterative process engaging the technical, political, and public communities in arriving at their recommendation. As an integral part of the process, NWMO established an assessment team to develop an analytical framework and a systematic method for evaluating and comparing options. Isaacs, one of two non-Canadian members of the team, will describe the ongoing work with emphasis on the multi-attribute utility analysis that was developed to evaluate the options against a range of technical, economic, and social issues.

Tom Isaacs directs the policy and planning activities of the Lawrence Livermore National Laboratory. He is a member of advisory committees for Oregon State University and Texas A&M University nuclear engineering departments.

Isaacs was a member of the National Research Council committee that produced "One Step at a Time: The Staged Development of Geologic Repositories for High-Level Radioactive Waste," and was a member of the NRC Committee on Building a Long-Term Environmental Quality Research and Development Program in the U.S. Department of Energy.

He was chairman of the Expert Group on Nuclear Education and Training, a 17-nation evaluation sponsored by the Nuclear Energy Agency in Paris. He served on the DOE Science Advisory Committee for Environmental Management. He was a member of the "Blue-Ribbon Panel" on the Future of University Nuclear Engineering Programs and University Research and Training Reactors for the Department of Energy.

Previously, Isaacs was the Executive Director of the advisory committee to the Secretary of Energy and the White House which made recommendations on the need for nuclear regulatory reform in the DOE. He also held several management positions in the High-Level Radioactive Waste Program of the DOE, including Director of Strategic Planning and International Programs, Director of Policy and External Relations, and Deputy Director of the Office of Geologic Repositories. He managed the multi-attribute utility analysis that underpinned the selection of Yucca Mountain as the U.S. repository site.

Isaacs also managed the international technical cooperative program with several European nations and Canada. He was the lead U.S. delegate to the Nuclear Energy Agency's Radioactive Waste Management Committee in Paris and represented the Department with the National Academy of Sciences.

Earlier, Isaacs was Deputy Director of the DOE Office of Safeguards and Security with responsibility for national policy formulation and technical leadership in federal actions to minimize prospects of nuclear proliferation, including establishing the program of technical assistance to the International Atomic Energy Agency for safeguarding nuclear facilities worldwide. He began his career with the U.S. Atomic Energy Commission where he helped oversee the design of the reactor core of the Fast Flux Test Facility (FFTF).

Isaacs graduated with a BS degree in chemical engineering from the University of Pennsylvania, and was a member of the Tau Beta Pi National Engineering Honor Society. He received an MS in engineering and applied physics from Harvard University.

Ambassador Dobbins will review the American and United Nation's experience with nation building over the past sixty years and explore lessons for Iraq, Afghanistan and beyond. He will draw upon the just completed RAND History of Nation Building, the first volume of which deals with U.S. led missions from Germany to Iraq. The newly released second volume covers U.N.-led operations beginning with the Belgian Congo in the early 1960's. Dobbins will compare the U.S. and U.N. approaches to nation building, and evaluate their respective success rates.

Ambassador Dobbins directs RAND's International Security and Defense Policy Center. He has held State Department and White House posts including Assistant Secretary of State for Europe, Special Assistant to the President for the Western Hemisphere, Special Adviser to the President and Secretary of State for the Balkans, and Ambassador to the European Community. He has handled a variety of crisis management assignments as the Clinton Administration's special envoy for Somalia, Haiti, Bosnia, and Kosovo, and the Bush Administration's first special envoy for Afghanistan. He is principal author of the two-volume RAND History of Nation Building.

In the wake of Sept 11, 2001, Dobbins was designated as the Bush Administration's representative to the Afghan opposition. Dobbins helped organize and then represented the U.S. at the Bonn Conference where a new Afghan government was formed. On Dec. 16, 2001, he raised the flag over the newly reopened U.S. Embassy.

Earlier in his State Department career Dobbins served twice as Deputy Assistant Secretary of State for Europe, as Deputy Chief of Mission in Germany, and as Acting Assistant Secretary for Europe.

Dobbins graduated from the Georgetown School of Foreign Service and served 3 years in the Navy. He is married to Toril Kleivdal, and has two sons.

Since Vietnam, the US Army has focused an unprecedented degree of effort on capturing lessons learned in training and on the battlefield and communicating them to other affected units. The Center for Army Lessons Learned (CALL), established after Operation URGENT FURY, is the prime example of the Army's efforts to institutionalize the process of learning during the Cold War. CALL continues to function and provide lessons learned in the current Global War on Terror, while other grassroots organizations have sprung up within the Army to target the learning needs of specific segments of the force. One such organization is CompanyCommand.com, an online professional forum of Army leaders dedicated to outstanding leadership at the small-unit level. This talk will discuss the evolution of organizational learning in the Army since Vietnam, and examine how organizations like CALL and CompanyCommand complement one other in the pursuit of excellence.
