Siegfried Hecker testified April 30, 2008, about the importance of expanding the cooperative threat reduction programs to counter the growing proliferation of nuclear weapons and weapons capability. A formal written statement is also available: Hearing of the United States Senate Committee on Appropriations, Subcommittee on Energy and Water Development

Thank you Chairman Dorgan, Senator Domenici and distinguished members of the Committee for giving me the opportunity to comment on the National Nuclear Security Administration's Defense Nuclear Nonproliferation programs and its 2009 budget request. I have a written statement that I would like to submit for the record.

This morning I will summarize the three main points in my statement. My opinions have been shaped by 34 years at the Los Alamos National Laboratory and nearly 20 years of practicing nonproliferation with my feet on the ground in places like Russia, China, India, North Korea and Kazakhstan.  Much of this I have done with the strong support and encouragement of Senator Domenici.

1) The proliferation of nuclear weapons and weapons capability is growing. Today, we face a nuclear threat in North Korea, nuclear ambitions in Iran, a nuclear puzzle in Syria, recently nuclear-armed states in Pakistan and India, and an improved, but not satisfactory, nuclear security situation in Russia and other states of the former Soviet Union. The danger of nuclear terrorism is real. This is not a fight the United States can win alone. We cannot simply push the dangers beyond our borders. It is imperative to forge effective global partnerships to combat the threat of nuclear terrorism and the proliferation of nuclear weapons. Meeting these challenges requires diplomatic initiative and technical cooperation. The United States must lead international diplomacy and DOE/NNSA must provide technical leadership and capabilities. The NNSA has done a commendable job in nuclear threat reduction and combating nuclear proliferation. However, funds to support these activities are not commensurate with the magnitude or the urgency of the threat.

2) CTR began with Nunn-Lugar followed by Nunn-Lugar-Domenici legislation directed at the aftermath of the breakup of the Soviet Union. We must stay engaged with Russia and the other states of the Soviet Union. Much progress has been made, but more needs to be done. We have to change the nature of the partnership to one in which Russia carries more of the burden.

We should expand the cooperative reduction programs aggressively to other countries that require technical or financial assistance. The nuclear threat exists wherever nuclear materials exist. These materials cannot be eliminated, but they can be secured and safeguarded. We should more strongly support the International Atomic Energy Agency and provide more support to countries that try to implement UNSCR 1540 to prevent nuclear terrorism, for example.

We should enlist other nations such as China, India, and for that matter, Russia, to build a strong global partnership to prevent proliferation and combat nuclear terrorism. China and India have for the most part sat on the sidelines while the U.S. has led the fight. Russia has not engaged commensurate with its nuclear status. These efforts are particularly important if nuclear energy is to experience a real renaissance.

3) The hallmark of all of these efforts must be technology, partnership and in-country presence. The DOE/NNSA has in its laboratories the principal nuclear expertise in this country. It should be applauded for sending its technical experts around the world, often in very difficult situations (I met up with the DOE team in North Korea on a bitterly cold February day). However, both for structural reasons and budgetary shortfalls, that technical talent is slowing fading away. We do not have in place the necessary personnel recruitment or the working environment in the laboratories or the pipeline of students in our universities to replenish that talent. I strongly support the NNSA's Next Generation Safeguards Initiative, which is aimed at tackling this problem.

Mr. Chairman, when I first visited Russia's secret cities in 1992 shortly after the fall of the Soviet Union, I feared that its collapse may trigger a nuclear catastrophe. The fact that nothing really terrible has happened in the intervening 16 years is in great part due to the DOE/NNSA programs that your are considering today. We must now be just as innovative and creative to deal with the changing nuclear threat today.

In my statement I also mention the implications of my recent trips to North Korea and to India. However, since I am out of time, I will need to leave those for your questions.

Thank you for your attention.

A Wall Street Journal op-ed by former Secretaries of State George Shultz and Henry Kissinger, former Defense Secretary William Perry, former Senator Sam Nunn and other leading security experts advancing the vision of a world free of nuclear weapons and the concrete steps needed to make progress in that direction.

The accelerating spread of nuclear weapons, nuclear know-how and nuclear material has brought us to a nuclear tipping point. We face a very real possibility that the deadliest weapons ever invented could fall into dangerous hands.

The steps we are taking now to address these threats are not adequate to the danger. With nuclear weapons more widely available, deterrence is decreasingly effective and increasingly hazardous.

One year ago, in an essay in this paper, we called for a global effort to reduce reliance on nuclear weapons, to prevent their spread into potentially dangerous hands, and ultimately to end them as a threat to the world. The interest, momentum and growing political space that has been created to address these issues over the past year has been extraordinary, with strong positive responses from people all over the world.

Mikhail Gorbachev wrote in January 2007 that, as someone who signed the first treaties on real reductions in nuclear weapons, he thought it his duty to support our call for urgent action: "It is becoming clearer that nuclear weapons are no longer a means of achieving security; in fact, with every passing year they make our security more precarious."

In June, the United Kingdom's foreign secretary, Margaret Beckett, signaled her government's support, stating: "What we need is both a vision -- a scenario for a world free of nuclear weapons -- and action -- progressive steps to reduce warhead numbers and to limit the role of nuclear weapons in security policy. These two strands are separate but they are mutually reinforcing. Both are necessary, but at the moment too weak."

We have also been encouraged by additional indications of general support for this project from other former U.S. officials with extensive experience as secretaries of state and defense and national security advisors. These include: Madeleine Albright, Richard V. Allen, James A. Baker III, Samuel R. Berger, Zbigniew Brzezinski, Frank Carlucci, Warren Christopher, William Cohen, Lawrence Eagleburger, Melvin Laird, Anthony Lake, Robert McFarlane, Robert McNamara and Colin Powell.

Inspired by this reaction, in October 2007, we convened veterans of the past six administrations, along with a number of other experts on nuclear issues, for a conference at Stanford University's Hoover Institution. There was general agreement about the importance of the vision of a world free of nuclear weapons as a guide to our thinking about nuclear policies, and about the importance of a series of steps that will pull us back from the nuclear precipice.

The U.S. and Russia, which possess close to 95% of the world's nuclear warheads, have a special responsibility, obligation and experience to demonstrate leadership, but other nations must join.

Some steps are already in progress, such as the ongoing reductions in the number of nuclear warheads deployed on long-range, or strategic, bombers and missiles. Other near-term steps that the U.S. and Russia could take, beginning in 2008, can in and of themselves dramatically reduce nuclear dangers. They include:

  • Extend key provisions of the Strategic Arms Reduction Treaty of 1991. Much has been learned about the vital task of verification from the application of these provisions. The treaty is scheduled to expire on Dec. 5, 2009. The key provisions of this treaty, including their essential monitoring and verification requirements, should be extended, and the further reductions agreed upon in the 2002 Moscow Treaty on Strategic Offensive Reductions should be completed as soon as possible.
  • Take steps to increase the warning and decision times for the launch of all nuclear-armed ballistic missiles, thereby reducing risks of accidental or unauthorized attacks. Reliance on launch procedures that deny command authorities sufficient time to make careful and prudent decisions is unnecessary and dangerous in today's environment. Furthermore, developments in cyber-warfare pose new threats that could have disastrous consequences if the command-and-control systems of any nuclear-weapons state were compromised by mischievous or hostile hackers. Further steps could be implemented in time, as trust grows in the U.S.-Russian relationship, by introducing mutually agreed and verified physical barriers in the command-and-control sequence.
  • Discard any existing operational plans for massive attacks that still remain from the Cold War days. Interpreting deterrence as requiring mutual assured destruction (MAD) is an obsolete policy in today's world, with the U.S. and Russia formally having declared that they are allied against terrorism and no longer perceive each other as enemies.
  • Undertake negotiations toward developing cooperative multilateral ballistic-missile defense and early warning systems, as proposed by Presidents Bush and Putin at their 2002 Moscow summit meeting. This should include agreement on plans for countering missile threats to Europe, Russia and the U.S. from the Middle East, along with completion of work to establish the Joint Data Exchange Center in Moscow. Reducing tensions over missile defense will enhance the possibility of progress on the broader range of nuclear issues so essential to our security. Failure to do so will make broader nuclear cooperation much more difficult.
  • Dramatically accelerate work to provide the highest possible standards of security for nuclear weapons, as well as for nuclear materials everywhere in the world, to prevent terrorists from acquiring a nuclear bomb. There are nuclear weapons materials in more than 40 countries around the world, and there are recent reports of alleged attempts to smuggle nuclear material in Eastern Europe and the Caucasus. The U.S., Russia and other nations that have worked with the Nunn-Lugar programs, in cooperation with the International Atomic Energy Agency (IAEA), should play a key role in helping to implement United Nations Security Council Resolution 1540 relating to improving nuclear security -- by offering teams to assist jointly any nation in meeting its obligations under this resolution to provide for appropriate, effective security of these materials.

As Gov. Arnold Schwarzenegger put it in his address at our October conference, "Mistakes are made in every other human endeavor. Why should nuclear weapons be exempt?" To underline the governor's point, on Aug. 29-30, 2007, six cruise missiles armed with nuclear warheads were loaded on a U.S. Air Force plane, flown across the country and unloaded. For 36 hours, no one knew where the warheads were, or even that they were missing.

  • Start a dialogue, including within NATO and with Russia, on consolidating the nuclear weapons designed for forward deployment to enhance their security, and as a first step toward careful accounting for them and their eventual elimination. These smaller and more portable nuclear weapons are, given their characteristics, inviting acquisition targets for terrorist groups.
  • Strengthen the means of monitoring compliance with the nuclear Non-Proliferation Treaty (NPT) as a counter to the global spread of advanced technologies. More progress in this direction is urgent, and could be achieved through requiring the application of monitoring provisions (Additional Protocols) designed by the IAEA to all signatories of the NPT.
  • Adopt a process for bringing the Comprehensive Test Ban Treaty (CTBT) into effect, which would strengthen the NPT and aid international monitoring of nuclear activities. This calls for a bipartisan review, first, to examine improvements over the past decade of the international monitoring system to identify and locate explosive underground nuclear tests in violation of the CTBT; and, second, to assess the technical progress made over the past decade in maintaining high confidence in the reliability, safety and effectiveness of the nation's nuclear arsenal under a test ban. The Comprehensive Test Ban Treaty Organization is putting in place new monitoring stations to detect nuclear tests -- an effort the U.S should urgently support even prior to ratification.

In parallel with these steps by the U.S. and Russia, the dialogue must broaden on an international scale, including non-nuclear as well as nuclear nations.

Key subjects include turning the goal of a world without nuclear weapons into a practical enterprise among nations, by applying the necessary political will to build an international consensus on priorities. The government of Norway will sponsor a conference in February that will contribute to this process.

Another subject: Developing an international system to manage the risks of the nuclear fuel cycle. With the growing global interest in developing nuclear energy and the potential proliferation of nuclear enrichment capabilities, an international program should be created by advanced nuclear countries and a strengthened IAEA. The purpose should be to provide for reliable supplies of nuclear fuel, reserves of enriched uranium, infrastructure assistance, financing, and spent fuel management -- to ensure that the means to make nuclear weapons materials isn't spread around the globe.

There should also be an agreement to undertake further substantial reductions in U.S. and Russian nuclear forces beyond those recorded in the U.S.-Russia Strategic Offensive Reductions Treaty. As the reductions proceed, other nuclear nations would become involved.

President Reagan's maxim of "trust but verify" should be reaffirmed. Completing a verifiable treaty to prevent nations from producing nuclear materials for weapons would contribute to a more rigorous system of accounting and security for nuclear materials.

We should also build an international consensus on ways to deter or, when required, to respond to, secret attempts by countries to break out of agreements.

Progress must be facilitated by a clear statement of our ultimate goal. Indeed, this is the only way to build the kind of international trust and broad cooperation that will be required to effectively address today's threats. Without the vision of moving toward zero, we will not find the essential cooperation required to stop our downward spiral.

In some respects, the goal of a world free of nuclear weapons is like the top of a very tall mountain. From the vantage point of our troubled world today, we can't even see the top of the mountain, and it is tempting and easy to say we can't get there from here. But the risks from continuing to go down the mountain or standing pat are too real to ignore. We must chart a course to higher ground where the mountaintop becomes more visible.


Mr. Shultz was secretary of state from 1982 to 1989. Mr. Perry was secretary of defense from 1994 to 1997. Mr. Kissinger was secretary of state from 1973 to 1977. Mr. Nunn is former chairman of the Senate Armed Services Committee.

The following participants in the Hoover-NTI conference also endorse the view in this statement: General John Abizaid, Graham Allison, Brooke Anderson, Martin Anderson, Steve Andreasen, Mike Armacost, Bruce Blair, Matt Bunn, Ashton Carter, Sidney Drell, General Vladimir Dvorkin, Bob Einhorn, Mark Fitzpatrick, James Goodby, Rose Gottemoeller, Tom Graham, David Hamburg, Siegfried Hecker, Tom Henriksen, David Holloway, Raymond Jeanloz, Ray Juzaitis, Max Kampelman, Jack Matlock, Michael McFaul, John McLaughlin, Don Oberdorfer, Pavel Podvig, William Potter, Richard Rhodes, Joan Rohlfing, Harry Rowen, Scott Sagan, Roald Sagdeev, Abe Sofaer, Richard Solomon, and Philip Zelikow.

This summer the DOE Energy Information Agency released its study of the McCain/Lieberman Climate Stewardship bill, concluding that the largest single effect of these carbon controls would be the construction of 145 gigawatts of new U.S. nuclear capacity by 2030, more than doubling the existing 100 gigawatts. From the perspective of the early 1990's, today's resurgent interest in nuclear energy may appear surprising. This seminar will review what changed over the last 20 years that returned nuclear energy to broad public attention today, and will discuss the range of possible nuclear energy futures and their implications for security and the environment.

Per F. Peterson is Professor and previous chair of the Department of Nuclear Engineering at the University of California, Berkeley. He received his BS in Mechanical Engineering at the University of Nevada, Reno, in 1982.

Perry Award for her thesis, "Explaining the Use of Child Soldiers." The Firestone Medal recognizes the top 10 percent of undergraduate theses at Stanford each year, and the Perry recognizes excellence in policy-relevant research in international security studies.

CISAC honors students "can make the world a more peaceful place in several ways," FSI senior fellow Stephen Stedman told students and guests at the honors ceremony. "They can graduate and find jobs of power and influence [and] they can identify real world problems and solve them."

This year's class, which included several double-majors, represented nine major fields of study: biology, history, human biology, international relations, mathematics, management science and engineering, physics, political science, Russia-Eurasian studies. Some students headed to business or policy positions, while others looked forward to advanced studies in law, medicine, biophysics, security studies, or other fields.

"I hope that this is the beginning, not the end, of your contributions to policy-relevant research," CISAC senior research scholar Paul Stockton, who co-directed the program with Stedman, told the students. He added, "In every potential career you have expressed a desire to pursue, from medicine to the financial sector and beyond, we need your perspectives and research contributions, to deal with emerging threats to global security."

Many students expressed interest in realizing that hope. Burton said his aspiration is to attain "a high-level cabinet or National Security Council position to cap a long career of public service in foreign policy."

Katherine Schlosser, a biology major who is headed to Case Western Reserve University for joint MD-master's in public health program, said she hopes to "keep conducting innovative research and to eventually rejoin the international security studies community in some capacity."

The events of September 11, 2001 have heightened concerns about the potential for terrorist actions involving nuclear or radioactive materials and facilities. Questions about the vulnerability of such materials and facilities have forced governments to implement new security measures at the national level; however, such measures are of limited value in addressing influential factors in play beyond national boundaries. The existing nuclear weapons among states, is insufficient to address this new threat. A new, broader international nuclear security regime needs to be constructed. This regime must also take into account the growing influence of sub-state, trans-national actors. A key element in this new nuclear security regime is the important role international organizations can play in shoring up the weakness of the nation-state in a chaotic, post-Cold War international environment.

Ron Stansfield is current Coordinator of International Programmes at the Canadian Nuclear Safety Commission (CNSC) in Ottawa. Mr. Stansfield has over a quarter century of experience in international security issues, including non-proliferation, arms control and disarmament. Prior to joining the CNSC in 1991 as Senior Advisor on Non-proliferation, he served as Director Parliamentary Affairs at the Canadian Department of National Defence from 1988-1989. From 1975-1988, he held several positions at the Canadian Department of Foreign Affairs and International Trade (DFAIT), including Head of the Conventional and Nuclear Arms Control Section of DFAIT's Defence Relations Division (1986-1988) and diplomatic assignments in the Netherlands (1981-1985) and South Korea (1977-1979). From 1998-2001, Mr. Stansfield was seconded to the International Atomic Energy Agency in Vienna as a Senior Policy Office for nuclear non-proliferation and safeguards issues in the Agency's Office of External Relations and Policy Coordination. Mr. Stansfield is a graduate of the University of Saskatchewan and the Norman Paterson School of International Affairs at Carleton University.

Within the last 10 years several non-proliferation programs have been realized in Uzbekistan. Those programs include actions on upgrading physical protection systems of facilities possessing nuclear reactors and powerful radioactive sources, measures on improving nuclear security and radioactive safety, equipping the country's exit/entry points in order to prevent illicit trafficking of nuclear and radioactive materials, improving safeguards and radioactive monitoring of environment. Special attention was given to conversion of research reactors to low enrichment uranium and treatment of highly enriched fresh and spent reactor fuel. The programs have been performed in cooperation with U.S. energy and defense departments, the International Atomic Energy Agency and related institutions.

Bekhzod Yuldashev is a CISAC science fellow. He served as a consultant-advisor at the International Atomic Energy Agency in 2006-2007. Prior to that, he was director-general of the Institute of Nuclear Physics of the Uzbekistan Academy of Science from 1990 to 2006. From 1984 to 1990, he served as head of the laboratory in the Physical Technical Institute in Tashkent, where he had been a senior researcher since 1972.

Yuldashev has published about 300 scientific papers dedicated to various subjects of particle and nuclear physics in the wide range of primary energies. In particular, he experimentally obtained the first evidence of dibaryon resonances, discovered the effect of emitting energetic nucleons from local subsystems in nuclei, observed anomalously high production of eta-mesons and cumulative delta-isobars on nuclei and has experimentally proven that production and decay of vector and tensor resonances are the origins of so-called leading pions with an opposite sign to the primary one in high energy interactions. He has more than 20 patents on nuclear applications.

He is a full member of the Academy of Science of Uzbekistan and served as the academy's president from September 2000 through November 2005. In 2000-2004 he was elected a Member of Parliament of the Republic of Uzbekistan, and in 2004-2005 was elected a Senator.

He is a fellow of Islamic Academy of Sciences, a member of the American Physical Society. From 1992 to 2002, he was an elected member of the Scientific Council of the Joint Institute of Nuclear Research, in Dubna, Russia, one of two international nuclear centers in the world. He is also a member of the IAEA's Standing Advisory Group for Nuclear Applications, a fellow of the Islamic Countries Academy, and foreign member of the National Academy of Kazakhstan. He is an honorary professor of Samarkand State University and honorary doctor of the Joint Institute of Nuclear Research (2004). He won the 2004 Economic Cooperation Organization's excellence award in science and technology and the 1983 Uzbekistan State Prize for Science and Technology.

Yuldashev graduated from Tashkent and Moscow Universities in 1968. He earned his PhD in physics and mathematics from the Joint Institute of Nuclear Research, Dubna, Russia, in 1971.
