CISAC Co-Director Scott D. Sagan has been named The Caroline S.G. Munro Memorial Professor in Political Science. A member of Stanford's faculty since 1987, Sagan's research focuses on nuclear security and the emerging terrorist threat; nuclear proliferation, particularly in South Asia; ethics and international relations; and accidents in complex organizations. Before coming to Stanford, 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 served as a consultant to the Office of the Secretary of Defense 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 co-editor with Peter R. Lavoy and James L. Wirtz of Planning the Unthinkable (Cornell University Press, 2000) and the editor of Inside Nuclear South Asia (Stanford University Press, 2009). His most recent publications include "The Case for No First Use" in Survival (June 2009) and "Good Faith and Nuclear Disarmament Negotiations" in George Perkovich and James A. Acton's (eds.) Abolishing Nuclear Weapons: A Debate (Carnegie Endowment, 2009).

Sagan received Stanford's Hoagland Prize for Undergraduate Teaching in 1996, and the Dean's Award for Distinguished Teaching in 1998. As part of CISAC's mission of training the next generation of security specialists, he established Stanford's Interschool Honors Program in International Security Studies. He earned a bachelor's degree with high honors in government from Oberlin College and holds a doctorate in political science from Harvard University.

The Caroline S.G. Munro Memorial Professorship in Political Science

The Caroline S.G. Munro Chair was established by the Board of Trustees in 1981 in recognition of Mrs. Munro's farsighted commitment to strengthening scholarship and teaching at Stanford.

A series of gifts during her lifetime and a bequest endowing the William Bennett Munro Memorial Fund in 1973 in honor of her late husband--a professor of history and government at Harvard and the California Institute of Technology--were sufficient to support the William Bennett Munro Professorship in Political Science; the William Bennett Munro Memorial Lectures; and the Caroline S.G. Munro Memorial Professorship.

Caroline Sanford Gorton and William Bennett Munro were married in 1913. They had one child, William Bennett Munro, Jr., who graduated from Stanford in 1937. Their granddaughter, Jane Bruce Munro, was a member of the Class of 1968.

In accordance with Mrs. Munro's preferences, the professorship may be awarded in either political science or history.

The term laser weapon implies the use of a laser as part of a so-called directed energy weapon (DEW). In that case, the laser energy is causing the target damage. Military research led to the development of experimental lasers with continuous output powers up to 140 kW in 1966 and two Megawatts in 1980. However, those systems were huge and not part of laser weapon systems.

Since the 1980s the development in the military continued. Remarkably, civilian lasers, developed for industrial machining, have now reached output powers, which can be useful for DEW applications, too. Recently, several prototypes came into operation. On the one hand, there are industry-funded projects that use civilian of-the-shelf industrial lasers. On the other hand, there is government-funded research, which aims at high power laser systems. Major defense companies in the United States and elsewhere are working on both tracks.

Anti-satellite (ASAT) laser engagements would be a revolutionary laser application, as they would in principle enable an option of attacks on satellites with only minor debris. At the moment, attacking satellites implies the use of missiles with kinetic or explosive warheads. A kinetic impact creates debris, which would be harmful to the attacker's space assets, too. For that reason, space faring nations are discouraged from using kinetic energy attacks.

This fact enacts a kind of "natural" arms control. Lasers could change this situation, if they are used to heat up satellites just to a point where their electronics are damaged or only to impair their sensors. Hence, attacks on satellites would be more likely, if laser DEW with anti-satellite capabilities are fielded in peacetime. In a time of crisis, this would create additional political instabilities, as satellites are important early warning and reconnaissance assets.  A deployment of laser ASATs could eventually lead to an arms race in space. In order to make this scenario less likely arms control mechanism could be implemented.

This talk will focus on the technological background of laser ASATs. After a short introduction into recent technological developments, it will be examined whether current laser technology has the ability to endanger satellites. To achieve this, a physics-based method has been devised to assess laser DEW engagements. Damage mechanisms as well as possible distinctions between industrial laser setups and laser weapons will be examined in greater detail.  Options for controlling laser ASATs and obstacles for the implementations of such controls will be introduced.

Jan Stupl is a Postdoctoral Fellow at CISAC. His research concerns the current developments in laser technology regarding a possible application of lasers as an anti-satellite weapon (ASAT), as well as the proliferation of ballistic missiles. The research on laser ASATs focuses on damage mechanisms, the potential sources and countries of origin of laser ASATs and ways to curb their international proliferation. Regarding missiles, Jan is interested in the methods which are used to acquire ballistic missiles and possible ways to control this process.

Before coming to CISAC, Jan was a Research Fellow at the Institute of Peace Research and Security Policy (IFSH) at the University of Hamburg, Germany. His PhD dissertation was a physics-based analysis of future of High Energy Lasers and their application for missile defense and focused on the Airborne Laser missile defense system. This work was jointly supervised by the IFSH, the Institute of Laser and System Technologies at Hamburg University of Technology and the physics department of Hamburg University, where he earned his PhD in 2008.

Jan studied physics at the Friedrich-Schiller-University in Jena, Germany and at Warwick University in Coventry, UK. He concluded his undergraduate physics degree with a thesis in laser physics, receiving a German National Diploma in Physics in 2004. His interest in security policy and international politics was fuelled by an internship at the United Nations in New York in 2003.

Clay Moltz joined the National Security Affairs faculty of the Naval Postgraduate School (NPS) in June 2007. Since November 2008, he has held a joint appointment with the Space Systems Academic Group at NPS. He currently teaches Space and National Security, Nuclear Strategy and National Security, International Relations, and Northeast Asian Security. Prior to his appointment at NPS, he served for 14 years in various positions at the Monterey Institute’s Center for Nonproliferation Studies, including: deputy director from 2003-2007, director of the Newly Independent States Nonproliferation Program from 1998-2003, and founding editor of The Nonproliferation Review from 1993-98. He was also a faculty member in the Monterey Institute’s Graduate School of International Policy Studies.

Dr. Moltz received his Ph.D. and M.A. in Political Science from the University of California, Berkeley. He also holds an M.A. in Russian and East European Studies and a B.A. in International Relations (with Distinction) from Stanford University. Dr. Moltz worked previously as a staff member in the U.S. Senate and has served as a consultant to the NASA Ames Research Center, the Department of Energy’s National Nuclear Security Administration, and the Department of Defense’s Office of Net Assessment. He held prior academic positions at Duke University and at the University of California, San Diego.

It is widely acknowledged that Southeast Asia stands at a fork in the road. The ratification and adoption of the Association of Southeast Asian Nations (ASEAN) Charter in 2008 has given the regional body new found legal status, and the proposed establishment of an ASEAN Political-Security Community, Economic Community, Socio-Cultural Community and human rights body raises the potential for the rise of a strengthened form of regionalism in Southeast Asia, where ASEAN becomes not merely a forum for communication between Member States but an actor in its own right. However, working against this momentum has been a discernible stalling of democratisation and continuing commitment to traditional principles such as non-interference and consensus decision-making, which, in the eyes of some critics, produced a lowest common denominator approach to drafting the Charter. Both of these positions are canvassed and reviewed in this excellent collection, which offers sober and well-informed analysis of the predicaments that the region now confronts. Combining broad assessments of the relationship between security, democracy and regionalism with detailed analysis of the Charter and reform process, and telling insights into major controversies, such as the question of human rights in Myanmar, the problem of the haze in Indonesia, and the question of nuclear security, this is a model of balanced and sensible analysis.
 
The book is organised into four main sections, the first being a deeply insightful introduction by the editor. Too often, editorial introductions do little other than summarise the preceding chapters, but in this volume, Emmerson carefully places the key concepts in their proper context, neatly sets out the nature of the dilemmas currently confronting the region and provides insight into some of the most important contemporary crises – especially that relating to Myanmar. Subsequent sections focus on: ‘Assessments’ – of ASEAN and its reform process; ‘Issues’ – spanning democratisations, Myanmar, non-traditional security, the haze and nuclear security; Sukma’s discussion of democratisation and Caballero-Anthony’s account of non-traditional security stand out here; and ‘Arguments’ – namely, David Martin Jones’ calling for the privileging of prudence and decency over idealism and hasty democratisation, and Erik Martinez Kuhonta’s setting out the pros and cons of non-interference and intervention for human rights.
 
Overall, this book is very hard to fault. It combines a range of perspectives, including academic and policy perspectives, canvasses a number of relevant issues and provides the reader with a very good sense of the critical concerns. In short, those interested in understanding Southeast Asia’s contemporary fork in the road should start by reading this excellent volume.

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.

Paragraphs

In the aftermath of a terrorist attack political stakes are high: legislators fear being seen as lenient or indifferent and often grant the executive broader authorities without thorough debate. The judiciary's role, too, is restricted: constitutional structure and cultural norms narrow the courts' ability to check the executive at all but the margins. The dominant "Security or Freedom" framework for evaluating counterterrorist law thus fails to capture an important characteristic: increased executive power that shifts the balance between branches of government. This book re-calculates the cost of counterterrorist law to the United Kingdom and the United States, arguing that the damage caused is significantly greater than first appears. Donohue warns that the proliferation of biological and nuclear materials, together with willingness on the part of extremists to sacrifice themselves, may drive each country to take increasingly drastic measures with a resultant shift in the basic structure of both states.

“Laura Donohue’s sophisticated and complex analysis of counterterrorism law in Britain and the United States warns of the risks to fundamental individual rights when democracies establish counterterrorist regimes. Although governments frame their initiatives in terms of a choice between security and freedom, Donohue challenges this logic. Loss of liberty is not necessarily balanced by gain in safety. Compromises intended to be temporary turn out to be permanent. Leaders and citizens of democracies would be well advised to heed this pointed and timely warning.”

- Martha Crenshaw, Senior Fellow, Center for International Security and Cooperation (CISAC), Stanford University

An ambitious argument against the "Security or Freedom" framework, which is the dominant paradigm for thinking about counterterrorist law. The first book to compare the history of both British and American counterterrorist law. Argues that counterterrorist law is a danger to the rights central to liberal democracy: life, liberty, property, privacy and free speech.

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.

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.
