William J. Perry, former secretary of defense, and Siegfried S. Hecker, former director of Los Alamos National Laboratory, have joined forces to launch the Nuclear Risk Reduction initiative to address the changing nuclear threat following the end of the Cold War and the rise of international terrorism. The project is based at the Center for International Security and Cooperation (CISAC), which Hecker co-directs.

"I have worked with Sig for many years, both inside and outside government," Perry said. "I am particularly pleased to have such an able collaborator on this effort, which I have said is the work to which I will dedicate the rest of my career."

Hecker said he is excited to work with Perry to reduce the global nuclear threat. "Our primary objectives will be to work toward a world with fewer weapons, to have fewer fingers on the nuclear trigger and to keep nuclear weapons and materials out of the wrong hands," he said. "Time is of the essence both because of the urgency of the threat and because of the renewed hope that major powers are willing to take serious steps to realize these goals."

Hecker and Perry, both giants in the field of nuclear defense and security, plan to bring their considerable experience and associations with the U.S. and international policy, military and scientific communities to achieve these objectives.

The Nuclear Risk Reduction initiative (NRR) builds on the work of the Preventive Defense Project (PDP) that was established at Stanford and Harvard 13 years ago under the leadership of Perry and Ashton B. Carter, a former assistant secretary of defense in the Clinton administration. The two men, during their time in government, tackled some of the most important security issues following the breakup of the Soviet Union through promoting the concept of preventive defense, which seeks to diminish the possibility of potential threats escalating into actual threats and conflict. Carter is serving currently in the Obama administration as undersecretary of defense for acquisition, technology and logistics.

Hecker, as director of Los Alamos, was instrumental in creating the U.S. nuclear weapons stockpile stewardship program to meet the challenges of the post-Cold War environment without nuclear testing. He also helped reduce the nuclear threat posed by Russia and other republics in the chaotic years that followed the breakup of the Soviet Union. At Stanford, he has expanded his activities to include work in Northeast Asia, South Asia and the Middle East.

NRR's three-prong approach for making the world a safer place:

1. Working toward a world free of nuclear weapons

Perry, along with former secretaries of state George Shultz and Henry Kissinger, and former Sen. Sam Nunn, launched a joint effort in 2007 to refocus world attention on the critical need to eliminate nuclear weapons, starting with practical measures to make the world a safer place. President Obama, who has embraced this vision, has begun to adopt policies that will move the United States in this direction. The New Strategic Arms Reduction Treaty (New START), signed April 8, 2010, by Obama and Russian President Dmitry Medvedev, reduces the number of strategic arsenals in each country to 1,550 warheads. Now Perry and Hecker, through NRR, are conducting a risk/benefit analysis of ratification of the Comprehensive Test Ban Treaty (CTBT), another critical piece of legislation linked to nuclear weapon reductions. They will also explore with Russian colleagues deeper cuts in their respective nuclear arsenals along with engaging other nuclear weapons states on such critical issues.

2. Preventing proliferation of nuclear weapons

Perry and Hecker believe the risk of using nuclear weapons increases as more countries acquire them. Much of their focus is on the nuclear programs in North Korea and Iran, both of which threaten international peace and stability. In addition, as more states possess nuclear weapons and materials, it will become increasingly likely that fissile materials for an improvised nuclear device could fall into the hands of sub-national groups or terrorists.

Meanwhile, if there is to be a global renaissance of nuclear power, nations must learn how to manage potential proliferation risks associated with nuclear reactors and their fuel cycles. This is particularly critical if nuclear power spreads to developing countries that have expressed interest in this form of energy, since many have neither the requisite technological basis nor political stability to guarantee security.

3. Preventing nuclear terrorism

The 2010 Nuclear Security Summit in Washington, D.C. highlighted the importance of keeping nuclear weapons out of the hands of terrorists. As President Obama stated, "It is increasingly clear that the danger of nuclear terrorism is one of the greatest threats to global security-to our collective security." Despite this, some nations view the terrorist threat with less alarm. NRR plans to engage the technical and military leadership in key countries to promote a common understanding of the dangers posed by such threats and what steps are needed to mitigate them.

President Obama also warned, "Nuclear materials that could be sold or stolen and fashioned into a nuclear weapon exist in dozens of nations." Harvard's Graham Allison stated if countries could, "Lock down all nuclear weapons and bomb-usable material as securely as gold in Fort Knox, they [could] reduce the likelihood of a nuclear 9/11 to nearly zero." During the Nuclear Summit, Obama announced a goal to "lock down" all nuclear materials by 2014. This is a laudable objective, but Perry and Hecker know it will require much more than physical security to protect nuclear sites worldwide. The two men will work toward a cooperative, global effort to help countries develop modern, comprehensive nuclear safeguard systems that can provide proper control and accounting, along with physical protection.

Hecker has experience regarding such work. In 1994, he initiated a nuclear materials protection, control and accounting program (the lab-to-lab program) with Russia's nuclear complex. Perry and Hecker, through NRR, plan to reinvigorate and broaden the scientific cooperation that existed between the United States and Russia in the 1990s. Moreover, they plan to collaborate with the technical, military and policy communities in key countries to realize NRR's ambitious agenda of making the world a safer and more secure place.

Stanford seniors Sam Stone and Ashley Lohmann have been awarded the Firestone Medal and Perry Prize, respectively, for their theses on energy import dependence and the Jihadist terrorist threat to the United States since 9/11.

Stone and Lohmann discussed their findings during a CISAC seminar on June 2. Their papers are available below.

The Firestone Medal for Excellence in Undergraduate Research recognizes the top 10 percent of all honors theses in social science, science and engineering. The William J. Perry Prize is awarded to a student for excellence in policy-relevant research in international security studies. Both recipients are students in CISAC's Undergraduate Honors Program in International Security Studies, directed this year by Senior Fellow Stephen J. Stedman and Thomas Fingar, the Oksenberg/Rohlen Fellow.

Sam Stone, a student in the Department of Mathematics and Program in International Relations, wrote "Gas & Geopolitics: The Foreign Policy Implications of Energy Import Dependency."

Stone's thesis abstract states: "In recent years, much attention has focused on the dangers of dependency on energy imports. Fears of energy import dependency are particularly acute in Eastern Europe, where most countries remain heavily dependent on Russian gas, but similarly dependent relationships exist across the globe. Most energy security research focuses on exporters; this thesis contributes to the study of energy security by exploring the effects of energy dependence on importers."

During 2010-11 academic year, Stone, as a Fulbright Fellow, will study Russian foreign policy, in particular energy security issues and nuclear nonproliferation efforts at Moscow State University. He also plans to continue working with the Stanford US-Russia Forum, an initiative that brings together American and Russian students to explore global issues.

Ashley Lohmann, a student in the Program in International Relations, wrote, "Jihad on Main Street: Explaining the Threat of Jihadist Terrorism to the American Homeland since 9/11."

Lohmann's abstract states: "Since September 11, 2001, 26 jihadist plots and attacks have targeted the American homeland, but because the details of the plots and attacks as well as the profiles of their perpetrators vary greatly, scholars, government officials, and other authorities still disagree about the seriousness of threat posed by jihadist terrorism to the United States. This study provides a clearer understanding of the nature of jihadist terrorism in the U.S. by examining all 26 plots and attacks in detail. It concludes that jihadist terrorism is generally a minimally threatening, homegrown phenomenon, but some plots and attacks still emerge that do pose a serious threat to U.S. national security."

Stedman and Fingar described the award-winning theses as the very best in an exceptionally strong field of submissions by members of this year's honor's class.  "Sam Stone's creative and rigorous use of case studies and 'large N' data to to examine hypotheses about the effects of energy dependence gives decision makers theoretical and empirical tools to anticipate and ameliorate unwanted consequences of dependence on foreign sources of oil and gas," Fingar said. "Ashley Lohmann's rigorous examination of factors contributing to the success or failure of Jihadist threats to the American homeland provides valuable insights on the magnitude and character of such threats and how best to address them. These were the best, but other theses were also worthy of special recognition and we learned much from the work of every member of the class."

The American Academy of Arts and Sciences has published a paper with seven essays from leading scholars invited to respond to Scott Sagan's concluding essay Shared Responsibilities for Nuclear Disarmament in the Fall 2009 special issue of Daedalus on the global nuclear future. The paper includes Sagan's original essay and responses by James M. Acton, Jayantha Dhanapala, Mustafa Kibaroglu, Harald Muller, Yukio Satoh, Mohamed I. Shaker and Achilles Zaluar.

As Leslie Berlowitz, CEO of the American Academy of Arts and Sciences, states in an excerpt from the paper's introduction:

"Renewed interest in arms control and restated commitments to the longterm goal of nuclear disarmament have clearly increased over recent years, most dramatically with President Barack Obama's April 2009 speech in Prague. With that change in focus comes an opportunity for the international community to rethink how Article VI of the NPT is traditionally interpreted and to move beyond the cycle of repeated complaints from the 'have-nots' that the 'haves' are not doing enough to disarm themselves and repeated retorts by the "haves" that they are already taking every step that is realistic or prudent. The promise of a different approach to the commitments made under the NPT forms the basis of the Scott Sagan's valuable article--"Shared Responsibilities for Nuclear Disarmament"...

"The differences in national perspectives and the differences in individual opinions about appropriate disarmament steps among the authors should not mask a commitment they all share. The contributors to this volume agree that new thinking and continued debate about how best to maintain momentum toward nuclear disarmament is to be welcomed. Only by seeking out, and taking into consideration, a cross section of views can progress toward the goal of a nuclear-weapons-free world continue... 

"Their contributions serve to expand the discussion that was started by the original Daedalus article--and together they are intended to spark renewed policy debates about how best to pursue global disarmament, debates that will be prominent at the May 2010 NPT Review Conference in New York City and in the years following that important meeting."

Leaders or representatives from 47 countries recently attended the nuclear security summit in Washington. By holding a bilateral meeting with U.S. President Barack Obama and delivering an important speech at the summit, Hu Jintao highlighted China's positive image for people across the globe and helped reverse the deterioration of US-China relations.

Obviously, it takes a long path toward establishing a global mechanism to counter nuclear proliferation and nuclear terrorism. Many of these leaders were not quite sure whether they would come away from the summit empty-handed.

However, they decided to attend the summit mainly to respond positively to Obama, who had launched a number of initiatives to build a nuclear-free world. The same is true for Hu Jintao and his decision to attend the summit.

Hu's visit to Washington will help lead the bilateral relations toward a positive direction. Although some disputes continue between the two countries, Hu's visit to Washington will no doubt contribute to lowering U.S. hostility toward China.

Earlier, the rapid increase in GDP had stimulated some Chinese diplomats to take blind pride in dealing with their foreign counterparts. Now, it is time to rethink whether it is necessary to adhere to the well-established principle of keeping a low profile in handling Sino-American relations.

China's GDP will soon become the second largest in the world. Who is the greatest beneficiary from the pursuance of this principle over the past three decades? Needless to say, it is China.

Now, China is just halfway through its course of "peaceful rise." In the foreseeable future, the United States will remain the No. 1 power in the world. Two decades from now, who will become the greatest beneficiary if China, as the biggest developing country, is able to maintain stable relations with Washington? Obviously, the answer is China.

In his opening statement at the summit, Obama pointed out that in today's world, the world has reduced the risk of a nuclear war between big powers, but the threat of nuclear terrorist assaults is increasing. He is right. Terrorists can penetrate all places throughout the world without leaving a trace.

It is difficult for all major powers, especially the United States, to detect and prevent them from launching assaults including sudden attacks with "dirty bombs" as weapons. As such, the whole world faces the most serious security challenge.

Such a strategic assessment prompted Obama to convene the nuclear security summit as well as his earlier initiative of "a world free of nuclear weapons." Preoccupied by this assessment, he has spared no effort to promote the campaign of countering nuclear proliferation and nuclear terrorism.

To fight nuclear terrorism, the summit focused on establishing an international nuclear security mechanism. The United States and many countries face the threat of nuclear terrorism. China is no exception.

In case the East Turkistan separatists consider the timing is mature to intensify conflicts with Beijing, they will no doubt take whatever means necessary to penetrate nuclear facilities or acquire "dirty bombs." Moreover, the large-scale construction of nuclear power plants in China introduces more security challenges. China will be in the peak period of building such plants in the next two decades.

The ongoing construction of such plants scattered in coastal areas would expose the nation to threat. A terrorist attack on even one plant would result in consequences more serious than that of detonating a nuclear bomb over a city. Taking this into account, Beijing has adopted various measures to strengthen nuclear security in recent years.

As a positive response from China to the international community, Hu Jintao made the decision to attend the summit, which reflects that Beijing and Washington actually are sharing common interests by making joint efforts to establish a global mechanism for countering nuclear proliferation and nuclear terrorism.

This action indicates that Beijing regards nuclear terrorist assaults as a huge threat to national security interests and it hopes to strengthen international cooperation to limit or even eliminate this type of threat.

Also, this decision has indeed enabled China to avert a head-on collision with the United States and helped reverse a deterioration of U.S.-China relations. Based on this, we can suppose that Beijing is able to conduct strategic adjustment at a critical moment and formulate appropriate foreign policies.
