By the end of the year, scholars of security studies will be able to use a new website to learn how terrorist and militant organizations evolve over time and how they collaborate with--and compete against--one another.

"Mapping Terrorist Organizations," an interdisciplinary online project headed by CISAC Senior Fellow Martha Crenshaw, will focus initially on providing detailed, annotated information on militant and terrorist groups operating in Iraq since 2003, Pakistan and Afghanistan--areas of current policy concern for the United States. Future plans involve expanding research to include groups in Latin America, Europe, the Middle East and the United States and, if time and resources permit, to include major historical groups such as the Russian revolutionary movement.

The three-year project is funded by a $500,000 grant awarded to Crenshaw last fall by the National Science Foundation. It is part of the Department of Defense's Minerva Initiative launched in 2008 to support "research related to basic social and behavioral science of strategic importance to U.S. national security policy."

"No such study exists in the literature of terrorism," Crenshaw wrote in a report on the project. "Evolutionary mapping can enhance our understanding of how terrorist groups develop and interact with each other and with the government, how strategies of violence and non-violence are related, why groups appear and disappear, and how opportunities and constraints in the environment change organizational behavior over time." Furthermore, Crenshaw noted that visual mapping of highly complex, shifting information is likely to stimulate new observations that might otherwise have been overlooked."

Student involvement

Daniel Cassman, a 2010 CISAC honors graduate in political science and computer science, is building the site, which will contain interactive timelines, family trees and detailed group profiles. Cassman's programming--developed specifically for the website--will allow scholars to better understand and analyze patterns and structures of violent and non-violent opposition groups in multiple contexts.

At a June 1 meeting of a half dozen students working on the project, Crenshaw said one of the most challenging problems facing researchers is documenting how terrorist organizations evolve over time. With no official sources to rely on, Crenshaw's team spent the last year combing through government documents and academic research, autobiographies, newspaper reports and even jihadist websites-many of which disappear as quickly as they pop up. Crenshaw acknowledges that "precision in this field is elusive" even though the project emphasizes using documented primary sources. Students working on the project include Christy Abizaid and Sadika Hameed, 2010 graduates of the International Policy Studies master's program, and undergraduates Rob Conroy, Asfandyar Mir and Ari Weiss. CISAC staff member Julia McKinnon is assisting Crenshaw as well.

"We're keenly interested in changes in the sizes of groups," Crenshaw said. "That's one of the hardest things to figure out." It also is difficult to know when a group dissolves, becomes dormant or morphs into something else, she said. To obtain as complete a profile as possible, the website will include information about failed and foiled plots, as well as successful attacks, she said.

Charles Nicas, a student in International Policy Studies and Public Policy, said he joined Crenshaw's project to learn more about militancy and terrorism in South Asia. "The U.S. presence in Afghanistan and the fact that Pakistan is a nuclear-armed country mean that the U.S. will be involved in this region...for a long time," he wrote in an email. "The complexity of the situation takes a lot of research to understand."

Nicas's area of work focuses on sectarian groups in Pakistan, mainly Sipah-e-Sahaba Pakistan (SSP) and its offshoot Lashkar-e-Jhangvi (LeJ), both virulently anti-Shia groups. Nicas said SSP was founded in 1985 with state support and spawned LeJ in the mid-1990s. The groups are based in Punjab province in eastern Pakistan but had a significant presence in neighboring Afghanistan during Taliban rule. Both have become increasingly allied with militant groups in the border region, including al-Qa'ida, and are part of an umbrella group known as the Punjabi Taliban. "I've been surprised to learn how far back the roots of this problem go, which makes the challenge of effectively countering it especially daunting," Nicas said.

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.

Martin Hellman, a professor emeritus of electrical engineering who lectures on the risk analysis of nuclear deterrence, has organized a series of lectures aimed at increasing societal awareness of this threat, starting with Stanford's students and the campus community. Hellman argues that little will change until the public understands the risk everyone faces from nuclear weapons and can use this knowledge to demand change. All lectures, apart from the April 20 event, will take place from 7 to 8:30 p.m. in Room 201, Hewlett Teaching Center near Serra Mall. They are free and open to the public.

The Center for Strategic and International Studies (CSIS) hosted a live debate May 25 between Scott Sagan and Keith Payne, CEO and president of the National Institute for Public Policy. CSIS is a bipartisan, nonprofit organization in Washington, D.C.

Scott Sagan's Introductory Statement

I have been asked to address the question: "What should be U.S. declaratory strategic deterrence policy?"

I continue to believe, as I wrote in my 2009 Survival article, that,

"The United States should, after appropriate consultation with allies, move toward a No-First Use declaratory policy by stating that the role of U.S. nuclear weapons is to deter nuclear weapons use by other nuclear weapons states against the United States, our allies, and our armed forces and to be able to respond, with an appropriate range of nuclear retaliation options if necessary in the event that deterrence fails."

I believe that slow but steady movement toward a No-First Use (NFU) doctrine is in the U.S. interest because I think U.S. declaratory policy should have three characteristics.

U.S. declaratory policy should:

a) address the full range of nuclear threats to U.S. national security objectives (not just basic deterrence);

b) be accurate and consistent, reflecting actual military doctrine rather than being mere rhetoric; and

c) U.S. declaratory policy should reflect what U.S. leaders really might want do in the event of a deterrence failure.

In my brief opening remarks, I will explain these three points and outline the logic and evidence that leads me to the conclusion that the benefits of an NFU declaratory policy outweigh its costs.

Point #1: Deterrence is one, but only one critical U.S. national security objective and prudent decisions about declaratory policy regarding the use of nuclear weapons should take into account its likely effects on deterrence of adversaries, bit also the reassurance of allies, the further proliferation of nuclear weapons to additional states, the risks of nuclear terrorism, the impact of our declaratory policy on nuclear doctrines of other states; and the prospects for long-term nuclear disarmament. In this sense, the CSIS question (like previous Nuclear Posture Reviews (NPR) before this latest one) is too narrow in scope and could therefore lead to an excessively narrow, indeed a wrong-headed, answer. Historically, many actions and statements made in the name of deterrence - think of Richard Nixon's Madman Nuclear Alert over Vietnam or George W. Bush's suggestion that "All Options are on the Table" included nuclear preventive strikes on Iran -- might add just a smidgen of deterrence, but can be highly counterproductive with respect to other U.S. nuclear security goals. This is true of the NPR in general: just as war is too important to be left to the generals, nuclear declaratory policy is too important to be left solely to the Pentagon.

Opponents of this broader conception of nuclear posture claim that there is no evidence that U.S. nuclear posture influences others or perceptions that we are honoring our NPT Article VI commitments help with non-proliferation goals. That view is wrong. Let me give just two examples:

1. Evidence to support the point about U.S. disarmament steps helping encourage others to act is seen with Indonesia's decision to ratify CTBT earlier this month:

When Indonesia announced its decision it said it had taken note of the "serious effort" on the part of the current United States Administration in promote disarmament. "We do feel that at this time, what is needed is positive encouragement rather than pressure of a different type that we've been trying to impart in the past," he said, voicing hope that the U.S. will follow suit from his country's actions. "We are also cognizant of some positive aspects of the United States' Nuclear Posture Review."

2. For evidence on the doctrinal influence or mimicry point let me cite India. In January 2003, the BJP government in New Delhi, influenced by the U.S. NPR, adopted a revised, more offensive nuclear doctrine including the explicit threat of Indian nuclear first-use in response to biological or chemical weapons use. "India must consider withdrawing from this [NFU] commitment as the other nuclear weapons-states have not accepted this policy." Although it is too early to know the final result, the Indian government today appears to be reversing course: A group of very senior former officials has stated that, "It is time to review the objectionable parts" of India's nuclear posture and the Foreign Minister has called for universal declarations of NFU.

Point #2: U.S. Strategic Nuclear Declaratory Policy should be consistent with actual U.S. Nuclear Doctrine. That is, U.S. government officials should not misrepresent what its "real" nuclear policy is when it makes public statements about intent and plans. This may seem like an obvious point to some... but history suggests that this principle is not always followed--from Robert McNamara's mid-1960s declaratory statements about Assured Destruction (which often downplayed the heavy Counter-Force emphasis of U.S. doctrine at the time) to the Bush Administration's February 2002 statement in which in the same speech it "reaffirmed" the 1995 Negative Security Assurances not to use nuclear weapons against NNWS parties to the NPT unless they attack the U.S. or our allies with a NWS and, in the same speech, also stated that, "If a weapon of mass destruction is used against the United States or its allies, we will not rule out any specific type of military response. This followed the leaking of the classified portion of the 2001 NPR which reportedly placed Iran, Libya, and Syria on target lists, creating a flurry of negative international press reports.

In an era in which leaks should be considered highly likely, if not inevitable and, at a time in which we want more transparency around the world, the U.S. Government should err on the side of transparency. With multiple audiences present, calculated ambiguity may sometimes be necessary and even helpful; clear contradictions and calculated hypocrisy are not.

Here, I must give the current Administration some credit, for it judged that there was a small set of specific threats that could not currently be met by U.S. and allied conventional forces. It said so clearly in the Nuclear Posture Review and also clearly committed itself to deal with the challenge:

"The United States will continue to strengthen conventional capabilities and reduce the role of nuclear weapons in deterring non-nuclear attacks, with the objective of making deterrence of nuclear attack on the United States or our allies and partners the sole purpose of U.S. nuclear weapons." (p. ix)

Critics say that this will weaken extended deterrence as key allies will feel abandoned. Evidence so far is to the contrary:

  Japan: Foreign Minister Okada said, in October 2009, "We cannot deny the fact that we are moving in the direction of No-First Use of nuclear weapons. We would like to discuss the issue with Washington." The Japanese 2010 Rev Con statement said, "Japan appreciates and welcomes the Nuclear Posture Review by the United States." "We call on all states possessing nuclear weapons to reduce the role of nuclear weapons in their national security strategies. In this connection, we call on the Nuclear Weapon States to take, as soon as possible, such measures as providing stronger negative security assurances that they will not use nuclear weapons against Non-Nuclear-Weapon States that comply with the NPT." Japanese 2010 NPT Review Conference statement

  This is also the case in NATO: The German, Dutch, Belgian and Norwegian governments have all called for removal of the tactical nuclear weapons on their soil. NATO meetings will address this soon. We should not just assume that the credibility of extended deterrence and reassurance to allies is threatened by NFU declarations or removal of tactical weapons. Instead, we should listen to what our allies are saying and work with them.

Point #3: U.S. declaratory policy should reflect what the U.S. might really want to do if deterrence fails. Doctrine and declaratory policy should be made with an acute awareness that deterrence might fail and not succumb to the common wishful thinking biases that assumes perfect prospects of success. This leads me to appreciate the wise advice that Brent Scowcroft gave to President George H.W. Bush during the first Gulf War to avoid "spoken or unspoken threats to use them (Nuclear Weapons) on the grounds that it is bad practice to threaten something that you have no intention of carrying out."

When an official threatens actions that we have no intention of carrying out it can add a thin sliver of deterrence strength but at the grave cost, if the action occurs anyway, of either cheapening the currency of deterrence or risking the creation of a commitment trap that leads the state to execute an option that it otherwise would deem ill-advised. Here, I think of General Chilton's recent remarks about using nuclear threats to deter cyber attacks, as an example.

Here, I should note that in order to enhance non-proliferation and move slowly in the direction of a nuclear-free world the current NPR adds new NSAs and threatens conventional attacks only against NNWS in compliance with the NPT: "The United States will not use or threaten to use nuclear weapons against non-nuclear weapons states that are party to the NPT and in compliance with their nuclear non-proliferation obligations" (p.viii) and promises that its conventional responses would be "devastating" and that, "any individuals responsible for the attack, whether national leaders or military commanders , would be held fully accountable."

Dr. Payne, in his 2009 article, was critical of the whole goal of nuclear disarmament, despite the U.S. Article VI commitment to work in good faith toward that objective. He has written that, "The continuing threat posed by chemical and biological weapons is a fatal flaw in the logic of the nuclear-disarmament narrative, one that is all but ignored by its proponents.

"In fact, even if all enemies and potential enemies of the United States miraculously gave up their nuclear weapons, the United States would still need to maintain a nuclear deterrent arsenal. Why? Because some enemies reportedly retain other types of weapons of mass destruction (WMD), such as chemical and biological weapons, that could inflict enormous civilian casualties...If we also take nuclear deterrence off the table, we may, as Gen. Paul Fouilland, commander of the French Strategic Air Forces, has observed, 'Give a green light' to chemical and biological threats," Dr. Payne states.

I fail to see how a promise of "devastating" conventional responses and a promise that, "Any individuals responsible for the attack, would be held fully accountable" is giving any kind of green light to an adversary contemplating a chem/bio attack.

Furthermore, the only historical evidence that Dr. Payne cites to demonstrate his belief that, "Nuclear weapons threats have unique deterrent qualities" is the alleged success in deterring Iraqi use of Chem/Bio during the 1991 Gulf War:

The preponderance of evidence suggests that this is not right: Saddam did not use his WMD in 1991 because we threatened to march on Baghdad and overthrow his regime if he did that and "promised" to do that if he refrained from using his WMD.

First, look at the Bush, 25 January, 1991, letter to Saddam:

"Should war come it will be a far greater tragedy for you and your country. Let me state too that the United States will not tolerate the use of chemical or biological weapons or the destruction of Kuwait's oil fields and installations. Further, you will be held directly responsible for terrorist actions against any member of the coalition. The American people would demand the strongest possible response. You and your country will pay a terrible price if you order unconscionable acts of this sort." Two of the three things that Bush warned about happened...hardly good evidence that vague threats or calculated ambiguity worked as a deterrent.

Second, look at James Baker's memoirs in which he claimed that he "purposely left the impression that the use of chemical or biological agents by Iraq could invite tactical nuclear retaliation," but also warned Aziz that if Iraq used weapons of mass destruction, "Our objective won't just be the liberation of Kuwait, but the elimination of the current Iraqi regime." Advocates of maintaining calculated ambiguity too often cite the first statement but fail to cite the second Baker statement.

Third, look at what Saddam said under interrogation: "How would Iraq have been described if it had used nuclear weapons? A: "We would have been called stupid." In the May 2004 interrogation: "The WMD was for the defense of Iraq's sovereignty. Iraq demonstrated this with the use of WMD during the Iraq and Iran War, as Iran had threatened the sovereignty of Iraq. Yet, Iraq did not use WMD during the 1991 Gulf War as its sovereignty was not threatened."

In conclusion: I think you will discover today that reasonable people can certainly disagree about how to value and prioritize these different nuclear-related objectives and reasonable people can (and do) disagree about how best to pursue them. But reasonable people should not ignore the full range of U.S. objectives and narrowly conflate deterrence with security, should continue to search for evidence that supports or weakens their assumptions, and should engage in rigorous dialogues like this to help propel the debate forward.

The Obama administration's decision to preview its National Security Strategy at West Point highlighted its coverage of security crises from Afghanistan to North Korea. But back-to-back events at Brookings with Hillary Clinton and Samantha Power today showed that the core of the strategy is a deeper argument about the central challenge confronting America -- the increased impact on our economy and security of a new global reality.

For two decades, the United States could take economic and security supremacy for granted. Three things have changed.

First, the global economic boom. Yes, boom -- remember? Before the crash, there were two decades of uninterrupted growth in the global economy, global trade, and global financial activity. The U.S. profited, but so too did China, India and Brazil, which grew into major economic players; so did several others, like Mexico, Indonesia and Turkey, which have emerged as the new middle powers.

Second, the Iraq war. Love or loath U.S. policy in Iraq, it launched us into sustained expenditure of financial and military resources alongside another draining war in Afghanistan. In the minds of the Vulcans, decisive U.S. victory in Iraq was to assert global order by force of -- well, force. The strategy backfired, and rising states from Ankara to Brasilia found few, if any, costs to opposing U.S. strategy in the Middle East -- and domestic political points to be won. The Obama administration is feeling the consequences in its Iran policy.

Third, the global financial crisis. The bust, when it came, reaffirmed the centrality of the U.S. in the short term. But it also showcased the growing weight of the emerging economies, which now lead the global recovery. Before Lehman Brothers collapsed, other big players may have disliked our Middle East policy, but they banked -- figuratively and literally -- on our stewardship of the global financial system. Since then, doubts have crept in, and a new assertiveness to match.

The net result is rising global influence and solidifying regional power for China, India, and Brazil -- and less room for maneuver for the US.

The administration will be criticized in predictable terms from predictable quarters for acknowledging any of this, even in tacit terms: for 'giving ground' to the emerging powers, for 'ceding' American supremacy, for forgetting to carry a big stick while talking softly. But that dog won't hunt. The Bush administration had begun to adapt to these changed realities towards the end of its tenure, and the Obama administration deserves credit for putting the new global realities front and center in its assessment of U.S. national strategy. The core concepts of revitalizing international order, pressing others to take up their responsibilities and working within, not against, multilateral arrangements are the right ones.

The tougher question is, will it work? Skeptics will point to Chinese heel-dragging and Brazilian gallivanting on Iran to say no. Optimists will point to Chinese cooperation on the financial crisis, and everybody's cooperation on Somali piracy and counter-terrorism, to say yes.

The reality is, we don't know. There's a struggle in Beijing between betting on cooperation with the US, and those who seek sharper competition. A pro-U.S. strategy in India has the high ground for now, but divisions remain. The better angels in Brazil's foreign ministry can't quite hold back Lula's dalliance with global populism -- an October election there may tilt the balance.

But we know this much: if the U.S. doesn't try, no one will succeed. None of the emerging powers can underwrite stability, and none that are serious want the job. The emerging powers may not play ball, and if so, we'll be in a lose-lose global game. But only U.S. strategy can pull us into win-win, and the Administration is right to try. Making this point to the American people won't be popular; but reality is reality, and denial does not a strategy make.

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.

The release last week of the Obama administration's Nuclear Posture Review brings long overdue attention to the vital issue of U.S. strategic posture. Issues raised in the NPR and START have reinvigorated a crucial national nuclear dialogue that has been missing.

As the chairman and vice chairman of Congress's bipartisan Strategic Posture Commission, which issued its report last May, we have watched with great interest the administration's steady progress this past year on its Nuclear Posture Review and the START negotiations.

Themes from our report run through the Nuclear Posture Review and are embodied in the new START agreement. While debate and disagreement must be part of the crossfire in this renewed nuclear dialogue, we want to emphasize important dimensions of both the Posture Review and START treaty that figure prominently in our bipartisan report.

Now that the NPR is completed, we see that it is compatible with our recommendations. The review gives a comprehensive and pragmatic plan for reducing nuclear risks to the United States. We believe it offers a bipartisan path forward - while allowing for healthy disagreements on specific issues.

And it incorporates many of our points - such as pursuing a quick and modest reduction of nuclear weapons with Russia and sustaining the nuclear triad of land-based ICBMs, sea-based SLBMs and bombers. It also recognizes that nuclear weapons safeguarded U.S. security during the Cold War by deterring attack and that we will need them for deterrence in the foreseeable future, as long as others also possess them.

We also see that the NPR puts special emphasis, as our report recommended, on improving the nation's complex nuclear infrastructure and enhancing programs to recruit and keep the nation's best scientific minds. The administration's commitment to increase investment in our national laboratories also ensures that they continue their important role in sustaining a safe, secure and effective nuclear arsenal and in solving many other problems facing the nation.

The review is correct to make preventing nuclear terrorism and proliferation the top priority, while also seeking to strengthen deterrence and to reassure U.S. allies and recognizing the importance of strategic stability with Russia and an emerging China. Our commission reached the same conclusions.

The NPR's changes in U.S. declaratory policy - especially the assurance that Washington "will not use or threaten to use nuclear weapons against non-nuclear parties to the Nonproliferation Treaty that are in compliance with their nuclear nonproliferation obligations" - go beyond our recommendation that the U.S. retain "calculated ambiguity."

It is, however, a sensible variation on a theme that the U.S. should support nonproliferation while preserving deterrence for itself and its allies.

We also note that the NPR chose, as we advised, to avoid adopting a "no first use" policy for nuclear weapons while narrowing the scope of possible first use to "extreme circumstances" - language that was in our bipartisan report.

We believe that the substantial edge the U.S. has developed in conventional military capabilities, which the NPR notes, permits this country to sharply reduce reliance on nuclear weapons. But we caution those who make light of this major U.S. strategic advantage and its implications.

We support the NPR's call for the U.S. not to develop new nuclear weapons now. Our report similarly called for a case-by-case approach to extending the life of today's warheads. And we agree that the focus should be on safety, security and reliability - not developing new military capabilities.

The NPR echoes our call to negotiate a worldwide end to the production of new fissile materials - the key ingredients of nuclear weapons.

Our final report strongly endorsed the U.S. deterrence policy to cover our allies and partners with the U.S. nuclear umbrella - an objective the NPR also embraces.

The report suggested deploying proven missile defenses against threats such as North Korea and Iran but emphasized, as the NPR does, that these defenses should not be so big as to encourage Russia to add warheads to counter them, which would only undermine efforts to reduce nuclear weapons. We included China as well as Russia in this.

But in two areas, we believe the NPR might have fallen short of the mark.

First, we understand that the review considered declassifying additional information about the size and composition of the U.S. nuclear stockpile. It should have done so. This would demonstrate U.S. leadership on the transparency that is needed to secure nuclear materials globally and to bolster strategic stability with Russia and China.

Second, the NPR called for the consideration of conventional "prompt global strike" capabilities. But it did not explain whether these systems would have a niche role against small regional powers such as North Korea or be an ultimate substitute for nuclear weapons in deterrence with Russia and China.

We feel the former is the only sensible approach. Keeping this issue ill-defined creates needless anxiety in Moscow and Beijing that could lead to future problems.

Even with these two caveats, the 2010 Nuclear Posture Review makes important strides in charting a sustainable bipartisan path forward for the United States.

Healthy disagreement over some NPR specifics should not obscure the valuable contribution it makes to advancing U.S. security interests - resting, as it does in part, on our bipartisan 2009 Strategic Posture Commission report.

William J. Perry served as secretary of defense in the Clinton administration. He was chairman of the Congressional Commission on the Strategic Posture of the United States. James R. Schlesinger was the nation's first energy secretary and served as secretary of defense from July 1973 to November 1975. He was vice chairman of the Congressional Commission on the Strategic Posture of the United States.
