In 1920, the Irish Republican Army reportedly considered a terrifying new weapon: typhoid-contaminated milk. Reading from an IRA memo he claimed had been captured in a recent raid, Sir Hamar Greenwood described to Parliament the ease with which "fresh and virulent cultures" could be obtained and introduced into milk served to British soldiers. Although the plot would only target the military, the memo expressed concern that the disease might spread to the general population.

Although the IRA never used this weapon, the incident illustrates that poisoning a nation's milk supply with biological agents hardly ranks as a new concept. Yet just two weeks ago, the National Academy of Sciences' journal suspended publication of an article analyzing the vulnerability of the U.S. milk supply to botulinum toxin, because the Department of Health and Human Services warned that information in the article provided a "road map for terrorists."

That approach may sound reasonable, but the effort to suppress scientific information reflects a dangerously outdated attitude. Today, information relating to microbiology is widely and instantly available, from the Internet to high school textbooks to doctoral theses. Our best defense against those who would use it as a weapon is to ensure that our own scientists have better information. That means encouraging publication.

The article in question, written by Stanford University professor Lawrence Wein and graduate student Yifan Liu, describes a theoretical terrorist who obtains a few grams of botulinum toxin on the black market and pours it into an unlocked milk tank. Transferred to giant dairy silos, the toxin contaminates a much larger supply. Because even a millionth of a gram may be enough to kill an adult, hundreds of thousands of people die. (Wein summarized the article in an op-ed he wrote for the New York Times.) The scenario is frightening, and it is meant to be -- the authors want the dairy industry and its federal regulators to take defensive action.

The national academy's suspension of the article reflects an increasing concern that publication of sensitive data can provide terrorists with a how-to manual, but it also brings to the fore an increasing anxiety in the scientific community that curbing the dissemination of research may impair our ability to counter biological threats. This dilemma reached national prominence in fall 2001, when 9/11 and the anthrax mailings drew attention to another controversial article. This one came from a team of Australian scientists.

Approximately every four years, Australia suffers a mouse infestation. In 1998, scientists in Canberra began examining the feasibility of using a highly contagious disease, mousepox, to alter the rodents' ability to reproduce. Their experiments yielded surprising results. Researchers working with mice naturally resistant to the disease found that combining a gene from the rodent's immune system (interleukin-4) with the pox virus and inserting the pathogen into the animals killed them -- all of them. Plus 60 percent of the mice not naturally resistant who had been vaccinated against mousepox.

In February 2001 the American SocietyforMicrobiologists' (ASM) Journal of Virology reported the findings. Alarm ensued. The mousepox virus is closely related to smallpox -- one of the most dangerous pathogens known to humans. And the rudimentary nature of the experiment demonstrated how even basic, inexpensive microbiology can yield devastating results.

When the anthrax attacks burst into the news seven months later, the mousepox case became a lightning rod for deep-seated fears about biological weapons. The Economist reported rumors about the White House pressuring American microbiology journals to restrict publication of similar pieces. Samuel Kaplan, chair of the ASM publications board, convened a meeting of the editors in chief of the ASM's nine primary journals and two review journals. Hoping to head off government censorship, the organization -- while affirming its earlier decision -- ordered its peer reviewers to take national security and the society's code of ethics into account.

Not only publications came under pressure, but research itself. In spring 2002 the newly formed Department of Homeland Security developed an information-security policy to prevent certain foreign nationals from gaining access to a range of experimental data. New federal regulations required that particular universities and laboratories submit to unannounced inspections, register their supplies and obtain security clearances. Legislation required that all genetic engineering experiments be cleared by the government.

On the mousepox front, however, important developments were transpiring. Because the Australian research had entered the public domain, scientists around the world began working on the problem. In November 2003, St. Louis University announced an effective medical defense against a pathogen similar to -- but even more deadly than -- the one created in Australia. This result would undoubtedly not have been achieved, or at least not as quickly, without the attention drawn by the ASM article.

The dissemination of nuclear technology presents an obvious comparison. The 1946 Atomic Energy Act classifies nuclear information "from birth." Strong arguments can be made in favor of such restrictions: The science involved in the construction of the bomb was complex and its application primarily limited to weapons. A short-term monopoly was possible. Secrecy bought the United States time to establish an international nonproliferation regime. And little public good would have been achieved by making the information widely available.

Biological information and the issues surrounding it are different. It is not possible to establish even a limited monopoly over microbiology. The field is too fundamental to the improvement of global public health, and too central to the development of important industries such as pharmaceuticals and plastics, to be isolated. Moreover, the list of diseases that pose a threat ranges from high-end bugs, like smallpox, to common viruses, such as influenza. Where does one draw the line for national security?

Experience suggests that the government errs on the side of caution. In 1951, the Invention Secrecy Act gave the government the authority to suppress any design it deemed detrimental to national defense. Certain areas of research-- atomic energy and cryptography -- consistently fell within its purview. But the state also placed secrecy orders on aspects of cold fusion, space technology, radar missile systems, citizens band radio voice scramblers, optical engineering and vacuum technology. Such caution, in the microbiology realm, may yield devastating results. It is not in the national interest to stunt research into biological threats.

In fact, the more likely menace comes from naturally occurring diseases. In 1918 a natural outbreak of the flu infected one-fifth of the world's population and 25 percent of the United States'. Within two years it killed more than 650,000 Americans, resulting in a 10-year drop in average lifespan. Despite constant research into emerging strains, the American Lung Association estimates that the flu and related complications kill 36,000 Americans each year. Another 5,000 die annually from food-borne pathogens -- an extraordinarily large number of which have no known cure. The science involved in responding to these diseases is incremental, meaning that small steps taken by individual laboratories around the world need to be shared for larger progress to be made.

The idea that scientific freedom strengthens national security is not new. In the early 1980s, a joint Panel on Scientific Communication and National Security concluded security by secrecywasuntenable. Its report called instead for security by accomplishment -- ensuring strength through advancing research. Ironically, one of the three major institutions participating was the National Academy of Sciences -- the body that suspended publication of the milk article earlier this month.

The government has a vested interest in creating a public conversation about ways in which our society is vulnerable to attack. Citizens are entitled to know when their milk, their water, their bridges, their hospitals lack security precautions. If discussion of these issues is censored, the state and private industry come under less pressure to alter behavior; indeed, powerful private interests may actively lobby against having to install expensive protections. And failure to act may be deadly.

Terrorists will obtain knowledge. Our best option is to blunt their efforts to exploit it. That means developing, producing and stockpiling effective vaccines. It means funding research into biosensors -- devices that detect the presence of toxic substances in the environment -- and creating more effective reporting requirements for early identification of disease outbreaks. And it means strengthening our public health system.

For better or worse, the cat is out of the bag -- something brought home to me last weekend when I visited the Tech Museum of Innovation in San Jose. One hands-on exhibit allowed children to transfer genetic material from one species to another. I watched a 4-year-old girl take a red test tube whose contents included a gene that makes certain jellyfish glow green. Using a pipette, she transferred the material to a blue test tube containing bacteria. She cooled the solution, then heated it, allowing the gene to enter the bacteria. Following instructions on a touch-screen computer, she transferred the contents to a petri dish, wrote her name on the bottom, and placed the dish in an incubator. The next day, she could log on to a Web site to view her experiment, and see her bacteria glowing a genetically modified green.

In other words, the pre-kindergartener (with a great deal of help from the museum) had conducted an experiment that echoed the Australian mousepox study. Obviously, this is not something the child could do in her basement. But just as obviously, the state of public knowledge is long past anyone's ability to censor it.

Allowing potentially harmful information to enter the public domain flies in the face of our traditional way of thinking about national security threats. But we have entered a new world. Keeping scientists from sharing information damages our ability to respond to terrorism and to natural disease, which is more likely and just as devastating. Our best hope to head off both threats may well be to stay one step ahead.

On May 18 a roundtable organized jointly by CDDRL and CREEES and chaired by SIIS Senior Fellow Gail W. Lapidus brought together visiting scholars Temuri Yakobashvili from Georgia, Volodymyr Kulyk from Ukraine, Uladzimir Rouda from Belarus, and Wall Street Journal reporter Steve LeVine to examine the dramatic wave of democratic revolutions and protest movements which have transformed the geopolitics of the post-Soviet region over the past 2 years.

The participants argued that although the "Rose Revolution"in Georgia in October 2003, the Ukrainian "Orange Revolution" of November-December 2004, and the more recent regime change in Kyrgyzstan were all precipitated by popular protest against fraudulent elections, they expressed a deeper dissatisfaction with the widespread corruption and failures of the three governments, combined with the emergence of an increasingly mature and organized political opposition. While international organizations and actors played a supportive role in delegitimizing electoral fraud and nurturing civil society, domestic factors were the decisive ones in bringing about peaceful regime change.

The panelists also concurred that the "easy"revolts were now over. They predicted that future upheavals in the region were inevitable, but were far less likely to go smoothly. In Belarus, although popular hostility to a tyrannical political regime is growing, inspired by the successful example of neighboring Ukraine and the attraction of Europe, the absence of a united and organized opposition remains a major barrier. In Uzbekistan, the repressive regime of President Karimov has demonstrated its willingness to resort to violence to put down opposition, and to forestall international criticism by stigmatizing opponents as Islamist terrorists.

May 2005 opened with a bleak couple of weeks for the nuclear Non-Proliferation Treaty (NPT). Delegates from 189 countries struggled to settle on an agenda for the seventh 5-year review of the Treaty, North Korea announced a new extraction of plutonium from its reactor to make nuclear weapons, and Iran stood firm against European attempts to dissuade it from pursuing a nuclear energy program that could be diverted for weapons-making. Yet CISAC's George Bunn, in an interview with BBC's "The World," cautioned against despair.

As the first general counsel to the U.S. Arms Control and Disarmament Agency, Bunn has watched the NPT weather many diplomatic storms since it entered into force in 1970. Far from a failure, the treaty prevented nuclear weapons from becoming a commonplace in nations' defense programs, he said.

"I think that if there were no NPT, there would be something like 35 to 40 countries with nuclear weapons," Bunn explained. "When you think that at the time of our negotiations in the 60s, Sweden and Switzerland both had programs to explore the possibility of making nuclear weapons"--ambitions that the NPT helped dissuade--the treaty has provided incalculable benefits to world security. "If Sweden and Switzerland had nuclear weapons, think how many other countries would have them," he added.

Today the treaty's main weakness is its focus on states' possession of nuclear weapons, at a time when terrorists' ambitions to acquire the weapons is a major concern. At the treaty's outset, "terrorism wasn't perceived by us as a threat. The treaty hardly deals with the threat of terrorism," Bunn said.

Hans Blix, chairman of the International Commission on Weapons of Mass Destruction and former chief weapons inspector in Iraq, said at the Stanford Institute for International Studies' International Day, "Challenges in a New Era," on May 6 that he does not think the world faces a new nuclear arms race. Nuclear risks posed by terrorists and nations like Iran and North Korea could trigger a new nuclear arms race, warned CISAC Co-Director and Stanford professor Scott D. Sagan.

Blix said that there need not be a new arms race if the world diligently pursues diplomacy. Blix's speech attracted a strong response from Sagan, who participated in the same plenary panel titled "Looking Ahead: A New Nuclear Arms Race?" "I think there already is a new and very different kind of nuclear arms race going on," Sagan said. "It is a race between terrorists trying to develop a nuclear weapon and national and international efforts to stop that." As North Korea "race[s] ahead with its own persistent and provocative nuclear program," Sagan said the likelihood that the impoverished country will want to test its weapons or sell them to the highest bidder will increase. "I think Dr. Blix's paper greatly underestimates the threat of nuclear terrorism today," he said.

The exchange was one of many during the one day International Day that attracted hundreds of diplomats, policymakers, faculty and students. Other speakers included Oxford professor Paul Collier, the State Department counselor, Philip Zelikow, and Stonebridge International chairman, Samuel Berger. Zelikow and Berger both spoke on U.S. foreign policy.

The SIIS International Day also included discussion session on topics such as Russia's future, U.S. policy on the Korean peninsula, climate change, our energy future, United Nations reform, responses to infectious diseases, U.S.-European relations, and international criminal justice and security. Participants included both Stanford faculty and invited scholars, policymakers, and journalists.

Coit D. Blacker, director of SIIS, said the International Day, an annual event, will become part of the university's newly launched International Initiative that promotes interdisciplinary research and teaching. He also said the Stanford Institute for International Studies will be renamed the Freeman Spogli Institute for International Studies at Stanford University, effective September 1, in recognition of alumni Bradford Freeman, a member of the university's Board of Trustees, and Ronald Spogli, a member of the SIIS board of visitors, who together donated a lead gift of $50 million to help launch the initiative last month.

Fifty years ago, in April 1955 in Bandung, Indonesia, the country's then-president Sukarno hosted a meeting that became a global icon of anti-colonial solidarity. The 29 African and Asian states represented at that first Bandung Conference swore their support for sovereignty and self-determination. Their priority was on national not individual freedom. The final declaration mentioned human rights. But it ignored the danger that foreign colonialists might be replaced with indigenous dictators. Democracy, corruption, and good governance were issues for the future.

This year in Indonesia, from 18 to 24 April, some 87 delegations, including 40 heads of state or government and more than 100 ministers, celebrated the "golden jubilee" anniversary of the Bandung Conference. In a series of summit, ministerial, and other meetings they sought to "reinvigorate the Bandung spirit" and forge "a new Asian-African strategic partnership" for the 21st century. The week climaxed on 24 April on the same day and in the same hall where the original conferees had launched the "Bandung spirit" of solidarity against imperialism half a century before.

Some of the leaders gathered for the celebration -- Bandung II -- were content to repeat the nationalist pieties of the past, or to redirect them from European colonialism to American unilateralism as the enemy of the day. But the current president of Indonesia, Susilo Bambang Yudhoyono, known as SBY, struck a different note. His theme was not independence but introspection, not sovereignty but self-reform. He gently urged his fellow rulers to replace the old dogma of national liberation with a commitment to "good governance" as the latest and highest priority for developing countries -- in effect, self-reform as the new spirit of Bandung. At that moment, in Blitar, East Java, where he is buried, the nationalist firebrand Sukarno must have rolled in his grave.

"Good governance" did not and will not become the buzzword of Bandung II. The only other speaker who mentioned it, to my knowledge, was Singapore's prime minister Lee Hsien Loong. Fewer voices were raised in favor of self-reform than were aimed at American unilateralism. North Korea's Kim Yong Nam was among the latter. So was "Comrade R. G. Mugabe," as Zimbabwe's dictator called himself.

An Iraqi delegate, unable to insert in the ministers' communique a paragraph supporting his country's embattled transition to democracy, told me privately and bitterly, "The spirit of Bandung has not changed at all." In his view, most of the conferees in Bandung II preferred the odious sovereignty of Saddam Hussein to the induced democracy that followed, just as the leaders of the anti-colonial movement had tolerated tyrants in their ranks.

Yet SBY's speech did not fall on wholly deaf ears, and Iraq is not a good test case. More than a few delegates in Bandung supported democracy but opposed democracy-by-invasion. In developing countries, as representative government has spread, so has the desire to make it less corrupt and more effective. Over time, a new Asian-African agenda could give more prominence to democratization, religious moderation, the rule of law -- and honest, accountable governments as means to these ends.

But even if this does not happen, even if SBY's challenge is forgotten, the prestige of successfully hosting Bandung II already has strengthened his otherwise vulnerably "American" position inside a country whose future will help tip the balance of extremism and moderation in the Muslim world.

SBY is John F. Kennedy-esque: tall, handsome, young for a head of state, and able to project a democratic vision for Indonesia. A retired army general, he received American military and civilian training, including a master's in management from Webster University. No president before him has had more American exposure. This background will be in the spotlight when he pays his first presidential visit to the United States at the end of May.

Indonesia is the largest Muslim society, the third-largest democracy, and a tropical archipelago where defenders of the Bush administration are as scarce as snow. Indonesians will appreciate SBY's American experience if it enables him to deal with the world's only superpower in ways that help Indonesia. But if he is seen as too enamored of supposedly "American" values, he will create an opening for his political opponents.

In Bandung on the last day of the commemoration, crowds lined the streets, smiling and waving at the VIPs. Through the closed windows of air-conditioned limos and busses, the VIPs waved back. Compared with the week's grand abstractions -- sovereignty and self-reform -- this third spirit of Bandung was fleeting and local. But unless Asian-African solidarity becomes more than a slogan, or the vision of a better-governed Indonesia comes true, it may have been the most real.
