As a new era of democratic change swept across the Arab world this year, the Program on Arab Reform and Democracy (ARD) at the Center on Democracy, Development, and the Rule of Law hosted two conferences to examine the Arab Spring. On April 29, twelve internationally renowned Egypt scholars convened at Stanford to probe the root causes of the Egyptian revolution and debate the challenges facing the transition period. The second annual ARD conference held May 12-13, brought Arab activists and academics from the region together to provide a comparative perspective on political activism.

Participants in the Democratic Transition in Egypt conference were hesitant to label the popular uprising in Egypt a revolution in light of the fragile transition period. According to Professor Jason Brownlee of the University of Texas at Austin, "repressive agencies of the old order still exist in Egypt: the military intelligence, state security, and the general intelligence service."

Scholars unanimously agreed that nascent opposition parties face the enormous challenge of organizing during a hurried transition period and within a competitive party and campaign structure. Professor Samer Soliman from the American University in Cairo emphasized this point, "the party law is designed to bias the old guard and a legacy of suspicion towards political parties leaves youth hesitant to join or form political parties."

Significant discussion was dedicated to the role of the Muslim Brotherhood who many argued is the only well-organized opposition party in Egypt capable of commanding a majority in the upcoming parliamentary elections. Scholars were left wondering how to translate the success of this popular movement into a constitutionally-based political system representative of all societal interests.

The From Political Activism to Democratic Change in the Arab World conference featured eight activists from Tunisia, Egypt, Lebanon, Syria, Jordan, Morocco, Bahrain, and Yemen--in addition to a live presentation from Ramallah by Mustafa Barghouthi --who were joined by leading scholars to provide a grassroots perspective and original voice to the uprisings.

Panels presented country-based case studies highlighting the key challenges activists face in diverse Arab states and societies to evaluate the potential of democratic transition to take root. While variation exists in each country, it was clear that activists faced the same obstacles in pursuit of their goals and clearly benefitted from this shared forum at Stanford.

Participants emphasized the contagion that spread protests across the region, beginning in Tunisia. Stéphane Lacoix of Sciences Po illustrated this point, "a new generation of young political activists connected through social networks learned through the revolutionary experiences of their Facebook friends."

Looking forward, participants agreed that these revolutions are far from complete and challenging work lies ahead. According to CDDRL director Larry Diamond, "democratic change is not produced by grassroots protest and activism alone but requires organization, strategy, and hierarchical structure.”

In each Arab country, tribal, sectarian, political, and religious division threaten the stability of the fragile transition period. In the near term, participants stressed the importance of delaying elections to give time for political parties, institutions, and leadership to develop so the status quo does not reassert itself.

The role of external actors-- from the US to the GCC--was cited as exerting influence on the internal politics in each country. Activists collectively commented on the inconsistency of US foreign policy in the region, which has placed strategic interests above ideological ones, not actively pressing for change in Bahrain, Jordan, and Syria in the same way as in Tunisia, Egypt, and Libya.

A tone of cautious optimism imbued both conferences as scholars and activists alike were hesitant to declare the Arab Spring a success, stressing that time will determine the ultimate outcome. Both conferences allowed the ARD Program to make a substantial contribution to the body of scholarly research on this topic as conference papers will be published in an edited volume.

The decades-long political winter in the Arab world seemed to be thawing early this year as mass protests toppled Tunisian President Zine el-Abidine Ben Ali in January and Egyptian President Hosni Mubarak in February. It appeared as though one rotten Arab dictatorship after another might fall during the so-called Arab Spring. Analogies were quickly conjured to 1989, when another frozen political space, Eastern Europe, saw one dictatorship after another collapse. A similar wave of democratic transitions in the Arab world was finally possible to imagine, particularly given the extent to which previous transformations had been regional in scope: Portugal, Spain, and Greece all democratized in the mid-1970s; much of Latin America did shortly thereafter; Korea and Taiwan quickly followed the Philippines’ political opening in 1986; and then a wave of change in sub-Saharan Africa began in 1990. All of those were part of the transformative “third wave” of global democratization. In March, many scholars and activists reasonably imagined that a “fourth wave” had begun. 

Two months later, however, a late spring freeze has seemingly hit some areas of the region. And it could be a protracted one. Certainly, each previous regional wave of democratic change had to contend with authoritarian hard-liners, opposition divisions, and divergent national trends. But most of the Arab political openings are closing faster and more harshly than happened in other regions -- save for the former Soviet Union, where most new democratic regimes quickly drifted back toward autocracy.

If Tunisia still provides grounds for cautious optimism, the Egyptian situation is already deeply worrying. Its senior officer corps, which currently controls the government, does not want to facilitate a genuine democratic transition. It will try to prevent it by generating conditions on the ground that discredit democracy and make Egyptians (and U.S. policymakers) beg for a strong hand again. The ruling officers have turned a blind eye to mounting religious and sectarian strife (and an alarming explosion in crime). The military has spent enormous effort arresting thousands of peaceful protesters in Tahrir Square and trying them in military tribunals over the last two months. (In April, one such detainee, a blogger named Maikel Nabil, was sentenced to three years in prison for “insulting the military establishment.”) Yet it claims that it cannot rein in rising insecurity. Many Egyptians see this as part of the military’s grand design to undermine democracy before it takes hold.

The parliamentary elections slated for September are unlikely to help: New political forces have no chance of being able to build competitive party and campaign structures in time. The Muslim Brotherhood, which initially said it would only contest a third of the parliamentary seats, has now announced its intention to contest half of all seats, forming a new political party (Freedom and Justice) for the purpose. If the electoral system retains its highly majoritarian nature, it might well win a thumping majority of the seats it contests (perhaps 40 percent in all), with most of the rest going to local power brokers and former stalwarts of the Mubarak-era ruling party, the National Democratic Party.

Both theory and political experience teach that regimes with spent legitimacy do not last, and the legitimacy of the Libyan, Syrian, and Yemeni dictators is utterly depleted.

Elsewhere in the region, Bahrain’s minority Sunni monarchy opted to crush peaceful protests and arrest and torture many of those with whom it might have negotiated some future power-sharing deal. With active Iranian support and a bizarre degree of American and Israeli acceptance, Syrian President Bashar al-Assad unleashed a slow-motion massacre that could go on for weeks or even months. In Yemen, the government is paralyzed, food prices are rising, and the country is drifting. Having seen the fate of Mubarak, Yemeni President Ali Abdullah Saleh is playing for time, but his legitimacy is irretrievably drained, and he lacks the ability to mobilize repressive force on the scale of Assad’s.

Of course, not every country in the region has been affected by the apparent freeze and some could still avoid it. Jordan and Morocco are not yet in crisis but could be soon. Both countries face the same conditions that brought down seemingly secure autocracies in Tunisia and Egypt -- mounting frustration with corruption, joblessness, social injustice, and closed political systems. Not yet facing mass protests, Jordan’s King Abdullah is in a position to lead a measured process of democratic reform from above to revise electoral laws, rein in corruption, and grant considerably more freedom. Yet there is little sign that he has the vision or political self-confidence to modernize his country in this way.

Morocco’s King Mohammed VI is still domestically revered and internationally cited as a reformer, but he is even weaker and more feckless than Abdullah. He has been unwilling to rein in the deeply venal interests that surround the monarchy, or ease the country’s extraordinary concentration of wealth and business ownership. Instead, his security forces, narrow circle of royal friends, and oligopolistic business cronies fend off demands for accountability and reform, further isolate the king, and aggravate the political storm that is gathering beneath a comparatively calm surface.

For now, both monarchies are treading familiar water: launching committees to study political reform but never moving toward real political change. This game cannot last forever. As a former Jordanian official recently commented to me privately: “Everyone is expecting serious changes to the way the king rules the country, and if these changes don’t happen, the system will be in trouble. The king can’t keep talking about reform without implementing it.”

Scholars of the Arab world had been arguing for years that the region’s various repressive regimes (not least Saudi Arabia’s Al Saud dynasty, which keeps several thousand princes on the take) would either pursue democratic reform, or rot internally until they were overthrown. Ultimately, the options remain the same for the regimes that have avoided revolution this year. Those who have reasserted authoritarianism will find only temporary reprieve. Both theory and political experience teach that regimes with spent legitimacy do not last, and the legitimacy of the Libyan, Syrian, and Yemeni dictators is utterly depleted. They will surely be overthrown if not now, then in coming years. The Jordanian and Moroccan monarchies, however, could still survive if they spend what remains of their political legitimacy on democratic reform. In other words, even if the Arab spring comes in fits and starts, it will eventually bring fundamental political change. But whether democracy is the end result depends in part on how events unfold and how regimes and international actors engage the opposition forces.

Short of the wars that have periodically broken out in the region, the United States has never faced a more urgent set of opportunities and challenges there: real prospects for democratic development exist alongside the very real risks of Islamist ascension, political chaos, and humanitarian disaster. Countries across the Arab world differ widely in their political structures and social conditions, and the United States cannot pursue a one-size-fits-all strategy. But there are a few basic principles that it should apply everywhere. As it has generally and in a number of specific cases, the Obama administration must explicitly and consistently denounce all violent repression of peaceful protest. And it should enhance the credibility of those words by tying them to consequences. For example, in Libya, the United States identified and froze the overseas assets of top officials who were responsible for brutality. Additionally, it imposed travel bans on them and their family members, and asked Europe to do the same. In the past few days, the Obama administration has also moved to freeze the personal assets of Assad and other top Syrian officials. In extreme cases -- Libya is one, and Syria has now become another -- the United States can press the United Nations Security Council to refer individuals to the International Criminal Court for crimes against humanity.

When Arab governments turn arms against peaceful protesters, the United States and Europe should stop supplying them with weapons. Western countries have been selling (or giving) regimes, such as Saleh’s in Yemen, the tools of repression, including tear gas, ammunition, sniper rifles, close-assault weapons, and rockets and tanks. Although Saleh may have been a valuable asset in the fight against terrorism at one time, he has become a liability. By ending such trade, the United States would firmly send the message to the leaders of Bahrain (another recipient) and Yemen that if they are going to violently assault and arbitrarily arrest peaceful demonstrators for democracy, they are at least not going to continue doing so with U.S. guns.

For now, there is an urgent need for mediation to break the impasse between rulers and their oppositions and to find ways to ease the region’s remaining dictators out of power. Recognizing the need for an active UN role during the Arab uprising, UN Secretary-General Ban Ki-moon has begun to dispatch experienced and talented UN staff to engage in dialogue with different groups in Yemen and elsewhere. These diplomats can help develop possible political accommodations with the protesters. The United States should encourage the UN to try to mediate these conflicts, reconcile deeply divided forces within political oppositions, and help governments pave the way for credible elections. Because it is more neutral, the UN is the international actor best suited to mediate as well as convene experts on institutional design and help supply technical support for drafting constitutions.

American diplomats will have their own role to play: They can channel financial and programmatic support and provide another venue for different actors to meet and discuss differences. They should also speak out for human rights, civil society, and the democratic process. Such expressions of moral and practical support have made a significant difference in transitional situations in other countries, such as Chile, the Philippines, Poland, and South Africa. The Arab world has its own distinct sensitivities, but the ongoing uprisings present an unusual opportunity for U.S. ambassadors to join with representatives of other democracies to lean on Arab autocrats and aid Arab democrats.

The United States should help Arab democrats get the training and financial assistance they need to survive while urging them to cooperate with one another. This does not just mean more grants to civil society organizations. There is, of course, a need for such funding, but too much U.S. money thrown at these groups will discredit them as “American pawns” or promote corruption. Aid should be pooled among multiple donors, provide core (rather than project-related) funding for organizations with a proven track record of advancing democratic change, and must be carefully monitored to ensure that it is being used effectively.Western countries have been selling (or giving) regimes, such as Saleh’s in Yemen, the tools of repression, including tear gas, ammunition, sniper rifles, close-assault weapons, and rockets and tanks.

Finally, given its enormous demographic weight and political influence in the Arab world, as Egypt goes, so will go the region. Engaging Egypt will prove vital to any larger strategy of fostering democratic change in the Arab world. Beyond aid and vigilant monitoring of the political process, the United States must deliver a clear message to the Egyptian military that it will not support a deliberate sabotage of the democratic process, and that a reversion to authoritarianism would have serious consequences for the U.S.-Egyptian bilateral relationship, including for future flows of U.S. military aid. The United States cannot allow the Egyptian military to play the cynical double game that the Pakistani military has, or Egypt may become another Pakistan in two senses: an overbearing military may hide behind the façade of democracy to run the country, and the military may consort with our friends one day and our enemies -- radical Islamists within Egypt and Hamas outside it -- the next, to show it cannot be taken for granted.

This period of change in the Arab world will not be short or neatly circumscribed. Not a continuous thaw or freeze, the coming years will see cycles -- ups and downs in a protracted struggle to define the future political shape of the Arab world. The stakes for the United States are enormous. And the need for steady principles, clear understanding, and long-term strategic thinking has never been more pressing.

The Center for Democracy, Development and the Rule of Law (CDDRL) hosted a conference on the democratic transition in Egypt on Friday as part of its Program on Arab Reform and Democracy.

A series of four panels explored a number of issues surrounding the transition to democracy following the overthrow of President Hosni Mubarak. Prominent scholars from Stanford and other institutions participated in the conference.

Twelve Egypt scholars from American, Egyptian and European universities and think tanks convened in four panels throughout the day to discuss the revolution, the transition process, the changing political landscape and Egypt's future. The conference was co-sponsored by the Abbasi Program in Islamic Studies.

Panelists included Hoover Institution senior fellow Larry Diamond, history professor Joel Beinin, political science assistant professor Lisa Blaydes, CDDRL visiting scholar Ben Rowswell and CDDRL Program Manager Lina Khatib. They were joined by academics from Kent State University, Harvard University, Georgetown University, the University of Texas, Notre Dame University, the University of Exeter, the American University in Cairo and the Brookings Doha Center.

Each panel featured an introduction by the chair, followed by two or three 30-minute talks by panelists and a 30-minute Q&A session.

Emad Shahin, an associate professor of religion, conflict and peacebuilding at Notre Dame, opened the first panel with a talk that emphasized the role of the youth in charging the 18 days of protest that toppled former President Hosni Mubarak.

"In 18 days, this movement dismantled three pillars of Mubarak's regime-the security apparatus, NDP [National Democratic Party] and...the military," he said.

Samer Shehata, an assistant professor of Arab politics at Georgetown University, discussed the response of the regime to the protests and the reasons for its failure.

The second panel looked to the future, focusing on the Egyptian presidential elections scheduled for later this year. Speeches addressed the process of negotiations between the regime and opposition groups, the agenda for constitutional and institutional reform and political repression.

Panelist Jason Brownlee, an associate professor in the Department of Government at University of Texas at Austin, drew a parallel between the current situation in Egypt and the one in Russia in 1991. He described the liberal movement as "electorally weak" and said it experienced difficulty in maintaining momentum.

The third panel addressed political parties in the post-revolution landscape, including the Islamist Muslim Brotherhood party. Panelist Hesham Sallam, a doctoral candidate at Georgetown University, spoke on how the timeline for the parliamentary elections, currently set for this September, disadvantages newly formed parties and favors parties such as the Muslim Brotherhood.

"The speed of transition in Egypt  gives advantage to existing political parties by not allowing time for newcomers to organize," he said.

"The Brotherhood knows how to play politics where liberals have absolutely no idea," added Shadi Hamid, the director of research at the Brookings Doha Center.

Diamond described parallels with the situation in Iraq in 2004 and 2005.

"The liberals weren't good at organizing, had no mass constituency and got electorally crushed...but they had a constructive influence on the constitution making process," he said.

"We should look at this as an iterative process of several elections to come," he added.

The final panel focused on looking forward. Rowswell presented a new "Open Source Democracy Promotion" project, designed to provide Egyptian activists with an option for crowd sourcing constitutional negotiations.

"The best approach is for informed and engaged citizens to support the Egyptian activists...inspired by the opportunity Egyptians have given themselves but also inspired by what Egyptians have given the world regarding democratic state building and ushering in a new age of democracy based on mutual collaboration and participation," Rowswell said.

Hamid delivered the final talk of the conference, presenting his forecast for the parliamentary elections. He singled out newly formed parties backed by wealthy individuals as key players in the upcoming vote.

"The established political parties will do quite well, but also individuals with name recognition in their districts and those with resources will do well," he said.

Hamid cautioned against overly idealistic projections, given the disorganization of the liberal parties in Egypt.

"We have to be realistic," he said. "We wanted to think for a long time that once there was democracy, Egyptians would become fluffy American-style liberals, and we don't know if that is true."

"From the perspective of international actors doing democracy promotion, I think there's a distinction between encouraging Egyptians to make one choice over another," Rowswell said. "I think it should be ensuring that there is a choice to make."

On March 1, the Program on Human rights welcomed David Pressman to the Stanford campus, where he spoke during the eighth installment of the Sanela Diana Jenkins Speaker Series. Pressman, the former Chief of Staff to the Deputy Secretary of Homeland Security, was recently appointed by Obama to serve as the first-ever Director for War Crimes and Atrocities on the National Security Council at the White House.

Drawing both from his experience as an advocate during the crisis in Darfur and from his current role as a government official, Pressman discussed the challenges of making the oft-quoted promise of  "never again" a reality. Pressman argued that the United States has begun to and must continue to adopt more proactive and preventative measures to respond to humanitarian crises as they happen.

Pressman discussed his efforts to create an established process to identify areas where diplomatic efforts of the United States could help prevent or mitigate atrocities. In such a system, the NSC would collect and compile data from NGO's and intelligence agencies to analyze indicators that could predict when and where mass atrocities are likeliest to occur. With this information, the United States could better allocate its resources and engage diplomatically with other states who may be better positioned or equipped to handle the mounting crises.

Speaking more broadly about the demands of his job, Pressman said that it is an extremely exciting time to be working in his position. He detailed the government's massive efforts to prevent the outbreak of violence in the wake of the recent referendum in Sudan, which he described as a marked shift in policy focus toward prevention from the typical reactive measures of the past. He described the recent referral of Muammi Qaddafi to the International Criminal Court as a "watershed moment" for the United States' relationship with the international community in terms of human rights enforcement.

Nevertheless, he mentioned the many areas around the world in which mass atrocities are widespread - Côte d'Ivoire, Kenya, and Burma, among others -  and emphasized the need for continued progress toward a world where "never again" is more than a catch slogan.

Over the course of three short months, popular uprisings have toppled regimes in Tunisia and Egypt, sparked a civil war in Libya and created unrest in other parts of the Middle East. They also have raised a question in many people's minds: Are all authoritarian regimes now threatened by this new democratic wave? In particular, is China, a rising superpower, vulnerable to these forces?  

The Communist government in Beijing is clearly worried. It has limited news coverage of the recent uprisings and has clamped down on democratic activists and foreign reporters, acting pre-emptively against anonymous calls on the Internet for China to have its own "Jasmine Revolution." A recent front-page editorial in the Beijing Daily, an organ of the city's party committee, declared that most people in the Middle East were unhappy with the protests in their countries, which were a "self-delusional ruckus" orchestrated by a small minority. For his part, President Hu Jintao has urged the strengthening of what has been dubbed the "Great Firewall"-the sophisticated apparatus of censorship and surveillance that the regime uses to control access to the Internet.

No social scientist or intelligence analyst predicted the specific timing or spread of the Arab uprising-the fact that it would start in Tunisia, of all places, that it would be triggered by an event like the self-immolation of a vegetable seller, or that protests would force the mighty Egyptian army to abandon Hosni Mubarak. Over the past generation, Arab societies have appeared stolidly stable. Why they suddenly exploded in 2011 is something that can be understood only in retrospect, if at all.

But this doesn't mean that we can't think about social revolutions in a more structured way. Even unpredictable things take place in a certain context, and the present-day situations of China and the Middle East are radically different. Most of the evidence suggests that China is pretty safe from the democratic wave sweeping other parts of the world-at least for now.

Perhaps the most relevant thinker for understanding the Middle East today and China tomorrow is the late Samuel Huntington-not the Huntington of "The Clash of Civilizations," who argued that there were fundamental incompatibilities between Islam and democracy, but the Huntington whose classic book "Political Order in Changing Societies," first published in 1968, laid out his theory of the development "gap."

Observing the high levels of political instability plaguing countries in the developing world during the 1950s and '60s, Mr. Huntington noted that increasing levels of economic and social development often led to coups, revolutions and military takeovers. This could be explained, he argued, by a gap between the newly mobilized, educated and economically empowered people and their existing political system-that is, between their hopes for political participation and institutions that gave them little or no voice. Attacks against the existing political order, he noted, are seldom driven by the poorest of the poor in such a society; they tend to be led, instead, by rising middle classes who are frustrated by the lack of political and economic opportunity.

All of these observations would seem to apply to Tunisia and Egypt. Both countries have made substantial social progress in recent decades. The Human Development Indices compiled by the United Nations (a composite measure of health, education and income) increased by 28% for Egypt and 30% for Tunisia between 1990 and 2010. The number of people going to school has grown substantially; Tunisia especially has produced large numbers of college graduates. And indeed, the protests in Tunisia and Egypt were led in the first instance by educated, tech-savvy middle-class young people, who expressed to anyone who would listen their frustrations with societies in which they were not allowed to express their views, hold leaders accountable for corruption and incompetence, or get a job without political connections.

Mr. Huntington stressed the destabilizing power of new social groups seeking political participation. People used to be mobilized by newspapers and radio; today they are spurred to action by cell phones, Facebook and Twitter, which allow them to share their grievances about the existing system and to learn about the possibilities of the larger world. This change in the Middle East has been incredibly rapid, and it has trumped, for now, old verities about the supposed passivity of Arab culture and the resistance of Islam to modernization.

But do these remarkable developments tell us anything about the possibility for future instability in China?

It is certainly true that the dry tinder of social discontent is just as present in China as in the Middle East. The incident that triggered the Tunisian uprising was the self-immolation of Mohamed Bouazizi, who had his vegetable cart repeatedly confiscated by the authorities and who was slapped and insulted by the police when he went to complain. This issue dogs all regimes that have neither the rule of law nor public accountability: The authorities routinely fail to respect the dignity of ordinary citizens and run roughshod over their rights. There is no culture in which this sort of behavior is not strongly resented.

This is a huge problem throughout China. A recent report from Jiao Tong University found that there were 72 "major" incidents of social unrest in China in 2010, up 20% over the previous year. Most outside observers would argue that this understates the real number of cases by perhaps a couple of orders of magnitude. Such incidents are hard to count because they often occur in rural areas where reporting is strictly controlled by the Chinese authorities.

The most typical case of outraged dignity in contemporary China is a local government that works in collusion with a private developer to take away the land of peasants or poor workers to make way for a glittery new project, or a company that dumps pollutants into a town's water supply and gets away with it because the local party boss stands to profit personally. Though corruption in China does not reach the predatory levels of certain African or Middle Eastern countries, it is nonetheless pervasive. People see and resent the privileged lives of the nation's elite and their children. The movie "Avatar" was a big hit in China in part because so many ordinary Chinese identified with the indigenous people it portrayed whose land was being stolen by a giant, faceless corporation.

There is, moreover, a huge and growing problem of inequality in China. The gains from China's remarkable growth have gone disproportionately to the country's coastal regions, leaving many rural areas far behind. China's Gini index-a standard measure of income inequality across a society-has increased to almost Latin American levels over the past generation. By comparison, Egypt and Tunisia have a much more equal income distribution.

According to Mr. Huntington, however, revolutions are made not by the poor but by upwardly mobile middle-class people who find their aspirations stymied, and there are lots of them in China. Depending on how you define it, China's middle class may outnumber the whole population of the United States. Like the middle-class people of Tunisia and Egypt, those in China have no opportunities for political participation. But unlike their Middle Eastern counterparts, they have benefited from a dramatically improving economy and a government that has focused like a laser beam on creating employment for exactly this group.

To the extent that we can gauge Chinese public opinion through surveys like Asia Barometer, a very large majority of Chinese feel that their lives have gotten better economically in recent years. A majority of Chinese also believe that democracy is the best form of government, but in a curious twist, they think that China is already democratic and profess to be satisfied with this state of affairs. This translates into a relatively low degree of support for any short-term transition to genuine liberal democracy.

Indeed, there is some reason to believe that the middle class in China may fear multiparty democracy in the short run, because it would unleash huge demands for redistribution precisely from those who have been left behind. Prosperous Chinese see the recent populist polarization of politics in Thailand as a warning of what democracy may bring.

The fact is that authoritarianism in China is of a far higher quality than in the Middle East. Though not formally accountable to its people through elections, the Chinese government keeps careful track of popular discontents and often responds through appeasement rather than repression. Beijing is forthright, for example, in acknowledging the country's growing income disparities and for the past few years has sought to mitigate the problem by shifting new investments to the poor interior of the country. When flagrant cases of corruption or abuse appear, like melamine-tainted baby formula or the shoddy school construction revealed by the Sichuan earthquake, the government holds local officials brutally accountable-sometimes by executing them.

Another notable feature of Chinese government is self-enforced leadership turnover. Arab leaders like Tunisia's Zine al-Abidine Ben Ali, Egypt's Mr. Mubarak and Libya's Col. Moammar Gadhafi never knew when to quit, hanging on 23, 30 and 41 years, respectively. Since Mao, the Chinese leadership has rigidly adhered to terms of about a decade. Mr. Hu, the current president, is scheduled to step down in 2012, when he is likely to be replaced by Vice President Xi Jinping. Leadership turnover means that there is more policy innovation, in sharp contrast to countries like Tunisia and Egypt, which have been stuck for decades in the rut of crony capitalism.

The Chinese government is also more clever and ruthless in its approach to repression. Sensing a clear threat, the authorities never let Western social media spread in the first place. Facebook and Twitter are banned, and content on websites and on China-based social media is screened by an army of censors. It is possible, of course, for word of government misdeeds to get out in the time between its first posting by a micro-blogger and its removal by a censor, but this cat-and-mouse game makes it hard for a unified social space to emerge.

A final critical way in which China's situation differs from that of the Middle East lies in the nature of its military. The fate of authoritarian regimes facing popular protests ultimately depends on the cohesiveness and loyalty of its military, police and intelligence organizations. The Tunisian army failed to back Mr. Ben Ali early on; after some waffling, the Egyptian army decided it would not fire on protesters and pushed Mr. Mubarak out of power.

In China, the People's Liberation Army is a huge and increasingly autonomous organization with strong economic interests that give it a stake in the status quo. As in the Tiananmen uprising in 1989, it has plenty of loyal units around the country that it could bring into Beijing or Shanghai, and they would not hesitate to fire on demonstrators. The PLA also regards itself as the custodian of Chinese nationalism. It has developed an alternative narrative of 20th-century history that places itself at the center of events like the defeat of Japan in the Pacific war and the rise of a modern China. It is very unlikely that the PLA would switch sides and support a democratic uprising.

The bottom line is that China will not catch the Middle Eastern contagion anytime soon. But it could easily face problems down the road. China has not experienced a major recession or economic setback since it set out on its course of economic reform in 1978. If the country's current property bubble bursts and tens of millions of people are thrown out of work, the government's legitimacy, which rests on its management of the economy, would be seriously undermined.

Moreover, Mr. Huntington's scenario of rising but unfulfilled expectations among the middle class may still play out. Though there is a labor shortage among low-skill workers in China today, there is a glut of the college educated. Every year into the future, China will graduate more than seven million people from its universities, up from fewer than a million in 1998, and many of them are struggling to find work suitable to their self-perceived status. Several million unemployed college graduates are far more dangerous to a modernizing regime than hundreds of millions of poor peasants.

There is also what the Chinese themselves call the "bad emperor" problem. China's historical achievement over the centuries has been the creation of high-quality centralized bureaucratic government. When authoritarian rulers are competent and reasonably responsible, things can go very well. Indeed, such decision-making is often more efficient than in a democracy. But there is no guarantee that the system will always produce good rulers, and in the absence of the rule of law and electoral checks on executive power, there is no way to get rid of a bad emperor. The last bad emperor, commonly (if quietly) acknowledged as such, was Mao. We can't know what future tyrant, or corrupt kleptocrat, may be waiting in the wings in China's future.

The truth is that, much as we might theorize about the causes of social revolution, human societies are far too complex, and change too rapidly, for any simple theory to provide a reliable guide. Any number of observers dismissed the power of the "Arab street" to bring about political change, based on their deep knowledge of the Middle East, and they were right every year-up until 2011.

The hardest thing for any political observer to predict is the moral element. All social revolutions are driven by intense anger over injured dignity, an anger that is sometimes crystallized by a single incident or image that mobilizes previously disorganized individuals and binds them into a community. We can quote statistics on education or job growth, or dig into our knowledge of a society's history and culture, and yet completely miss the way that social consciousness is swiftly evolving through a myriad of text messages, shared videos or simple conversations.

The central moral imponderable with regard to China is the middle class, which up to now has seemed content to trade political freedom for rising incomes and stability. But at some point this trade-off is likely to fail; the regime will find itself unable to deliver the goods, or the insult to the dignity of the Chinese people will become too great to tolerate. We shouldn't pretend that we can predict when this tipping point will occur, but its eventual arrival, as Samuel Huntington might have suggested, is bound up with the very logic of modernization itself.
