Divorce proceedings bring out the worst in people. When Abdul Rahman tried to get custody of his daughters in Kabul, Afghanistan, his wife's family told the court that he was unfit to care for his children because he had converted from Islam to Christianity some 16 years ago. A zealous prosecutor, hearing of the case, charged Mr. Rahman with apostasy, a crime punishable by death under some interpretations of Islamic law. If Mr. Rahman does not repudiate Christianity, the judge in the case has said, he will get the death penalty.

Mr. Rahman's case is a discouraging illustration of the uneasy balance between the democratic norms Afghanistan's Constitution enshrines and the conservative Islamic values its judiciary upholds. On the one hand, the Afghan Constitution states that "followers of other religions are free to exercise their faith and perform their religious rites within the limits of the provisions of the law," and it requires the state to adhere to the Universal Declaration of Human Rights, which clearly protects freedom of conscience and the right to change one's religion.

On the other hand, the Constitution also says that no law can be "contrary to the beliefs and provisions of Islam," and it gives judges broad power to interpret and apply Islamic law. Several schools of Islam do indeed prescribe the ultimate punishment for those who abandon the faith. And so Mr. Rahman's case may well come down to the interpretive leanings of the court.

Moderate Islamic jurists in some countries have attempted to balance or reconcile these often-conflicting interests. In Egypt, for instance, the Islamic Research Center decreed that although apostasy may be a crime, the time period for redemption is limitless - in other words, it is up to the individual, not the state, to adhere to divine will. The former chief justice of Pakistan, which has explicit anti-blasphemy laws, has written that the death penalty for apostasy is not required by the Koran and conflicts with other Islamic values.

Afghanistan's post-Taliban judiciary, however, has shown a propensity to use Islam as a political weapon. The country's chief justice, Fazil Hadi Shinwari, is a hard-line conservative associated with the Islamist parties of Abdul Rasul Sayyaf and Burhanuddin Rabbani. He has used the court as a bully-pulpit, issuing fatwas on a variety of issues outside his jurisdiction.

For instance, under Justice Shinwari's leadership the Supreme Court has variously attempted to ban co-education; tried to eliminate a rival to President Hamid Karzai from the 2004 elections; and jailed newspaper editors, all in the name of Islam.

In other words, the court has overstepped its bounds and contributed to the radicalization of Afghan politics in the process. To further his aims, Justice Shinwari has packed the lower courts with judges who have Islamic educations but no foundation in Afghan law or experience in the judiciary.

President Karzai has a unique opportunity to change this. Under the Constitution, Mr. Karzai must appoint a new Supreme Court this month, and he sent his slate of nine justices to Parliament for approval last week. Although the current chief justice has retained his position, there are some very promising choices among the eight other justices. They include known moderates, like the former chairman of the Judicial Reform Commission, Bahauddin Baha, and the deputy minister of justice, Qasim Hashimzai, who led a major corruption investigation involving members of President Karzai's cabinet.

These appointments mark President Karzai's first opportunity to compose Afghanistan's Supreme Court under a fully constitutional government. They are of momentous importance to the country's stabilization and the consolidation of its nascent democracy.

By creating a competent, professional and moderate judiciary, President Karzai will help to establish the rule of law. If, however, the court remains in the thrall of ideology and factionalism, Afghanistan's experiment in democracy will be compromised.

But the new judges will be powerless to reform the system unless they are given the political support and resources to do so. International involvement in Afghanistan's justice sector since 2001 has been inadequate. Both the Afghan government and its donors need a strategic vision for the judiciary's future and the political focus to make it a reality.

The new judiciary will need support to review the qualifications of the lower court judges, facilities to train new judges and functioning courthouses in the provinces. It will need to be able to share information, laws and legal decisions among officials throughout the country and to pay judges a living wage.

We must do more than simply react loudly to the most extreme cases, like that of Mr. Rahman. Instead, we must partner with the Afghans and other democratic governments in the Islamic world as they struggle to promote modernity and the rule of law. This means working with judicial systems on less controversial, bread-and-butter issues like criminal law and property disputes.

We have seen throughout the world, and in our own history, that competent and independent judges will stand up for the rule of law even when their decisions indict the powerful and defend the unpopular. Mr. Rahman's case should remind us of how important it is to help Afghanistan develop such judges if we want its democracy to succeed.

There was no Orange-style revolution in Belarus following the 19 March presidential elections. But there may have been the beginning of a revolution of the spirit that will bring the last tyranny in Europe to an end. Observers should not lament the "failure" of revolution but should hail the beginning of a genuine democratic movement, which is stronger today than it was just a few years ago.

From the beginning of this campaign, there was little sign of a real contest. Lukashenka could have won a free and fair election: Strong economic growth and social stability might have guaranteed him half of the vote or so, had the vote actually been counted. But a free and fair vote carried the risk of defeat, however remote, and the ghost of the Orange Revolution in Ukraine in 2004 fueled hysteria within the regime. Consequently, just before the vote, the government criminalized opposition-related activity and began to arrest election monitors and activists from nongovernmental organizations on charges of terrorism.

Yet Lukashenka wanted some legitimacy for his reelection and therefore allowed opposition candidates to participate. Surprisingly, two challengers, the leader of the united opposition, Alyaksandr Milinkevich, and the former rector of the Belarusian State University, Alyaksandr Kazulin, refused to bow to the dictator and decided to play by their own rules. Their 30-minute campaign speeches on state TV (that is how much exposure to alternative opinions an ordinary TV viewer in Belarus has had in five years) were devoted not much to the issues but to attacking Lukashenka's character - an act previously unthinkable in a country where one official once declared Lukashenka to be "a bit higher than God." Both candidates emphasized freedom and democracy rather that day-to-day issues in their messages and found much sympathy, to the surprise of observers. Thousands turned out on the streets to hear speeches from opposition candidates, numbers that were unthinkable even in Minsk just a year ago.

Lukashenka saw the crowds as well and got nervous. Kazulin, whose particularly scathing attacks made him an instant celebrity, was beaten up by riot police. Dozens of observers and reporters were denied visas, expelled, or even arrested and charged with helping to plot a coup. State TV propped up its propaganda, and the KGB began to discover one plot after another every several days. In the last revelation, the head of the KGB claimed that the opposition would poison the tap water in Minsk using decomposing rats. And dozens of opposition activists with experience in street protests were rounded up in the run-up to the vote. Yet even in the face of these repressive tactics, Lukashenka's autocratic regime failed to deter people from mobilizing on the streets after the vote to denounce the fraudulent results.

On 19 March, at least 20,000 people took to the streets to protest the announcement of a "smashing" victory for Lukashenka, who was declared winner with 83 percent of the vote cast. And the protesters did not stop there, organizing an around-the-clock vigil on the central square of Minsk to demand annulment of the vote and new elections.

To be sure, the size of the protests was nowhere near the crowds that turned out in the streets in Kyiv a year and half ago. Yet thousands of Belarusians braved not only the blizzard but explicit threats of jail and even the death penalty made by the KGB on the eve of elections. Most of them faced immediate dismissal from state jobs or university if found in the crowd or even caught checking an opposition website. And they barely had means to communicate with each other due to suspension of most of the opposition press and an almost total blockade of the Internet and mobile communications. Could one have expected a protest of more than just a handful of dissidents in these, almost Soviet-style conditions?

SMALL VICTORIES

In retrospect, one has to admit that the protest was doomed. The opposition knew it did not win the elections and hence did not attempt to stage a revolution as such: that is, to attempt to snatch power from Lukashenka by force. Instead, the protest turned into a show of defiance, an attempt to get the sympathy and attention of fellow countrymen. Day after day, the numbers dwindled, not least because each new day brought the protesters closer to an imminent show of force by the government. It came on the morning of 23 March, when people on the square were surrounded and thrown into police trucks, then taken to jails and sentenced to various prison terms.

The dramatic end of the protest also highlighted an unpleasant fact for the Belarusian opposition: A combination of fear imposed by the government on one part society, and acceptance of the regime by another part, still limits its appeal and following. The streets of Minsk these days were full of pictures of solidarity and defiance, but also of indifference from passers-by and loathing for the protesters from the regime's supporters.

Lukashenka's opponents still have a long way to go to communicate their message to the entire society - and will have to do so in an even more repressive political climate than they have endured so far. But failures and disappointments shall not distract attraction from the opposition's successes in this campaign and afterward. It achieved unity and presented society with a leader whom many accepted as a credible alternative to Lukashenka. It invigorated the network of democratic activists, who braved certain repression and imprisonment. It spurred public debate, and the quest for free information was boosted even when the regime knocked out independent newspapers by the dozens. And it proved to the society and the entire world that support for democratic change in Belarus is not limited to just a handful of fanatics.

The March events may be the beginning of a newly invigorated fight for democracy in Belarus as much as it can trigger a new, more severe round of oppression from the regime. The West cannot stop paying attention. Those struggling for democracy, especially those already in jail, deserve our solidarity; families of political prisoners need support; and recently expanded democratic assistance programs, especially efforts to expand access to independent media within Belarus, must be sustained, not cut, now that the election is over.

Democrats in Belarus defied expectations and demonstrated that they exist, they have some popular support, and they are willing to take risks in their fight for freedom. Now, more than ever, supporters of freedom in the West need to stand with them.

Before attacking Iraq in March 2003, the United States told the world that Saddam Hussein had reconstituted his nuclear weapons program in defiance of the United Nations. That claim, used to justify the war, was based on assessments provided by the United States intelligence community. But as everyone now knows, those assessments were wrong. So Jeffrey T. Richelson's history of American nuclear intelligence, including our attempts to learn about Iraq's nuclear program, could hardly be more timely.

In "Spying on the Bomb," Richelson, the author of several books on American intelligence, has brought together a huge amount of information about Washington's efforts to track the nuclear weapons projects of other countries. He examines the nuclear projects of Nazi Germany, the Soviet Union, China, France, Israel, India, South Africa, Taiwan, Libya, Pakistan, Iran and North Korea, as well as Iraq. Through interviews and declassified documents as well as secondary works, he sets out briefly what we currently know about those projects and compares that with assessments of the time.

This may sound like heavy going, but Richelson writes with admirable clarity. And along the way he has fascinating stories to tell: about plans to assassinate the German physicist Werner Heisenberg during World War II; about discussions in the Kennedy and Johnson administrations on the possibility of attacking Chinese nuclear installations; about Indian measures to evade the gaze of American reconnaissance satellites; and about the bureaucratic infighting over the estimates on Iraq.

The United States has put an enormous effort into gathering information about the nuclear projects of other countries. After World War II it equipped aircraft with special filters to pick up radioactive debris from nuclear tests for isotopic analysis. It created a network of stations around the world to register the seismic effects of nuclear explosions. Most important, in 1960 it began to launch reconnaissance satellites that could take detailed photographs of nuclear sites in the Soviet Union and China. Richelson occasionally speculates about the role of communications intercepts and of spies, but these appear from his account to have been much less important than the other methods of collecting information.

Through these means the United States has gathered a vast quantity of data, sometimes to surprising effect. Intelligence played a crucial role in the cold war, for instance, by reducing uncertainty about Soviet nuclear forces. Alongside such successes, however, there have been failures. One notable example concerned the first Soviet test, which took place in August 1949, much sooner than the C.I.A. had predicted. Another was the failure to detect Indian preparations for tests in May 1998, even though at an earlier time the United States, with the help of satellite intelligence, had managed to learn about preparations the Indians were making and to head off their tests.

But the most serious failure of all was in Iraq in 2003, because in no other case did the intelligence assessments serve as justification for the use of military force. The information needed for avoiding political surprise is one thing. That needed for preventive war is quite another, if only because of the consequences of making a mistake.

Beyond making the uncontroversial recommendation that "aggressive and inventive intelligence collection and analysis" should continue, Richelson draws no general conclusions. That is a pity, because his rich material points to issues that cry out for further analysis. He suggests in one or two cases that failures sprang from the mind-set of the intelligence community, but he does not elaborate on this point. He has little to say about relations between policy makers and the intelligence community, even though the quality of intelligence and the use made of it depend heavily on that relationship.

His focus is no less narrow in his discussion of foreign nuclear projects. He concentrates on the programs themselves, paying very little attention to their political context. Does that reflect a technological bias in nuclear intelligence? Would, for example, the prewar assessment of Iraqi nuclear capabilities have been more accurate if it had paid more attention to the broader political and economic circumstances of Hussein's regime?

The task of intelligence has become more complex than it was during the cold war. A single dominant nuclear opponent has now been replaced by a number of nuclear states, along with states and stateless terrorists that are aiming to get their hands on nuclear weapons. Meanwhile, the technology needed for producing nuclear weapons has become easier to acquire.

Many critics believe the recent performance of the intelligence community shows it has not responded adequately to this new situation. Richelson does not have much to say on this question; nor does he discuss the likely impact of the current reforms, initiated in response to the Iraq war, on the quality of intelligence. His reticence may imply that he does not think reform is necessary. Still, it is disappointing that he does not draw on his historical survey to discuss whether new approaches are needed for dealing with nuclear threats, and, if so, what those new approaches might be.

PESD fellow Nadeja Victor presented Global Natural Gas Market and Russian Gas Supply Presentation on March 14 during the "market mechanisms of energy market regulation and ways of improving them" roundtable chaired Anantoliy Yanovskiy, Director, Department of Fuel and Energy Complex, Ministry of Industry and Energy, RF. In the meeting of the Group of Eight energy ministers the following days, the chair's statement was the following:

1. G8 Energy Ministers met in Moscow on 15-16 March 2006 in order to discuss the matters of mutual interest related to global energy security.

2. The reliable energy supply plays a key role in development of worlds economies bearing in mind that the well-being, way and quality of life of people directly depend on access to energy.

3. Ministers are aware that the 21st century is sure to witness a significant increase of the global consumption of energy, primarily by dynamically developing economies. Despite the increased presence of alternative sources in the energy mix, the fossil fuels will remain the basis of the world energy industry for at least the first half of the 21st century.

4. Ministers discussed the challenges to the global energy security, issues related to promotion of market efficiency of the fuel and energy sector. We note that meeting energy security challenges will require reliance on market-oriented approaches aimed at increasing energy supply and stemming growth in demand, while encouraging market-based pricing, competition, energy efficiency, and conservation.

5. Ministers point out the importance of further development and strengthening of dialogue among energy producer, transit and consumer countries, including information exchange on the current situation as well as medium- and long-term plans and programmes of development of their respective energy sectors.

6. Ministers confirm our support for appropriate international initiatives such as the Joint Oil Data Initiative aimed at greater accessibility and transparency of data on reserves, demand and supply, stocks and production capacities.

7. Ministers note that a stable future of the international energy sector requires significant investment in the production, transportation and processing of energy resources. We recognize that to attract investment it is essential for countries to have open and favourable investment regimes including stable and predictable regulations, clear tax laws, and efficient administrative procedures as well as fair and reciprocal access to markets along the energy value chain.

8. Ministers favour the implementation of the Action plan adopted last year by our leaders in Gleneagles which includes a wide range of measures to promote innovations, increase energy efficiency and enhance environmental protection.

9. Ministers proceed from the fact that diversification of the energy portfolio in terms of energy sources, suppliers and consumers as well as delivery methods and routes will reduce energy security risks not only for individual countries but for the entire international community. Joint efforts of the G8 and other countries aimed at wider use of renewable and alternative energies, development and implementation of innovative energy technologies and development of low-carbon energy would contribute substantially to the solution of this strategic task. For those countries that wish, wide-scale development of safe and secure nuclear energy is crucial for long-term environmentally sustainable diversification of energy supply.

10. Ministers agree that continued international cooperation to develop the low carbon technologies of the future will be crucial. Facilitating development and deployment of innovative energy technology solutions will have longer term environmental, economic and energy security benefits and be key to a global sustainable energy future.

11. A significant reduction of the gap in energy supply between developed and undersupplied less-developed countries is a major aspect of global energy security.

Stanford, California - If the deal to supply India with nuclear technologies goes through, future generations may remember it for quite different reasons than the debate over nuclear proliferation.

Nuclear power emits no carbon dioxide, the leading cause of global warming. And India, like most developing countries, has not been anxious to spend money to control its emissions of this and other so- called greenhouse gases.

India is embracing nuclear power for other reasons - because it can help the country solve its chronic failure to supply the electricity needed for a burgeoning economy. But in effect, the deal would marry their interest in power with ours in protecting the planet.

India is growing rapidly. In recent years its economy has swelled at more than 7 percent per year, and many analysts believe it is poised to grow even faster in the coming decade.

The economic growth is feeding a voracious appetite for electricity that India's bankrupt utilities are unable to satisfy. Blackouts are commonplace. Farmers, who account for about two-fifths of all the power consumed, can barely rely on getting power for half of every day. In industrial zones, the lifeblood of India's vibrant economy, unstable power supplies are such trouble that the biggest companies usually build their own power plants.

So most analysts expect that the demand for electricity will rise at about 10 percent a year. (For comparison, U.S. power demand notches up at just 2 percent annually.)

Over the past decade, about one third of India's new power supplies came from natural gas and hydro electricity. Both those sources have been good news for global warming - natural gas is the least carbon- intensive of all the fossil fuels, and most of India's hydroelectric dams probably emit almost no greenhouse gases.

However, the bloom is coming off those greenhouse-friendly roses. New supplies of natural gas cost about twice what Indians are used to paying, and environmental objections are likely to scupper the government's grand plans for new hydro dams.

That leaves coal - the most carbon-intensive of all fossil fuels. Already more than half of India's new power supplies come from coal, and that could grow rapidly.

Traditionally, the coal sector was plagued by inefficiencies. State coal mines were notoriously dangerous and inefficient. Coal-fired plants in western provinces, far from the coal fields and vulnerable to the dysfunctional rail network, often came within days of shutting operations due to lack of coal.

All that is changing. Private and highly efficient coal mines are grabbing growing shares of the coal market. Upgrades to the nation's high-tension power grid is making it feasible to generate electricity with new plants installed right at the coal mines.

These improvements make coal the fuel to beat.

So the deal struck with President George W. Bush matters. At the moment, India has just 3 gigawatts of nuclear plants connected to the grid. Government planners envision that nuclear supply will grow to 30 GW over the next generation, but that will remain a fantasy without access to advanced nuclear technologies and, especially, nuclear fuels - such as those offered under the deal with the Bush administration.

By 2020, even after discounting for the government's normal exuberance in its forecasts, a fresh start for nuclear power could increase nuclear generating capacity nearly ten-fold.

By displacing coal, that would avoid about 130 million tons of carbon dioxide per year (for comparison, the full range of emission cuts planned by the European Union under the Kyoto Protocol will total just 200 million tons per year).

The effort, if successful, would eclipse the scheme under the Kyoto Protocol, known as the Clean Development Mechanism, that was designed to reward developing countries that implement projects to reduce their emissions of greenhouse gases. The largest 100 of these CDM projects, in total, won't reduce emissions as much as a successful effort to help India embrace safe nuclear power.

The benefits in slowing global warming are not enough to make the deal a winner. Care is needed to tame the risks of proliferation, especially those connected from India's system of breeder reactors that make more weapons-capable fuel than they consume. And complementary efforts, led by Indians, are needed to fix the trouble in India's electricity sector that have so far discouraged private investors.

None of this will be easy. There are no silver bullets in cooling the greenhouse.

What is important is that the deal is not just a one-off venture, as the administration's backers, on the defensive, have suggested. It could frame a new approach to technology sharing and managing a more proliferation proof fuel cycle that, in turn, will multiply the benefits of a cooler climate.

Coal-rich China is among the many other countries that would welcome more nuclear power and whose emissions of carbon dioxide are growing fast - even faster than India's.

Quite accidentally, it seems, the Bush administration has stumbled on part of an effective strategy to slow global warming. Now it should marry that clever scheme overseas with an effective plan here at home.

The nuclear deal reached during President Bush's recent visit to India unleashed a predictable wave of criticism. From editorial and op-ed pages to Congress, led by the left but supported on the right, the administration has been assailed for making a bad bargain.

Under the agreement, which still needs congressional approval, India would open much of its nuclear facilities to international inspections in return for gaining access to the world's supplies of uranium and U.S. nuclear expertise.

The attacks on the deal reflect the view of the nonproliferation lobby -- the experts and policymakers whose central concern is to stop the spread of nuclear weapons. I share their aim. But American arguments against the India deal are misleading and only expose the deep contradictions, if not hypocrisy, of our own nuclear policies.

There are two main criticisms of the agreement: first, it undermines the Nuclear Nonproliferation Treaty, the NPT, and second, it permits, even encourages, India to expand its nuclear weapons production.

The NPT issue is particularly sensitive at a time when the international community is trying to persuade Iran to give up certain nuclear technologies which many nations fear are part of a secret bomb program.

The NPT created two sets of global rules -- one for the five nuclear weapons powers it recognizes (China, the United States, Russia, Britain and France) and another for everyone else. The five, for example, allow only "voluntary'' international safeguards on their civilian nuclear facilities. They have no obligation to open their military programs to any kind of scrutiny. And the NPT places no real limits on their arsenals, other than a vague commitment to reduce and eventually eliminate all nuclear weapons.

The rest must open their nuclear energy programs fully to international inspection and agree never to build bombs. In exchange, they gain access to the peaceful uses of nuclear energy.

Iran -- and North Korea -- made that bargain and can be held to account for breaking the rules. But India consistently regarded that as an unequal trade-off and never signed the NPT; neither did Pakistan and Israel, two other nuclear weapons states.

India's nuclear program is the product of decades of largely indigenous effort; it did not result from secretive proliferation in violation of the NPT.

The deal with India turns the five into six. It treats India as a de facto member of the inner club. The deal would require changes in U.S. law to remove existing restrictions on the transfer of nuclear energy technology, changes that would allow India to be treated no differently from China.

That does not weaken the NPT -- it strengthens it. It brings it more into accord with reality and gives India a stake in a system it had previously rejected as unfair. It paves the way for India to join the Nuclear Suppliers Group, the international organization that controls nuclear exports.

The critics are right that the deal enables India to expand its production of fissile materials to make nuclear warheads. Eight of India's 22 power reactors will remain outside international controls, along with a new breeder reactor. The Indians fought for that exemption because they feel their nuclear arsenal may not be large enough to deter a nuclear first strike by Pakistan or China in the future. Critics fear that with increased access to uranium and limited inspections, India will set off an arms race in South Asia.

Again, the agreement simply treats India like the five. Nonproliferation experts claim that unlike India, however, the five have halted their production of plutonium and highly enriched uranium that could be used to build new weapons. This is true, but misleading.

The five have massive stockpiles of fissile material built up during the Cold War. "If I've got a full pantry, it's easy for me to swear off trips to the supermarket,'' said Michael Levi, an arms-control expert at the Council on Foreign Relations.

Moreover, the United States has embarked on a new program to rebuild its nuclear weapons production capability, including creating new facilities to produce plutonium cores for warheads and to assemble them.

India has agreed to back a global pact to cut off fissile-material production. But the Bush administration does not support a treaty that would actually verify this is taking place. And the U.S. Senate has refused to ratify the Comprehensive Test Ban Treaty that would permanently halt any new testing of nuclear weapons.

A Congress that can support those policies is hardly in a position to challenge the administration's agreement with India. Rather than block the U.S.-India deal, it makes more sense to improve it. This could include reaching agreements for cooperation between the two countries to ensure the safety and security of nuclear facilities, including those for military purposes, suggested Stanford Professor Scott D. Sagan, a leading expert on nuclear safety and nonproliferation. "Reducing the risk of terrorist theft of nuclear materials or weapons in India would also help protect the United States,'' argues Sagan.

Beyond that, the six acknowledged nuclear powers should begin to seriously fulfill their part of the NPT bargain -- to cap fissile-material production, to ban nuclear testing, and to eventually radically reduce stored arsenals of nuclear weapons and materials.

It is time to acknowledge that the international community's strategy on Zimbabwe has failed.

Robert G. Mugabe's regime has survived even as the economy deteriorates further (unemployment is above 70 percent, and gross domestic product will decline another 7 percent this year) and personal freedom suffers greater assaults (the recent "drive out the rubbish" campaign left 700,000 people homeless).

Indeed, with the opposition Movement for Democratic Change (MDC) on the verge of collapse - following a bitter fight over whether to boycott the recent Senate elections and after years of sustained government pressure - the regime has a stronger grasp on power than ever. Doddering though he may be, Mr. Mugabe, who recently turned 82, has foiled the pressure of the United States and Britain and the quiet diplomacy of his neighbors in southern Africa.

Predictions of imminent change still crop up in Western newspapers on the occasion of every new crisis in Zimbabwe. But these predictions have not come to bear, and they likely will not. So long as Mr. Mugabe reigns, his Zimbabwe African National Union-Patriotic Front (ZANU-PF) regime will survive.

The international community tried to change things. It embarked on a strategy of concerted economic and diplomatic pressure to weaken the Mugabe regime, trying to force it to either back down or submit to the democratic opposition. It's clear that strategy has failed.

It is, therefore, time to focus international attention on the prospect of Zimbabwe's only genuine political opening in the years ahead: the exit of Mr. Mugabe, whether through retirement or death, which will leave the regime internally and externally vulnerable.

Internally, the ZANU-PF regime without Mr. Mugabe at the helm will be uniquely susceptible in an election. In sub-Saharan Africa, opposition candidates have won post-transitional elections only 5 percent of the time against incumbents but 33 percent of the time against regimes' designated successors.

The most important reason for that is the incumbent's exit removes the regime's glue. The regime fractures into competing factions and is left with a substantially reduced capacity to repress the political opposition and rig an election.

In Kenya, after President Daniel T. arap Moi, and in Ghana, after President Jerry J. Rawlings, the regimes did not - could not - resort to all the dirty tactics that they certainly would have used had the incumbents run. In turn, these political openings have tended to galvanize the fractured opposition to successfully cooperate.

A ZANU-PF that is deeply unpopular, badly fractured among ethnic groups and between moderates and hard-liners (the expulsion of the information minister, Jonathan Moyo, is the beginning) and facing a reinvigorated opposition will not likely be able to effectively rig elections, let alone win the popular vote.

It will be critical, then, that presidential elections be held within a year of Mr. Mugabe's exit, before the regime has too much time to consolidate. If Mr. Mugabe's exit does not occur within that window before the 2008 elections, then international, and particularly regional, pressure will be crucial in forcing early elections.

Externally, Mr. Mugabe's exit may prompt genuine regional pressure. Analysts have long emphasized that international pressure requires the support of Zimbabwe's neighbors - especially South Africa - that have significant political and economic leverage. But to the great frustration of Western governments, southern African countries have thus far refused to publicly challenge Mr. Mugabe.

Their reluctance has much to do with Mr. Mugabe's status as a hero of Zimbabwe's anti-colonial struggle and a champion of liberation struggles elsewhere. Southern African nations will have much greater political room to apply real pressure on Zimbabwe when its leader lacks such credentials.

Simultaneously, the prospect of an altogether different level of violence might shake the complacency of southern African nations. Zimbabwe's implosion has not, thus far, been entirely bad for its neighbors. They have benefited from the elimination of economic competition and from the influx of professionals, and they have retained confidence that Mr. Mugabe can keep control.

But there is a real danger, if a post-Mugabe Zimbabwe is not handled adroitly, that elements of the opposition, disaffected war veterans and youth militia and losers in the ZANU-PF factional battle will take up arms and plunge Zimbabwe into civil war.

This specter should push neighboring countries to step up their efforts, especially to press the post-Mugabe regime to hold new presidential elections and encourage moderate elements within ZANU-PF.

Notwithstanding its occasional fulminations against Zimbabwe, the United States has failed in its efforts to unseat Mr. Mugabe's regime. The United States should focus now on his eventual exit by helping the MDC to overcome its bitter infighting and engaging Zimbabwe's neighbors, especially South Africa, in vigorous diplomacy, pushing them to prepare for the occasion.

The stakes could not be higher, for if the post-Mugabe period is the first genuine opportunity for political change in Zimbabwe, it may also be the last for some time.
