The European Forum at the Freeman Spogli Institute for International Studies at Stanford University had an eventful and exciting 2005-06 academic year. We organized almost thirty seminars, workshops and other events on cultural, economic and political issues affecting Europe, its relations with the United States and its role in the world.

We hosted several prominent politicians and diplomats during the academic year. In October John Bruton, European Union Ambassador to the United States and former Prime Minister of Ireland (1994-97), presented his views on Europe and the United States as global partners. Earlier during the Fall we were honored to welcome Latvian Foreign Affairs Minister Artis Pabriks. He gave a lecture on Latvia's current challenges in foreign policy and homeland security.

During the Winter term Estonian President Arnold Rüütel visited Stanford. In his talk he addressed such issues as Estonia's relations with the United States, the European Union and Russia. Andras Simonyi, Hungarian Ambassador to the United States, also visited the European Forum. He presented a fascinating lecture on the political and economic situation in Hungary two years into its EU membership. Three more diplomats gave talks during the Winter Quarter. Kurt Volker, Principal Deputy Assistant Secretary of State for European and Eurasian Affairs, spoke about the United States, Europe and the broader Middle East. Dominic Martin, Counsellor at the British Embassy in Washington, talked about the United Kingdom and its current challenges and opportunities in world politics. Richard Morningstar, former United States Ambassador to the European Union, Lecturer at the Stanford Law School and European Forum Research Affiliate, presented his insights into the cooperation between the United States and the European Union in counter-terrorism. This last seminar was part of a series of events the European Forum organized on the manners in which European countries and institutions are dealing with the threat of terrorism, following the attacks in Madrid and London.

The War on Terror was also among the issues addressed by Joschka Fischer, former German Foreign Minister (1998-2005). He visited the Freeman Spogli Institute for International Studies in April and gave a 2006 Frank E. and Arthur W. Payne Distinguished Lecture for a standing room only crowd at the Bechtel Conference Center at Encina Hall. He talked about Europe's prospects in a globalized world and the future of transatlantic relations. British Ambassador Sir David Manning gave an equally well-attended and equally impressive 2006 Frank E. and Arthur W. Payne Distinguished Lecture on energy as a burning issue in foreign policy.

Other events organized on the topic of counter-terrorism included a round-table discussion on anti-terrorism finance, by Jacob Shapiro, Laura Donohue and Khalid Medani, all affiliated to Stanford University, and a lecture on the French experience of counter-terrorism by Jeremy Shapiro from the Brookings Institution. The series of events culminated with a lecture and a seminar by prolific author and columnist Christopher Hitchens. During a visit to the European Forum in May he presented his fascinating and thought-provoking views on the war on terror, and the situation in Iraq and Iran. The series of events on terrorism is to continue during the next academic year and will culminate with a Thinking Terrorism conference in late 2007.

Furthermore, we organized a number of events on other political issues. German sociologist Heinz Bude, from the University of Kassel, presented his views on the most recent German elections from a broad, societal and historical perspective, paying attention to the 1968 student uprisings and their long-term impact on German society. Christian Deubner, from the CEPII research center in Paris, shared his opinions on current developments in French politics, with a focus on the French rejection of the EU Constitution earlier this year and its impact on France's position in the EU. German author Peter Schneider offered his reflections on the cultural differences between Europe and the United States. He compared the relationship between the two continents to a marriage that has its ups and downs, but endures. Josef Joffe, Editor of the German newspaper Die Zeit, pointed at cultural, demographic, political and economic reasons to argue that the European Union is not about to become a new superpower.

Ken Kollman, from the University of Michigan, presented a political-economic model of leadership in federations and applied it to the EU. Bert Martens, an economist at the EU Commission in Brussels, presented an analysis of the EU's export of political and economic institutions to its neighboring countries, and the incentives it provides for regime change. Markus Hadler, a sociologist at the University of Graz and visiting professor at the European Forum during the past academic year, offered an appraisal of democracy in Europe.

Simon Hug, from the University of Zürich, presented a political-economic model of the negotiations for an EU constitution. Yaron Deckel, from the European Broadcasting Service, talked about the most recent Israeli Elections. Cas Mudde, from the University of Antwerp, presented a talk on immigration and the success of populist parties in the Low Countries. Piet Jan Slot, from Leiden University, gave a seminar on the EU's plans for an internal market for services.

We also organized a number of seminars dealing with various aspects of World War II and its aftermath. There was a talk on the effects of the Europeanization of the holocaust on the attitudes toward Jews, by Werner Bergmann from the Technische Universität Berlin. Monica Siegel, from California State University, Sacramento, gave a presentation on memory and reconciliation in France and Germany. Richard Evans, from Cambridge University, talked about coercion and consent in Nazi Germany. Wolfgang Eichwede, from the University of Bremen, gave a seminar on the dissident movement and Samizdat culture in Eastern Europe. Holocaust survivor Leopold Engleitner and his biographer Bernhard Rammerstorfer talked about surviving Buchenwald as a Jehova's Witness. Martina Pottek, from Bonn University, gave a presentation about artistic concepts to commemorate the holocaust.

Andreas Dorschel, Professor at the University of Graz, and Visiting Austrian Chair Professor at the European Forum during the past academic year, presented a lecture on Bruckner and the 19th century fates of origin.

As the next academic year draws near, we anticipate many more prominent speakers to visit the European Forum. Included in our schedule is the Europe Now lecture featuring Daniel Cohn-Bendit in November 2006.

The nuclear regime in place since the Nonproliferation Treaty (NPT) took effect in 1970 is broken and needs to be fixed, the world's highest-ranking nuclear official told a half-full Memorial Auditorium in a wide-ranging lecture about the future of nuclear energy and weapons yesterday afternoon.

"We have a dysfunctional system -- system that cannot endure," said Mohamed ElBaradei, the director general of the International Atomic Energy Agency (IAEA). "We're reaching the fork in the road. Events in the last few years have made it clear that we need to change course."

The big news from ElBaradei's speech was his support for American entreaties to Iran. But the 2005 Nobel Peace Prize recipient also commented on North Korea, India, Pakistan, Iraq, terrorism, disarmament and the future of nuclear energy.

He said there are probably eight current nuclear states, excluding North Korea. He worried aloud that countries which can currently produce nuclear energy peacefully are only six months away from developing nuclear weapons for military purposes.

"Acquiring the technology to enrich uranium or reprocess uranium basically is the key to develop nuclear weapons as we have seen in Asia and Iran," he said. "They are virtually weapons states because in six months time if they decide for security reasons to develop their own weapon, they are there."

Iraq

While not a household name, ElBaradei was a prominent figure in the news as the lead weapons inspector in Iraq during the run-up to the 2003 American invasion. He said at the time that he could not find evidence of Iraqi weapons of mass destruction, but he would not conclude that there were no weapons in the country or that Saddam Hussein did not have a program.

ElBaradei asked for more time to complete inspections, but the Bush administration declined his request and decided to invade. The U.S. never found the nuclear and biological material that some had promised existed.

"Luckily...well I'm not sure luckily...we were proven right that there was no nuclear or any weapon of mass destruction in Iraq," he said. "But I hope that all of us have learned from the Iraq experience that we cannot just jump the gun. You have to be absolutely sure of the facts."

India

ElBaradei surprised observers when he supported the U.S. agreement with India earlier this year, which allowed the country to continue developing nuclear weapons and energy. He said the agreement with India did not endorse its proliferation activities but was indicative of the kind of outside-the-box thinking the international community needs when considering the spread of nuclear weapons and material.

"The end result is India coming closer and working with the rest of the world," he said. "It is not a perfect agreement, but it has a lot of advantages. From the safety, security and nonproliferation perspective, I see that agreement as a win-win situation."

Pakistan

Pakistan developed nuclear weapons as a response to India. Some have criticized Pakistan for its poor stewardship and control of the bomb, pointing out that weapons were almost fired during a skirmish over the disputed Kashmir region.

AQ Kahn, a senior nuclear scientist who helped Pakistan join the exclusive nuclear club, was caught selling compact discs and other information about bombs to several other countries.

"How much damage was done in the process we don't know," ElBaradei said.

The release of this nuclear material demonstrates the need for a "more robust verification system," he said, adding that Pakistan has come closer to the international community in recent years.

North Korea

Kim Jong Il expelled all IAEA inspectors in Dec. 2002, withdrew from the NPT in Jan. 2003 and announced in February 2005 that his military had a nuclear deterrent.

"North Korea is still a major problem," ElBaradei said. "We don't talk about it enough, but North Korea is declaring right now that they have a nuclear weapon. And the longer that they continue to be in that status, the more it is accepted in the collective conscious. This would be terrible because it will have a lot of negative ramifications in South Korea and Japan."

ElBaradei said ongoing negotiations are an important development but more needs to be done.

"What we see with the current six-party talks should have taken place years ago," he said.

Nuclear Proliferation

ElBaradei stressed that he understands the value of nuclear power, which produces much of the developed world's energy. Reducing its use would create more dependence on greenhouse gas-creating fossil fuels, he said.

"We need to use nuclear energy responsibly to maximize benefit and minimize risk," he said.

He said his "number one nightmare scenario" is a terrorist group acquiring nuclear technology since terrorists are not deterred by the possibility of reprisal.

In the post-Cold War world, ElBaradei said he could see no justification for the U.S. and Russia to maintain their nuclear arsenals on ready alert to fire with thirty minutes notice. He called on America to lead by example and continue to disarm its nuclear stockpile.

"Rather than pass judgment, I'd definitely like to say the U.S. should do more in leading by example in terms of nuclear disarmament," he said.

In September 2005, ElBaradei was reappointed to a third term as director general of IAEA. The United States had considered holding up his nomination but dropped its objections under pressure from European allies, who admire the former law professor from New York University.

Diplomat to the Core

The Egyptian native's sometimes broken English was interspersed with self-corrections and careful legalese nuance. ElBaradei answered questions posed by Political Science Prof. Scott Sagan, the director of the Center for International Security and Cooperation.

When Sagan made bold pronouncements about different country's nuclear activities, including the United States' "colossal failure" when North Korea violated the NPT, ElBaradei seemed careful not to point fingers, play the blame game or make enemies. Nonetheless, for a senior United Nations official, his speech was notably blunt.

"There's no international public servant whose integrity and work I admire more than yours," Sagan told ElBaradei.

Accompanied by his wife, ElBaradei spent the day at the University visiting with faculty and students. He spoke at a lunch sponsored by the Freeman Spogli Institute for International Studies and traveled to Sagan's home for a dinner with invited guests. He left the area at 8:30 p.m.

Iran has climbed to No. 1 on the Washington crisis hit parade. The question of how to stop Iran's nuclear program has unleashed a torrent of punditry. Advocates of diplomacy and a military strike spar on television and in op-ed pages.

Iran's nuclear ambitions deserve our attention. But even by the most alarmist estimates, Iran is years away from being able to build a nuclear warhead.

Meanwhile, over in Northeast Asia, North Korea now has enough fissile material for five to seven weapons and is quietly churning out enough plutonium to build at least one warhead a year, according to rough intelligence estimates. More ominously, work is moving ahead on a new reactor that could potentially produce enough separated plutonium for up to 10 weapons a year.

Somehow this danger prompts no sense of urgency in Washington. After a promising breakthrough last September, the six-party talks to halt the program have lapsed into a stalemate that is close to total collapse.

The Bush administration seems unconcerned. Diplomacy has ground to a halt. The North Koreans refuse to return to the six-party talks. The White House has barred its chief negotiator from talking directly with them, despite Pyongyang's desire to meet and the urging of our six-party partners.

Administration officials have recently floated a report that they are considering a new initiative to negotiate a peace treaty with North Korea. This is a smoke-screen to conceal an empty North Korea policy. According to administration officials, the peace treaty idea has been kicking around for months without going anywhere. South Korean officials tell me that they have been waiting, so far in vain, for any serious detailed discussion of this proposal.

It is the president himself who opposes direct negotiations with Pyongyang, over anything, including a peace treaty. He sees direct talks with North Korea or Iran as an act of weakness. "Somehow,'' he said last month, "the world ends up turning the tables on us.''

In reality, the administration is content to pursue a strategy of going after North Korean counterfeit currency and production of amphetamines and cigarettes, hoping to cut off the flow of funds from these activities. According to administration officials, Under Secretary of State Robert Joseph, the driving force behind this policy, gleefully talks about ``turning out the lights'' in Pyongyang.

Administration officials claim they are drying up slush funds that North Korean dictator Kim Jong Il uses to buy the loyalty of his subordinates. Some even suggest this could trigger a coup against Kim, with the Chinese pulling the strings.

But American intelligence experts who monitor North Korea closely see little evidence to support the conclusion that North Korea is being brought to its knees. Even if the measures are drawing blood, it is self-delusional to believe that this will bring down a regime that has already proven it is willing to starve its own population to stay in power.

The administration seems intent as well on pressing China and South Korea to curb their trade and investment with the North. The administration's special envoy on human rights in North Korea, Jay Lefkowitz, seems to spend most of his time attacking the South for setting up an industrial park in Kaesong in the North. He portrays it as exploiting slave labor. The South Koreans defend it as a vehicle to bring capitalism into the communist North.

The Bush administration's combination of attempted coercion and diplomatic freeze has only two visible effects so far.

First, it lends credence to North Korean claims that the United States, contrary to the joint statement issued last September, is still intent on overthrowing their regime.

Second, it undermines gains made by allowing chief envoy Christopher Hill to hold direct talks with his North Korean counterparts. That demonstrated a flexibility and confidence that disarmed critics, particularly in South Korea, and isolated the North. It strengthened coordination with China and South Korea, the two players with the most leverage over the North.

Now officials in both those capitals again question American readiness to seriously negotiate. Beijing and Seoul are even more convinced that pushing market reforms is the only route to bring the North to give up its nuclear option. Next month former South Korean President Kim Dae Jung will revisit his historic summit with the North Korean leader in 2000.

This growing gap with our allies and partners is deadly. Even if we wanted to opt for coercion, the United States can't do so alone. For that reason, it is urgent that the United States regains the diplomatic upper hand.

The world's energy system seems to have come unhinged. Oil is trading at record high prices because demand keeps rising even as supplies become unreliable. Oil exporters from Iran to Russia and Venezuela are using their petrocash to pursue agendas that undercut western security and interests. Supplies of natural gas also seem less secure than ever.

The world's energy system seems to have come unhinged. Oil is trading at record high prices because demand keeps rising even as supplies become unreliable. Oil exporters from Iran to Russia and Venezuela are using their petrocash to pursue agendas that undercut western security and interests. Supplies of natural gas also seem less secure than ever.

The root cause of these troubles is dysfunctional energy politics. The countries with the strongest incentives to cut their vulnerability to volatile energy markets - notably America - are unable to act because influential politicians view all serious policies as politically radioactive. Efforts to boost supply have little leverage because the most attractive geological riches are found mainly in countries where state-owned companies control the resources and outsiders have little clout. Thus, the current energy debates are generating a volcano of proposals that have no positive impact on tight markets.

Yet these structural barriers to serious policy remain hidden because the debate labours under the meaningless umbrella of "energy security". Proper policy on oil and gas must start with the distinct uses for these fuels - each requiring its own political strategy.

The effort on oil must focus on transportation. Vehicles and aircraft work best with liquid fuels that can store large quantities of energy in a compact space and flow easily through pipes to engines. Searching for a better substitute is worthwhile, but the effort faces an uphill battle. With today's technologies, no other energy liquid can reliably beat petroleum. Liquids can be made from coal, as South Africa and China are doing. But that approach is costly and has unattractive environmental implications. Brazil and the US have focused on ethanol, which they distill from sugar or grain from crops. However, those programmes, which account for less than 0.5 per cent of the world's energy liquids, have a negligible impact on the oil market. Yet, America is redoubling its ethanol effort because it is politically unbeatable to reward corn growers and grain handlers who are a formidable force in US politics. Indeed, requirements for ethanol in America have created a more rigid fuel supply system that actually raises the price of oil products, although ethanol's backers originally claimed they would cut energy costs. That same political force also blocks imports of cheaper Brazilian ethanol. In principle, a better approach is so-called "cellulosic ethanol", which promises lower costs as it converts whole plants into ethanol rather than just the grain. But like most messiahs, its attraction lies in the future. So far, nobody has made the system work at the scale of a commercial refinery.

The best way to temper oil demand today is by lifting efficiency. Even this economic winner is politically difficult to implement. The US, which consumes one-quarter of the world's oil, has not changed fuel efficiency standards for new cars in 16 years. Every big economy - even China's - has stricter fuel economy rules than America's. Political gridlock has stymied even modest proposals to allow trading of efficiency credits. A trading scheme is politically inconvenient as it could force US carmakers (which make generally inefficient cars) to buy valuable credits from foreign brands. No politican wants to multiply Detroit's problems.

Even better ideas - such as a stiffer petrol tax - stay stuck on opinion pages of newspapers and in academic journals. Despite what is increasingly termed today's "energy crisis", these ideas barely cross the lips of politicians who want to remain viable among the thicket of anti-tax conservatives and pro-Detroit lobbyists.

The approaches needed for natural gas are quite different. In western Europe, which has long depended on imported gas from Russia, Algeria and a few smaller suppliers, the vulnerabilities are particularly stark. In principle, though, gas dependencies are easier to manage than oil because gas has rivals for each of its major uses. In electric power generation, countries must preserve diversity - ensuring, for example, that advanced coal and nuclear technologies remain viable. While "diversity" is motherhood in energy policy, in reality it requires difficult choices. In continental Europe, for example, policy-­makers have not seriously confronted the conflict between the need for diversity while, at the same time, opening the power sector to morecompetition. Historically, companies in competitive power markets have invested heavily in gas because gas plants are smaller and require less capital than coal or nuclear plants.

Gas suppliers who dream of extending their powers forget that it is harder to corner gas markets when users have a choice. Algeria learnt that lesson in 1981 when it left a key pipeline empty in a pricing dispute with Italy - extracting a better price at the time but losing billions of dollars for the future by destroying its reputation as a reliable supplier.

That lesson should be sobering for Russia today. In December, Gazprom, Russia's giant state gas company, cut deliveries to Ukraine, which then siphoned supplies that flow on to Europe. The company rattled its pipes again last month - threatening retaliation if Europe dared try to wean itself from Russia's gas. While Gazprom's management must pander to Russian nationalism (where pipe-rattling is welcome), the company's long-term viability rests on its reliability as a supplier to lucrative west European markets. Similarly, the recent decision by Evo Morales, Bolivia's president, to nationalise his country's gas fields will give him a boost domestically and might generate some instant extra revenue, but it will also encourage his customers in Brazil and Argentina to look elsewhere for energy.

"Resource nationalism" is back in vogue. But for gas suppliers in particular, it usually ends badly - not least because the infrastructure is costly to build and buyers can afford to be choosy. Gas users can further subdue Russia's rattling by multiplying sources of supply. A robust market for liquefied natural gas will help.

The tendency for gridlock in energy politics means that policymakers must focus where tough decisions matter most, such as efficiency in the use of oil and diversity in the application of gas. Yet, prospects for serious policy are poor - not least because the US, which should be a leader, is the most hamstrung. Luckily, the markets are responding on their own - albeit slowly and patchily. Costly oil is encouraging conservation and new supplies; LNG is accelerating, and gas buyers are more wary of Russian gas than they were a decade ago when Russia was seen as a reliable supplier. If the political structure remains dysfunctional on matters of energy, then the best second is perhaps no policy at all.

The Brazilian government is declaring victory in its decades-long struggle to become self-sufficient in the supply of oil. The milestone is cause for celebration in a country that has long paid a high price for imported energy.

It will also reverberate here in the United States where policy-makers, too, are trying to wean the nation from costly imports, jittery markets and the foreign spigot. But we must learn the right lessons. Brazil's success came not from treating oil as an addiction but by producing even more of the stuff and by becoming even more dependent on world markets

Here in the United States, most attention to Brazil's fuel supply has focused on the country's aggressive program to replace oil with ethanol that is made by fermenting homegrown sugar. American newspapers are filled with stories about Brazil's famous "flex fuel" vehicles that make it easy to switch between ethanol and conventional gasoline.

Guided partly by Brazil's apparent success, American policy-makers are crafting new mandates for ethanol, and flex fuel vehicles are now taking shape. We have the impression that ethanol is king.

In reality, ethanol is a minor player in Brazilian energy supply. It accounts for less than one-tenth of all the country's energy liquids.

The real source of Brazil's self-sufficiency is the country's extraordinary success in producing more oil. After the 1970s oil shocks, when Brazil's fuel import bill soared, the government pushed Petrobras, the state-controlled oil company, to look asunder for new energy sources.

Petrobras delivered, especially at home, where the firm pioneered the technologies that make it possible to extract oil locked in sediments under the seabed in extremely deep water. In the middle 1970s Brazil struggled to produce just 180,000 barrels of oil per day while importing four times that amount. Today it produces about 2 million and is self-sufficient. Indeed, the current milestone of self-sufficiency arrives with the inauguration of Brazil's newest deep water platform, the "P50." When P50 reaches its full output later this year, that one platform will deliver more liquid to Brazil than the country's entire ethanol program.

Brazil's self-sufficiency offers three lessons for U.S. energy policy:

-First is that ethanol, with current technology, will do little to sever our dependence on imported energy. Today's approach involves growing a crop - sugar in Brazil, corn in the United States - and then fermenting the fruits to yield fuel. Sugar plants in Brazil's climate are a lot more efficient at converting sunlight to biomass than is corn in the Midwest, but U.S. policy nonetheless favors corn (and imposes tariffs on imported sugar) because the program is really a scheme to deliver heartland votes rather than a commercially viable fuel.

Yet, even with Brazil's favorable climate and sugar's inviting biology, ethanol is already reaching the limit. That's because the land and other resources devoted to ethanol can be put to other uses such as growing food and cash crops.

Indeed, today the Brazilian government is actually reducing the share of ethanol that must be blended into gasoline because sugar growers prefer to make even more money by selling their product as sugar on the world market rather than fermenting it into alcohol.

New technologies - notably "cellulosic biomass"- could breathe fresh life into ethanol and replace still more oil. Cellulosic biomass is intriguing because it cuts costs by allowing the entire plant - the cellulose in the stalks, as well as the prized grain or sugar - to be fermented into fuel.

Advocates for this technology, including President Bush in his State of the Union address, have wrongly confused the sexy promise of this new-fangled approach to making ethanol with the practical realities of fuel markets. Schemes to produce cellulosic biomass, today, work only under special circumstances and nobody has delivered the fuel at the industrial scale that would be required for the technology to become commercially viable.

-Second, we should learn that, for now, the greatest force to loosen the world's oil markets lies with oil itself. We can use oil more efficiently, as would occur with a gasoline tax or wise fuel economy standards. But we can also find ways to produce more of the stuff - as Brazil did with Petrobras.

The problem for U.S. policy-makers is that the richest veins for new production lie mainly outside the United States and beyond our direct control.

Indeed, the Brazilian government made Petrobras more efficient by putting the firm partly beyond its control as well. When the government sold part of the company on international stock exchanges, it accepted Western accounting procedures and other strictures that have given Petrobras the autonomy and accountability to its shareholders that, in turn, helped make it an efficient company.

We have a stake in seeing other countries do the same - from Algeria to Mexico to Iran and even Russia. But we must remember that Brazil did this on its own, in response to internal pressures for reform, with little leverage from foreign governments.

-Third, we should learn from Brazil not to confuse the goal of greater self-sufficiency with the illusion of independence. Even as Brazil has become self-sufficient it has also, ironically, become more dependent on world markets. That's because the Brazilian government has wisely relaxed price controls so that the prices of fuels within the country are set to the world market. Thus Brazilians see real world prices when they fill up at the pump, and the decisions about which cars to buy and how much to drive reflect real costs and benefits of the fuel they consume. That is why, even as the country becomes self-sufficient, Brazilians are working ever harder to be more frugal with oil - because the price at the pump is high and rising.

Dependence on oil is a liability that must be managed. But it is not an addiction.

Efficiency, sober policies toward modest alternatives such as ethanol, and more production - all tools of the manager, not the addict - are required. Brazil helps show the way, but only if we learn the right lessons.

Does the conflict in Iraq amount to a civil war? In many ways, the public debate over this question is largely political. Calling Iraq a "civil war" implies yet another failure for the Bush administration and adds force to the question of whether U.S. troops still have a constructive role to play.

Politics aside, however, the definition of civil war is not arbitrary. For some -- and perhaps especially Americans -- the term brings to mind all-out historical conflicts along the lines of the U.S. or Spanish civil wars. According to this notion, there will not be civil war in Iraq until we see mass mobilization of sectarian communities behind more or less conventional armies.

But a more standard definition is common today:

1) Civil war refers to a violent conflict between organized groups within a country that are fighting over control of the government, one side's separatist goals, or some divisive government policy.

By this measure, the war in Iraq has been a civil war not simply since the escalation of internecine killings following the bombing of a Shiite shrine in Samarra in February, but at least since the United States handed over formal control to an interim Iraqi government in June 2004.

Here's why: Although the insurgents target the U.S. military, they are also fighting the Shiite-dominated Iraqi government and killing large numbers of Iraqis. There is little reason to believe that if the United States were suddenly to withdraw its forces, they would not continue their battle to control or shape the government.

Political scientists who study civil war have proposed various refinements to this rough definition to deal with borderline cases. One issue concerns how much killing has to occur -- and at what rate.

2) For a conflict to qualify as a civil war, most academics use the threshold of 1,000 dead, which leads to the inclusion of a good number of low-intensity rural insurgencies.

Current estimates suggest that more than 25,000 Iraqis have been killed in fighting since the U.S.-led invasion in March 2003 -- a level and rate of killing that is comparable to numerous other conflicts that are commonly described as civil wars, such as those in Lebanon (1975-1990) and Sri Lanka (beginning in 1983).

The organization -- or rather, disorganization -- of the warring communities in Iraq means that a large-scale conventional conflict along the lines of the U.S. Civil War is unlikely to develop. More probable is a gradual escalation of the current "dirty war" between neighborhood militias that have loose ties to national political factions and are fighting almost as much within sectarian lines as across them.

This is roughly what happened in Lebanon and at a lower level in Turkish cities in the late 1970s. Ethnic cleansing will occur not as a systematic, centrally directed campaign (as in Bosnia), but as a result of people moving to escape danger.

And there's another twist to the terminology:

3) If the conflict in Iraq becomes purely a matter of violence between Sunni and Shiite communities driven by revenge and hatred rather than by political goals, many political scientists would say that it is something other than civil war.

Almost no one, for example, calls the Hindu-Muslim violence in India a civil war.

A civil war has to involve attempts to grab power at the center of government or in a given region, or to use violence to change some major government policy.

In Iraq's case, however, the vacuum of power at the center means that communal violence will inevitably be tied to struggles for political power and control.

A final complication concerns the nature of international involvement. Some argue, for example, that the war in Bosnia should be seen as an interstate war rather than a civil war, since the Bosnian Serb forces were armed and directed largely by Belgrade. Post-Mobutu violence in Congo is often termed a civil war, even though fighters have been closely tied to armies from neighboring states.

4) A conflict may be both a civil and an interstate war at the same time.

The Vietnam War, for instance, clearly comprised both a civil war in the South and an interstate war involving the North, the South and the United States.

Iraq may be moving in this direction. The United States and Britain are already openly involved, and such neighboring countries as Iran and Syria are more covertly involved. Not that it matters to the people dying there, but the next debate here may turn on whether what is already a civil war in Iraq should be viewed as an interstate war as well.
