ONE OF THE BIGGEST developments in Syria’s five-year civil war came with the surprise announcement from Munich, that the warring factions had agreed a temporary cease-fire and to coordinate the delivery of humanitarian aid to besieged areas. If the agreement can hold, it would be a remarkable turn in a conflict that has seemed to defy all efforts at a peaceful resolution.

The ultimate breakthrough may have come not at the table but on the battlefield. A Russian blitzkrieg on Aleppo broke the stalemate around the most important contested city in Syria, threatening to cut off millions of rebel supporters and eliminate the last major bastion of the opposition not dominated by jihadis.

Diplomats accused Russia of stringing the United States along with negotiations; Syrian opposition fighters spoke of betrayal; and an American intelligence official told Congress that Russia had “changed the calculus completely.”

The move on Aleppo outraged and stunned American policy makers, but it shouldn’t have. Russia was treading on familiar territory when it forced new facts on the ground while simultaneously engaging in peace talks.

On the contrary, any policy maker interested in predicting what might work long-term in Syria can turn to the rich body of scholarship on civil wars, almost perfectly suited to align expectations with reality. “History can tell us a lot about this kind of situation and this kind of conflict,” said Christopher Paul, a senior social scientist who studies modern insurgencies at the RAND Corporation. “There’s always a danger in getting caught up with what’s unique about a case while it’s going on rather than with the clarity of hindsight.”

One of Paul’s recent projects analyzed 71 conflicts fought between 1944 and 2010; he identified a series of seven steps that led to negotiated settlements — necessary preconditions for a diplomatic solution to a civil war. The odds he tabulated should humble expectations: Only 13 of the 71 insurgencies he studied were resolved by a political negotiation.

Since the end of the Cold War in 1991 an increasing share of conflicts were fought within states rather than between them, prompting social scientists to delve into the study of civil war with particular intensity. The Pentagon funded academic examinations of every civil war and insurgency of the last century. There was an unusual confluence of theoretical and practical interest, with scholarly studies of civil war designed to help policy makers deal with the ongoing conflicts of our times. Researchers probed thorny questions of identity, sectarianism, and ideological grievance that often bedevil social scientists but play a crucial role in civil wars.

The research tells us how long civil wars tend to last and what factors prolong or resolve them; what steps tend to lead to a negotiated settlement and what presages a resolution established on the battlefield.

When Russia raced to Aleppo, the real mystery is why anyone was surprised.

FRATRICIDAL CONFLICTS are most effectively won, not negotiated. Sadly, in practice, the most enduring way to resolve a civil war is often the one with the most horrific human costs. Most other outcomes, including peace accords reached under international pressure, tend to be unstable and marred by continuing flare-ups of violence. Until last week, Syria has offered a painful illustration of this cold fact.

Incredulous Syrian rebels in interviews and private conversations before the announced truce said bitterly that the Damascus regime and its Russian and Iranian patrons would only negotiate after they’d already won as much as they could and destroyed what’s left of the original uprising. US officials complained in public that Russia was tanking any prospect of a fair or humanitarian end to the war, although they were more sanguine in private. Two senior officials said that as much as they decried the Russian approach, they expected Moscow to push for the best outcome it could get. They didn’t expect Russia or Syrian President Bashar Assad to sign away territory or make political concessions until they had seen what a year or more of vigorous Russian military intervention would yield.

Years of study have confirmed what’s intuitively obvious: No one wants to negotiate seriously until they’ve given up hope of winning on the ground. With Russian support, the Assad regime seemed to believe it could reconquer most of its territory — so why seek a deal before it was ready?

The war appeared deadlocked on the ground because the two international coalitions appeared balanced, said Stathis Kalyvas, the Yale political scientist who helped pioneer contemporary study of civil wars. “The question to ask is. . . what are the costs they pay to keep fighting?”

Overall, civil wars last about 10 years. If all sides get used to a stalemate, a war can go on far longer. The greater the number of factions and international sponsors involved, the longer a civil war tends to last. Syria’s civil war is now in its fifth year.

Some experts compare Syria’s war to the grinding, decades-long conflicts in Congo and Afghanistan, which also involved more than two factions and deeply implicated foreign sponsors of proxy armies. Other scholars, like MIT’s Fotini Christia, argue that Bosnia is a better parallel, because like Syria it had a high level of education and development before collapsing into strife, and its domestic factions relied on nearby foreign backers.

Breakthroughs historically occur when both sides finally acknowledge that they can’t win — or when one side finds that it actually can.

PAST CONFLICTS SHOW that a stable equilibrium doesn’t usually come with a victory for the good guys (or better guys if all sides are unsavory), the establishment of justice, or any of the moral outcomes that the international community tends to promote.

About 70 percent of civil wars end with outright victory, roughly 40 percent of the time for the government and 30 percent of the time for rebels, according to several data sets. After the fall of the Soviet Union, negotiated settlements, while still the exception, became more common, because international coalitions were willing to sponsor negotiations and then enforce the settlements with peacekeepers.

Unless one side wins outright, fighting factions only see an incentive to negotiate when they run short of fighters and their international patrons lose patience.

Political settlements usually involve a division of power that reflects the territorial disposition of the war, said Barbara F. Walter, a political scientist at the University of California, San Diego. In Syria’s case that’s a long shot long-term — a settlement based on the current front lines would cede major areas to the Islamic State and Nusra Front and would require the Assad regime to share power with Sunni rebel groups, a prospect that all sides still categorically reject. Effective settlements also require international guarantors willing to enforce an agreement.

Three years ago, Walter judged the likelihood of a negotiated settlement in Syria as “close to zero despite the efforts of the Obama administration to convince us otherwise.”

Today, she says, “what’s changed is that the incentives to stop fighting and start seriously negotiating are becoming more prominent.”

Outside sponsors were tiring of spending money on the conflict, Walter said, while edging closer to the view that a compromise might benefit everyone.

Walter believes it’s possible for Syria’s warring sides to eventually agree on a power-sharing formula. But she said finding peacekeepers, the third precondition of successful peace accords, would be more elusive. “How do you enforce an agreement over time?” Walter asked. Iraq, for example, failed under Prime Minister Nuri al-Maliki because no neutral power was able to enforce the power-sharing agreement between Shia, Sunni, and Kurds.

For scholars steeped in dozens of civil war case studies, and who aren’t advocating for any particular policy course, the evidence in Syria points to a slow, messy resolution. “There is probably no long-run military solution to this war in the sense it is extremely hard to see how you could get back to Assad ruling the country as he did in, say, 2010 or 2005,” said James Fearon, a Stanford political scientist. “I can imagine a partial victory that implies a rough and messy de facto partition of the country, that would drag on with lots of skirmishing.”

Civil war research offers a sobering warning to those in Syria and the international community who seek a major shift in Syria. Similar conflicts in Afghanistan and Congo stretched on for decades. Neighboring Iraq has hosted an ongoing civil war-cum-insurgency for nearly 13 years, featuring many of the same players involved in the Syrian war.

“A major concern about the current policy debate is there is so much pressure to resolve this conflict quickly, and history suggests that it will take time,” said RAND’s Paul. “Push hard and aggressively, by all means, to encourage settlement, but don’t be surprised if it’s hard and things break down repeatedly. It takes time, and requires strategic patience.”

Social science isn’t always the answer, but when it comes to civil wars and insurgencies, it can be a helpful corrective. The fighting factions in a civil war and the states that back them are often unable, or unwilling, to make clear-headed assessments of their own prospects. They have little incentive to be realistic about their chances of victory or concerned about the humanitarian costs of their actions.

If the tentative cease-fire announced at Munich is implemented, the scholarship warns us to be patient and temper our hopes; it often requires several rounds before there’s enough trust among warring parties for the truce to last, and implementation can prove as tricky as the initial negotiation.

Political science doesn’t tell us everything, said Marc Lynch, a political scientist at George Washington University, but it outlines what’s possible and what’s impossible. In the case of Syria, long studies of civil wars that have become “internationalized,” with multiple outside powers reinforcing their proxies and blocking victory by their opponents, make clear that quick and easy victories are impossible. A decisive Russian intervention could have changed the war but couldn’t end it on its own; in a similar manner, Lynch says, a full-on US intervention wouldn’t have decisively resolved Syria’s civil war either.

Iran’s Vietnam?

ARSAL, Lebanon — For more than a year, leaders in Lebanon have anxiously eyed the murderous civil war in Syria, wondering whether it would leap across the border and engulf the small, fractious country. And yet, it is Lebanon that now has jumped decisively into the fray, with Hezbollah’s help apparently crucial to the Syrian regime’s strategy and survival.

Uniformed Hezbollah fighters openly patrol the northern reaches of Lebanon’s Beqaa Valley, fighting on either side of the increasingly porous border with Syria. Rocket and mortar teams target Free Syrian Army (FSA) fighters a few miles away, and Lebanese Hezbollah infantry fighters crisscross the “Shiite villages” surrounding the city of Qusayr just across the border in Syria, which now forms one of the pivot points of the conflict.

The fighting around Qusayr has brought into the open the parlor game over whether Iran and Hezbollah are active combatants in Syria’s war. In an April 30 speech, Hezbollah chief Hassan Nasrallah hinted at greater involvement from the Lebanese paramilitary group in Syria, warning that the regime had “real friends” who would prevent Syria from “fall[ing] into the hands” of the United States and Israel.

The thunder of artillery fire in the mountains flanking the Beqaa Valley, like the spate of no-longer-hidden Hezbollah funerals, make clear that Hezbollah and its Iranian sponsors have crossed a Rubicon. They are now fully vested factions in the Syrian civil war, and they’re committed to an open and escalating fight.

Not 20 miles from Hezbollah’s position as the crow flies, FSA fighters flee across the border to the Sunni village of Arsal, nestled north in the Beqaa Valley in the mountains separating Lebanon and Syria. They make no distinction between the Syrian army, Hezbollah, and Iran — because, they say, they get shot at by all three.

“We could have common interests with Hezbollah, but they’re attacking us. Now there are grudges, which we will have to settle after the war,” said Shehadeh Ahmed Sheikh, 24, a self-described mortar man in the FSA. He was sitting cross-legged on the floor of an unfinished home in Arsal. Sheikh had brought with him 16 members of his extended family after their house in Qusayr had been destroyed earlier that week; as we talked, they squatted around him in the dwelling, which they had been assigned to by Arsal’s mayor.

Like many Sunnis in the area, he referred to Hezbollah, whose name means “the Party of God” in Arabic, as Hezb al-Shaitan — “the Party of Satan.”

By supporting Syrian President Bashar al-Assad to the hilt, Hezbollah and Iran are risking their hard-won reputation as stewards of an anti-Israel and anti-U.S. alliance that transcends sect and nationality. Syrian combatants increasingly understand the war in sectarian terms: On one side there is the Sunni majority; on the other side, other sects and a small group of Sunnis that have made common cause with the Alawite regime.

Western diplomats estimate that a few thousand Hezbollah fighters are involved in the Syrian fighting. Close observers of the group, which carefully guards its operational structure, say that they mistrust any precise numbers. But if Hezbollah has sent hundreds, or even a few thousand, of its best-trained fighters to Syria, that deployment certainly represents a significant percentage of its fighting force. During its 2006 war with Israel, the highest estimate of Hezbollah fighters killed was about 700, with the group’s own official death toll closer to 300.

Sunnis are increasingly framing the conflict as a sectarian jihad. The influential Lebanese Salafi cleric Ahmad Al-Assir has set up his own militia, suggesting his fighters would be just as willing to confront Hezbollah in Lebanon as they already are to travel to Syria to fight alongside the rebels there. Supporters of the regime and Hezbollah point out that the rebellion tolerates Sunni fundamentalist extremists whereas Assad and Hezbollah rely on a time-tested alliance of minorities, including Alawites, Christians, Druze, and Shiite Muslims. The propaganda of both sides has sharpened a narrative of the Syrian conflict as a struggle between Sunni extremists and old-style authoritarians, who at least protect the minorities they exploit. Deadly identity politics have taken root, and people on both sides of the conflict see it more and more as a matter of survival. Sheikh, the young Sunni fighter, planned to return to battle as soon as he settled his family: “We cannot go back to the way things were before.”

On the eve of the uprisings just three short years ago, many Arab analysts observed half-jokingly that the most influential state in the Arab world wasn’t Arab at all — it was Iran, awash in oil revenues and ready to lavish cash on a region in the throes of an increasingly hot Sunni-Shiite cold war. Sunni monarchs and dictators fretted about a “Shiite Crescent” linking Iran, Iraq, Syria, and Hezbollah. Tehran, for its part, strutted triumphantly across the Arab stage, bragging about an unstoppable “Axis of Resistance” oiled with ideological fervor and the supreme leader’s bank account.

What a difference a few uprisings can make. Today, Iran’s involvement in Syria has all the makings of a quagmire, and certainly represents the Islamic Republic’s biggest strategic setback in the region since its war with Iraqi dictator Saddam Hussein ended in 1988. Syria’s conflict has begun to attract so much attention and resources that it threatens to end the era when Iran could nimbly outmaneuver the slow-moving American behemoth in the Middle East.

Iran — already reeling from sanctions — is spending hundreds of millions of dollars propping up Bashar al-Assad’s regime. In the murky arena of sub rosa foreign intervention, it’s impossible to keep a detailed count of the dollars, guns, and operatives the Islamic Republic has dispatched to Syria. Westerners and Arab officials who have met in recent months with Syrian government ministers say that Iranian advisers are retooling key ministries to provide copious military training, including to the newly established citizen militias in regime-controlled areas of Syria. “We back Syria,” Iranian General Ahmad Reza Pourdastan reiterated on May 5. “If there is need for training we will provide them with the training.”

In private meetings, Iranian diplomats in the region project insouciance, suggesting that the Islamic Republic can indefinitely sustain its military and financial aid to the Assad regime. To be sure, its burden today is probably bearable. But as sanctions squeeze Iran and it comes under increasing pressure over its nuclear program, the Islamic Revolutionary Guard Corps (IRGC) might find the investment harder to sustain. The conflict shows no signs of ending, and as foreign aid to the rebels escalates, Iran will have to pour in more and more resources simply to maintain a stalemate. If this is Iran’s Vietnam, we’re only beginning year three.

The cost of Tehran’s support of Assad can’t entirely be measured in dollars. Iran has had to sacrifice most of its other Arab allies on the Syrian altar. As the violence worsened, Hamas gave up its home in Damascus and its warm relationship with Tehran. Egypt’s Muslim Brotherhood-dominated government has also adopted a scolding tone toward Iran on Syria. On Egyptian President Mohamed Morsy’s first visit to Tehran, he took the opportunity to blast the “oppressive regime” in Damascus, saying it was an “ethical duty” to support the opposition.

Gone are the days when Iran held the mantle of popular resistance. Popular Arab movements, including Syria’s own rebels, now have the momentum and air of authenticity. Iran’s mullahs finally look to the Arab near-abroad as they long have appeared at home — repressive, authoritarian, and fierce defenders of the status quo.

Finally, and perhaps most importantly, Iran’s commitment to Assad has put the crown jewel of its assets in the Arab world, Hezbollah, in danger. Just a few years ago, a survey found that Nasrallah was the most popular leader in the Arab world. Along with other members of the “resistance axis,” Hezbollah mocked the rest of the Arab world’s political movements as toadies and collaborators, happy to submit to American-Israeli hegemony. Today, however, it has sacrificed this popular support and enraged Sunnis across the Arab world by siding with a merciless dictator.

Hezbollah used to try to cultivate allies from all sects, so that it wouldn’t seem to be pursuing a purely Shiite agenda, but it now appears in the eyes of the Arab world to have cast its lot — hook, line, and sinker — with a brutal minority regime in Syria over a popular, largely Islamist movement. A Pew survey last year found that the group’s popularity was declining in predominantly Sunni countries such as Egypt and Jordan, while Lebanese Sunnis and Christians also increasingly soured on the party.

In the border town of Hermel, usually secretive Hezbollah fighters have openly mobilized. They fight on both sides of the border, protecting a ring of Shiite villages in Syria that connect Damascus to the Alawite heartland. An untold number of Hezbollah fighters have been killed in Syria — so many that the movement has stopped keeping the funerals secret and has even released videos of some of the martyrs. “We bury our martyrs in the open,” Nasrallah said in his recent speech. “We are not ashamed of them.”

Hezbollah positions in Hermel were shelled on May 12, and the Sunni jihadist Nusra Front reportedly claimed responsibility. In their rhetoric, Lebanese politicians have sought to downplay the sectarian nature of the fight in Syria, and there are plenty of individuals who say they have chosen sides out of interest or ideology, rather than sect. Yet to most of its participants, the conflict has taken on an undeniably sectarian hue: an almost entirely Sunni rebellion, against a regime supported by the majority of Syria’s other sects.

“There’s no difference between Hezbollah, the army, and the Syrian regime,” scoffed Mustafa Ezzedine, a driver in Arsal who was recently dragged into the conflict as a literal hostage, kidnapped because he was a Sunni Muslim by a Shiite clan that wanted one of its own kidnapped members released. It doesn’t matter that among his guests at a recent, lazy hashish-fueled afternoon tea was a member of that same rival clan: sectarian politics have little regard for personal views. For residents of the Beqaa Valley, the war in Syria has already drifted across the border, and they fear it could get worse quickly.

The regional stakes are high as well. On at least one occasion, the Syrian conflict has cost an Iranian military commander his life. In mid-February, a shadowy IRGC officer responsible for overseeing Iranian reconstruction projects in Lebanon who went by the names Hessam Khoshnevis and Hassan Shateri was killed on the road from Damascus to Beirut. Iran put out the story that Israel assassinated their man, but Western and Arab officials told me they had seen reliable intelligence reports that it was a Syrian rebel ambush.

A who’s who of Lebanese politicians paid condolences at the Iranian embassy, and Hezbollah’s number two, Naim Qassem, delivered a long tribute to the fallen IRGC offer at a memorial service in an underground theater in Beirut’s Hezbollah-controlled southern suburbs. It was the latest sign that Hezbollah is willing to risk everything in supporting the Syrian dictator — and that Iran just may ask its Lebanese ally to fight to the end, or go down with the ship.

“We would be nothing without Iran!” Qassem thundered in his tribute. “Others hide the foreign funds they receive. We proudly open our hands to Iran’s gifts. What the resistance needs, they provide.”

What really drives civil wars?

WHAT IS a civil war, really?

At one level the answer is obvious: an internal fight for control of a nation. But in the bloody conflicts that split modern states, our policy makers often understand something deeper to be at work. The vengeful slaughter that has ripped apart Bosnia, Rwanda, Syria, and Yemen is most often seen as the armed eruption of ancient and complex hatreds. Afghanistan is embroiled in a nearly impenetrable melee between Pashtuns and smaller ethnic groups, according to this thinking; Iraq is split by a long-suppressed Sunni-Shia feud. The coalitions fighting these wars are seen as motivated by the deepest sort of identity politics, ideologies concerned with group survival and the essence of who we are.

This view has long shaped America’s engagement with countries enmeshed in civil war. It is also wrong, argues Fotini Christia, an up-and-coming political scientist at MIT.

In a new book, “Alliance Formation in Civil Wars,” Christia marshals in-depth studies of the recent wars in Afghanistan, Iraq, and Bosnia, along with empirical data from 53 civil conflicts, to show that in one civil war after another, the factions behave less like enraged siblings and more like clinically rational actors, switching sides and making deals in pursuit of power. They might use compelling stories about religion or ethnicity to justify their decisions, but their real motives aren’t all that different from armies squaring off in any other kind of conflict.

“The idea that today’s enemy can be the next day’s friend was very compelling to me,” Christia said in an interview. “We should not be surprised to see groups switching sides, based on how the balance of power on the ground evolves.”

How we understand civil wars matters. Most civil wars drag on until they’re resolved by a foreign power, which in this era almost always includes the United States. If she’s right, if we’re mistaken about what motivates the groups fighting in these internecine free-for-alls, we’re likely to misjudge our inevitable interventions—waiting too long, or guessing wrong about what to do.

CIVIL WARS ALWAYS have loomed large in the collective consciousness. Americans still debate theirs so vociferously that a blockbuster film about Abraham Lincoln feels topical 150 years after his death. Eastern Europe saw several years of ferocious killing in the round of civil wars that followed World War II.

Such wars have been understood as fights over differences that can’t be resolved any other way: fundamental questions of ideology, identity, creed. A disputed border can be redrawn; not so an ethnic grudge. In the last two decades, identity has become the preferred explanation for persistent conflicts around the world, from Chechnya to Armenia and Azerbaijan to cleavages between Muslims and Christians in Nigeria.

This thinking allows for a simple understanding, and conveniently limits the prospect for a solution. Any identity-based cleavage—Jew vs. Muslim, Bosnian vs. Serb, Catholic vs. Orthodox—is so profoundly personal as to be immutable. The conventional wisdom is best exemplified by a seminal 1996 paper by political scientist Chaim Kaufmann, “Possible and Impossible Solutions to Ethnic Civil Wars,” which argues that bitterly opposed populations will only stop fighting when separated from each other, preferably by a major natural barrier like a river or mountain range.

During the 1990s, this sort of ethnic determinism drove American policy toward Bosnia and Rwanda. It was popularized by Robert Kaplan’s book “Balkan Ghosts,” which was read in the Clinton White House and presented the wars in the former Yugoslavia as just the latest chapter in an insoluble, four-century ethnic feud. Like Kaufmann, Kaplan suggested that the grievances in civil wars could only be managed, never reconciled.

After 9/11, policy makers in Washington continued to view civil wars through this prism, talking about tribes and sects and ethnic groups rather than minority rights, systems of government, and resource-sharing. That view was so dominant that President Bush’s team insisted on designing Iraq’s first post-Saddam governing council with seats designated by sect and ethnicity, against the advice of Iraqis and foreign experts. It became a self-fulfilling prophecy as Iraq’s ethnic civil war peaked in 2006; things settled down only after death squads had cleansed most of Iraq’s mixed neighborhoods, turning the country into a patchwork of ethnically homogenous enclaves. Similarly, this thinking has shaped US policy in Afghanistan, where the military even sent anthropologists to help its troops understand the local culture that was considered the driving factor in the conflict.

 

Christia grew in up in the northern Greek city of Salonica in the 1990s, with the Bosnian war raging just over the border. “It was in our neighborhood and we discussed it vividly every night over dinner,” she says. The question of ethnicity seized her imagination: Were different peoples doomed to conflict by incompatible identities? Or were the decision-makers in civil wars working on a different calculus from their emotional followers? As a graduate student at Harvard, Christia flew to Afghanistan and tried to turn a dispassionate political scientist’s eye to the question of why warlords behave the way they do.

Christia spent years studying these warlords, the factional leaders in a civil war that broke out in the late 1970s. As a graduate student and later as a professor, she returned to Afghanistan to interview some of the nastiest war criminals in the country. She concluded that culture and identity, while important for their adherents, did not seem to factor into the motives of the warlords themselves, and specifically not in their choices of wartime allies. Despite the powerful rhetoric about ethnic alliances forged in blood, warlords repeatedly flipped and switched sides. They used the same language—about tribe, religion, or ethnicity—whether they were fighting yesterday’s foe or joining him.

If ethnicity, religion, and other markers of identity didn’t matter to warlords, Christia asked, what did? It turns out the answer was simple: power. After studying the cases of Afghanistan, Bosnia, and Iraq in intricate detail, Christia built a database of 53 conflicts to test whether her theory applied more widely. She ran regression analyses and showed that it did: Warlords adjusted their loyalties opportunistically, always angling for the best slice of the future government. It’s not quite as simple as siding with the presumed winner, she says: It’s picking the weakest likely winner, and therefore the one most likely to share power with an ally.

In this model of warlord behavior, the many factions in a civil war are less like Cain and Abel and more like the mafia families in “The Godfather” trilogy. Loyalties follow business interests, and business interests change; meanwhile, the talk about family and blood keeps the foot soldiers motivated. In Bosnia, one Muslim warlord joined forces with the Serbs after the Serbs’ horrific massacre of Muslims at Srebenica, and justified his switch by saying that the central government in Sarajevo was run by fanatics while he represented the true, moderate Islam. In case after case of intractable civil wars—Afghanistan, Lebanon, Iraq, the former Yugoslavia—Christia found similar patterns of fluid alliances.

“The elites make the decision, and then sell it to the people who follow them with whatever narrative sticks,” Christia said. “We’re both Christians? Or we’re both minorities? Or we’re both anti-communist? Whatever sticks.”

***

CHRISTIA’S WORK has been received with great interest, though not all her academic colleagues agree with her conclusions. Critics say identity is more important in civil wars than she gives it credit for, and we ignore it at our peril. Roger Petersen, an expert on ethnic war and Eastern Europe who is a colleague of Christia’s at MIT and supervised her dissertation, argues that in some conflicts, identity—ethnic, religious, or ideological—is truly the most important factor. Leaders might make a pact with the devil to survive, but once a conflict heads to its conclusion, irreconcilable conflicts often end with a fight to the death. Communists and nationalists fought for total victory in Eastern Europe’s civil wars, with no regard to their fleeting coalitions of opportunity against foreign occupiers during World War II. More recently, Bosnia’s war only ended after the country had split into ethnically cleansed cantons.

Christia acknowledges that her theory needs further testing to see if it applies in every case. She is currently studying how identity politics play out at most local level in present-day Syria and Yemen.

If it holds up, though, Christia’s research has direct bearing on how we ought to view the conflict today in a nation like Syria. The teetering dictatorship is the stronghold of the minority Allawite sect in a Sunni-majority nation. And leader Bashar Assad has rallied his constituents on sectarian grounds, saying his regime offers the only protection for Syria’s minorities against an increasingly Sunni uprising. But Syria’s rebellion comprises dozens of armed factions, and Christia suggests that these militants, which run the gamut of ethnic and sectarian communities, will be swayed more by the prospect of power in a post-Assad Syria than by ethnic loyalty. That would mean the United States could win the loyalty of different fighting factions by ignoring who they are—Sunni, Kurd, secular, Armenian, Allawite—and by focusing instead on their willingness to side with America or international forces in exchange for guns, money, or promises of future political power.

For America, civil wars elsewhere in the world might seem like somebody else’s problem. But in reality we’re very likely to end up playing a role: Most civil wars don’t end without foreign intervention, and America is the lone global superpower, with huge sway at the United Nations. Christia suggests that Washington would do well to acknowledge early on that it will end up intervening in some form in any civil war that threatens a strategic interest. That doesn’t necessarily mean boots on the ground, but it means active funding of factions and shaping of the alliances that are doing the fighting. In a war like Syria’s, that means the United States has wasted precious time on the sidelines.

Despite her sustained look at the worst of human conflict, Christia says she considers herself an optimist: People spend most of their history peacefully coexisting with different groups, and only a tiny portion of the time fighting. And once civil wars do break out, the empirical evidence shows that hatreds aren’t eternal. “If identities mattered so much,” she says, “you wouldn’t see so much shifting around.”
