Syria’s Civil War: The Descent Into Horror

The civil uprising against the longtime rule of the Assads deteriorated into protracted civil war. Here’s a look at the elements that have deepened Syria’s tragedy.

Ten years since protesters in Syria first demonstrated against the four-decade rule of the Assad family, hundreds of thousands of Syrians have been killed and some twelve million people—more than half the country’s prewar population—have been displaced. The country has descended into an ever more complex civil war: jihadis promoting a Sunni theocracy have eclipsed opposition forces fighting for a democratic and pluralistic Syria, and regional powers have backed various local forces to advance their geopolitical interests on Syrian battlefields. The United States is at the forefront of a coalition conducting air strikes on the self-proclaimed Islamic State, though it abruptly pulled back some of its forces in 2019 ahead of an invasion of northern Syria by Turkey, a North Atlantic Treaty Organization (NATO) ally. The Turks have pushed Kurdish forces, the United States’ main local partner in the fight against the Islamic State, from border areas. Russia, too, has carried out air strikes in Syria, coming to the Assad regime’s defense, while Iranian forces and their Hezbollah allies have done the same on the ground.

 

Map of Syria

Syria likely faces years of instability. Hopes for regime change have largely died out, and peace talks have been fruitless. The government has regained control of most of the country, and Assad’s hold on power seems secure. But Turkish forces remain entrenched in the north, and pockets of northeastern Syria are either under the control of Kurdish forces or go ungoverned. Meanwhile, the Syrian people are suffering an economic crisis.

Assads’ Rule Breeds Discontent

Hafez al-Assad seized control from a Baathist military junta in 1970, centralizing power in the presidency. He came from the Alawi minority, a heterodox Shia sect that had long been persecuted in Syria and was elevated to privileged positions under the post–World War I French mandate.

In February 1982, Hafez al-Assad ordered the military to put down a Muslim Brotherhood uprising in the city of Hama with brute force. Syrian forces killed more than twenty-five thousand there. For the regime’s opponents, Hama would become a rallying cry in 2011. For the regime, it provided Hafez’s son and successor, Bashar, with a template for responding to dissent.

The Assads presided over a system that was not just autocratic but kleptocratic, doling out patronage to bind Syrians to the regime. As the 2011 uprising turned into civil war, many members of minority groups remained loyal to the regime, but so too did some Sunnis, fearing revenge if opposition forces were to take Damascus.

Economic Reforms Upend Syrian Society

Bashar al-Assad succeeded his father in 2000 pledging reforms. He promised to let markets take the place of the “Arab socialism” touted by the Baathist state, upending old patronage networks. He broke up and privatized state monopolies, but the benefits were concentrated among those well-connected with the regime, while the end of subsidies and price ceilings harmed rural peasants and urban laborers. A record-setting drought from 2006 to 2010 exacerbated socioeconomic problems. Mismanaged farmland was rendered fallow and farmers migrated to cities in ever-larger numbers, causing the unemployment rate to surge.

Arab Uprisings Echo Across Repressed Region

The Arab Spring began in December 2010 with the self-immolation of a Tunisian fruit vendor decrying corruption. His act prompted protests in Tunisia, and then across the Middle East and North Africa, which forced longtime strongmen in Tunisia, Egypt, and Yemen to step down. Inspired by these previously unthinkable events, fifteen boys in the southwestern city of Deraa, Syria, spray-painted on a school wall: “The people want the fall of the regime.” They were arrested and tortured. Demonstrators who rallied behind them clashed with police, and protests spread. Many protesters were calling for something more modest than regime change: the release of political prisoners, an end to the half-century-old state of emergency, greater freedoms, and an end to corruption. Unlike Tunisia’s Zine al-Abidine Ben Ali and Egypt’s Hosni Mubarak, Assad responded to protesters immediately, offering just token reforms while directing security services to put down the protests with force.

From Protest Movement to Civil War

Anti-regime protests soon spread from Deraa to major cities such as Damascus, Hama, and Homs. Events in Deraa offered a preview of what was to come elsewhere: The Syrian army fired on unarmed protesters and carried out mass arrests, both targeting dissidents and indiscriminately sweeping up men and boys, human rights monitors reported. Torture and extrajudicial executions were frequently reported at detention centers. Then, in late April 2011, the Syrian army brought in tanks, laying siege to Deraa. The civilian death toll mounted and residents were cut off from food, water, medicine, telephones, and electricity for eleven days. Amid international condemnation, the regime offered some concessions, but it also repeated the Deraa response in other places where there were protests, at far greater length and cost, leading some regime opponents to take up arms. Local coordinating committees sprang up in villages and urban neighborhoods. Originally established to organize resistance to the regime, many of these committees would take on the roles of public administration and service provision.

A Disorganized Opposition Splinters

In July 2011, defectors from Assad’s army announced the formation of the Free Syrian Army (FSA), and soon after they began to receive shelter in Turkey. Yet the FSA, outgunned by the regime, struggled to bring its loose coalition under centralized command and control. FSA militias often didn’t coordinate their operations and sometimes had competing interests, reflecting their varied regional backers. With resources scarce, they preyed at times on the very populations they were charged with protecting. The FSA’s civilian counterpart was also established in summer 2011, in Istanbul. The Syrian National Coalition (SNC) claimed to be the government-in-exile of Syria, and the United States, Turkey, and Gulf Cooperation Council countries, among others, soon recognized it as “the legitimate representative of the Syrian people.” But the SNC and its successor, the National Coalition, were unable to deliver significant diplomatic or material support to the opposition, and many of the regime’s opponents within Syria accorded it little legitimacy. Rival coalitions began to proliferate, and FSA fighters drifted to Islamist brigades that, with funding and arms from Gulf donors, scored greater battlefield successes against the regime.

Al-Qaeda and Islamic State Emerge

The regime’s torture and killing was exploited by al-Qaeda militants eager to capitalize on Syria’s chaos. In January 2012, a group called Jabhat al-Nusra announced itself as al-Qaeda’s Syrian franchise, and the following month al-Qaeda chief Ayman al-Zawahiri called for Sunnis from around the region to join a jihad against the regime. Jabhat al-Nusra gained Syrian and foreign recruits as it scored greater battlefield successes than rival opposition groups.

In April 2013, a group formed from the remnants of al-Qaeda in Iraq that called itself the Islamic State of Iraq emerged and exceeded even Jabhat al-Nusra in its brutality. In several months, its forces established control over territory spanning eastern Syria and western Iraq. The ascendance of the Islamic State and other extremists groups fed an increasingly sectarian conflict, and civilians living in the fiefs of the Islamic State—like those living under the control of the FSA and pro-regime militias—suffered abuse.

The rise of extremist groups in Syria was, in part, the regime’s own doing, as Assad wanted to present to the world a stark choice between his secular rule and a jihadi alternative. In mid-2011, the regime released hundreds of Islamist militants from prisons to discredit the rebellion. They would form extremist groups such as Ahrar al-Sham, which espoused a sectarian agenda.

Civilians as Targets

Both Assad’s forces and rebel groups have regularly targeted civilians in areas outside of their control. The deaths of some 1,400 civilians from chemical weapons deployed by the Assad regime in the summer of 2013 mobilized world powers to dismantle the regime’s chemical arsenal. However, in the years since, the Syrian government has employed devastating conventional arms that have also caused massive civilian casualties.

The regime has made regular use of sieges and aerial bombardment. These collective-punishment tactics serve dual purposes, analysts say: they raise the costs of resistance to civilians so that they will pressure rebels to acquiesce, and they prevent local committees from offering a viable alternative to the regime’s governance. In 2018, the UN humanitarian agency said more than one million people lived in areas that were besieged or otherwise beyond the reach of aid.

Despite a UN Security Council resolution in 2014 aimed at securing humanitarian aid routes, aid became politicized as Assad would grant UN convoys permission to distribute food and medicine in government-held areas while denying them access to rebel-held areas, and rights advocates charged the regime with targeting medical facilities and personnel [PDF]. In 2020, Syria’s ally Russia used its veto at the Security Council to allow UN aid deliveries to the rebel-held north through only one border crossing, down from four the previous year.

From Domestic Rebellion to Internationalized Civil War

The deepening of Syria’s civil war made both pro- and anti-regime forces dependent on external sponsors. As major powers have deepened their involvement, Syria has become a battlefield on which the region’s geopolitical rivalries have been fought.

As mounting casualties and desertions weakened Assad’s army, the regime came to rely increasingly on Iran and Russia. Iran, a longtime ally interested in protecting a vital land route to its Lebanese proxy, Hezbollah, has invested billions in propping up the regime. Iran’s Revolutionary Guard Corps advises Assad’s army and has sustained thousands of casualties. The Iranian volunteer Basij paramilitary force and the foreign Shia militias it has rallied have suffered even more casualties.

Russia has provided Assad with critical diplomatic support. Moscow cited the 2011 NATO-led intervention in Libya and the ensuing chaos there as justification for vetoing measures in the UN Security Council that would have punished the Syrian regime. Russia then entered the conflict directly in September 2015 with the deployment of its air force. Though Moscow claimed its air strikes would primarily target the Islamic State and al-Qaeda, analysts said it more often targeted other rebel groups, some backed by the United States and many intermingled with al-Qaeda’s affiliate near the front lines with the regime. This helped Assad strengthen his control of population centers along the country’s western spine.

Opposition forces, too, have had foreign backers. For several years, the United States covertly trained and armed rebel fighters. France and the United Kingdom have provided logistical and military support. Additionally, the short-lived rapprochement by Qatar and Saudi Arabia in 2015 enabled the formation of the Army of Conquest, which comprised an array of opposition and extremist groups but effectively disbanded after several years.

The Kurdish Bid for Autonomy

Kurds have fought to consolidate a de facto autonomous territory in northern Syria, which has made them alternately friends and foes of Arab opposition groups. The Islamic State’s siege in 2014 of Kobani, a strategically located Kurdish town near the Turkish border, was a turning point. The defense of the town by the Kurdish People’s Protection Units (YPG) highlighted the militant group’s effectiveness against the Islamic State. U.S. forces aided in ousting Islamic State fighters from Kobani and continue to provide arms and air support to the YPG-led Syrian Democratic Forces (SDF).

Over time, the YPG’s priority turned to consolidating autonomous Kurdish cantons in the country’s north, a region the Kurds refer to as Rojava (Western Kurdistan). YPG fighters, interested in protecting fellow Kurds, have been accused of ethnic cleansing in mixed Arab-Kurd areas. The YPG is tied to the Turkey-based Kurdistan Workers’ Party (PKK), which Ankara and Washington have designated a terrorist organization. In August 2016, Turkey deployed its military along the Syrian border to both roll back Islamic State forces and, in tandem with Syrian Arab and Turkmen fighters, block the Kurds from linking up their two cantons in a contiguous territory. The United States had faced the dilemma of trying not to alienate either the YPG or Turkey, a NATO ally that was also a vital partner in the war against the Islamic State. But Washington eventually chose Ankara, agreeing in October 2019 to remove its troops in Syria near the Turkish border so Turkey could launch a military offensive against the Kurds.

The Diplomatic Thicket

UN-backed attempts to mediate a conflict-ending political transition in Syria have been stymied by differences among veto-wielding permanent members of the UN Security Council and other powers. Qatar, Saudi Arabia, and Turkey aligned with the United States against the Assad regime, while Iran joined Russia in backing it. Russia and China have cast multiple vetoes on Syria-related Security Council resolutions, and the threat of veto has deterred or watered down humanitarian and human rights measures, reinforcing a view of the council as toothless. A June 2012 multilateral document known as the Geneva Communiqué became the basis for one set of negotiations. It calls for “a Syrian-led political process,” beginning with the establishment of a transitional governing body “formed on the basis of mutual consent.” But multiple rounds of peace talks to implement these principles have yielded little. A core issue is Assad himself: he has no interest in negotiating his own political demise and retains Russia’s and Iran’s backing, while the possibility of Assad staying on in a transition is anathema to the opposition.

Because prospects for a negotiated settlement are dim, the United States has focused on counterterrorism activities while calling for de-escalation. Meanwhile, Iran, Russia, and Turkey have taken the diplomatic initiative, sidelining the UN-led process and excluding the United States. But though they have agreed in principle on maintaining Syria’s territorial integrity and achieving a “lasting cease-fire,” their agreements to work through their respective local allies to de-escalate the conflict have come to naught.

Refugee Crisis Rattles EU

More than half of Syria’s prewar population of twenty-two million has been displaced by the violence, with more than six million displaced internally and another six million fleeing abroad. Neighboring countries have borne the heaviest burden: Lebanon, a country of only 4.5 million people, is hosting more than one million Syrians, and Jordan, with more than half a million Syrians, for years blocked would-be refugees from crossing the border. Turkey is host to more than three million Syrians, straining government resources. With limited work and educational opportunities, and little hope that they will soon be able to return safely home, more than one million refugees have journeyed to Europe, contributing to what the United Nations has called the largest migrant and refugee crisis since World War II.

Disputes over how to settle refugees across the European Union (EU) have posed a severe challenge to the bloc, threatening to bring an end to the Schengen system of open borders on the continent and contributing to the rise of anti-immigrant, far-right parties. The EU struck an agreement with Turkey to block refugees’ northward migration in 2016, but since then, Turkish President Recep Tayyip Erdogan has periodically threatened to permit hundreds of thousands of migrants to cross into Europe.

East Aleppo Falls to Pro-Regime Forces

The regime captured the last rebel-held enclave of eastern Aleppo in December 2016 after a prolonged siege and bombardment. The city, Syria’s economic powerhouse, had been contested since 2012, and its capture marked a stark reversal of fortune for the opposition; in 2013, rebels had nearly encircled the regime-controlled western part of the city. But the campaign also demonstrated how dependent Assad has become on his foreign backers—both the Russian air force and Shiite militias—as his own forces have weakened.

Scores of civilians were massacred in the battle’s last days in what a UN spokesperson called “a complete meltdown of humanity.” With their defeat in Aleppo, rebels were isolated to northern Idlib province, parts of the south, and small enclaves around Damascus and Homs.

Islamic State Decimated, Stoking New Conflicts

The U.S.-led coalition, along with the Kurdish-led SDF, has rolled back the Islamic State to a handful of small pockets. The Pentagon says the group’s territory has been reduced to about 2 percent of what it once held in an area between Iraq and Syria. By some estimates, the Islamic State in Syria has shrunk to a few thousand militants, but with that came high civilian casualties, the destruction of population centers, and mass displacement. More than sixty thousand refugees live in the SDF-managed al-Hol camp in northeastern Syria. Many were displaced by the insurgency, while others are Islamic State loyalists and their families; eighty percent of them are women and children. Although the camp is overpopulated, and conflict between the Islamic State’s victims and its supporters are common, many refugees have nowhere else to go. Thousands of them are foreigners who joined the terrorist group and whose countries will not allow them to return.

As the threat from the Islamic State diminished, simmering rivalries took on new intensity. In early 2018, Turkish forces occupied Afrin, a predominantly Kurdish enclave in northwestern Syria. Amid the Turkish escalation, SDF fighters were diverted from the fight against the Islamic State, redeploying to Afrin.

Chaos in Northern Syria

The civil war entered a new stage in October 2019 after U.S. President Donald J. Trump removed the roughly one thousand U.S. troops supporting Kurdish fighters on the Syria-Turkey border. The surprise move cleared the way for Turkey’s Erdogan to launch a military operation there. Aiming to push Kurdish forces back to establish a twenty-mile-deep buffer zone for returned refugees, Turkish troops and their Syrian rebel allies seized towns and villages, causing hundreds of thousands of people to flee. The SDF turned to the Syrian government for help, allowing regime soldiers to reenter areas that had been held by the Kurds for years. Russian troops also entered the region to support the Syrian government.

The Turkish incursion drew international condemnation. The United States sanctioned top Turkish officials and threatened to raise tariffs on steel, but a brief cease-fire led Trump to lift the sanctions after one week, and the tariffs ultimately remained unchanged. Erdogan says his troops will not back down until they establish a twenty-mile-deep buffer zone in Syria for returned refugees.

Unprecedented Displacement, Islamic State Returns

With the assistance of their foreign backers, Assad’s forces besieged and bombarded the rebels’ final redoubts in Syria’s northwest in late 2019, imperiling hundreds of thousands of civilians. By December, the regime and its allies advanced into Idlib, where Russia-backed forces launched a devastating air campaign and clashes resumed between the regime and Turkish forces seeking to protect their opposition posts in the area. A cease-fire agreement signed by Ankara and Moscow in January quickly collapsed as regime forces captured cities along the strategically significant M5 highway, which connects Damascus and Aleppo. Hostilities between the regime and the Turks intensified in February 2020, when Syrian government forces killed Turkish troops in direct combat for the first time, spurring Turkey to retaliate with strikes against dozens of regime targets. The fighting endangered Idlib’s population, which ballooned to three million as government authorities offered rebel fighters and civilians the choice of surrendering—risking conscription or arrest—or being bused north to the province. The heightened violence resulted in the war’s largest mass displacement to date, with some nine hundred thousand people forced from their homes A March 2020 cease-fire agreement between Moscow and Ankara has largely quelled the fighting, despite violations on both sides.

Meanwhile, the Islamic State increased its attacks in Syria’s northeast soon after the U.S. killing of the group’s leader, Abu Bakr al-Baghdadi, in October 2019. Despite the troop drawdown announced in October, some five hundred American soldiers remain in eastern Syria to prevent the Islamic State from accessing the region’s oil fields.

Ten Years On

A decade after the uprising that sparked the war, Syria is still mired in low-level conflict, political instability, and economic turmoil. The 2020 cease-fire has stemmed violence in the Turkey-controlled northwest, while the regime controls most of the rest of the country with help from Russia and Iran. At the same time, Israel has increasingly bombed targets in Syria said to belong to Iran-linked militias, including Hezbollah. A U.S. air strike targeted an Iraq-based militia in Syria just weeks after the inauguration of President Joe Biden in 2021.

Though the violence has waned, civilians are now suffering an economic crisis. More than 80 percent of the population lives in poverty. Syrians have been the main victims of international sanctions, including the U.S. Caesar Act, which is meant to pressure the regime to reform. Though having little apparent effect on Assad, the sanctions have discouraged states such as the United Arab Emirates from normalizing relations with Syria.

Diplomacy also has yet to sway Assad’s government. A UN-facilitated constitution-drafting committee that was formed in 2019 brought together 150 representatives of civil society, the regime, and the opposition. But the 2020 coronavirus pandemic stalled talks for months, and the committee quickly reached an impasse after restarting in January 2021. Some observers suspect that Assad seeks to delay progress so he can hold a presidential election scheduled for spring 2021 without UN supervision. A 2015 UN Security Council resolution says UN-supervised voting should follow the creation of a new constitution.

While the UN-led talks founder, the rival process led by Iran, Russia, and Turkey is no closer to resolving Syria’s political crisis. Further complicating the diplomatic field, Qatar, Russia, and Turkey began another track of negotiations on Syria’s peace process in March 2021.
