BEIRUT — Three years ago, a black-clad cleric named Abu Bakr al-Baghdadi ascended a mosque pulpit in the Iraqi city of Mosul and addressed the world as leader of a new terrorist state.
The announcement of the caliphate was a high point for the extremist fighters of the Islamic State group (ISIS). Their exhibitionist violence and apocalyptic ideology helped them seize vast stretches of territory in Syria and Iraq, attract legions of foreign fighters and create an administration with bureaucrats, courts and oil wells.
In Syria, U.S.-backed militias have surrounded Raqqa, the group’s capital, and breached its historic walls. Across the border, Iraqi forces have seized the remains of the Mosul mosque where al-Baghdadi appeared and besieged the remaining jihadis in a shrinking number of city blocks.
But the loss of its two largest cities will not spell a final defeat for ISIS — also known as ISIL and Daesh — according to analysts and U.S. and Middle Eastern officials. The group has already shifted back to its roots as an insurgent force, but one that now has an international reach and an ideology that continues to motivate attackers around the world.
“These are obviously major blows to ISIS because its state-building project is over, there is no more caliphate, and that will diminish support and recruits,” said Hassan Hassan, a senior fellow at the Tahrir Institute for Middle East Policy in Washington, D.C. “But ISIS today is an international organization. Its leadership and its ability to grow back are still there.”
ISIS has overshadowed its jihadi precursors such as al-Qaida by not just holding territory, but by running cities and their hinterlands for an extended period, winning the group credibility in the militant world and allowing it to build a complex organization.
So even while its physical hold slips, its surviving cadres — middle managers, weapons technicians, propagandists and other operatives — will invest that experience in the group’s future operations.
And even though its hold on urban centers is being shaken, ISIS is not homeless.
In Iraq, the group still controls Tal Afar, Hawija, other towns and much of Anbar province. In Syria, most of its top operatives have fled Raqqa in the past six months for other towns still under ISIS control in the Euphrates River valley, according to U.S. and Western military and counterterrorism officials who have received intelligence briefings.
Many have relocated to Mayadeen, a town 110 miles southeast of Raqqa near oil facilities and with supply lines through the surrounding desert.
They have taken with them the group’s most important recruiting, financing, propaganda and external operations functions, U.S. officials said. Other leaders have been spirited out of Raqqa by a trusted network of aides to a string of towns from Deir el-Zour to Abu Kamal.
U.S. special-operations forces have targeted this area heavily with armed Reaper drones and attack planes, disrupting and damaging ISIS’ leadership and ability to carry out plots.
It is all a new chapter in the history of a group whose roots go back to the U.S. invasion of Iraq in 2003.
Fighting under various names and leaders, the Sunni militants who would evolve into ISIS killed many Iraqis and U.S. troops before Sunni tribal fighters paid by the United States turned on them, driving the survivors underground by the time the United States withdrew from Iraq in 2011.
New conflicts provided new opportunities. After the outbreak of the civil war in Syria in 2011, the group sent operatives there to build the force that later seized the country’s east, including Raqqa, which became its administrative capital.
Then it turned its sights back to Iraq, seizing Mosul in 2014, where al-Baghdadi made clear what distinguished his followers from al-Qaida: They were not just insurgents, but also the founders of a state infused with extremist ideology.
Senior U.S. intelligence and counterterrorism officials say more than 60,000 ISIS fighters have been killed since June 2014, including much of the group’s leadership, and the group has lost about two-thirds of its peak territory.
But those officials, including Lt. Gen. Michael K. Nagata, one of the Army’s top special-operations officers, also acknowledged that ISIS had retained much of its ability to inspire, enable and direct terrorist attacks.
“When I consider how much damage we’ve inflicted and they’re still operational, they’re still capable of pulling off things like some of these attacks we’ve seen internationally, we have to conclude that we do not yet fully appreciate the scale or strength of this phenomenon,” Nagata said recently in an interview published by the Combating Terrorism Center at West Point.
ISIS has carried out nearly 1,500 attacks in 16 cities across Iraq and Syria after they were freed from the militants’ control, showing that the group has reverted to its insurgent roots and foreshadowing long-term security threats, according to a study, also published by the West Point center.
Internationally, ISIS has partly compensated for its losses at home by encouraging affiliates abroad — in Libya, Egypt, Yemen, Afghanistan, Nigeria and the Philippines — and by activating operatives elsewhere.
Between 100 and 250 ideologically driven foreigners are thought to have been smuggled into Europe from late 2014 to mid-2016, nearly all through Turkey after crossing a now rigidly enforced border, European intelligence officials say. But they may not be the most dangerous threat facing European authorities as long as ISIS ideology continues to motivate attackers.
A recent study by the Program on Extremism at George Washington University and the International Centre for Counter-Terrorism in The Hague, Netherlands, examined 51 successful attacks in Europe and North America from June 2014, after the declaration of the caliphate, until June 2017, revealing that only 18 percent of the 65 attackers were known to have fought in Iraq or Syria. Most were citizens of the countries they chose to strike.
Since the rise of ISIS, the United States and its allies have focused on breaking the group’s control of territory, but much less planning has gone into how communities damaged by jihadi rule will be rebuilt and governed afterward. Indeed, the jihadis’ departure could accelerate other conflicts.
In Syria, the United States has armed and supported a militia called the Syrian Democratic Forces, or SDF, to fight the jihadis. Most of its leaders are Kurds, many with roots in the Kurdistan Workers’ Party, or PKK, which the United States and Turkey consider a terrorist organization.
The group’s ascendance has angered Turkey, which considers it a threat, and many Syrian Arabs, who see it as a front for Kurdish empowerment at their expense. It also remains unclear how the bodies set up to govern areas seized from the jihadis can be financed so they can rebuild, restore services and provide security.
The administration of President Donald Trump has shown little interest in such measures, although experts consider them necessary to prevent the jihadis from returning.
“There is a tension in the U.S. approach, to avoid extended commitments and nation-building on one hand and the need to prevent the possibility of a jihadi resurgence in the future on the other,” said Noah Bonsey, an analyst with the International Crisis Group.
In Iraq, the defeat of ISIS in Mosul sets the stage for new power struggles between the central government in Baghdad and the Kurds, who have taken control of the contested, oil-rich city of Kirkuk and plan to vote on independence this year.
The fight against ISIS has also fueled the proliferation of Shiite militias, many of which are funded by Iran and are driven by a sectarian creed that has marginalized and worried Sunnis.
Many fear that with poor governance and sectarianism still the rule in Syria and Iraq, some reconstituted form of ISIS’ extreme Sunni Islamism could yet find support.
“All of these conditions in the end form the basic environment for the group,” said Hassan Abu Haniyeh, a Jordanian expert in extremist groups. “They formed the environment for it to start and spread, and now they are increasing, not decreasing.”
The caliphate also lives on in the virtual realm, as its operatives and supporters churn out propaganda, bomb manuals, encryption guides and suggestions for how to kill the largest number of people with trucks.
Many Syrians and Iraqis whose lives the jihadis have ravaged are glad to see them chased out, despite worries about the future.
“I am happy that Daesh is dying, but the fear of what might come next is killing this happiness,” said Ahmed Abdul-Qadir, a Raqqa native who was running an anti-jihadi media group in Turkey when gunmen he believes belonged to ISIS shot him in the jaw. He is now in France, and he communicated via Facebook chat because he is between surgeries that have made it hard to speak.
“It makes me wish that this whole organization would vanish and that no one who believes in its doctrine would remain alive,” he said.
