Anti-ISIS Operations (Iraq & Syria)

The strategic environment in Syria has undergone a profound transformation in recent months, marked by significant political shifts, the complete withdrawal of foreign ground forces, and a subsequent re-evaluation of the counter-terrorism landscape. Following the collapse of the previous Syrian administration in December 2024, a new government, led by a figure with a past affiliation to a militant group, assumed control. This transition has been a pivotal development, influencing both internal dynamics and international engagement in the region. A critical element of this evolving situation is the complete withdrawal of foreign ground forces from Syria, which concluded in mid-April 2026. This withdrawal, ending a decade-long military presence focused on combating extremist elements, followed a period of intense negotiations and integration efforts between the Kurdish-led Syrian Democratic Forces (SDF) and the new Syrian government. The integration process, though complex and challenging, has seen the establishment of four Kurdish brigades, comprising approximately 5,200 soldiers, now formally incorporated into the Syrian Ministry of Defense's chain of command. Additionally, around 10,000 Kurdish local security forces, including a notable contingent of 1,000 women, are slated for integration into the Ministry of Interior. This phased integration was preceded by a ceasefire agreement in January 2026, mediated by international actors, which aimed to facilitate a more orderly transfer of control in northeastern Syria. However, this period of transition has been fraught with instability and has generated considerable concern regarding the potential for a resurgence of extremist groups. Intelligence assessments from various international bodies and regional security services have highlighted a growing threat. One intelligence estimate from early 2026 suggested that the number of extremist operatives in Syria had swelled from approximately 2,000 to as many as 10,000 within a year, though other reports indicated a combined total of around 3,000 operatives across both Syria and Iraq. This discrepancy underscores the difficulty in obtaining precise figures but consistently points to an upward trend in extremist activity. The instability was particularly evident in January 2026, when a major escape of over 15,000 extremist-affiliated detainees occurred from a significant camp in northeastern Syria, previously under Kurdish control. This incident, attributed to the failure of Syrian authorities to adequately contain the facility following the withdrawal of Kurdish forces, raised immediate alarms about the re-entry of battle-hardened individuals into militant networks. Further reports indicated that around 200 lower-level extremist suspects also escaped from another prison in the region, with many subsequently recaptured, but the incidents collectively highlighted critical vulnerabilities in detention facility security. The strategic implications of these developments are significant. The previous administration's counter-terrorism strategy had heavily relied on the Kurdish-led forces as a primary partner. With their integration into the Syrian government and the departure of foreign ground troops, questions have arisen about the immediate capacity of the new Syrian government to effectively counter extremist elements. While the new government has expressed its commitment to fighting extremism and has engaged in intelligence sharing with international partners, concerns persist about its ability to replicate the extensive operational experience, intelligence networks, and local security infrastructure developed by the Kurdish-led forces over the past decade. Indeed, some analyses suggest that the extremist group has been actively positioning itself to exploit these shifting dynamics. Reports from early 2026 indicated that the group had established networks across all Syrian governorates, embedding sleeper cells in urban centers, including the capital. The group's spokesperson also released an audio message in early 2026, urging members to target the Syrian government, signaling an intent to capitalize on the foreign troop withdrawal. However, there are also counter-narratives emerging. Some reports from mid-2026 suggest a notable decline in extremist attacks following the defeat of the Kurdish-led forces in January 2026 and the subsequent foreign troop withdrawal. One analysis indicated a 17% decline in attacks between January and April 2026, followed by a further 67% plunge after the foreign forces departed, with May 2026 recording the lowest number of attacks and fatalities since the group's emergence in Syria in 2013. This perspective posits that the extremist group had primarily exploited Arab discontent under Kurdish-led administration, and the shift in control, paradoxically, removed a key grievance that fueled recruitment and operations. Syrian forces have also reported success in capturing key extremist leaders, including the overall leader for Syrian operations and commanders for specific regions, through methodical infiltration and intelligence gathering. Geopolitically, the situation remains complex. The new Syrian government has been recognized by some international actors as the primary partner in counter-terrorism efforts, a role previously held by the Kurdish-led forces. This shift has led to increased coordination between the Syrian government and some international powers, even as the new Syrian leadership's past affiliations remain a point of contention for others. The broader regional context, including escalating tensions involving other state and non-state actors, further complicates the counter-terrorism efforts, as extremist groups often thrive in environments of regional instability. The long-term stability of Syria and the enduring defeat of extremist elements will depend heavily on the new government's ability to consolidate control, address underlying grievances, and effectively manage the security vacuum created by the recent transitions.

Iraqi Security Forces (ISF) have significantly intensified their anti-extremist operations across the country, particularly in provinces known for persistent extremist activity, while simultaneously undertaking a substantial effort to bolster border security with neighboring Syria. These actions come in response to ongoing threats from extremist remnants and heightened concerns about regional instability, including the potential for extremist elements to exploit the evolving security landscape in Syria. Recent tactical successes include an airborne operation in Kirkuk province in July 2026, where special forces identified and destroyed six suspected extremist hideouts in the Zghitun Valley area. This region, located east of Hawija district, has historically been a hotbed for extremist activity. The operation involved precise airstrikes targeting these facilities, which are often used for shelter and logistical support. Earlier in the same month, the Iraqi Air Force conducted airstrikes that destroyed eight extremist hideouts in Kirkuk, further demonstrating a sustained offensive posture. These operations are part of a broader strategy to eliminate remaining extremist cells, which, despite the territorial defeat of the group in Iraq in 2017, continue to pose a threat through sporadic hit-and-run attacks and operations in remote areas. Beyond direct military engagements, Iraqi security agencies have also been active in intelligence-led operations. The Kurdistan Region Security Agency, in coordination with the national Counter-Terrorism Service, successfully apprehended two suspected extremist members in Sulaimani province in June 2026. These arrests, conducted in separate operations, also led to the rescue of the wife and child of one of the apprehended individuals, who had been held captive. These efforts highlight the multi-faceted approach of Iraqi forces, combining kinetic operations with intelligence gathering and law enforcement actions. However, the fight remains dangerous, as evidenced by the death of a Counter-Terrorism Service personnel during clashes with extremist militants in Kirkuk province earlier in July, following a series of security operations. A major strategic and logistical undertaking for Iraq has been the transfer of thousands of extremist-linked detainees from Syrian prisons to Iraqi facilities. This process, initiated in January 2026 with the assistance of international forces, involved an initial transfer of 150 detainees, with plans to relocate up to 7,000 individuals in the coming weeks. This move was proactively proposed by Iraq to prevent mass escapes from deteriorating prisons in northeastern Syria, which were seen as a "time bomb" that could directly threaten Iraqi cities like Mosul and Anbar. The Iraqi Supreme Judicial Council has stated its intention to initiate proper legal proceedings against all transferred detainees, regardless of their national origins, under Iraq's strict anti-terrorism legislation, which includes the application of the death penalty. This transfer, while necessary to mitigate immediate risks in Syria, presents a significant long-term security challenge for Iraq, as these battle-hardened individuals could potentially seek to reconstitute insurgent operations from within the Iraqi justice and penal systems. Concurrently, Iraq has significantly tightened security along its extensive border with Syria. Fears of a potential extremist resurgence, fueled by instability across the border and the aforementioned prison escapes, have prompted the deployment of thousands of troops and militia members to reinforce the frontier. Advanced defensive systems have been constructed, including five integrated layers of border barriers comprising earth embankments, trenches, barbed obstacles, BRC fencing, and concrete walls. These physical barriers are complemented by electronic surveillance and thermal cameras, ensuring comprehensive coverage of the entire area. Border forces are maintaining a 24-hour, continuous state of readiness, emphasizing that the threat has strengthened their resolve to prevent infiltration. The Iraqi government's proactive stance on border security and counter-terrorism operations is underscored by its concerns about the growing numbers of extremist militants in Syria. Iraqi intelligence estimates, as articulated by senior security officials, indicate a substantial increase in extremist presence across the border, posing a direct danger to Iraq given the transnational nature of the extremist organization. This concern is further amplified by the ongoing political transition in Syria and the perceived security vacuum in certain areas. The withdrawal of international coalition advisors from all military bases and command centers in federal Iraq, completed in January 2026, has placed the primary responsibility for counter-insurgency operations squarely on the ISF. While the ISF has demonstrated increased capacity to conduct operations independently, the continued support for counter-extremist operations in Syria from Iraq, facilitated by the international coalition until at least September 2026, highlights the interconnectedness of the security challenges in both countries. The Iraqi government's efforts are crucial not only for its own national security but also for regional stability, as it seeks to prevent any re-establishment of extremist safe havens that could threaten the wider Middle East.

Despite sustained counter-terrorism efforts by national and international forces, the extremist group continues to demonstrate remarkable resilience and adaptability, exploiting regional instability and leveraging new technologies to maintain its operational capabilities and expand its influence. Recent intelligence assessments and operational reports from both Iraq and Syria underscore that the group, though territorially defeated years ago, remains a persistent and evolving threat. A significant concern highlighted by various intelligence sources is the group's ability to swell its ranks, particularly in Syria. Iraqi intelligence estimates from early 2026 suggested a dramatic increase in the number of extremist operatives in Syria, potentially rising from approximately 2,000 to as many as 10,000 within a year. While other international reports provided a more conservative combined estimate of around 3,000 operatives across both Syria and Iraq, the consensus points to a growing presence and operational tempo. This resurgence is attributed to the exploitation of security vacuums and sectarian tensions, particularly in the context of Syria's political transition following the collapse of the previous administration in late 2024. The group's adaptability is evident in its operational tactics. It primarily conducts small-scale, hit-and-run operations, taking advantage of security blind spots and remote areas. These tactics are designed to harass security forces, maintain a presence, and demonstrate continued relevance, even without holding significant territory. In Syria, the group has reportedly established networks across all governorates, embedding sleeper cells in urban centers, including the capital. This strategy allows for a decentralized insurgency, making it harder to track and dismantle. A critical factor contributing to the group's potential resurgence is the security of detention facilities and displacement camps. The escape of over 15,000 extremist-affiliated detainees from a major camp in northeastern Syria in January 2026, following the withdrawal of Kurdish-led forces, provided a significant pool of individuals who could potentially re-enter militant networks. Similarly, the transfer of thousands of extremist detainees from Syrian prisons to Iraqi facilities, while aimed at preventing escapes, also presents a long-term challenge for Iraq in managing and preventing the reconstitution of insurgent operations from within its penal system. Beyond direct military and security challenges, the extremist group is also adapting its methods in the digital sphere. Intelligence reports indicate an enhanced use of new and emerging technologies, including cryptocurrencies for financing and drones for operational purposes. Alarmingly, the group is increasingly employing artificial intelligence, particularly for radicalization and recruitment, with a deliberate focus on targeting youth and children. This sophisticated approach to propaganda and recruitment, including the development of multilingual content, aims to expand its global reach and inspire attacks beyond its core operational areas. The threat posed by the extremist group is not confined to Iraq and Syria. Its affiliates continue to operate globally, with heightened concerns in regions such as the Sahel in Africa, where they are expanding activities and honing skills, including the use of unmanned aerial systems. There are also growing concerns that these affiliates could shift resources towards conducting external operations, posing a threat to international security. The group has been linked to numerous high-profile terrorist attacks worldwide, including recent incidents in Australia and the New Orleans attack in 2025, demonstrating its continued ability to inspire or orchestrate violence far from its traditional strongholds. The group's ability to exploit governance vacuums and incite sectarian tensions remains a core element of its strategy. In Syria, the political transition and the integration of various armed groups have created a complex environment that the extremist group seeks to leverage. While some analyses suggest a decline in attacks in Syria following recent political and military shifts, the underlying conditions that allow the group to persist, such as unresolved instability and grievances, remain a concern. Strategically, the extremist group's long-term objective appears to be the re-establishment of a territorial caliphate, or at least a significant sphere of influence, by exploiting any perceived weaknesses or divisions among its adversaries. Its continued focus on attacking critical infrastructure, such as oil tanker trucks and facilities, in northern and eastern Syria, is part of an "economic war" aimed at destabilizing the Syrian state and other anti-extremist actors. The ongoing efforts to counter this adaptable and resilient threat require not only sustained military pressure but also comprehensive approaches that address underlying socio-economic and political factors, coupled with robust international cooperation to counter its evolving tactics, particularly in the digital domain.

The international coalition's role in anti-extremist operations in Iraq and Syria is undergoing a significant transition, marked by the formal conclusion of its military mission in Iraq and a strategic realignment of counterterrorism priorities by major global powers. This evolution reflects both the successes achieved in degrading the extremist group's territorial control and the persistent, yet changing, nature of the threat. Operation Inherent Resolve (OIR), the operational name for the international campaign against the extremist group, has seen its military mission in Iraq formally conclude in September 2025. This transition was part of a two-phase plan agreed upon by the international coalition and the Iraqi government. While the combat mission in Iraq ended, the coalition continues to provide advise, assist, and enable functions to Iraqi Security Forces (ISF) and Kurdish Security Forces, supporting their independent efforts to prevent a resurgence of the extremist group. This support includes logistical assistance and training, with the ISF now having full responsibility for training facilities and programs. The continuation of OIR in Iraq is also intended to support counter-extremist operations in Syria from Iraqi territory until at least September 2026, underscoring the interconnectedness of the security challenges in both nations. In Syria, the landscape of international involvement has seen an even more dramatic shift. The complete withdrawal of foreign ground forces from northeastern Syria occurred in mid-April 2026, ending a decade-long presence. This withdrawal followed a period of integration between the Kurdish-led Syrian Democratic Forces (SDF), previously a key partner in counter-extremist efforts, and the new Syrian government. While the international coalition previously conducted advising through partnered patrols with the SDF and combined exercises, the new dynamic necessitates a re-evaluation of how support is provided in Syria. The transition has raised concerns about the capacity of the new Syrian government to immediately replace the SDF as a reliable counter-extremist partner, particularly regarding human intelligence networks and specialized counter-extremist forces. Concurrently, a major global power has articulated a revised counterterrorism strategy that represents a notable departure from previous approaches. Released in May 2026, this strategy identifies global extremist groups and certain state actors as major concerns but also expands the parameters of counterterrorism to include transnational criminal organizations and certain domestic extremist movements. A key shift in emphasis is the prioritization of combating criminal organizations in the Western Hemisphere, which some analysts suggest could lead to fewer resources being allocated to critical priorities elsewhere, including the Middle East. The strategy also contends that, due to growing domestic energy production, the Middle East is no longer as central to national stability, potentially underplaying discrete threats from the region. Despite this strategic reorientation, the global power has continued to conduct targeted strikes against extremist elements. For instance, in late January and early February 2026, its forces conducted multiple strikes against extremist targets across Syria, destroying communication sites, logistics nodes, and weapons storage facilities. These operations were launched in response to an attack on its forces and Syrian partners in December 2025, which resulted in fatalities. Such actions demonstrate a continued resolve to prevent an extremist resurgence, even as the broader strategic focus evolves. The international coalition, comprising over 80 nations and four international organizations, remains committed to the enduring defeat of the extremist group. However, the nature of this commitment is adapting to the changing realities on the ground. In Iraq, the coalition operates at the invitation of the government, working to support local, regional, and international actors in bringing stability to conflict-affected areas. The transition of the military mission in Iraq and the withdrawal of ground forces from Syria signify a shift towards enabling partner forces to independently manage the threat, rather than direct combat intervention. Geopolitically, the broader Middle East is experiencing heightened tensions, including escalating conflicts involving certain state actors and their proxies. These regional dynamics can indirectly impact counterterrorism efforts by creating environments that extremist groups can exploit or by diverting resources and attention from the fight against them. The evolving counterterrorism strategies and the transitioning roles of international actors will be critical in shaping the future trajectory of anti-extremist operations in Iraq and Syria, requiring continuous adaptation and robust international cooperation to address the complex and interconnected security challenges.
