The conclusion of Operation Inherent Resolve in Iraq represents a significant shift in the nation’s security landscape. On September 30, 2026, Chief Pentagon Spokesman Sean Parnell announced the end of the coalition’s military mission aimed at defeating the Islamic State of Iraq and Syria (ISIS). This development, following a partnership between the U.S. and Iraq that has spanned over a decade, marks a pivotal transition toward an Iraqi-led security initiative.
Transition to Iraqi-Led Security
According to Parnell, the “orderly departure” of coalition forces is a reflection of the progress made in the fight against ISIS. The successful military campaign that began over 12 years ago has transformed the threat posed by ISIS from an organized military force to a more manageable challenge. The conclusion aligns with a joint statement between the U.S. and Iraq made in September 2024, emphasizing the importance of national interests in both countries.
Parnell highlighted that Iraqi Security Forces, including the Peshmerga, will now take the helm of ongoing security operations. This transition underscores a movement from the coalition’s wartime efforts to a bilateral security relationship that will better serve Iraqi sovereignty. The U.S. will continue to lend targeted training and intelligence support to help Iraq tackle its remaining security challenges, particularly those posed by ISIS remnants.
Future Security Cooperation
Despite the end of active combat support, U.S. commitment to counterterrorism in Iraq remains steadfast. Parnell stated that the responsibility of addressing security challenges, including hostile militias aligned with Iran, now lies primarily with the Iraqi government. He reassured that the United States remains dedicated to ensuring ISIS cannot regain a foothold within Iraq’s borders.
The coalition, initially formed in 2014, was instrumental in providing Iraqi forces with crucial air and intelligence support after ISIS captured significant territories in Iraq and Syria. By December 2017, Iraq declared full control over regions previously held by ISIS, marking a defining moment in its efforts to reclaim stability and security.
Looking Ahead
The transition from a coalition-led operation to an Iraqi-directed security initiative signifies a new chapter in U.S.-Iraq relations. The agreement reached in September 2024 established a timetable for the coalition’s military mission to conclude by September 2026. This decision reinforces both countries’ aims for a cooperative future, focusing on strengthening Iraq’s sovereignty and promoting deeper diplomatic, commercial, and security ties.
As the Iraqi government moves forward, the emphasis will be on maintaining stability and addressing ongoing security issues while fostering a sustainable environment for development. The enduring partnership between Iraq and the U.S. is set to evolve, with a mutual goal of ensuring a resilient and secure Iraq. This conclusion of Operation Inherent Resolve not only signifies military success but also serves as a foundation for a stable future in the region.
