U.S. Military to Conclude Mission in Iraq Amid Ongoing Security Challenges

<p>The U.S. military is scheduled to end its mission in Iraq on September 30, 2026, concluding a military operation that has lasted more than two decades. This decision comes despite ongoing tensions in the region, particularly due to a war in Iran that began earlier this year.</p><p>The mission in Iraq commenced with the 2003 invasion that removed Saddam Hussein from power and evolved into efforts to assist Iraqi forces in combating the Islamic State group following its rapid expansion in Iraq and Syria.</p><p>In recent years, the U.S. military presence has acted as a counterbalance to Iran's influence and has been targeted by Iran-backed militias.</p><p>The agreement for withdrawal was established prior to the escalation of direct conflict between the U.S. and Iran earlier this year and under a different administration, resulting in a withdrawal process that occurs in a significantly altered security context.</p><p>The withdrawal timeline was agreed upon by Washington and Baghdad in 2024 under President Joe Biden, following assessments by Iraqi officials that their security forces were increasingly capable of managing the fight against ISIS.</p><p>This withdrawal follows the U.S. military's departure from Afghanistan in 2021, which also concluded a two-decade military engagement, but was characterized by chaotic conditions that resulted in casualties among U.S. service members and civilians.</p><p>The Pentagon has not confirmed whether the withdrawal timeline remains on schedule or provided details on any ongoing U.S. military activities in Iraq post-withdrawal. The Iraqi Embassy has not responded to requests for comment.</p><p>Throughout the final months of the mission, threats to U.S. personnel persisted. Army Sgt. Michael Emmanuel Swinton was killed at Erbil Air Base in July during a controlled detonation of an Iranian attack drone.</p><p>Approximately 2,500 U.S. troops had remained in Iraq as part of Operation Inherent Resolve, a coalition formed in 2014 to combat ISIS. U.S. forces had previously withdrawn from Iraq in 2011 before returning in 2014 to assist local forces.</p><p>The threat from ISIS has reportedly diminished significantly. The Defense Intelligence Agency (DIA) noted this summer that ISIS in Iraq is “almost certainly severely degraded,” focusing on its survival and unable to exploit instability from the ongoing war with Iran, according to the latest Lead Inspector General report on Operation Inherent Resolve.</p><p>CENTCOM commander Adm. Brad Cooper informed lawmakers in May that ISIS attacks in Iraq and Syria had decreased by 70% since 2023, reaching their lowest levels since 2013.</p><p>As a result, the U.S. mission has shifted from direct combat to training, advising, and providing intelligence to local forces, who are expected to conduct counterterrorism operations with limited or no direct U.S. involvement.</p><p>The Pentagon has also begun relocating infrastructure out of Iraq, moving Operation Inherent Resolve's headquarters to Amman, Jordan, allowing U.S. personnel and assets to redeploy while Iraqi forces take on greater responsibility for counterterrorism efforts.</p><p>However, the declining ISIS threat has introduced new challenges for the Iraqi government, particularly from powerful Iran-backed armed groups that have resisted disarmament efforts.</p><p>The Iraqi government initially aimed to disarm these groups by September 30, 2026, with Prime Minister Ali al-Zaidi asserting that the withdrawal of U.S. forces would remove a key justification for the militias to remain armed.</p><p>While some factions agreed to disarm, others have refused, leading the Iraqi government to extend its timeline. Zaidi announced last week that the government now aims to complete disarmament by June 30, 2027, starting with a 90-day period in which armed groups would cease attacks in exchange for assurances that U.S. forces would not target them. The groups would then gradually disarm or come under state control.</p><p>These armed groups remain heavily equipped, with U.S. military officials reporting that they possess rockets, missiles, drones, and air defense systems that could threaten American personnel and facilities in the region.</p><p>The DIA reported that Iran-aligned militias have launched hundreds of attacks on U.S. forces and diplomatic facilities in Iraq since the onset of the war with Iran.</p><p>The conclusion of the U.S. mission occurs as the threat that initially necessitated American forces' return to Iraq has significantly decreased, while efforts to disarm groups that have targeted U.S. forces remain incomplete.</p>
