The United States has completed the withdrawal of its remaining military forces from Iraq, ending a deployment that began in 2014 to combat the Islamic State.
The Final Departure From Erbil Completes the 2014 Mission
The final phase of the U.S. military drawdown concluded on September 30, with troops pulling out from Erbil in the Kurdish region of Iraq. While Washington plans to maintain bilateral security cooperation with Baghdad, no active combat or advisory troops will remain stationed within the country’s borders. This departure marks the second time U.S. forces have exited Iraq after a protracted engagement, following the initial post-invasion withdrawal in December 2011 and subsequent return three years later when the Islamic State seized vast swaths of territory.
Unlike the 2011 exit, which preceded a rapid security collapse, the current situation differs significantly. The Islamic State no longer holds major cities or territorial strongholds, though active underground cells persist. Iraqi security forces must now independently manage intelligence, surveillance, and counter-terrorism operations previously backed by American logistical and tactical support.
Baghdad Pushes Back Militia Disarmament Deadlines Amid Political Resistance
Anticipating the U.S. departure, the Iraqi government attempted to coordinate the exit of foreign troops with the consolidation of all domestic arms under state authority. Baghdad initially set September 30 as the final deadline for the disarmament of domestic militias, but major factions refused to comply, prompting officials to extend the timeline to June 2027.
The revised disarmament framework outlines an initial 90-day grace period free of armed conflict, followed by a phased surrender of weaponry. However, enforcing this policy presents deep structural challenges. Many of the armed groups operate under the umbrella of the Popular Mobilization Forces, known as Hashd al-Shaabi, which were established in 2014 to fight the Islamic State and were subsequently integrated into the official security apparatus.
While some factions have agreed to transition their arsenals into state inventories in exchange for formal security sector employment, the most powerful groups retain extensive autonomy. Organizations such as Kataib Hezbollah, Harakat al-Nujaba, and Kataib Sayyid al-Shuhada maintain close ties to Tehran and reject surrendering their arsenals, viewing their independent military capacity as a way to force political concessions.
Regional Tensions and the Balance of Power Between Tehran and Baghdad
The exit of American forces is framed by regional allies of Iran as a strategic victory following years of political pressure. Yet analysts note that characterizing the shift as a complete takeover by Tehran oversimplifies a complex domestic dynamic. The central government in Baghdad aims to prove it can govern independently and enforce a monopoly on state violence.
The friction between state authority and autonomous armed groups has introduced acute political risks. Kataib Hezbollah leadership has publicly threatened to destabilize the government if official policies conflict with what the faction defines as national interests, while also issuing warnings regarding regional cooperation with airspace restrictions targeting Iran.
In the Kurdish region of Iraq, local authorities have expressed deep anxiety regarding air defense capabilities. The area suffered drone and missile strikes during prior exchanges between Washington and Tehran, leaving regional leaders vulnerable as American air defense assets withdraw, even as Baghdad pledges to upgrade national airspace protection.
