US Troop Withdrawal From Iraq Is Complete, Pentagon Confirms, Ending 12-Year Mission

The United States has formally completed its withdrawal of troops from Iraq, the Pentagon confirmed Wednesday, closing a 12-year chapter of military involvement that began with the 2014 fight against the Islamic State and bringing to an end more than two decades of an on-and-off American military footprint in the country since the 2003 invasion.

The final convoy of roughly 1,500 American and coalition personnel departed Erbil Airbase in Iraq’s Kurdistan Region, the last installation still housing U.S. forces after a phased consolidation that saw troops pulled from Iraq’s other bases over the past year. Pentagon spokesman Sean Parnell called the departure an “orderly” one and said the milestone “reflects the success of a 12-year campaign that defeated ISIS as an organized military threat in Iraq and across the region.”

A Mission That Spanned Two Decades, With a Gap in the Middle

The American military presence in Iraq traces back to the 2003 invasion that toppled Saddam Hussein, part of what was then called the Global War on Terror. At its peak in 2007, roughly 170,000 U.S. troops were stationed across the country. The first major withdrawal came in 2011 under the Obama administration, which brought the mission to what was supposed to be a close.

That ended in 2014, when the rapid territorial expansion of the Islamic State group across Iraq and Syria prompted Washington to send a smaller force back in, this time under Operation Inherent Resolve, a U.S.-led coalition built specifically to roll back ISIL’s self-declared caliphate. That second deployment is the one now winding down. In 2024, the Biden administration and then-Iraqi Prime Minister Mohammed Shia’ al-Sudani agreed on a framework to wind the mission down over time, and over the past year the bulk of American forces were pulled from Iraq’s other bases, consolidating into the Kurdish region before Wednesday’s final departure.

President Trump’s Framing: “A Very Expensive Excursion Into Hell”

President Trump characterized the two-decade American involvement in blunt terms, describing it as “a very expensive excursion into Hell” while calling the completed withdrawal “a decisive victory” for the United States. The framing fits a broader pattern from the administration, which has sought to present the end of the Iraq mission as proof that the costly, open-ended deployments of the post-9/11 era can be brought to a close on American terms rather than dragged out indefinitely.

Trump also singled out Iraqi Prime Minister Ali al-Zaidi for praise, crediting the political trajectory that led to the current moment, even as he took credit for the decision to finally pull troops out after years of American presence that spanned multiple administrations of both parties.

Baghdad Calls It a Sovereignty Milestone

Iraqi officials, for their part, framed the withdrawal in sharply different terms from Washington’s victory-lap messaging, casting it instead as a long-awaited assertion of Iraqi independence. Prime Minister Ali al-Zaidi described the moment as the beginning of “a new phase, one defined by Iraq’s sovereignty, the strength of its institutions,” and called for increased regional investment now that the foreign military presence has ended. Al-Zaidi also emphasized that Iraqi security forces are prepared to continue anti-Islamic State operations on their own, without direct American boots on the ground.

That messaging was echoed, in far more triumphant and adversarial terms, by Iran-aligned militia groups operating in Iraq. A spokesman for Kataib Hezbollah, identified as Abu Mujahid al-Assaf, declared that “the expulsion of the occupation forces, defeated, from the land of Iraq is the beginning of full sovereignty,” language that underscores how differently the same event is being read by different factions inside the country. The umbrella group known as the Islamic Resistance in Iraq, which includes several Iran-backed militias, went further, stating it remains “not bound by any timeline or agreement” when it comes to disarmament, a pointed signal to Baghdad and Washington alike that armed groups outside government control are not treating the American departure as the end of their own activity.

The Backdrop: A Region Already at War

The timing of the withdrawal is inseparable from the wider regional context it is occurring in. Since February 28, 2026, the United States and Israel have been engaged in an active military conflict with Iran, now approaching its seventh month. That war has reshaped the strategic calculus for every actor in the region, including the Iran-backed militias operating inside Iraq that have periodically targeted American forces and interests during the conflict.

Those same militias have also coordinated, alongside Yemen’s Houthi movement, in attacks on Saudi Arabia during the same period, illustrating how the Iraq withdrawal is unfolding not in isolation but against the backdrop of a wider web of regional confrontation involving Iran and its network of aligned armed groups across multiple countries.

Disarmament Deadline Pushed Back to 2027

One of the thornier unresolved pieces of the drawdown involves the disarmament of militias operating inside Iraq, many of them aligned with Iran. The original target for getting a handle on these groups’ weapons was set for September 30, 2026, the same day as the troop withdrawal. That deadline has now been postponed by Prime Minister al-Zaidi to June 2027, an acknowledgment that only a handful of smaller, less significant militias have actually surrendered weapons under the agreement.

The more powerful Iran-aligned factions, including groups like Kataib Hezbollah, have either rejected disarmament outright or attached conditions to any cooperation that officials consider unachievable in the near term. That leaves Baghdad in the position of having secured a symbolic sovereignty win over the American withdrawal while still lacking a clear mechanism for reining in the armed groups operating within its own borders, some of which answer more directly to Tehran than to the Iraqi state.

Kurdish Officials Voice Anxiety Over What’s Left Behind

Not every Iraqi constituency is celebrating. Officials in the Kurdistan Region, the last part of the country to host departing American forces, have expressed real concern about the vacuum the withdrawal could leave behind. Kurdish leaders pointed to more than 1,000 drone and ballistic-missile attacks the region absorbed during recent rounds of conflict, and voiced specific worry about the removal of U.S. air defense systems that had been providing a layer of protection against exactly that kind of strike.

The fear in Erbil and across the broader Kurdish region is twofold: that the departure of American forces removes a deterrent against Iranian missile and drone attacks, and that it simultaneously creates more operating space for a resurgent Islamic State, which the Pentagon itself has acknowledged has been reduced to “scattered sleeper cells” rather than eliminated outright.

What Happens to the Remaining U.S. Footprint in the Region

The completed Iraq withdrawal does not mean an end to American military presence in the broader area. Hundreds of U.S. troops remain stationed in neighboring Syria, and the operations task force that had been coordinating activity from Iraq has been relocated to Jordan rather than withdrawn from the region entirely. The Pentagon has also pledged to continue providing what it describes as “targeted training and intelligence support” to Iraqi forces going forward, even without a standing troop presence inside the country.

That arrangement reflects a broader pattern in how the United States has approached its post-occupation posture in the Middle East: rather than a clean break from the region, the Iraq withdrawal represents a repositioning, with American resources shifted to adjacent countries where a presence is seen as less politically costly, even as Washington continues to describe a strategic pivot toward Asia that officials acknowledge has been inconsistently executed in practice.

A Moment Twenty-Three Years in the Making

For a generation of American service members, policymakers, and the Iraqi civilians who lived through it, Wednesday’s announcement closes a loop that opened with the 2003 invasion, a war whose justifications, costs, and consequences have been debated continuously in the years since. The 2011 withdrawal was supposed to mark the end; instead, the rise of the Islamic State three years later proved how quickly a declared end to American military involvement in Iraq could be reversed by events on the ground.

Whether this latest withdrawal proves more durable than the first will depend heavily on factors outside Washington’s direct control: whether Iraqi security forces can keep Islamic State remnants suppressed without American air power and intelligence backing them up day to day, and whether Iran-aligned militias operating inside Iraq choose to respect the sovereignty framework Baghdad is now asserting or continue to act as an independent armed force answerable to no one but themselves. With the disarmament deadline already pushed back once, and a regional war with Iran still actively underway, the question of whether this is truly the final American departure from Iraq remains, for now, unanswered.

How the Withdrawal Compares to 2011

Military analysts have been quick to draw comparisons between this withdrawal and the one in 2011, and the differences are instructive. The 2011 pullout happened against a relatively quiet security backdrop, with al-Qaeda in Iraq diminished and no immediate successor insurgency visible on the horizon; within three years, that calculation proved disastrously wrong as the Islamic State swept across huge portions of Iraqi and Syrian territory. This time, the Pentagon is withdrawing while explicitly acknowledging that ISIS has not been eliminated, only reduced to a dispersed network of sleeper cells, a far more cautious characterization than the triumphant language used in 2011.

That more guarded framing appears deliberate. Rather than declaring victory over the Islamic State outright, officials have repeatedly stressed that Iraqi forces will need continued American training and intelligence support even without troops stationed inside the country, a hedge against repeating the mistake of assuming a quiet security environment will stay quiet. Whether that lighter-footprint model of support, delivered from neighboring Jordan and Syria rather than from bases inside Iraq itself, can actually substitute for the real-time intelligence and air support a troop presence provided is a question that will only be answered over the months and years ahead, as Iraqi forces are tested without the safety net that has been in place, in one form or another, since 2014.
