US Military Completes Withdrawal of Troops From Iraq After 12-Year Mission

The last American combat troops have left Iraq, ending a mission that began with the 2003 invasion and cost thousands of lives. The withdrawal marks a pivotal moment in US foreign policy and Iraq’s struggle for stability.

**Lead**

The United States military has completed the withdrawal of its remaining combat troops from Iraq, officially ending a 12-year mission that began with the 2003 invasion and toppled Saddam Hussein. The final convoy of American soldiers crossed into Kuwait early this morning, bringing to a close the longest sustained US military operation since the Vietnam War. The departure fulfills a pledge made by President Barack Obama to remove all US forces from Iraq by the end of 2011, after negotiations with the Iraqi government failed to secure an agreement that would grant legal immunity to American troops beyond that date.

**Context**

The US-led invasion of Iraq in March 2003 was launched under the premise of eliminating weapons of mass destruction that were never found. Within weeks, Saddam Hussein’s regime collapsed, but the country quickly descended into a brutal insurgency and sectarian violence that claimed tens of thousands of lives. At the peak of the war in 2007, the United States had approximately 170,000 troops deployed across Iraq, fighting a multifaceted conflict against Sunni insurgents, Shiite militias, and al-Qaeda affiliates. The surge strategy, implemented under General David Petraeus, helped reduce violence, but the human and financial costs were staggering: more than 4,400 American service members killed and over 30,000 wounded, alongside estimates of more than 100,000 Iraqi civilian deaths.

In August 2010, President Obama declared an end to combat operations, rebranding the mission as “Operation New Dawn” with a focus on training and advising Iraqi security forces. The transition was intended to allow the Iraqi government to take full responsibility for its own security. However, persistent political instability, corruption, and the rise of extremist groups like al-Qaeda in Iraq (the precursor to ISIS) raised concerns about the country’s ability to maintain order without a US military presence. Negotiations over a Status of Forces Agreement (SOFA) that would extend the US troop presence beyond 2011 collapsed over the issue of legal immunity for American personnel. Iraqi Prime Minister Nouri al-Maliki’s government, facing domestic political pressure, was unable to grant the protections the Pentagon deemed essential, leading to the full withdrawal.

**Analysis**

The completion of the withdrawal represents a significant milestone in US foreign policy, but its implications are deeply contested. Supporters of the pullout argue that the United States has fulfilled its obligation to help Iraq establish a democratic government and that continued military occupation was fueling resentment and instability. They point to the successful handover of security responsibilities to Iraqi forces, who have taken over bases and patrols across the country. Critics, however, warn that the departure creates a power vacuum that could be exploited by Iran, which has long sought to expand its influence in Iraq through political and militia networks. The absence of a US military buffer may also embolden Sunni insurgent groups, including the remnants of al-Qaeda, which have been regrouping in the western desert.

For the United States, the end of the Iraq mission allows the Pentagon to redirect resources toward other strategic priorities, including the war in Afghanistan and the growing focus on the Asia-Pacific region. The withdrawal also fulfills a key campaign promise for President Obama, who opposed the Iraq War from the outset. Yet the legacy of the conflict remains divisive. The war cost the US Treasury an estimated $800 billion, and the broader human toll—both American and Iraqi—continues to shape public opinion about military intervention. The question of whether Iraq can sustain a stable, pluralistic government without US troops will define the next chapter of the region’s history.
