The United States has officially concluded its military mission in Iraq, pulling out the last remaining troops more than two decades after the 2003 invasion that toppled Saddam Hussein's regime and unleashed years of insurgency and sectarian violence. The withdrawal marks the end of a controversial and costly chapter in American foreign policy, one that reshaped the Middle East and left a lasting imprint on Iraqi society.
According to NPR, the final withdrawal occurred on September 30, 2026, bringing to a close a military presence that began 23 years earlier. The departure of American forces comes as Iraq continues to grapple with the long-term consequences of the invasion, particularly the significant influence that neighboring Iran has established in Iraqi political and security affairs.
The U.S. military had already withdrawn the bulk of its forces from Iraq in January 2026, leaving approximately 1,500 service members stationed in the country's semi-autonomous Kurdish region in the north. Those remaining troops have now departed, marking the complete end of the American military footprint in the country.
The invasion of Iraq in 2003, launched by the administration of President George W. Bush, was justified at the time by claims that Saddam Hussein's government possessed weapons of mass destruction—claims that were never substantiated. The overthrow of Saddam's regime quickly gave way to a violent insurgency, followed by a brutal civil war that claimed the lives of hundreds of thousands of Iraqis and thousands of American service members.
The power vacuum created by the removal of Saddam's government also opened the door for Iran to expand its influence in Iraq. Tehran has cultivated deep ties with Shia political parties, militias, and security forces across the country, establishing a network of allies that has made Iraq a key arena in the broader regional competition between Iran and the United States and its Gulf allies.
Iraqi officials have publicly expressed a desire to reclaim their nation's independent decision-making, as evidenced by billboards in Baghdad bearing the Arabic slogan "Reclaiming the decision and building the home." The slogan reflects a growing sentiment among many Iraqis that their country should chart its own course, free from the competing pressures of foreign powers.
The U.S. withdrawal is part of a broader strategic shift in American foreign policy in the Middle East. As the United States signals a reduced military footprint in the region, other powers are positioning themselves to fill the void. Turkey, a NATO ally with its own complex relationship with Iraq, has signaled its readiness to expand its influence as American forces draw down.
This was not the first time the United States has withdrawn troops from Iraq. In 2011, under the administration of President Barack Obama, the U.S. pulled its forces out of the country, only to return in 2014 to help combat the Islamic State group, which had seized large swaths of Iraqi territory. That renewed deployment, initially framed as a limited advising and training mission, gradually expanded in scope and duration over more than a decade.
The human and financial costs of the Iraq War have been staggering. Estimates of Iraqi civilian deaths range from tens of thousands to well over a hundred thousand, with millions more displaced from their homes. The war also left deep scars on the U.S. military, with nearly 4,500 American service members killed and tens of thousands wounded.
Critics of the invasion and subsequent occupation argue that the withdrawal leaves Iraq in a perilous position, with Iranian-backed militias wielding significant power and the central government struggling to assert control over the entire country. Others contend that the U.S. presence had become unsustainable and that Iraqis must ultimately determine their own future without foreign military interference.
The departure of U.S. troops also raises questions about the future of counterterrorism operations in the region. American officials have emphasized that they retain the capability to conduct over-the-horizon missions against terrorist threats, but the absence of a ground presence in Iraq could complicate efforts to monitor and respond to emerging dangers.
For Iraq, the withdrawal represents both an opportunity and a challenge. The country must navigate a complex political landscape, manage delicate relations with Iran, Turkey, and Gulf states, and address pressing domestic issues including economic stagnation, corruption, and sectarian tensions. Whether Baghdad can assert genuine sovereignty remains an open question.
The Biden administration, which oversaw much of the final drawdown, framed the withdrawal as consistent with broader efforts to recalibrate American military priorities toward great-power competition with China and Russia. However, the decision has drawn criticism from some quarters who warn that abandoning Iraq could embolden Iran and create new security vacuums.
As the last American troops leave Iraqi soil, the legacy of the 2003 invasion remains deeply contested. Supporters of the withdrawal see it as the overdue end of a costly misadventure, while opponents view it as an abandonment of a nation that the United States helped destabilize. What is clear is that Iraq's future will now be shaped without the presence of American boots on the ground for the first time in more than a decade.
