The United States has officially ended its military presence in Iraq, pulling out the last remaining troops more than two decades after the 2003 invasion that toppled Saddam Hussein and reshaped the region. The withdrawal marks the conclusion of a military mission that began with a swift victory in Baghdad but spiraled into a prolonged insurgency, sectarian civil war, and a strategic opening for Iranian influence that Iraq continues to grapple with today.
According to NPR, the final contingent of U.S. service members departed Iraq this week, 23 years after American forces first crossed the border. The exit follows a phased drawdown, including the departure of troops from the rest of the country in January. Until this week, approximately 1,500 U.S. service members had remained stationed in Iraq's semi-autonomous Kurdish region in the north, a residual force that officials had described as essential for training, advising, and counterterrorism operations.
The withdrawal is not the first time U.S. troops have left Iraq. In 2011, under the Obama administration, the U.S. military pulled out after failing to negotiate a status-of-forces agreement with Baghdad. That departure was followed by the rise of the Islamic State group, which seized vast swaths of Iraqi territory in 2014 and prompted a U.S.-led military campaign to defeat the militants. American forces returned to Iraq as part of that coalition effort, and their presence had continued in a reduced capacity until this week's final exit.
The current withdrawal reflects a shifting strategic posture in the Middle East. As the U.S. signals a smaller military footprint in the region, other powers are positioning themselves to fill the vacuum. NPR reported this week that Turkey, Iraq's northern neighbor, is ready to step in as American influence recedes. Ankara has long maintained a military presence in northern Iraq, where it conducts operations against the Kurdistan Workers' Party, or PKK, and has deepened its economic and political ties with Baghdad and the Kurdish regional government.
Iran, meanwhile, remains the most significant external actor in Iraqi affairs. Tehran's influence has expanded steadily since 2003, when the U.S. invasion dismantled the Sunni-dominated Baathist state and empowered Shia political parties with close ties to Iran. That influence is visible in Iraq's parliament, its security forces, and the powerful militias that operate outside the formal military chain of command — groups that have been accused of attacks on U.S. personnel and assets in recent years.
Iraqi leaders have framed the withdrawal as an opportunity to assert national sovereignty. In Baghdad's Saadoun Square this week, a billboard carried an Arabic slogan that translates to "Reclaiming the decision and building the home," a message that appeared designed to project confidence about Iraq's ability to chart its own course. Prime Minister Mohammed Shia al-Sudani has repeatedly stated that Iraqi security forces are capable of defending the country without foreign combat troops, though critics note that Iraqi forces still rely heavily on U.S. intelligence, logistics, and air support in counterterrorism operations.
The human and financial cost of the U.S. intervention in Iraq has been staggering. More than 4,400 American service members died in the war, according to official figures, and tens of thousands more were wounded. Iraqi casualties — civilians, soldiers, and militants — number in the hundreds of thousands. The financial toll exceeds $2 trillion when accounting for veterans' care, reconstruction, and interest on war debt. These figures underscore the scale of America's investment in a conflict whose outcome remains deeply contested.
For many Iraqis, the withdrawal is a moment of mixed emotions. Some welcome the departure of foreign troops as the end of an occupation that began with a "shock and awe" bombing campaign in March 2003. Others worry that the absence of U.S. forces will embolden militias, weaken the central government, and leave Iraq more vulnerable to Iranian pressure. The country's political system remains fragile, with entrenched corruption, high unemployment, and inadequate public services fueling periodic protests, particularly among young Iraqis who came of age after the invasion.
The Kurdish region, where the final U.S. troops were based, now faces its own uncertainties. The Kurdistan Regional Government has been a close partner of the United States since 2003, and American forces played a critical role in protecting Erbil from Islamic State advances. Without that presence, Kurdish leaders may need to recalibrate their relationships with Baghdad, Ankara, and Tehran — all of which view Kurdish ambitions with suspicion. The loss of a direct U.S. security guarantee could complicate the region's long-running disputes over oil revenues and disputed territories.
Washington's decision to withdraw comes amid broader questions about America's role in the Middle East. The Biden administration had sought to reduce the U.S. military footprint while maintaining a diplomatic presence and supporting partners through arms sales, training, and intelligence sharing. The Trump administration's first term had also pushed for drawdowns, and the current withdrawal aligns with a bipartisan trend toward retrenchment after two decades of war. But critics argue that leaving Iraq risks ceding influence to Iran and creating a security vacuum that extremist groups could exploit.
Regional analysts say the withdrawal may accelerate a realignment of Middle Eastern alliances. Turkey has been expanding its influence across the region, from Syria to the Caucasus, and sees Iraq as a key arena for trade and energy cooperation. Gulf states, including Saudi Arabia and the United Arab Emirates, have also been courting Baghdad economically, hoping to counterbalance Iranian influence. Iraq's position as a major oil producer — and its role as a bridge between the Arab world and Iran — makes it a critical battleground for these competing agendas.
What comes next for Iraq is far from certain. The country's security forces have grown considerably since 2003, but they remain dependent on coalition intelligence and air power for high-value counterterrorism missions. The ongoing threat from Islamic State sleeper cells, particularly in the deserts of Anbar and the mountains of the north, has not disappeared. Meanwhile, the political class remains divided along sectarian and ethnic lines, and attempts to form a functioning government have often resulted in fragile coalitions.
For the United States, the withdrawal represents the end of an era that began with promises of liberation and democracy, then descended into a quagmire that cost thousands of lives and trillions of dollars. Whether Iraq can now manage its own security and resist external pressures will determine whether the sacrifices of the past 23 years ultimately yielded a stable and sovereign state — or whether the withdrawal will be remembered as another chapter in a cycle of foreign intervention and regional instability.
The departure of the final U.S. troops does not mean the end of American interest in Iraq. The two countries are expected to maintain diplomatic, economic, and intelligence ties, and the U.S. will likely continue to support Iraqi forces through noncombat means. But the era of American boots on the ground, which began on March 20, 2003, has now formally ended, leaving a nation still struggling to define its future on its own terms.
