US Troops Complete Withdrawal From Iraq, Ending Two-Decade Military Presence

The final contingent of U.S. troops formally withdrew from Iraq today, concluding a military presence that began with the 2003 invasion and returned years later to combat the Islamic State group. This phased drawdown, initiated under the Biden administration, signifies the end of a prolonged and often contentious period in American foreign policy.

The U.S. initially deployed tens of thousands of troops to Iraq as part of the broader War on Terror. These forces departed in 2011, but a smaller contingent later returned in 2014 to counter the Islamic State's resurgence. Over two decades, the conflict resulted in the deaths of more than 4,500 American service members and significant civilian casualties.

Periodic protests against American intervention have occurred in Iraq, fueled by concerns over civilian deaths and perceived violations of the country's sovereignty. The withdrawal, while marking a significant moment, has been a gradual process over recent years.

The departure, however, leaves a geopolitical vacuum that analysts suggest could benefit Iran. Iranian-backed militias have celebrated the U.S. withdrawal, with one commander calling it a "crushing defeat for the American project." Iran, historically an adversary of Iraq, intensified its efforts to build political and military influence following the U.S. toppling of Saddam Hussein in 2003. Tehran has cultivated ties with powerful figures and paramilitary groups, invested in infrastructure, and supported pilgrimage sites.

Concerns have been raised that the complete withdrawal of U.S. troops could embolden Iranian-linked groups. Ordinary Iraqis have expressed fears that their country could be "swallowed up" by these factions. The Iraqi government had previously set a deadline for these groups to disarm, coinciding with the official date of the U.S. withdrawal, a deadline that has reportedly been extended.

The U.S. military withdrawal from Iraq highlights the challenges of achieving desired political outcomes even after achieving military objectives. The long-term strategic competition with nations like Iran, which appear willing to engage in protracted influence campaigns, presents an ongoing dynamic in the region. The U.S. involvement in Iraq, marked by its ebb and flow, may have created openings for rivals like Tehran to expand their reach.
