US completes Iraq military withdrawal after 21 years, 4,500 deaths

The United States is concluding its longest sustained military engagement in the Middle East as it removes the last of its armed forces from Iraq by Wednesday. The withdrawal marks the end of a 21-year military presence that began with the 2003 invasion and has cost approximately 4,500 American military lives.

The pullout decision was initiated by the Biden administration in 2024 and is being executed by the incoming Trump government. The move has been characterized by Iran and its allied militias as a significant strategic victory, potentially reshaping the regional balance of power in their favor.

Security analysts have raised concerns that the departure will create a power vacuum, likely to be filled by Iranian-backed militia groups operating across Iraq and Syria. These regional actors have significantly expanded their influence over the past decade, and the removal of American military presence may accelerate their activities further.

The withdrawal represents a major shift in US Middle East policy, though the implications for Iraq's stability and the broader regional security architecture remain uncertain. Iraqi security forces, which have received extensive American training and support, will assume primary responsibility for counterterrorism operations and border security.
