US TROOP WITHDRAWAL FROM IRAQ RAISES CONCERNS OVER IRANIAN INFLUENCE AND REGIONAL SECURITY

September 29, 2026

The United States is preparing to withdraw its remaining forces from Iraq by September 30, 2026, bringing an end to a military presence that began with the 2003 invasion. The withdrawal, agreed upon in 2024 and implemented under President Donald Trump’s administration, marks a significant change in the US military role in the Middle East.

The departure is being welcomed by Iran and its allied armed groups in Iraq, which regard the withdrawal as a strategic gain. Iraqi security analysts have warned that the absence of US forces could expand Tehran’s influence over Iraq’s security and political institutions, potentially strengthening Iran-backed militias operating within the country.

The withdrawal has also raised concerns among some Iraqi officials and security experts about the readiness of national forces to independently manage the country’s security. While the move is supported by many Iraqis who seek greater national sovereignty, others fear that a security vacuum could emerge, particularly in areas where armed factions maintain considerable influence.

Another major concern is the possible resurgence of the Islamic State (ISIS), which continues to maintain sleeper cells despite losing its territorial strongholds in Iraq. Kurdish security officials have warned that reduced access to American intelligence, logistical assistance and surveillance capabilities could create opportunities for the militant group to reorganise and conduct attacks.

Iraq has long sought to maintain diplomatic and security relationships with both Washington and Tehran, despite their competing regional interests. The departure of US forces could further complicate this balancing effort as Baghdad attempts to strengthen its national security institutions while managing the influence of domestic armed groups.

The withdrawal represents a major transition in Iraq’s post-2003 security landscape. Its longer-term consequences will depend on the capabilities of Iraqi security forces, the influence of Iran-aligned militias and the government’s ability to prevent extremist groups from exploiting potential security gaps.
