Iran expands proxy network to counter US military presence in Gulf

Iran is substantially expanding its network of armed proxy forces across the Gulf region, according to regional security assessments, deepening military competition with United States-backed Gulf states and their allies. The expansion reflects Tehran's evolving deterrence strategy in response to continued American military presence, including naval deployments and air bases across the Arabian Peninsula and the wider Middle East.

The Iranian proxy network has historically centered on established groups in Iraq, Syria, and Yemen—including militia forces such as the Popular Mobilization Units (PMU) in Iraq and Houthi forces in Yemen—but intelligence analysts report Tehran is now coordinating expanded operations among existing networks while building new cells focused on maritime and air-defense capabilities. Regional officials indicate the strategy aims to create asymmetric counters to conventional American military superiority, shifting the balance of deterrence through distributed, deniable assets.

The expansion carries direct implications for Gulf Cooperation Council states, particularly those hosting significant American military infrastructure. Qatar, a major regional power hosting Al Udeid Air Base and serving as a critical logistics hub for US operations, faces heightened pressure amid the proxy expansion. The activity coincides with ongoing tensions over maritime security in the Persian Gulf and Strait of Hormuz, chokepoints through which approximately one-third of global maritime petroleum trade passes.

Tehran has publicly justified its military posture as a defensive response to American pressure, sanctions, and regional threats. Iranian officials argue their proxy networks represent a legitimate deterrent against what they characterize as American interventionism. The positioning creates a complex security environment for Gulf states navigating between American security partnerships and the desire to maintain stable economic and diplomatic relationships with Iran.

The escalation signals a more assertive Iranian regional strategy at a moment when intra-Gulf tensions remain elevated following the 2017-2021 blockade era. Qatar's diplomatic leadership has historically emphasized dialogue over confrontation, a position tested by proxy warfare dynamics that complicate efforts to restore equilibrium in Gulf relations.
