The Houthi Advance Is About More Than Just Iran

Foreign Policy | Marc Lynch

The Houthi military advance in Yemen is increasingly driven by the intensifying geopolitical rivalry between Saudi Arabia and the United Arab Emirates rather than solely by Iranian influence. This regional competition between Riyadh and Abu Dhabi shapes strategic alignments, threatening energy security, oil infrastructure, and broader maritime stability across the Middle East.

Underlying tensions between the two Gulf powers stem from divergent approaches to Yemen's southern transition, local governance, and control over strategic ports. Local proxy dynamics complicate international mediation efforts. As the United States and Israel monitor these shifting dynamics, the ongoing friction between the Gulf allies undermines cohesive coalition efforts to deter Houthi maritime strikes. Consequently, the fractured security architecture in the Red Sea allows the insurgent group to consolidate territorial gains, threaten global oil supply chains, and expand its operational reach. This unresolved competition ensures that the conflict will continue to destabilise regional trade routes and complicate Western security calculations.

Comment

The divergent strategic priorities of Riyadh and Abu Dhabi in Yemen expose structural vulnerabilities within the Saudi-led coalition's Joint Forces Command. While Saudi Arabia seeks a stable northern border through negotiated settlements with the Houthis, the United Arab Emirates continues to patronise the Southern Transitional Council to secure maritime influence around the Bab el-Mandeb strait. A unified security architecture remains entirely absent. Consequently, the rivalry between the Southern Transitional Council and Saudi-backed forces ensures that local proxy alignments remain highly fragmented, directly undermining coordinated defensive operations along the Red Sea littoral.

This fragmentation downstream degrades the efficacy of Western-led maritime initiatives, specifically Operation Prosperity Guardian, which relies on regional partners for intelligence sharing and basing rights. Without a cohesive Saudi-Emirati consensus, local partners refuse to integrate their coastal radar networks or standardise maritime patrol sectors. This persistent strategic misalignment allows Houthi forces to exploit these operational seams, ensuring that unilateral patrols by the United States Navy's Fifth Fleet remain insufficient to secure the Bab el-Mandeb.

Strategic Question for Discussion

If the United Arab Emirates continues to independently back the Southern Transitional Council, how can Operation Prosperity Guardian establish a reliable maritime intelligence-sharing network with local coastal forces?

The pattern of Gulf security cooperation suggests that without a formal Saudi-Emirati reconciliation, local forces will remain siloed and suspicious of Western-led coordination. My assessment is that Operation Prosperity Guardian will be forced to rely on ad-hoc, bilateral arrangements with individual factions rather than a comprehensive regional network. This fragmented approach ultimately limits the maritime coalition's ability to compile a real-time, unified common operational picture across the Bab el-Mandeb.
