Saudi Arabia’s Reliance on Defence Partners Risks Widening the Yemen Conflict
STRATEGIC QUESTION
Is Saudi Arabia's growing reliance on external military assistance increasing the risk of a wider conflict in Yemen?
KEY JUDGEMENTS
The Houthis’ continued long-range attacks and territorial operations may expose the limits of Saudi Arabia’s military response and increase its dependence on external defence partners.
External defence support provided to Saudi Arabia may allow the Kingdom to conduct offensive operations in Yemen even without partners participating in offensive action.
The Houthis may respond to external defence assistance with renewed attacks against commercial shipping, expanding the conflict in attempts to deter further partner involvement.
BACKGROUND
The conflict between the Houthis and Saudi Arabia continues to escalate following a series of attacks and counterattacks. The Houthis’ rapid advance into the district of Dhubab followed earlier strikes against Saudi energy infrastructure with the rebel group seeking to strengthen its position along the Bab el-Mandeb. A counteroffensive launched by Yemeni government forces, supported by Saudi airpower, recaptured territory in Dhubab. Despite MECCA partners releasing a joint statement on 5 October reaffirming support to defend Saudi territory, neither the Saudi-backed counteroffensive nor the joint statement has deterred Houthi attacks which targeted Riyadh airport. On 13 October, Aramco headquarters was reportedly struck amid continuing Houthi attacks against Saudi critical infrastructure.
Several partners have contributed to Saudi Arabia’s defence, including France with radar systems, defence systems, and soldiers, Britain with an RAF Voyager aircraft, and MECCA partners providing military capabilities.
STRATEGIC ASSESSMENT
Houthi attacks against Saudi Arabia have continued to target critical infrastructure following the counteroffensive in Dhubab. Despite Houthi forces facing a counteroffensive, the Houthis’ ability to maintain long-range attacks over the last week against Saudi targets demonstrates the group’s capabilities and operational resilience. The Houthi attacks against Saudi critical infrastructure may suggest the group intends to increase military and economic pressure as part of a dual strategy to constrain Saudi Arabia’s intervention in Yemen. Saudi Arabia’s strategic dilemma is having to increase its domestic air defences around critical infrastructure while considering increasing offensive operations in Yemen against a mobile and resilient Houthi group that has yet to be deterred by Saudi Arabia and its allies.
Saudi Arabia’s requests to defence partners for assistance may strengthen the Kingdom’s defence and allow reallocation of its resources to Yemen. Although defence partners France, Britain and MECCA partners have agreed to Saudi Arabia’s requests, the military capabilities provided have largely focused on defensive support. Despite spending hundreds of billions of dollars on defence, the Kingdom remains exposed to Houthi attacks from drones and Iranian-designed missiles that can alter trajectory and fly at low altitudes, highlighting the asymmetry between the two sides. Low-cost and rapidly produced drones also require Saudi Arabia to expend interceptors, which creates a further asymmetry due to the disparity in production rates, with interceptor stocks reportedly low. Saudi Arabia’s defence partners have distinguished between assisting with defensive and enabling offensive measures, with France in particular contributing to the protection of the Yanbu oil terminal. However, greater domestic protection provided by defence partners may also allow Saudi Arabia to shift its focus towards offensive measures against the Houthis.
Greater external support for Saudi Arabia may lead to intensified operations in Yemen and risk further escalation. With reports of Saudi Arabia striking Houthi targets including a petroleum facility, fuel storage tanks and oil infrastructure, alongside strikes against Houthi positions in Taiz on 13-14 October, the Kingdom’s rapid offensive response coincides with seeking external support to strengthen its defences, which may also indicate that Saudi Arabia anticipates further Houthi retaliatory attacks. Involvement from external partners may draw a response from the Houthis with potential threats or attacks against commercial shipping, increasing the risk of disruption in Bab el-Mandeb. Any attacks on commercial shipping may discourage France, Britain and MECCA partners from further military involvement, or alternatively contribute to escalating the conflict. Defence partners will need to balance providing assistance with the risks of further disruption to commercial shipping and escalation of the conflict.
