Houthi Resilience Tests MECCA’s Defence Credibility and Saudi Arabia’s Strategy
STRATEGIC QUESTION
How are escalating Houthi attacks against Saudi Arabia testing the deterrent credibility of the MECCA defence agreement?
KEY JUDGEMENTS
The Houthi attacks against Saudi Arabia continue to test the strength of the MECCA agreement following the partners' 5 October joint statement. Reaffirming mutual defence has yet to translate into effective deterrence, raising questions about the agreement's credibility.
The Houthis have demonstrated operational resilience and military capacity, launching long-range strikes while under increasing pressure in the district of Dhubab. Houthi territorial losses have not eliminated the drone and missile threat to the Kingdom, while previous airstrikes have also struggled to significantly degrade Houthi strike capabilities.
Saudi Arabia faces a strategic dilemma between strengthening its air defences and intensifying military operations, which could risk further escalation and draw in MECCA partners. Low interceptor stockpiles have prompted the Kingdom to request external assistance, which may accelerate the operationalisation of defence cooperation with MECCA partners.
BACKGROUND
The Houthis launched a series of attacks targeting Saudi Arabia’s international airport in Riyadh over the weekend. The airport was struck by projectiles four times in five days, reportedly killing 13 people and injuring 300 others. The attacks follow a Saudi-backed counteroffensive by the Yemeni government against Houthi rebels in the district of Dhubab near Bab el-Mandeb.
The Houthi escalation against Saudi Arabia follows a 5 October joint statement by MECCA partners reaffirming their collective defence commitment and determination to defend Saudi territory.
STRATEGIC ASSESSMENT
Despite the release of the MECCA partners' 5 October joint statement, strikes against Saudi infrastructure escalated. Although the partners reaffirmed their defence commitments, these have not yet deterred further Houthi attacks, possibly because the partners have yet to fully operationalise and coordinate their military capabilities. The rapid Houthi attacks may indicate the rebels are responding to the counteroffensive before the partners deepen their military cooperation while also testing the credibility of the joint statement. This also suggests that significant military partners, including a NATO member and a nuclear power, do not necessarily provide immediate deterrence against a mobile non-state armed group, particularly without established operational readiness and interoperability. The Houthis may also be difficult to target using conventional military capabilities.
Simultaneously, the Houthis have demonstrated the ability to conduct long-range strikes despite a counteroffensive, suggesting operational resilience. Although the Yemeni government forces supported by Saudi airpower have made territorial gains, these have not eliminated the Houthi long-range threat, suggesting the Houthis are still able to coordinate and benefit from their dispersed military capabilities. Despite reported Saudi fighter involvement, Houthi resilience suggests that conventional military operations may have limitations in reducing the threat. Over the past decade, the Houthis have developed their military expertise and organsiation, expanded their arsenal of ballistic and cruise missiles with Iranian support, and potentially developed domestic drone manufacturing capabilities. Previous U.S. and U.K. airstrikes largely failed to degrade Houthi capabilities, suggesting MECCA partners could face similar challenges.
The Houthis have indicated that they will continue to attack Saudi Arabia, excluding the religious sites, leaving the Kingdom facing strategic decisions. Saudi Arabia may intensify operations in Yemen, although airstrikes against the Houthis may have limited effectiveness in reducing their military capabilities. Saudi Arabia may also strengthen its air defences, reportedly seeking assistance from France, Britain, Egypt and Pakistan. Following the MECCA joint statement, Saudi Arabia may seek to accelerate operationalisation through air defence deployments, logistical support, intelligence sharing and improved interoperability. Although the statement reaffirmed the partners' commitments, their response to the Houthi attacks may either expose limitations in the defence pact or demonstrate deeper military cooperation through a coordinated defensive response.
WHAT TO WATCH
MECCA operationalisation with evidence of deployments, air defences, technical personnel, intelligence sharing and logistical transfers.
Saudi military responses, including increased strikes against Houthi targets in Yemen, alongside responses from France, Britain, Egypt and Pakistan to requests for air defence support around critical infrastructure.
Houthi drone and missile strike frequency against Saudi targets, which may extend beyond airports in efforts to maintain pressure on the Kingdom.
U.S. diplomatic support for Saudi Arabia, including potential intelligence sharing and targeting assistance.
