Houthi Retaliation Highlights Eroding Deterrence of Gulf States Amid Yemen Conflict

The recent rapid Houthi response to a Saudi airstrike at Sanaa airport underscores escalating tensions between the two sides and illustrates the Houthis' strategy to establish a clear retaliatory equation against Riyadh. Within hours of the Saudi attack, the Houthis launched ballistic missiles and drones targeting southern Saudi Arabia, including the international airport in Abha. Saudi Defense Ministry spokesperson Turki al-Maliki confirmed that Saudi air defenses intercepted ballistic missile threats aimed at the country's south.

Houthi military spokesman Yahya Saree stated the missile and drone strikes were in direct response to the Saudi attack on Sanaa's airport, which the Houthis described as part of the ongoing siege against the Yemeni people. The Houthis claimed their operation achieved its objectives and warned airlines against flying over Saudi airspace until the so-called siege on Sanaa airport is lifted.

The conflict reflects the broader proxy struggle between Saudi Arabia, which supports Yemen's internationally recognized government, and the Iran-backed Houthis. Despite a partial de-escalation in 2022, no final peace agreement was reached, and regional tensions have persisted amid recent escalations. In recent weeks, the Houthis have also prepared for potential further confrontations with Saudi Arabia, including armed tribal gatherings, while simultaneously gearing up for possible clashes with Israel.

This Houthi retaliation signals a growing perception in the region that Gulf states' deterrence capabilities are weakening. Attacks on Gulf targets, once seen as likely to provoke unpredictable wide-scale escalation, are increasingly viewed as expected responses within a new pattern of conflict. Iran’s ongoing support for the Houthis, despite its own confrontations with the U.S. and other Gulf actors, reinforces the Houthis’ confidence in their regional backing.

Ultimately, the Houthis aim to establish a clear retaliatory formula: any attack on Yemeni airports will be met with strikes on Saudi airports. This approach not only serves military retaliation but also sends a broader regional message that Saudi Arabia and other Gulf states remain within the reach of Iran’s proxies, challenging the Gulf’s deterrence posture.
