A missile strike on Riyadh's international airport on Saturday killed 13 people and wounded over 300. A second attack on Sunday killed one more and injured 11. The Houthis simultaneously hit Dammam's airport and two oil facilities. Saudi Energy Minister Prince Abdulaziz bin Salman warned of consequences for energy security. These are not new threats — they are the same threats that have defined this conflict since 2015, now delivered with greater precision and frequency. The Saudi military response follows its established playbook: airstrikes on launch pads and storage facilities. Saudi military spokesman Turki al-Maliki claims 136 military targets destroyed. But the American Enterprise Institute report framing these numbers also implicitly acknowledges the core problem: Saudi Arabia has been destroying Houthi infrastructure for a decade without degrading the militia's operational capacity. The Houthis control large parts of northern Yemen and increasingly the western coastline, from which they disrupt Red Sea shipping through the Bab el-Mandeb Strait. In early September, drones severely damaged the Saudi East-West oil pipeline, temporarily disrupting oil exports. Riyadh is now engaged in frantic coalition-building. The UK pledged aerial refueling for Saudi fighter jets; France offered troops, radar systems, and air defense technology to protect the Yanbu oil terminal. Pakistan, which signed the Mecca Joint Defense Agreement in August alongside Saudi Arabia and Turkey, is reportedly conducting airstrikes on Houthi positions — though Islamabad officially denies this. Turkey is providing air defense equipment but rules out offensive operations. The UAE's senior diplomatic advisor Anwar Gargash called for revitalized Gulf security cooperation, noting that "we are all targets." The United States has so far refused to fight alongside Saudi Arabia against the Houthis, though political analyst Osamah Al-Rawhani of the Sanaa Center for Strategic Studies suggests Washington may be reconsidering. He cautions that holding captured territory and sustaining counterattacks require financial resources, political commitment, and resolve that Saudi Arabia may not be able to muster. His assessment is blunt: "If the costs of the war continue to rise, Riyadh might look for a way to withdraw from the conflict." Marcus Schneider of the Friedrich Ebert Foundation's Center of Expertise on Peace and Security identifies the structural impossibility at the heart of Saudi strategy. Eliminating the Houthis would require ground troops, but Riyadh has no experience with ground warfare in a foreign country. The Houthis are well-entrenched and can absorb significant punishment. The asymmetry is fundamental: Saudi Arabia possesses modern weapons and spends enormous sums on defense, but the Houthis do not need to win conventionally. Missiles, drones, infrastructure threats, and shipping disruption are sufficient to achieve their strategic objectives. This asymmetry directly threatens Vision 2030, Crown Prince Mohammed bin Salman's economic diversification program that requires stability, foreign investment confidence, and functioning energy infrastructure. Every airport closure, pipeline hit, and shipping disruption erodes the investment thesis that underpins the entire reform agenda. The Soufan Center's analysis confirms that whether the new coalition produces results depends on partners moving beyond limited airstrikes and political solidarity — and on the fragmented Yemeni government forces achieving better military coordination, neither of which has materialized. Iran's offer to mediate between Riyadh and the Houthis completes the strategic bind. Tehran arms and supports the Houthis while offering to broker peace, a position that gives Iran leverage regardless of the outcome. With Iran and the US already in direct conflict and Saudi Arabia aligned with Washington, any mediation framework that requires Iranian good faith is structurally compromised. The war continues because the Houthis have no incentive to stop and Saudi Arabia has no viable mechanism to make them.
