Last month, Iran-aligned Yemeni rebels advanced along Yemen’s coast and threatened to shut down Saudi Arabia’s Red Sea shipping lanes, yet the Trump administration declined to intervene out of concern for starting a new front in its conflict with Iran.
Saudi Arabia Supercharges Military Diplomacy
Following the U.S. rebuff, Saudi Arabia has pursued new regional alliances to secure its borders and trade corridors. In July, the kingdom announced a 15-nation maritime alliance designed to safeguard shipping traffic through the Red Sea, the Bab al Mandab strait, and the Gulf of Aden. Soon after, Riyadh established the Mecca Joint Defense Agreement, a NATO-inspired security pact specifying that any attack on Saudi Arabia, Turkey, or Pakistan will be treated as an assault on all three members.
Relations with regional neighbors have also shifted as part of this diplomatic push. Saudi Crown Prince Mohammed bin Salman and his defense minister brother hosted the United Arab Emirates’ vice president this week for the first high-level meeting since the two countries fell out over Yemen late last year. Reports have even indicated potential cooperation between Saudi Arabia and Israel against the Houthis, though the two nations maintain no formal diplomatic ties.
Economic Fallout From Infrastructure Attacks
These diplomatic moves arrive as the kingdom grapples with severe economic pressure stemming from regional hostilities. Standoffs over the Strait of Hormuz have choked off the nation’s primary export route, while ongoing assaults on energy infrastructure have suppressed oil output. Official economic data shows a 25 percent contraction in oil activities, which drove a nearly 5 percent decrease in gross domestic product between April and June compared with the first quarter of the year.
This financial contraction forced significant cutbacks to Vision 2030, the crown prince’s signature policy. High-profile development initiatives, including the Line and Trojena, have scaled back their ambitions in response to budget constraints. The economic strain intensified as the conflict with Houthi forces escalated across the southern border and vital transit zones.
Escalating Conflict With Houthi Rebels
The military confrontation escalated significantly after Saudi forces attacked the airport in the Yemeni capital of Sanaa in July to block an Iranian plane carrying high-ranking Houthi officials. That strike triggered retaliatory Houthi attacks on Saudi infrastructure and a declared blockade against Saudi shipping in the Red Sea. In September, Houthi fighters overran Yemeni coastal cities, captured military equipment left behind by Saudi-backed government forces, and seized territory near the Bab al Mandab strait.
Shortly after those territorial gains, Saudi officials accused an Iranian-backed militia in Iraq of coordinating with the Houthis to strike the East-West Pipeline, the critical corridor allowing the kingdom to reroute oil away from Hormuz. Seeking assistance, the crown prince turned to Washington, pointing to a strategic defense agreement signed late last year that designated Saudi Arabia a major non-NATO ally and cleared the sale of advanced F-35 fighter jets. Prince Mohammed also maintained a personal relationship with President Trump, who visited Riyadh as the first stop of his first overseas tour in 2025 after being reelected and highlighted nearly $1 trillion in Saudi investments into the U.S. economy. While President Trump initially appeared receptive to the request for help, he reportedly pulled back just as U.S. warplanes prepared to launch strikes against Houthi targets.
Unresolved Defense Commitments in the Region
With Washington withholding direct military intervention against the Houthi advance, it remains unclear whether Saudi Arabia’s newly formed coalitions can effectively secure its energy infrastructure or reopen its vital Red Sea shipping lanes without American backing.
