Why Washington Is Resisting Riyadh’s Call to Strike the Houthis

WASHINGTON — Saudi Arabia is facing what regional security experts describe as an unprecedented threat to its oil export infrastructure, with Houthi territorial gains near the Bab el-Mandeb Strait and cross-border attacks targeting the kingdom’s domestic energy networks.

The threat intensified on Sept. 11, 2026, when a drone launched from Iraq targeted Saudi Arabia’s critical East-West pipeline and forced a temporary shutdown of the cross-country line. Satellite imagery captured on Sept. 13, 2026, confirmed physical damage to the infrastructure.

The pipeline, also known as the Petroline, spans approximately 745 miles from the Eastern Province to the Red Sea port of Yanbu. It is designed to transport up to 5 million barrels of crude oil per day while bypassing the volatile Strait of Hormuz. President Donald Trump later stated he believed Iran was behind the drone attack.

Saudi Arabia’s vulnerability has also shaped appeals from Riyadh. According to a source familiar with the discussions, Crown Prince Mohammed bin Salman directly urged Trump to launch military strikes against the Houthis to halt their advances. The crown prince’s appeal came as the kingdom’s alternative oil export routes faced a direct threat.

During a visit to Ireland, Trump revealed that the Houthis had initiated contact with the U.S. government. He said the rebel group wanted to avoid a direct military confrontation, did not want to fight the U.S., and preferred that Washington remain uninvolved in the ongoing conflict.

Days after the pipeline strike, Saudi air defense forces intercepted and destroyed a Houthi-launched drone near the city of Mecca. The incident followed the Sept. 11 attack and added to the threats facing the kingdom from multiple directions.

The geography of Saudi Arabia’s oil shipping is central to the crisis. Historically, most Saudi oil exports have traveled through the Strait of Hormuz, a narrow waterway between Oman and Iran through which roughly a fifth of the world’s petroleum passes. Stringent U.S. economic sanctions and blockades on Iranian oil exports have severely restricted Tehran’s ability to sell its crude.

According to Hussain Abdul-Hussain, a research fellow at the Foundation for Defense of Democracies, Iran responded by attempting to enforce an “all or none” rule for regional oil exports and threatening to disrupt traffic through Hormuz. Saudi Arabia subsequently shifted a significant portion of its export volume westward, sending crude through the East-West pipeline to Yanbu.

From Yanbu, tankers sail south through the Red Sea and the Bab el-Mandeb Strait toward Asian and European markets. In response to the diversion, Iran likely prompted the Houthis to establish a de facto blockade at the Bab el-Mandeb Strait, an 18-mile-wide maritime chokepoint flanked by Yemen, Djibouti, and Eritrea.

“This is the biggest threat to their production of oil since their kingdom was founded in 1932,” Abdul-Hussain said, characterizing the situation for Saudi Arabia as nearly existential.

The diplomatic division between Washington and Riyadh has emerged over maritime security in the Red Sea. The United States remains hesitant to commit military assets or intervene directly against Iran-backed Houthi forces despite urgent appeals from Mohammed bin Salman.

The Houthis have calibrated their campaign by announcing that they are exclusively targeting Saudi vessels and maritime infrastructure rather than broader international, European, or U.S. shipping. That selective targeting presents a policy challenge for the U.S. administration.

“Our expectation as Washington is that the Saudis, with all these arms that we’ve sold them over the past few decades, with all the military support and advice we give them, that they should be able to protect their own tankers and ships in this waterway and keep it open,” Abdul-Hussain noted, adding that Riyadh has struggled to independently contain the non-state actor.

For decades, Saudi Arabia has been the largest recipient of U.S. defense exports, purchasing Patriot missile defense batteries, F-15 fighter jets, and precision-guided munitions. Houthi forces continue to make tactical gains on the ground and in the maritime domain despite those acquisitions.

On Sept. 12, 2026, Houthi forces paraded in the capital of Sanaa as Yemeni prisoners loyal to the group arrived following their release from the west coast, where Saudi-backed Yemeni government forces had held them.

A senior U.S. administration official stated that Washington’s policy remains centered on defending core national security interests, such as general freedom of navigation in the Red Sea, while encouraging regional partners to take the lead in resolving localized security challenges. The administration maintains continuous communication with both Saudi Arabia and Yemeni representatives regarding regional stability.

The Saudi Embassy in Washington, D.C., did not immediately respond to requests for comment on the ongoing security situation and the diplomatic discussions.
