Saudi Arabia left alone as Trump prioritizes US interests over Yemen conflict

In May 2025, President Trump stood before cameras and declared the Houthi threat finished. The Iran-backed militant group, he said, had capitulated. They had agreed to stop attacking ships in the Red Sea. The United States, having conducted weeks of bombardment on Houthi targets across Yemen, would now extract itself from the conflict. It was framed as a victory—an early win for the "America First" doctrine that would define his second term. What it actually represented was a withdrawal, not a resolution. The Houthis had not been militarily defeated. They had simply agreed to pause their maritime attacks. They remained free to continue fighting Israel, which had been excluded from the agreement entirely. When Trump flew to Saudi Arabia a week later for his first major international trip, observers noted the obvious: Israel had been abandoned to face the threat alone.

Over a year later, Saudi Arabia discovered it had been abandoned too. The informal ceasefire that had held since 2022 collapsed in recent weeks as fighting reignited along the kingdom's southern border. Houthi attacks struck at Riyadh and Mecca. They targeted the East-West oil pipeline and facilities at Yanbu port. They declared a blockade on Saudi-linked vessels transiting the Red Sea and began striking Saudi ships directly. The group, backed by Iran and armed with increasingly sophisticated weaponry, had returned to active operations with renewed intensity.

For Saudi Arabia, the timing could not have been worse. A separate conflict—the ongoing US war with Iran—had already squeezed the kingdom's economy. Iran's blockade of the Strait of Hormuz had restricted Saudi oil exports. In response, Riyadh had begun routing some shipments through the Red Sea, using a bypass route that now faced direct threat from the very group the United States had supposedly neutralized. The kingdom found itself caught between a deteriorating security situation and economic pressure it could not absorb alone.

Saudi Crown Prince Mohammed bin Salman, the kingdom's de facto ruler, called Trump twice in September requesting military backing. The response was thin. Trump offered intelligence sharing and targeting data. He refused new US military operations, insisting the agreement with the Houthis remained in force. For a country that had just been designated a major non-NATO ally and had committed to investing $1 trillion in the US economy, the rebuff stung. One observer captured the moment plainly: Riyadh's bet on Trumpism had failed.

The American reluctance to recommit forces to Yemen reflected a broader constraint. Seven months into a war with Iran that was supposed to last weeks, the United States remained bogged down. What had begun as a campaign for regime change had narrowed into a grinding effort to secure the Strait of Hormuz against a new, more hardline Iranian leadership. The White House faced mounting political and public criticism over the war's costs as midterm elections approached. Yemen was simply not a priority.

This was not a new problem, merely an exposed one. When the Houthis first began attacking maritime targets in the Red Sea following the October 2023 Hamas attacks on Israel, the group revealed itself to be far more capable than its reputation suggested. These were not ragtag insurgents. They were disciplined operators who understood asymmetric warfare. Using low-cost drones, they cut Suez Canal traffic by half in 2024. Operation Prosperity Guardian, the US-led maritime coalition launched in December 2023 to secure Red Sea passage, struggled to counter them. Shipping companies simply rerouted around Africa via the Cape of Good Hope, accepting higher insurance premiums rather than risk Houthi attack. Even months after the group ceased their strikes, traffic remained 60 percent below mid-2023 levels.

US air campaigns against the Houthis had produced limited results. By the time Trump declared victory, the group had moved critical assets underground into bunkers while continuing to launch low-cost drones and missiles at shipping. The United States, meanwhile, had burned through precision munitions at a rate that alarmed military planners worried about stockpiles and readiness in the Indo-Pacific. The Houthis had mastered a tactic that exposed American vulnerabilities: combining accurate weapons with low-cost, scalable systems—a mismatch for the limited, expensive interceptor systems available to the US and its regional partners.

Saudi Arabia has begun hedging its bets. France announced the deployment of troops and radar systems to protect Yanbu operations and limit energy price spikes. The UK pledged defensive support focused on refueling Saudi aircraft. Most significantly, Riyadh's recently signed military pact with Pakistan and Turkey faced its first real test. The agreement has not yet produced a coherent operational response, but Washington's recent stance will likely only deepen its importance. For Saudi Arabia, the era of relying on American military commitment appears to be ending. What comes next remains uncertain.
