In August, the Muslim holy city of Mecca lent its name to a mutual defense pact signed by Saudi Arabia, Türkiye, and Pakistan. Just weeks later, air-raid sirens were sounding in the same city as missiles and drones launched from Yemen allegedly approached—an interval short enough to expose the distance between the security architecture Saudi Arabia is trying to build and what it actually has.
Recent attacks on Saudi Arabia are part and parcel of a blitzkrieg launched by Ansar Allah, widely known as the Houthis, against the Saudi-backed Yemeni government in recent weeks that swept south along the country’s Red Sea coast and ended at the mouth of the Bab al Mandab Strait. The question now being asked in Riyadh is no longer simply how Yemen’s west coast fell. That is first and foremost a Yemeni question, which was wrongly answered in the immediate period by accusations of treachery and the like repeated across social media and hardened into an account that seemed to require little evidence. The broader question is who will bear the consequences of that fall—and at what cost?
Why the West Coast Collapsed
The real causes of the collapse, when gathered and set in order, need no traitor to explain them. They begin with a misreading of the scale of the Houthi build-up and a delay in acting against it. They extend to the air cover that arrived late—largely as a result of that misreading—and then halted at a decisive moment, exposing a front that had come to depend on it far more than on its own capabilities.
The problem deepens with a brittle command structure that assembled the Republican Guard forces, Tihama Forces, Giants Brigades, and Nation’s Shield under a nominally unified framework strained by mistrust and the accumulation of longstanding sensitivities. Many of these forces were poorly integrated and unevenly motivated, confronting ideologically committed and battle-hardened Houthi fighters prepared to expend themselves and making relentless use of suicide drones.
Then came the tactical details that usually decide battle outcomes. Drones struck artillery positions and their crews, causing fire cover to collapse. The command-and-control room at Jabal al-Nar sat far too close to the line of contact; the moment it fell, communications with every brigade were severed. With no alternative operations center and no plan for a tactical withdrawal, a military breach turned into a general collapse rather than an orderly retreat. Within twenty-four hours, the UN special envoy told the Security Council that the Houthis had taken Mokha, giving them a direct presence on the approaches to one of the world’s most vital maritime chokepoints.
Where the Faults Lie
Read closely, that list of causes resolves into three principal faults, all of them entirely domestic in origin.
The first is fragmented decision-making. A front composed of four components answering to four separate authorities is not, in reality, a single front; it is four fronts side by side. That is why, when the collapse came, there was no alternative command capable of regrouping the forces for an orderly withdrawal. The problem was not manpower—tens of thousands of fighters were there—but that manpower stripped of unified command becomes a human mass rather than a military force.
The second is dependence on external support. When the fate of an entire front rests on air cover decided in another capital, what has been handed over is not merely the weapon but the decision itself. This happened by the choice of the internationally recognized government, not against its will, through years of building capabilities designed to fight beneath an air umbrella and to be paralyzed the moment that protection is withdrawn.
The third is the inversion of priorities: the premature leap from building military power to manufacturing a political track, a national project, and a presidential council, before the front had been secured and stabilized militarily. This problem extends beyond the west coast to the entire anti-Houthi camp, which has too often treated legitimacy as a substitute for capability and international recognition as a replacement for control on the ground—erecting a political façade atop an incomplete security foundation.
Repricing the Defeat
The fall of the west coast, however, is not purely a Yemeni matter in its implications. Houthi control of the approaches to Bab al-Mandab inevitably gives the conflict a wider regional and international dimension.
The highest cost is structural. Riyadh’s answer to the disruption of its exports through the Strait of Hormuz has been to move more of its crude oil westward, overland by pipeline to the Red Sea. That outlet, however, still depends on a second chokepoint, now guarded by a hostile force with the capacity to disrupt passage. The threatened route and its alternative have converged into a single vulnerability, exposing Gulf energy exports at both ends simultaneously.
The cost does not stop at the Saudi shore. Egypt, which had begun to see traffic through the Suez Canal recover after an earlier crisis involving Houthi disruptions in the Red Sea, now faces renewed uncertainty at the canal’s southern approach. A waterway whose viability depends on a strait held by an armed group is not one to which shippers will readily commit, and canal revenues—a sovereign line in Egypt’s budget rather than a sectoral one—now rests partly on decisions made on the Yemeni coast.
Taken together, these developments amount to the most durable cost of all: The strait has become a pressure point that Iran can exploit at almost no expense to itself. Tehran needs no flag over Perim and no navy off Djibouti. An allied force positioned on the coast is enough to keep Gulf energy under strain at both its eastern and western gates and make the terms of any future de-escalation negotiable.
Saudi Arabia has spent the past year building security arrangements that would spare it from having to reengage directly against the Houthis, including organizing a fourteen-nation maritime coalition in July and signing the Mecca Pact in August. The latest crisis has now provided an unexpectedly early test of those arrangements, without visible intervention from any of Saudi Arabia’s new partners. The cost, in other words, is not only what the offensive took on the ground, but what it revealed about the arrangements meant to prevent it.
These developments also unfold against a wider bargaining environment. On July 23, U.S. President Donald Trump announced that the civil nuclear agreement reached earlier with Saudi Arabia was now wholly contingent on the kingdom joining the Abraham Accords—the Arab-Israeli normalization agreements first signed in 2020—a condition stated openly rather than conveyed in private. Whatever the merits of that linkage, its timing matters: Files being negotiated separately are increasingly read against one another, and a regional security setback rarely stays confined to its own column.
Widening the lens, the Houthi presence at the approaches of Bab al-Mandab casts a shadow for the international community, which appears to be searching for a way to defuse the crisis and contain the threat to maritime traffic. The UN special envoy has warned of a new and more dangerous phase whose consequences will not stop at Yemen’s borders and has called for channels of communication to remain open even amid heightened hostilities. The Security Council has likewise convened an emergency session devoted specifically to Bab al-Mandab, driven by anxiety over navigation and global trade.
The danger is that maritime de-escalation becomes an end in itself: an arrangement that puts out the fire around the strait without addressing the conflict inside Yemen, buying calm at sea by freezing the new lines of contact inland where they stand.
And that is precisely what ought to worry Yemenis rather than reassure them. The precedent of the Hodeidah agreement seven years ago offered an important lesson: a freeze in hostilities reached in order to protect a waterway can quickly solidify into a long-term status quo, leaving the party that manufactured the crisis to harvest its gains. A similar arrangement drafted today in New York under the banner of freedom of navigation could grant the Houthis practical recognition of their control of the coast, and while postponing all the issues that directly affect Yemeni lives: salaries, roads, airports, detainees, a divided economy, and a condition of no-war-no-peace that has already outlasted twelve years.
