saudi arabia risks two-front economic exposure after reopening yemen war
houthi threats to saudi airspace and shipping put the oil-export and aviation ambitions of vision 2030 back in the firing line.
On July 13th the runway at Sanaa airport was cratered to stop a Mahan Air flight from Tehran. The plane diverted to Hodeidah on the Red Sea coast and landed there anyway. It was carrying a returning Ansarallah (better known as the Houthis) delegation with patients and stranded Yemenis. Ten days earlier the first Iranian plane to reach Sanaa in a decade had landed at the capital directly, after according to Ansarallah, Saudi jets chased it and backed off when their air defenses threatened to fire. Two attempts to close the sky, two landings. But the failed intercept is the small story. The large one is that Saudi Arabia chose to reopen a war against an enemy with nothing to lose, at the exact moment the kingdom itself has everything to lose.
who made the call?
Aden’s defense ministry publicly claimed the operation, saying the runway was struck to prevent the Iranian aircraft from landing, while Riyadh issued no acknowledgment of its own role. But Axios, citing two U.S. officials, reported that it was the Saudi military that bombed Sanaa airport. The same officials said Mohammed bin Salman had asked Donald Trump for American backing beforehand and received it. The White House did not directly confirm that account and the Saudi Embassy has not responded to journalists.
That silence is politically useful. Since restoring relations with Iran through Chinese mediation in 2023, Riyadh has tried to preserve the détente that helped freeze its Yemen front. Publicly admitting that Saudi jets struck an airport to prevent an Iranian airliner from landing would mean owning the precise escalation the kingdom has spent four years trying to avoid.
Now look at the other side. Ansarallah have little peace left to protect. War has been their normal condition for more than a decade. Since the Saudi-led intervention began in 2015, Yemen has endured years of air strikes, import restrictions and institutional collapse, producing what the United Nations has repeatedly called one of the world’s worst humanitarian crises. At the height of the crisis, most of the country required some form of humanitarian assistance.
The campaign was sustained by American weapons, logistics, advice and intelligence. Until November 2018, the United States also refueled coalition warplanes in flight, allowing them to remain over Yemen longer. Washington ended that refueling role, but not the wider military relationship.
Ansarallah have since fought the United States more directly. American and British forces repeatedly struck Ansarallah-controlled Yemen throughout 2024. Beginning in March last year, the Trump administration launched an intensified seven-week campaign that hit more than a thousand targets. It ended not with the movement’s destruction, but with an Oman-brokered agreement under which Washington stopped bombing and Ansarallah stopped targeting American vessels.
They have exchanged direct fire with Israel as well. An Ansarallah drone reached Tel Aviv in July 2024 and killed one person, while their missiles have repeatedly triggered alarms across central Israel. Israel answered with strikes on Yemen throughout 2024 and 2025.
A movement that has survived all of that has few soft and expensive assets left to hold hostage. Being attacked can even serve it politically. The Saudi border was the one major front Ansarallah had kept comparatively quiet since the 2022 truce. By striking Sanaa airport, Riyadh gave them a reason to reopen it. Large crowds gathered in al-Sabeen Square after the attack, condemning Saudi Arabia and backing the Ansarallah response. That is the political return on Riyadh’s strike: another demonstration of the movement’s ability to turn external attack into internal mobilization. You cannot easily deter a force whose baseline is war and whose legitimacy is reinforced whenever a foreign power bombs it.
Saudi Arabia is the opposite kind of target. Everything MBS is building depends on calm. everything from Vision 2030, the 2034 World Cup, to the foreign capital he is courting makes the kingdom’s exposure no longer only economic but physical, and within Ansarallah range. The East-West Pipeline was built across the peninsula in the 1980s to move crude from the eastern fields to Yanbu on the Red Sea, so that exports would not depend on tankers clearing the Strait of Hormuz. The Houthis have demonstrated they can reach it before, hitting pumping stations in 2019 and the YASREF refinery at Yanbu in 2022. Right now, that backup route has become the kingdom's most important one. As the war on Iran halts Gulf shipping on the Strait of Hormuz, Saudi Aramco increased reliance on the East-West Pipeline. The line was built precisely to give Saudi Arabia an alternative to Hormuz, but it also concentrates a larger share of the kingdom's exports on the Red Sea coast and within reach of Ansarallah missiles and drones. Ansarallah have already signaled they view those assets as legitimate targets. On July 4th (after accusing Saudi Arabia of trying to block the Iranian civilian flight from reaching Sanaa) they warned that any further Saudi action would put the kingdom's airports and other vital interests on land and at sea in their crosshairs.
The risk for Saudi Arabia is not only aerial, because back during the active war Ansarallah have pushed across the border into the southern provinces of Najran, Jazan and Asir, overrunning outposts on the ground with anti-tank and MANPADS teams. (These Southern Saudi regions are regions Yemen lost to Saudi Arabia in the 1934 war and they spent the time since treating the Treaty of Taif that ceded them as an imposition. In 1966 its government declared the treaty void and vowed to recover the provinces by force as historically Yemeni land. Ansarallah rose out of Saada which is directly on that border. You can kind of say this is the one front where they fight as a movement reclaiming what it calls occupied territory. That is something airpower alone cannot stop, and a front Riyadh cannot hand to a proxy to fight for it.)
Saudi Arabia is exposed on the water too. The East-West Pipeline only solves the Hormuz problem if the Red Sea remains open. That sea narrows at Bab al-Mandeb, the chokepoint where Ansarallah attacks have disrupted shipping since late 2023 and forced many vessels onto the far longer route around the Cape of Good Hope. The campaign effectively strangled Israel's only Red Sea outlet at Eilat, where activity collapsed by more than 85 percent before the port slid into financial crisis and eventual shutdown. Reopening the Yemen front creates the risk that the same pressure could be turned against Saudi-linked shipping. If Bab al-Mandeb becomes hostile to Saudi cargo as well, the kingdom would find itself squeezed between two maritime chokepoints at once. Saudi Arabia spent decades and billions of dollars building a way around one. A renewed war in Yemen could make the second one the more dangerous of the two.
None of that exposure was live while the truce held. Riyadh reopened all of it for a single plane, breaking the ceasefire that had stood since March 2022. Ansarallah answered within hours by launching ballistic missiles and drones on Abha International Airport and a warning to every airline to stay out of Saudi airspace until the siege of Sanaa is lifted. Saudi Arabia answered that by bombing Saada, Ansarallah heartland. These were the first Ansarallah strikes on Saudi soil in three years, and every rung of that ladder is climbed by the side with everything to lose.
The airline warning works the same way as the shipping threat. Ansarallah only have to keep putting missiles and drones onto airports, as they did at Abha, and the cancellations follow. Airlines have already cancelled flights serving Abha. The Houthis are also making it clear that they do not see the fight ending at Abha. In footage released by them, they highlighted major Saudi airports including Riyadh, Jeddah and Dammam. Saudi Arabia is trying to become the region's aviation and tourism hub. It even just launched a new airline, Riyadh Air. Coupled with the giant construction projects and the 2034 World Cup, it all depends on safe skies. Once airlines and passengers begin treating Saudi airspace as a potential battlefield, the war has reached the exact thing Vision 2030 is built on.
So in the end, to stop a single Iranian plane, Saudi Arabia broke a four-year calm and put its own airports, ports, oil infrastructure and shipping lanes back within range. The plane landed in Hodeidah anyway, the delegation walking off on camera the same day. the whole move prevented nothing and changed nothing. What it did accomplish was reopening a conflict that had largely been frozen since 2022. For Riyadh, that is a remarkably high price to pay for so little.
