Saudi Arabia has come under attack on two fronts in the past week.
In Yemen, the Houthis seized the port city of Mocha on September 10 and advanced along the Red Sea coast toward the Bab el-Mandeb Strait, a vital waterway for Saudi exports. Meanwhile, drones from Iraq struck Saudi Arabia’s East-West Pipeline, the roughly 750-mile artery that carries oil from the eastern fields toward Red Sea export terminals.
Those attacks landed as the Iraqi government’s September 30 deadline for nonstate groups to disarm approaches, and as U.S. and Israeli pressure mounts on Iran, which arms and sustains the Houthis. The broader campaign against Tehran’s regional proxy system has already put the Islamic Republic under severe military and financial strain, according to the record in front of us. Since the U.S. war with Iran began on February 28, Operations Epic Fury and Economic Fury have targeted Iranian oil exports, shadow-fleet tankers, financial intermediaries, and foreign procurement networks.
Yet the pressure has not dissuaded the Houthis. For months, the Islamist militia based in northern Yemen has terrorized commercial and military vessels in the Red Sea and the Bab el-Mandeb Strait. International forces, including the United States, have failed to stop them despite an extraordinary disparity in conventional military power.
That is the central fact here: a militia that looks ragtag on paper has been able to keep punching far above its weight, while Saudi Arabia finds itself under attack, rebuffed in its requests for U.S. aid, and caught in the middle of a U.S.-Iran war now in its seventh month. The obvious question is not whether the Houthis have become dangerous. They already have. The question is what happens if the pressure on Iran begins to bite hard enough to threaten the network that keeps them supplied, directed, and in the fight.
Mohammed bin Salman’s Monday meeting with the head of U.S. Central Command underscores the stakes. The kingdom is not dealing with a single raid or a one-off provocation. It is dealing with a regional order in which the costs of tolerating armed proxies are borne by shipping lanes, pipelines, and taxpayers who end up underwriting endless crisis management.
Follow the incentive, not the press release. If Iran’s reach is weakened, the proxy architecture that has shielded the Houthis may finally become less durable. If it is not, the burden falls again on the same states and sea lanes, and the region learns the same lesson it has learned too many times already: weakness invites more aggression, and ambiguity invites more war.
