Why the US Warning on Saudi Airspace Signals a Wider War

The Houthis are shifting to Riyadh because they are losing in Yemen. Their offensive was meant to be a clean sweep: seize the Bab al-Mandeb, the strait at the mouth of the Red Sea, and keep going. The forces of Yemen’s internationally recognised government did not collapse as the Houthis had calculated. The Giants Brigades pushed up from the south, and government forces advanced against Houthi-held areas from the north.

On October 5, government forces said they had taken Dhubab district overlooking the strait, including its airstrip, and cut the road to the port of Mokha, The National reported. The Saudi-led coalition said 100 fighter jets were supporting the operation. The Houthis insist Mokha is still theirs. Either way, for the first time in this offensive they are losing fighters and territory, and they have decided to make Saudi Arabia pay for it.

American analysts have noticed a pattern in how they do it. The missiles and drones aimed at Saudi infrastructure carry small warheads and kill few people. They are messages more than attempts at destruction. The Houthis want one thing from Riyadh, a withdrawal from Yemen, and the message is that the strikes will keep coming every day, that a small warhead can become a large one, and that no air defence will keep them out.

That last part is a boast. Saudi Arabia has brought in air-defence support from almost every country able to offer it: Egypt, Türkiye, Pakistan, France, Britain and the United States. Saudi Arabia, Türkiye and Pakistan have already invoked their Mecca Pact over the Houthi attacks.

Gulf governments are acutely sensitive to foreign embassies describing their internal security. An American notice telling citizens to take care, to think about leaving and to expect Saudi airspace to close uses diplomatic language Riyadh resents. Saudi Arabia has not collapsed, and the situation remains under control. Issued in that form, the alert is an affront to an ally. Washington has every right to warn its citizens, but it should do so in coordination with Riyadh, not with a public statement like this.

So why issue it? Because Washington knows something. The Houthis may be preparing larger attacks. There may be intelligence that the Yemen war is about to take a sharper turn and that Saudi Arabia will not stay quiet. Or the United States may be preparing to go back to war with Iran.

The last possibility is the most dangerous, and it is now being reported. The Atlantic reported on October 7 that the White House had asked the Pentagon for options to strike Iran before the midterm elections in early November. NBC News reported the same day that the US military had drawn up new options for resuming major combat operations in Iran, with strikes before the midterms among them. That could mean action as early as the end of this month.

Donald Trump has his reasons. The cost of the war is now public. A Congressional Research Service count found that the US military has lost or damaged at least 81 aircraft in the Iran war, including 45 MQ-9 Reaper drones, 12 F-15E Strike Eagles, seven KC-135 tankers and an F-35A, Fox News reported. A single Reaper costs $30 million to $50 million, and the losses come to about $3.5 billion. Those are American figures, published in Washington, and they look bad to American voters a month before an election.

Israel, meanwhile, has been pressing claims that Iran is back at work at nuclear sites struck in the first round of the war, above all the tunnel complex beneath Pickaxe Mountain near Natanz. Satellite imagery from late June showed construction there continuing, the Foundation for Defense of Democracies noted.

This is why the airspace warning matters. If the United States returns to war with Iran, Saudi Arabia will be fighting on two fronts, and it will not be able to stay clear of the Iranian one. Whenever Saudi-backed forces gain ground in Yemen, Iran could strike the kingdom directly. It could also hit targets deep inside Saudi Arabia and say it was aiming at American assets, such as those at Prince Sultan Air Base. That would violate Saudi sovereignty under an American pretext.

Saudi airspace stayed open throughout the Iran war. The Yemen war alone is unlikely to close it. A renewed American war on Iran makes a closure a real possibility.

A closure would hit the Saudi economy hard. Tourism would stop. Saudi companies still lean heavily on foreigners: Saudization, the drive to put nationals into private-sector jobs, is relatively recent, and many chief executives, senior managers and investors are expatriates. For them, talk of closing Saudi airspace is reason enough to reconsider. The damage would be economic more than military, and American statements like this one add to it.

The timing is bad for Riyadh in another way. Saudi crude exports recovered to about 6 million barrels a day in September, roughly the 2025 average, after the US military opened a shipping lane along Oman’s coast, well away from Iran’s shore, CNBC reported. If the war resumes, Iran could try to mine that route. That would mean more pressure and more cost for Saudi Arabia and its armed forces. A new American war with Iran is against Saudi interests right now. Washington should have waited to see the outcome of the Saudi-backed operation in Yemen.

Trump’s attention, however, is on Iran. He is fixated on a country whose currency has fallen to about 2.8 million rials to the dollar and which still refuses to fold, to negotiate or to make concessions. Tehran sees Trump as a customer with a deadline. The midterms are when pressure on him works best, and once they pass, that leverage fades.

The Houthis want their strikes to force Riyadh to abandon Yemen’s government. They are getting the opposite. They are pushing Saudi Arabia toward retaliation, and the kingdom has plenty of means. Until now Saudi strikes have aimed mainly at halting the Houthi advance rather than punishing the Houthis. Saudi Arabia is reported to hold a bank of highly sensitive targets it has so far left alone, and hitting them would be a serious problem for the Houthis. As the Houthis keep escalating, Riyadh will reach for that list. Everything points to a Saudi escalation.

It should go further. Saudi Arabia must respond, and respond hard, and this is the moment for the Saudi army to go in on the ground and fight the Houthis itself. It is the one thing the Houthis truly fear: Saudi support for the government turning from air strikes, weapons and technical help into Saudi soldiers on Yemeni soil. For the Houthis it would be a disaster. The broader case for that endgame is set out in how Riyadh is preparing the Houthis’ end.

Bloomberg asked this week why the Houthis have not been beaten, and the answer starts with price. The Houthis make their own weapons, and those weapons are cheap, while the targets around them are extremely valuable. A Houthi missile costing perhaps $10,000 can hit an oil refinery worth billions. That is asymmetric war, and cheap weapons can be built in large numbers. Iran’s Revolutionary Guards passed the Houthis the know-how for factories dug under mountains, the same model they use against the Americans.

The ground war is unsettled too. The Houthis claim they have entered Taiz and post videos of fighters in government areas taking down pictures of the government’s leader. Those claims are unproven. Al Arabiya, which at times slides into war propaganda, has repeatedly undercut them by broadcasting from inside Taiz and from areas near the Bab al-Mandeb that the Houthis say they hold. Its reporters describe heavy fighting on the Hayfan front, where the Giants Brigades have taken commanding heights.

This war will be long. It will not end today, tomorrow or next week, and its goals may take months to reach. Government forces are already talking about an operation into Sanaa.

The Saudis will see this through and will not bow to Houthi pressure. They have absorbed heavy losses rather than make the concessions that would have spared them, and that deserves praise, not criticism. Nobody should be asking why Saudi Arabia lets Houthi missiles through. It has brought in every air defence available, Egyptian systems included.

Saudi steadfastness drives the Houthis mad, just as Iran’s endurance drives Trump mad. The Houthis won sympathy across the region when they fought Israel. Now they are firing on the country of Mecca and Medina, an act of pure recklessness that has cost them whatever sympathy they had left. Their real target was always Saudi Arabia; the war with Israel was a show.

The region should stand with Saudi Arabia. Washington, for its part, should understand what its own warning implies: a return to war with Iran would be a catastrophe for the whole Middle East, and the Yemen war would feel it first.
