A militia that used to run checkpoints in the Yemeni highlands now sits on Perim Island in the middle of the Bab el-Mandeb Strait.

That is not a local story. In two weeks in September they took Yemen’s western coast and the island that splits the strait into two shipping channels. About 10 percent of global seaborne trade still tries to squeeze through that gap. Add Iran’s grip on the Strait of Hormuz and you have something the world has not seen before: a non-state actor with a physical seat at one chokepoint and a partner sitting on the other.

This can make the Houthis. It can also break them.

Iranian officials treat the two waterways as one squeeze. As long as Hormuz stays messy, the Houthis have leverage they never had when they were just shelling Saudi border posts. They have gone from a local rebel movement to a group that can price oil, reroute tankers around Africa, and force Riyadh, Ankara and Islamabad into the same room. France is sending troops, radars and air defenses to protect Yanbu. That is how fast a coastline changes the guest list.

The paradox is already on paper. The same stretch of coast that gives them global reach also leaves them overextended and easier to hit. Hold 5,400 square kilometers of new ground and you also hold a lot of new targets.

If Hormuz stays closed or half-closed, the Houthis can try to cash the position for recognition as Yemen’s rulers. If the parties actually reopen Hormuz, the world’s remaining military and diplomatic attention swings south. Then the new islands and ports become a liability, not a crown.

I wrote about Perim the week they took it, when the story still looked like cables and Zoom calls. It is no longer that small.

If the rider falls off the horse, it is the Houthis who hit the dirt first. Not the ayatollah.

What do you think happens first: Hormuz reopens, or the Houthis get treated as a state? Tell me in the comments.
