What the Houthis’ entry into the Iran war means for the conflict and the wider region

Fresh Houthi attacks on Red Sea shipping would be devastating – but the Iranian proxy has reasons to be cautious

The true significance of the long-awaited entry of Yemen’s Houthis into the Iran war depends on whether the Tehran-backed proxy group is intending to send a few missiles and drones from a distance towards Israel or will instead capitalise on its proximity to the narrow Bab al-Mandab strait to effectively close off the Red Sea to shipping, just as Iran has effectively shut the strait of Hormuz.

The combined effect of both waterways being shut to commercial traffic from countries that neither the Iranians nor Houthis favour would be devastating. Napoleon Bonaparte’s remark that “the policy of a state lies in its geography” has never seemed more apt.
