So the Houthis fire a lot of drones at ships in the Red Sea. The Americans and Brits shoot down virtually every single one of them. I thought obviously the Houthis aren't very capable, and America and the UK are very capable, and the Houthis probably need to come up with another tactic.

But then I learned that Houthi drones cost $2,000 while the American missiles that shoot them down cost $2,100,000. So even when the drones don't hit anything, the Houthis achieve something of great worth: wasting an expensive American missile.
