A plan for the Houthis

Apparently having figured out that launching rockets tended to get them shot down, Houthi terrorists have started to attack shipping as classic pirates.  Now the fine people at Powerline suggest hanging them from the yardarm, which is a good idea, but the thought that occurs to me is that the civilized nations of the world ought to provide ships with "transit crews" which would have a simple rule; if your boat is loaded with masked men with Kalishnikovs, and comes within a mile of a merchant ship, you will become acquainted with Ma Deuce.  Hope you can swim, boys.
