The Rise and Complexities of the Houthi Movement

The Red Sea is the most trafficked trade route in the world, and now the US Navy and a group of militant Houthi rebels are going to war over it.

The Houthis are attacking ships it says are linked to Israel and its allies; America is desperately trying to stop them. I mean, America might not get directly involved in the Israel-Gaza conflict, but you bet they'll protect their trade routes.

The stakes couldn't be higher — if the US can't prove they have this under control, plenty of other groups around the world might decide to try their hand at blocking global trade as well.

Editor's note: This introduction has been edited to clarify that not only Israeli ships have been targeted in Houthi attacks.
