For those interested, check out the latest Frontline episode on Yemen. The director was also interviewed on Tuesday's (7 April) Democracy Now.
The situation in Yemen is a confusing mess but she does a decent job outlining what's happening. A lot more could be said, but it's PBS and they're only going to go so far in criticizing the American role in all of this.
If you're looking to get a basic understanding of the situation without having to do a bunch of reading, watching this documentary will go a long way.
