But just as in Syria, the U.S. finds itself committed to the downfall of a Shia government, while at the same time working to degrade the ability of al Qaeda to benefit from the fall of that same government. The Saudi coalition routinely bomb civilian targets like hospitals or food production facilities. In turn, the Houthis have resorted to extreme tactics as well.
It’s just the sort of messy intervention that an establishment hawk like Hillary Clinton would’ve hubristically prosecuted and that populists are understandably tired of financing. (Some hawks regard it as a proxy war against Iran, a view many dispute.)
