It takes a perverse kind of logic to conclude that the US should continue to provide the weapons used to commit human rights abuses... in order to maintain influence that might theoretically be used to prevent those same human rights abuses. How's that been going so far?
The US is not leveraging this alliance for any moral good; don't fool yourself. Its for regional strategic purposes and money. Neither of which justify killing innocent people.
And the UAE/ Saudi Arabia are anti-democratic despots, lobbing their weaponry at unprotected civilians. Oh, you pick your friends, all right.
The Saudis are literally a royal family that slaughter various minorities and brutally enforce their continued totalitarian rule. There is nothing more anti-Democratic than literal monarchy.
They are both bad, The Houthis overthrow a democratically elected government in Yemen. The first video I saw of them was them ranting about the US is evil.
The slogan of the Houthi movement (officially called Ansar Allah), a political and religious movement and rebel group in Yemen, reads "Allah is Greater, Death to America, Death to Israel, Curse on the Jews, Victory to Islam" in Arabic text.
They are Yemani ISIS.
