Bullshit. The "government" of Yemen, backed by the House of Saud, harbored Al Qaeda terrorists (also backed by the House of Saud). The Houthis, a home grown resistance movement, now backed by Iran, overthrew the terrorist-harboring, Saudi backed government. The Sauds then launched their genocidal war against the Houthis and anyone else who happens to live in Yemen. So we have the U.S. once again backing the very people who attack us. Even Congress couldn't stomach the stupidity of our policy and told Trump to stop supporting the Sauds' dirty little war.
Also, LOL at the idea of a Saudi-backed pro-western government.
