Al-Bukhaiti does not think that ‘the Iranian system’ [a Shia theocracy] could ever be implemented in the country. Neither do the Houthis have any interest in bringing back the Imamate. Instead, he describes the Zaydi [their Shia] doctrine as ‘republican’ and the Houthi group as ‘liberal’.”
That's what I was taught about the Houthi of Yemen. The US is at war against republican liberals, and the US allies in that war are medieval monarchies and fascists.
