The former Yemeni dictator, Ali Abdallah Salah was a Zaidi Shia just like the Houthis, but he was a Machiavellian Yemeni who only cared about the longevity of his leadership and aligned himself with anyone who can advance it. His survival techniques as a leader was based upon setting up complicated networks of alliances among the Yemeni clans and creating social divisions to weaken his enemies by turning them against one another. But finally, the Houthis killed him after his alliance with them came unstuck and never forgave him for his treachery.
