The Houthis, a Zaidi Shi’a group, are allied with Iran and receive material and technical support from Iran. However, they are rooted in Yemen’s socio-cultural matrix. Unlike Hezbollah, Iran has less control over the Houthis’ decision making. Iran can and does limit the operational breadth of Hezbollah and its other proxies. In the case of the Houthis, the most senior leadership, among whom all decisions of consequence are made, is closed to all but the highest-ranking members of the organization.

It is possible that Iran had no foreknowledge of the Houthis’ decision to launch missiles toward Israel.
