The Arab Center in DC – Exactly a decade ago, Saudi Arabia announced the launch of a military intervention in Yemen, promising to lead a coalition of more than 10 nations—although some would later end their participation—against the Houthi armed group, officially known as Ansar Allah, that had taken over power from President Abdrabbuh Mansur Hadi. Backed by the United States, Britain, and other Western states with arms and shared intelligence, on March 26, 2015, the Saudi coalition commenced airstrikes on Houthi-controlled areas, initiating a conflict that would drag on for years. Riyadh’s initial expectation of a swift, six-week military operation to defeat the Houthis became a prolonged and costly entanglement that has tested Saudi Arabia’s ability to impose its will on its neighbor and to force the Houthis to give up their control over a large part of Yemen.
