American Presidents have struck Yemen before, often pointing to the Authorization for the Use of Military Force, a joint resolution passed after 9/11, which gave the President the power to attack terrorist targets in foreign countries without a formal “declaration of war.” But Trump hasn’t invoked the A.U.M.F.; instead, he echoed aides who say that it is within the President’s constitutional power to launch attacks for defensive purposes. His predecessors, too, seemed to operate with that license: most recently, the Biden Administration continued to strike Houthi targets, without Congressional approval, even after taking the Houthis off the list of foreign terrorist organizations.
