President Joe Biden announced U.S. airstrikes on the Houthi movement, one of two competing factions claiming to be Yemen's government, on Thursday. The attacks came after Houthi drone and missile attacks on trade routes in the Red Sea, which Houthi leadership said was meant to pressure Israel to lift its siege on Gaza. Several members of Congress from both parties said that Biden had no constitutional authority to attack. Biden justified the strikes in terms of self-defense.
It was a new escalation, and it wasn't. The United States has been involved in Yemen for years, striking Al Qaeda and supporting a Saudi-led coalition against the Houthis. But Thursday was the first open combat between the U.S. military and Houthi forces, except for a limited incident in 2016. It was also the first airstrike in Yemen by anyone in nearly two years. Saudi Arabia had accepted a truce and peace talks in early 2022, partly because of U.S. pressure.
