The almost four-year long brutal civil war in Yemen between the central government of President Abdu Rabbu Mansour Hadi and a Shi’a Islamic movement called the Houthis shows no signs of slowing. A coalition of countries led by Saudi Arabia has provided extensive support to President Hadi, including by conducting an ongoing military campaign against the Houthis. In the course of this military campaign, the Saudi-led coalition has been accused of violating international humanitarian law by killing hundreds of civilians through airstrikes, as well as contributing to a humanitarian disaster by imposing a blockade. Though not a member of the Saudi-led coalition, the United States has provided invaluable support to the coalition’s campaign through weapons sales, mid-air refueling of coalition aircraft, targeting assistance, and other training and logistical support. This Article surveys and analyzes a variety of domestic and international law that may apply to the U.S. role in Yemen and finds that continued U.S. support for the Saudi-led coalition in Yemen may violate several domestic and international laws. The article concludes by considering whether and how the laws might be enforced and U.S. legal violations brought to an end.
