During the presidency of Barack Obama, the United States began providing Saudi Arabia with critical support to „sustain“ the Saudi Arabian–led intervention in the Yemeni Civil War,[1] later expanded during the presidency of Donald Trump.[2] This support included logistical and intelligence aid. Trump vetoed a bipartisan bill in 2019 aimed at stopping U.S. support for the Saudi-led coalition in Yemen. In 2021, Joe Biden vowed to halt U.S. support for the war, though U.S. arms sales to the coalition have continued.[3][4]

From 2015 to 2019, Saudi Arabia was reportedly the largest importer of U.S. arms.[2]
