On March 15, the United States launched a wave of attacks on Houthi targets in Yemen. The Trump administration had pledged to step up efforts initiated by President Biden to combat Houthi assaults on commercial shipping and U.S. regional assets.

Asher Grant-Sasson speaks with Jon Alterman, director of the CSIS Middle East Program, about the current state of play and the dilemmas confronting U.S. policymakers in dealing with the Houthis.
