Since mid-November, the de-facto authorities in most of Yemen, the Houthis, have launched dozens of attacks on commercial ships in the Red Sea. The Houthis say they are doing this in response to Israel's war in Gaza and these attacks have severely disrupted a key global shipping lane. The United States and the United Kingdom have launched missile strikes against Houthi targets in Yemen in retaliation, and to deter future attacks on shipping in the Red Sea. 

My guest today, Gregory D. Johnsen, is a non-resident fellow at the Arab Gulf States Institute in Washington. He is currently the associate director of the Institute for Future Conflict at the U.S. Air Force Academy. He is a longtime Yemen watcher who served on the UN Security Council's Panel of Experts on Yemen. 

We kick off with a brief background on the Houthis and their role in Yemen's civil wars. We spend most of this conversation discussing the motivation behind the Houthi attacks and why airstrikes are not likely to deter future Houthi attacks in the Red Sea.
