This week on Babel, Jon talks with Peter Salisbury, the International Crisis Group's senior analyst for Yemen with over a decade of experience working on the country. They discuss who's fighting in Yemen, what's at stake in the ongoing battle over Marib, and why the international community needs to broaden its mediation efforts to end the Yemeni conflict. Then, Will Todman, Danny Sharp, and Jon discuss what role the United States should play in Yemen and how the country fits into broader U.S. strategy in the Middle East.  Peter Salisbury, “A New UN Envoy is an Opportunity for a New Approach in Yemen,” International Crisis Group, June 18, 2021.  Peter Salisbury, “To Make Yemen’s Peace Process Sustainable, Include Women,” World Politics Review, April 19, 2021.  Peter Salisbury, “Yemen’s Southern Transitional Council: A Delicate Balancing Act,” Istituto Per Gli Studi Di Politica Internazionale (ISPI), March 29, 2021.  Jon Alterman, "Designating the Houthis as Terrorists Would Be a Mistake," Defense One, November 30, 2021.
