This week on Babel, Jon speaks with Tim Lenderking, the U.S. special envoy to Yemen. They speak about the UN-negotiated ceasefire in Yemen, recent U.S. diplomatic efforts in the country, and what makes the current moment in Yemen different than other openings in the past. Then, Jon, Will Todman, and Caleb Harper continue the conversation about the interplay between U.S. and UN diplomatic engagement in Yemen, and in the rest of the region.
