This week on Babel, Jon speaks with Helen Lackner, the author of the new book, Yemen: Poverty and Conflict, who has spent five decades covering Yemen. ​​​​​​​ They talk about how conflict has been endemic in Yemen for hundreds of years, how the current conflict fits into that history, and what a post-conflict Yemen could look like. Then, Jon continues the conversation with Natasha Hall and Caleb Harper about U.S. goals in Yemen and other conflict-affected countries in the Middle East.
