Some US officials have started using the word "daesh" to refer to ISIS, or ISIL, because it separates the group from Islam and from having a state (plus, they hate it). So we asked Muslim listeners how they feel about the word and whether the terrorist group represents a distorted branch of their faith, or something else altogether.

And we asked David Sanger, national security correspondent for The New York Times and author of Confront and Conceal: Obama's Secret Wars and Surprising Use of American Power, how the US campaign against ISIS is going, if it's a "war" or not, and whether ground troops might be necessary.
