Matt Crawford speaks with professor and author Dr. Susan Carruthers about her book, Dear John. Are Dear John letters a betrayal of love and country? What type of person would send such a letter to a service member serving overseas risking their lives? Dr. Carruthers and I discuss that and so much more regarding this complex and nuanced issue. From the evolution of spousal communication to the military's changing policy on relationships and marriage in general, this is a book that looks at the administrative and psychological aspects of it all.
