In this photo taken, Thursday, May 10, 2012, Joint Chiefs Chairman Gen. Martin E. Dempsey speaks during a briefing at the Pentagon. A course for U.S. military officers was teaching that America is at war with Muslims, suggesting the U.S. ultimately may have to wipe out Islamic holy cities like Mecca and Medina just as it destroyed Hiroshima in World War II. That teaching is counter to repeated assertions by U.S. officials over the last decade that the U.S. is at war against terrorists who distort Islam _ not against the religion itself. The Defense Department suspended the course at the Joint Forces Staff College last month due to the inflammatory materials, but details of what was taught were first revealed Thursday. Dempsey called the material objectionable, irresponsible and against American values on freedom of religion. (AP Photo/Susan Walsh)
