In 1966 I spent fifty-five days in Vietnam observing the air war firsthand and wrote a book, Air War—Vietnam. It went to six editions. It was reprinted almost in its entirety in the official Pentagon publication to show how well our troops were doing and how just our case was; it was quoted extensively in liberal publications and by campus protestors to show how badly our troops were doing and how unjust our cause was. American fighter pilots in one F-100 squadron elected me to their inner circle of gungho operators which they called “Sierra Hotel” (decorum forbids a translation of the code words). I. F. Stone reprinted my napalm sequence; Dr. Spock's lawyers phoned to ask me to appear at his trial in his behalf; my local American Legion Post invited me to speak at their annual Memorial Day ceremony.
