This book is an instance of "Anthropology at a Distance." Study of a culture through its literature, through newspaper clippings, through films and recordings, etc., was necessary when anthropologists aided the United States and its allies in World War II. Unable to visit Nazi Germany or Japan under Hirohito, anthropologists made use of the cultural materials to produce studies at a distance. They were attempting to understand the cultural patterns that might be driving their aggression and hoped to find possible weaknesses, or means of persuasion that had been missed.
