Dower, John W. "War without mercy : race & power in the pacific war" : Pantheon Book, 1986.
Dower's premise in War without Mercy is a startling one: Though Western allies were clearly headed for victory, pure racism fueled the continuation and intensification of hostilities in the Pacific theater during the final year of World War II, a period that saw as many casualties as in the first five years of the conflict combined. Dower doesn't reach this disturbing conclusion lightly. He combed through piles of propaganda films, news articles, military documents, cartoons--even entries in academic journals in researching this book. Though his case is strong, Dower minimizes other factors, such as the protracted negotiations between the West and the Japanese.
