The last 70 years of modern warfare have been filled with atrocities, from the first bomb that exploded the tranquility of Pearl Harbor on the morning of December 7, 1941 to the advent of large-scale saturation bombing of civilian centers culminating in the atomic bombings of Hiroshima and Nagasaki, from the terror attacks of 9/11 to the ill-advised invasion of Iraq and subsequent quagmire. In his ambitious and comprehensive comparative study Cultures of War, historian John Dower exposes many striking similarities between the thoughts, actions, and attitudes of Imperial Japan, the United States, and radical Islamists.
