This look at WW2 in the Pacific by mil. historians examines the possibilities of the ways not taken: the opportunities for decisive advantages that could have been won by the arms of Imperial Japan. What would have happened if, for example, Japan had followed up its plan to attack the Soviet Union rather than the U.S.? Or if Nagumo had sent in his 3rd wave at Pearl Harbor: What if Japan had conquered India & knocked Britain out of the Pacific War, or if Japanese landings in Australia had severed the strategic link between the U.S. & its SW Pacific base? The authors, writing as if these & other world-changing events had actually happened, project realistic scenarios based on the true capabilities & circumstances of the forces involved. Illustrations.
