"To King, Leahy, Nimitz, and naval officers in general, it had always seemed that the defeat of Japan could be accomplished by sea and air power alone, without the necessity of actual invasion by the Japanese home islands by ground troops. In 1942, 1943 and 1944, while attention of most of the Allied political and military leaders was focused on Europe, and while the war in Japan was left largely to King to manage with what forces he could muster, the Pacific war had proceeded largely upon this assumption. With the approaching victory in Europe a larger amount of attention was concentrated on the Pacific by people who had not previously been too greatly concerned with the problems of that war, and an increasing amount of high-priced thought was devoted to it, some of which seemed to King not strictly pertinent. From the time of the Teheran Conference there had been the political consideration of Soviet intervention in the war against Japan, and the Army had been convinced that the use of ground troops would be necessary. Upon Marshall's insistence, which also reflected MacArthur's views, the Joint Chiefs had prepared plans for landings in Kyushu and eventually in the Tokyo plain. King and Leahy did not like the idea, but as unanimous decisions were necessary in the Joint Chiefs meetings, they reluctantly acquiesced, feeling that in the end sea power would accomplish the defeat of Japan, as proved to be the case."
