"In actual practice much of the Pacific war was devised by Admirals King and Nimitz. They were thus thrown into the closest cooperation, though most of the time they were far apart geographically. They maintained a constant dialogue in the form of radio dispatches, often several a day, letters, exchanges of representatives, and periodic meetings, usually in the Federal Building, San Francisco, King flying there from Washington and Nimitz from his headquarters in the Pacific. Though Admiral King's tone in communicating with Nimitz was occasionally acerbic, as was his nature, it is clear that the two commanders greatly respected each other. At the end of the war, King recommended Nimitz to be his successor as Chief of Naval Operations. Although their styles were in sharp contrast, King and Nimitz were more alike than different. Simplicity and directness were the keynotes of their characters. They were both dedicated to their country and to the Navy, though King's interests were more narrowly naval. Both were men of integrity and keen intelligence, and both were born strategists and organizers, with a genius for clarifying and simplifying and a jaundiced eye for the useless complications and waste emotion. Their chief difference lay in their attitudes toward their fellow human beings. King had little of Nimitz's understanding of, and empathy for, people. Said one of King's wartime associates, "Every great man has his blind spot, and his was personnel." King went to great lengths to draw into his command the sort of men he wanted and to eliminate those he did not. The results were not always fortunate. Several cases of his placing the wrong man in the wrong spot for the wrong reasons could be cited."
