"Historians have concluded that Truman grew into the role of commander in chief, and eventually proved more than equal to the job. But in the spring and summer of 1945, the growing pains were evident- and the decisions he must confront during those early weeks were among the most important of his presidency. In his diary, Bill Leahy expressed concern about the "staggering burdens of war and peace that [Truman] must carry." Privately, according to Leahy's son, the admiral regarded his new boss as a "bush-leaguer." He had been accustomed to speaking his mind to Roosevelt, knowing that the late president was "captain of the team" and might accept or reject his advice according to his own judgment. But Truman did not yet possess the confidence or independence to buck his advisers. Truman was in their hands, Leahy told another aide, which meant everyone who advised the president bore heavy responsibility, and must be absolutely sure they were right. In his diary and his subsequent memoir, Leahy betrayed no sense of responsibility or culpability for the new president's relative ignorance. One is struck by this lack of self-awareness in a Washington statesman otherwise respected for his wisdom and good judgment. Whatever he knew or did not know about the state of FDR's declining health, Leahy had been at the late president's elbow for most of the last year of his life. He certainly knew enough to anticipate that Truman might be thrust into the role of commander in chief at any moment. Leahy was the White House chief of staff and the chairman of the JCS. What steps did he take to ensure that the vice president was properly briefed? Who else had that duty, if not himself? No adequate explanation has ever been provided for this breakdown in the basic procedures of sound constitutional government."
