Pearl Harbor: Who Blundered?


It makes no difference, so far as responsibility for the disaster itself was concerned, whether the war could have been prevented by wiser statesmanship or more astute diplomacy—though this would have required a wholehearted and unified national determination which did not exist in America in 1941 and the years before. It makes no difference that on December 7 the President and the Secretary of State—like the civilian Secretaries of War and Navy—had their eyes fixed on the Japanese threat in Southeast Asia. They had repeatedly warned the military men that war had probably become unavoidable.

What does matter is that the civilian statesmen— however deft or clumsy, shrewd, or shortsighted—performed their difficult tasks of diplomacy and of administration confident that the military men would carry out their professional responsibilities by doing everything humanly possible to prepare for a war so clearly impending. They had every right to expect that—within the limits of scanty means available—the Armed Forces would be ready for any contingency.

The confidence and expectations of civilian leadership and of the nation were tragically dashed that Sunday morning twenty years ago.

Military failures were responsible for Pearl Harbor.

In Washington the most important of these were the following:

1. The War Department staff, over which General Marshall presided, was at the time a complicated but “one-man” shop, where delegation of responsibility was the exception rather than the rule. When Marshall was absent, the operational wheels tended to freeze. This situation was to some extent due to cumbersome organization, to some extent due to the personality of the Chief of Staff.

2. General Marshall, in a letter to General Short on February 7, 1941, stressed that “the risk of sabotage and the risk involved in a surprise raid by air and submarine [italics supplied] constitute the real perils of the [Hawaiian] situation.” Yet, although definitely warning General Short on November 27 of the threat of war, and ordering him to report the measures he would take in response, Marshall did not check up on those measures; moreover, he was unaware that Short had done no more than to take routine precautions against sabotage. And General Gerow, heading the War Plans Division of General Marshall’s General Staff—as he testified later in taking full responsibility for this slip—had not made any provision for following up operational orders. The net result was that both Marshall and Short remained the whole time in blissful ignorance of a vital misinterpretation of orders.

3. Marshall and Admiral Stark—and indeed all members of their staffs who knew the situation—permitted themselves to be hypnotized by the concrete evidence of the aggressive Japanese build-up in Southeast Asia which threatened our Philippines outpost. This theme, it will be remembered, ran as background to nearly all the warnings sent Hawaii. Thus succumbing to the illusory diagnosis of “enemy probable intentions,” both top commanders ignored the danger implicit in our inability to locate at least four Japanese carriers.

4. Finally, on December 7, having indicated his full realization of the significance of the “one o’clock” intercept—that less than two hours now separated peace and war—and having decided not to use his “scrambler” telephone, Marshall failed to require surveillance and positive report on the delivery of his final warning.

These certainly were grave lapses in leadership. Yet in fairness, it should be noted that the consequences might not have been disastrous if all subordinate commanders had taken adequate security measures on the basis of the instructions, information, and warnings which they had received. To General Marshall’s credit one must also chalk up his ability to profit by his mistakes. In less than three months after Pearl Harbor, he completely reorganized the War Department, decentralizing the mass of relatively minor administrative and executive matters that choked major strategical and tactical decisions. His newly created Operations Division of the General Staff—which he aptly termed his “command post”—ensured co-ordinated action and direction of Army activities in theaters of war all around the globe. On Oahu the situation was less ambiguous: military leadership at the top failed utterly.

Twenty years later, with war clouds again lowering over most of the world, the story of the Pearl Harbor disaster has more significance than mere passing memorials to the brave men who lost their lives that day. If the lessons are heeded, our surviving descendants may never again have to commemorate another “day of infamy.”
