It would be reassuring to believe that Pearl Harbor was just a colossal and extraordinary blunder. What is disquieting is that it was a supremely ordinary blunder. In fact, 'blunder' is too specific; our stupendous unreadiness at Pearl Harbor was neither a Sunday-morning, nor a Hawaiian, phenomenon. It was just a dramatic failure of a remarkably well-informed government to call the next enemy move in a cold-war crisis.
