When one reads about the true events leading up to the Pearl Harbor sneak attack, many of the problems and signals were either ignored or neglected by higher ups, people in authority, heads of state or cabinet level positions or by the military itself. It was disgraceful to say the least.
From what I’ve read I(I wasn’t around at the time), nobody in the upper echelons was too concerned, it being Sunday morning and all. Even on Oahu, the radarmen secured at 0600.
