Then there was the plan in which the White House and Pentagon pretended they were "surprised" by the "sneak attack" on Pearl Harbor.
You sound like Walt Cakebread. There was no Pentagon at the time of Pearl Harbor. And they
were stunned at the attack. No one thought the Japanese (or any navy) had the ability at that time to coordinate a multi-carrier attack on a base. It had never been done. They expected an attack; where and how and in what form was not known. But they certainly didn't think the Japanese could covertly move an entire task force of that size and strike like they did. It was unprecedented.
It wasn't just the US that was caught by surprise. The British and Dutch forces in the East - Malaya, Singapore, Hong Kong, Dutch East Indies, et cetera - were surprised as well. And those came shortly *after* Pearl.
