this was about the Japanese attack on Pearl Harbor, we are getting off topic here,
Basicaly simple, we never know if these top secret SAS documents are actually right (or any other top secret documents) cause we werent there, were not gods, but just giving out our own opinions here.
Officially, Washington was warned about a jap attack somewhere, doesnt mean in hawaii it was going to be.
if you watch the movie Pearl Harbor, it was pretty much like that, whereas the radar operators only saw a huge cloud...literrally. the japs were actually intelligent in their attacks, they knew that a B-17 bomber group practice run was going to return that day, so they used that to their own advantage. games of war may be fun but war itself isnt.
