Which never happened since nobody knew this.
Please none of the 'they broke the codes' bull****.

The IJN didnt transmit the details of this operation,
it was hand carried and the fleet maintained radio silence

No,Sir almost everbody in Washington DC,but surely the names mentioned above as
all them were informed about attack by Col.Bratton and Thurman personaly.
On Nov.28 They officially informed Hull,Stimson and Knox about japanese fleets
target.They did not respond.
On eve of Pearl Harbor attack the same team intercepted and decipher the famous
message to Nomura.
Thurman took the message immediately to Adm.Kramer.He took the message but did
not do anything.
Thurman tried to contact Stark,Turner and Marshall,no avail, apparently nobody
in Washington DC wants to do something to prevent Pearl Harbor.
As last resort Thurman went directly to White House with a car driven by his
wife and wanted to speak with FDR directly.
But instead of FDR he was ablr to speak to Harry Hopkins.

So,Mr.Willshaw after Nov.28 Pearl Harbor attack was not surprise attack to
anybody in Washington DC,it was a very welcomed opportunity.
In other words,Washington was decided to make it happen for domestic politics.

Kimmel was fired, I really dont see him staying
silent in such a situation.

Firing is not a very heavy punishment form
