It is accepted history that the Japanese code was broken before the Pearl Harbor attack. WW2 began in 1939, NOT 1931. If you want to be a smart ass, at least your dates correct.
In September 1931 the Japanese invaded Manchuria and China and approximately 20 million Chinese died by the end of ww 2. But to some I have to conclude you are among them dead Chinese do not count.
And many on the fire would appreciated it (I am one of the many) if you could keep the discussion civil and not resort to the juvenile use of profanity and name calling.
