Bomb plots, light signals (ending Dec. 6th), Japanese spy in consulate. FBI and Washington knew. Did Kimmel/Short???
Where is JD #7001 (Japanese Dispatch #7001)? Layton shows index with it missing. SRH-051 (declassified March 11, 1980 interview) has Briggs recalling he intercepted it [People were on "alert" to look for same you may recall]. Safford says he saw it; Kramer changed his mind, and Clausen proved it never existed. Don't forget Lt. Linn's comments, also.
After Toland's Postscript (second edition) ... SS Lurline radio log got "legs" out of the Archives.
And did Nave and Mortimer get it "right" on FECB's success in breaking Japanese naval codes? What happened to those British warships (Repulse, Prince of Wales)? Was the delay in intercept/decypher/ ... four (4) hours too long a time to save them ... or just poor CAP? ... Comments?
As to the SS Lurline logs, these were Japanese commercial transmissions in the commercial shipping band, not Japanese naval transmissions from the Kido Butai. You should also know that the records custodian that Stinnett quoted is very angry that he grossly misquoted her accounting of these files in San Bruno. Typical Stinnett SOP. Stinnett also referred to them as Navy files when they were actually Coast Guard files.
As to Nave and Rusbridgers revisionist conspiracy book, "Betrayal at Pearl Harbor," Nave completely reversed himself on Japanese TV admitting that Rusbridgers allegations were fantacies. I have a tape of that program in Japanese. Recent releases of British cryptologic documents from Kew show that the British were, if anything, behind the U.S. in decrypting JN-25B and that they had only recovered some 3,000 code values out of over 55,000 and only ten percent of the additive book used up to 4 December 1941. This equates on average to one group out of every 100 in a message. Thus your theory that Churchill warned Roosevelt of the impending Pearl Harbor attack is baseless also.
