HMM: Declassified Memo Hinted of 1941 Hawaii Attack. “Three days before the Dec. 7, 1941 Japanese attack on Pearl Harbor, President Roosevelt was warned in a memo from naval intelligence that Tokyo’s military and spy network was focused on Hawaii, a new and eerie reminder of FDR’s failure to act on a basket load of tips that war was near.”

There’s a new book, so this claim’s getting attention, but in William Patterson’s biography of Robert Heinlein I learned that while in the Navy Heinlein was involved in a Pearl Harbor carrier-attack wargame that eerily presaged Pearl Harbor. The Navy’s battleship mafia deep-sixed the report, but the Japanese noticed.
