Note signed by Tojo (June 1945), left at a camp during the Bataan Death March http://home.att.net/~betsynewmark3/DebateonBomb.htm. Possible forgery since Tojo was no longer in power for over a year at the time of the discovery. Also, the Japanese homeland was not threatened with invasion at the time and it was common sense that the Philippines would be attacked before.
1940s
