Those crazy innovative Japanese of WWII, with their balloon bombs and their 400 ft long subs found off the shores of Hawaii carrying diseased animals to be dropped on the unsuspecting populous:
An I-400 and I-401 were captured at sea a week after the Japanese surrendered in 1945. Their mission -- which was never completed -- reportedly was to use the aircraft to drop rats and insects infected with bubonic plague, cholera, typhus and other diseases on U.S. cities. When the bacteriological bombs could not be prepared in time, the mission was reportedly changed to bomb the Panama Canal.
What other shenanigans were the Axis powers up to?
