I heard on the History channel once than the Japanesse sent the Plague over here in some balloons.

“In 1942, germ warfare specialists distributed dysentery, cholera and typhoid in Zhejiang Province in China but Japanese soldiers themselves became ill and 1,700 died of the diseases. An estimated 440,000 Chinese died of this germ warfare.”

[Some Japanese generals did propose bio-attacks on US, but they hoped that the balloon bombs would spread forest fires.]

Another scheme: “... codenamed Cherry Blossoms at Night, the plan was to use kamikaze pilots to infest California with the plague.”
