Operation Cherry Blossoms at Night

Operation Cherry Blossoms at Night was a proposed Japanese military plan during World War II, aimed at launching a biological attack on the U.S. city of San Diego in 1945. The operation involved using plague-infected fleas to contaminate the water supply and intended to inflict significant casualties. While it demonstrated Japan's advanced biological warfare capabilities, the plan was never executed, largely due to Japan's weakened condition towards the end of the war. The operation highlights the extreme lengths to which nations might have considered resorting during wartime conflicts.
