It’s amazing but in fact he is correct:
Unit 731 was evil on the scale of the Third Reich but an accident of History saved most of the men from prosecution.
Unit 731 accumulated a lot of medical data about biowarfare and at the close of World War II the growing American fear was what might happen on the Korean Peninsula:
An evil bargain was struck; the US received all of Unit 731’s biowarfare data and the Japanese culprits went almost completely free.
Many of the Unit’s top officers went on to become huge capitalists, Millionaires and in the case of one, a prime minister.
See post # 64
IIRC, there is still a strain of cholera created by unit 731 that is still active in China.
Another memory from reading somewhere is that the Japanese leader of the Chinese occupation was a corrupt, drug addicted SOB who ordered cigarettes to be laced with opium in order to addict the population.
Millions were addicted and the money they paid for the drug was used to fund the war effort. (after being skimmed off by the Japanese leaders in China.)
