I don't think she's an evil bitch just a product of the Japanese education system that didn't teach her about the atrocities that the Japanese committed during the Pacific War.
But the US is complicit too. The story goes that when Japanese officials signed the surrender they agreed to hand over all their medical and biological weapons research in exchange for immunity from war crimes.
The live experiments they were doing on Chinese in Manchuria were just as bad as the Nazis. If you haven't heard of Unit 731 then you're in for a shock. There is very little academic documentation on their atrocities.
For 40 years, the horrific activities of "Unit 731" remained one the most closely guarded secrets of World War II. It was not until 1984 that Japan acknowledged what it had long denied - vile experiments on humans conducted by the unit in preparation for germ warfare.
Unit 731 deliberately infected with plague, anthrax, cholera and other pathogens, an estimated 3,000 of enemy soldiers and civilians were used as guinea pigs. Some of the more horrific experiments included vivisection without anesthesia and pressure chambers to see how much a human could take before his eyes popped out.
Unit 731 was set up in 1938 in Japanese-occupied China with the aim of developing biological weapons. It also operated a secret research and experimental school in Shinjuku, central Tokyo. Its head was Lieutenant Shiro Ishii.
The unit was supported by Japanese universities and medical schools which supplied doctors and research staff. The picture now emerging about its activities is horrifying.
