Unit 731 - The Secret Japanese Holocaust

For some reason it wont let me embed the video here, but please go here and check out this youtube video.

I guess it isn't surprising that I was never taught about this in high school.

This is horrifying and disgusting.

Here is a small excerpt from wikipedia about unit 731. You can see the full page here. Keep in mind that this is just one small part of what they did to their victims.

Vivisection
Prisoners of war were subjected to vivisection without anesthesia. [7][6]
Vivisections were performed on prisoners after infecting them with various diseases. Scientists performed invasive surgery on prisoners, removing organs to study the effects of disease on the human body. These were conducted while the patients were alive because it was felt that the decomposition process would affect the results.[8][6] The infected and vivisected prisoners included men, women, children, and infants.[9]
Vivisections were also performed on pregnant women, sometimes impregnated by doctors, and the fetus removed.[10]
Prisoners had limbs amputated in order to study blood loss.[6]
Those limbs that were removed were sometimes re-attached to the opposite sides of the body.[6]
Some prisoners' limbs were frozen and amputated, while others had limbs frozen then thawed to study the effects of the resultant untreated gangrene and rotting.
Some prisoners had their stomachs surgically removed and the esophagus reattached to the intestines.[6]
Parts of the brain, lungs, liver, etc. were removed from some prisoners.[11][7][6]


They also did germ warfare testing, weapons testing, as well as other forms of torture to these chinese civilians.
