Ahh, finally I was able to watch it in it's entirety. I found that part 3 was the only section that required a log-on. I watched all the other sections on YouTube and found part 3 on another website. What a process.
Still, with some variations, the series seemed commensurate with what I've read about Nazis medical experiments in Europe. I wonder what would've happened if the Americans (in Europe), had not found the evidence of medical experiments before the Nazis were able to destroy it, or even conceal it for future bargaining. The only difference, aside from mass exterminations using various inhumane methods in Europe, was the scale with which the Japanese deployed their biological experiments. The Japanese seemed more indifferent to life in general, but then again, they used to kill themselves en masse with ritual seppuku or in pointless Banzai charges against vastly superior firepower. In that respect, their inhumanity is no surprise. I've read some equally horrific stories about Nazi medical experiments, some of which seemed to have no medical purpose whatsoever.
