I can’t bring myself to thumb this up, though it’s an historical item. The Second World War is usually documented from the American perspective, or about the Holocaust. It’s important to note that there was a second front in Asia, and that it witnessed some equally horrific atrocities in the name of “science”. The Japanese/German alliance always seemed unlikely to me, but there’s no denying they did have similar, sick interests in using subjugated peoples as their guinea pigs.
