Question about WWII; I came across Unit 731, and was wondering why the US had the authority/right to grant Japanese Unit 731 immunity from war crime trials, in exchange for the human experimentation results (just to the US but not other allies)?
Also - I'm researching more - but from what I've read, so far, it seems like the post-war treatments Japan received were softer in a degree compared to that of Germany? For instance, Japan was free from trials whilst the Nuremberg and Doctor's trials were aimed at the Nazis.
