Also worth noting that along with Operation Paperclip, where the US recruited Nazis to bootstrap their space program, the US also recruited Japanese war criminals to continue their experimentation in torture and chemical and biological warfare, which led to (among other things) MKULTRA.
And in Bluebird and Artichoke the US directly continued that work, and not in some kind of "generic spirit" way, but in literal extensions of existing programs using people gathered via Paperclip. And in Korea the US used bioweapons developed by the Japanese during a retreat in late 1952.
The Japanese were indeed horrible during the war. The take that the Germans and the US treatment of "expendable" humans during and after these wars was somehow more justified or less horrific is a uniquely horrible and ahistorical take.
