Not to mention Jim Crow was still in full effect in the US at the time, but somehow wasn't deemed "Crime against humanity". The winners truly do control the history.
Was Jim Crow a federally organized policy bent on extermination? It was state level discrimination that Nazi Germany copied in 1933-1938 to deal with their “Jewish problem”. By 1939 you had formal government-enforced ghettos with forced labor (no equivalent in America at the time) and by 1941 you had mass extinction.
Don’t get me wrong - Jim Crow was horrific. But it was state level after effects of the civil war and failure to establish absolute dominance over the southern states in reconstruction. Cultural problems we fought a civil war over and we’re still dealing with today. But one difference of the goal with slavery and Jim Crow is subjugation not extermination
Subjugation or extermination, if it wasn't for the addition of "as part of a war of aggression" to the "Crimes against Humanity", the US would have been considered as participating in crimes against humanity at the same time they were partcipating in the Nuremberg trials.
It's thanks to the US, that crimes against humanity is only considered when there is an active war of aggression, precisely because Jim Crow was a current thing at that time.
