Geopol, History, Racism
Don't forget, the second world war was a Race War Of Annihilation on all fronts.
In Europe, two evil empires fought until the Nazi Germans were obliterated by the Soviet Red Army.
In East Asia, the Yamato People and their imperial army kept fighting that war into the 1970s in places, even after we'd firebombed, nuked, and rebuilt their country.
And all this, in an era when institutional, state sponsored race supremacy had it's high water mark. What turned it back was perhaps more horrifying than concentration camps or Nanking. Keep this in mind as we confront the racism of the 21'st century.
Nukes might be required again, and we haven't seen the racism get bad yet. Ask the Armenians how bad it can get. The Uighur are suffering that bad, Right Now.
