Great summary. Though i would dispute the completeness of the “domestic genocides” category. Denmark pretty much instantly willingly submitted to Germany and actively collaborated in Nazi policies of extermination. As did Vichy France and significant portions of Belgium and the Netherlands, so much so that the Nazis formed entire SS divisions out of them. And of course Austria cannot claim to be innocent as the Anschluss had significant support among Austrians, as did the repression and extermination policies that followed.

Much more of Europe has blood on their hands for the crimes of fascism than just Germany. Like the war of extermination against the Soviet Union, fascism was a pan-European project, not an exclusively German (or Italian) one.

And Japan should be counted in that category of domestic genociders as well for their genocide of the Ainu people of Hokkaido. And they are still colonizing Okinawa.
