I don't guess this is going to do my reputation much good, but here goes anyway.
During the time that Hitler slaughtered his six million:
Stalin systematically starved the entire population of the Ukraine, about forty millions, by confiscating all the food produced in that region, "Russia's breadbasket," and shipping it out in railcars.
Mao systematically murdered his fellow countrymen who did not express enough enthusiasm for his "agrarian revolt." I have seen numbers as high as 60 millions of Chinese dead by the hand of this agrarian reformer.
The Japanese were busily killing more than six million in places like Nanking, Singapore, the Phillipines, southeast asia for lack of enthusiasm for their "Greater East Asian Co-Prosperity Sphere." If the little bastards had gotten their hands on Australia, they would have wiped out every occidental face, every abo face on it. Why do you think they were in the Solomon Islands? It was certainly not, as the curators of the Smithsonian (during the Clitonista regime) would have us believe, that they were merely protecting their "unique way of life." The japs were out of room, even back then. And Australia is a big, big place.
So finally, creeping up on my point, we never hear of these other atrocities simply because the Jewish people are much, much better at propaganda about what happened to them during WW II than are all these other people - whose deaths in genocide far outstripped six million. They've got better PR people on the job, making sure none of us ever "forgets." And now they're behaving toward the Palestinians like the Germans behaved toward them.
What goes 'round, comes 'round.
