It makes little difference 1 way or the other now. As Nazis have continued to be prosecuted and punished (last execution of a Nazi happened in 1966 in former East Germany) even as last 1 dies off, perpetrators of Stalin’s Holocaust-Holodomor were not punished. Final Solution was about exterminating Jewry. Holodomor or Soviet Holocaust in early 1930s where millions were killed by being starved to death in famine (esp. Ukraine), beaten, shot and worked to death in GULag or building Soviet Railroad went unpunished. Josef Stalin was a ruthless dictator who took more lives than Hitler. Incidentally, some of Stalin’s henchmen were Jewish such as Lazar Kaganovich, Genrikh Yagoda and Lev Mekhlis. No, they didn’t do it because of Judaism but because they were Communists.
There were no courts to punish them and they were only prisoned or executed if they became a threat to Soviet leadership. Ironically, the Nazis executed some Stalin’s henchmen during Operation Barbarossa by the Commissar Order. Lithuanians, Latvians, Estonians and Ukrainians fought on the side of Wehrmacht (German Armed Forces) against Soviet Red Army during Operation Barbarossa in Stalingrad and Leningrad Battles as tjeu wamted to be free of USSR. Yes, Nazis did bad things especially with Holocaust extermination of Jewry. Nazis sometimes killed bad people-of course if you’re killing millions in a war, you’ll sometimes kill bad people such as Stalin’s henchmen. We have continued to pursue Nazi war criminals so many years after the war, but Stalin’s henchmen have gotten away with it. With Nazi Germany’s ally Imperial Japan, other than the Tokyo, Manila and Nanking trials, we haven’t to my knowledge prosecuted Japanese soldiers who took part in Bataan Massacre, etc. Shiro Ishii who did parachuted fleabombs (similar to daisy cutters in Vietnam only that it carried plague, typhoid and anthrax viruses) was not punished for what he did and he died in 1957.
