While Ukraine welcomed the nazi troops and actively aided extermination of local jews

Ukraine "welcomed" liberation from the Soviets because they were more brutal than the Nazis, though your nonsensical claim that they "AcTiVeLy AiDeD eXtErMiNaYsHuN oV lOcUl JoOz" is buggered by a five minute conversation with any Ukrainian Jew who survived that era.
This message has been brought to you by a born US citizen and two-war Purple-Heart recipient who now lives in Kharkiv and knows first-hand what the f**k he's talking about while your barking consists of the brainless talking points you are fed by watching RT and Tass in your mama's basement. That veteran is me.
Now run along and get back to playing Call of Duty with a fake Russian accent that you think makes you sound tough, little boy. Leave the real world to us adults.

Also, if I believed you could read, I'd hand you a history book with references to the Kremlin's own archives wherein the Soviet Military Command reported that the Red Army who ran the Nazis off of Soviet Soil was 80% Ukrainian, 15% Kazakh, and didn't have a single Russian in it except a handful of officers because the Russians had lost so many men against the Nazis at Leningrad that they were too chicken$#!t to face them again, so they hid behind Ukrainians and let them do the fighting instead.
