You realize that the Soviets were in Hitler’s side when shit started and wanted to annex a chunk of Poland and the east?
You also realize that your prime example dates back 80 years?
The Sovjets never were on Hitlers side. Hitler was very clear from the beginning what he thinks of the communists, that he mingled into a “jewish bolshevik” world conspiracy. The Hitler Stalin pact was to buy the SU time to prepare for an attack from the Nazis.
Also 80 years is not a long times in historical terms, when the measure is “ever”. Incidently a lot of the turning two blind eyes unconditional support for Israel now is justified with the Holocaust that was in exactly the same period of time.
