Exactly. You made my point. The USSR and Nazi Germany BOTH started WWII with their invasion of Poland.
While Hitler was absorbing Austria and Czechoslovakia into the Reich, the USSR attacked Finland and invaded and occupied Estonia, Latvia, and Lithuania.
While murdered 6 million Jews, the Soviets slaughtered 8 million Ukrainians.
Yes indeed Hitler and Stalin were partners in crime as they divided Europe up among themselves and engaged in genocide. Facts almost completely ignored by contemporary history.
For me watching the Soviets and Nazis fighting eachother was much like watching the Iran/Iraq War. You hope both sides lose.
To top it off, I read an article a few days ago of some Rooskie minister blaming WW2 on Poland!!
