I wonder if Russian history mentions that the Soviets invaded Poland in cooperation with the Germans?
They are doing it in a strange way. Up until the 1990 they were denying the existence of the secret protocols and calling it a western lie. Their version of history relied on claiming these never existed. There is a documentary about when it was revealed. Filmmakers go to their Supreme Soviet to see the reaction of these commie deputies and these people are absolutely shocked and devastated when finding out the truth about it. Then couple of decades later Russians have gone back to the Soviet version of history, but now it doesn’t make logical sense any more as they can’t undeny the secret protocols. They’re teaching it anyway and nobody cares about the logic.
