LOL the hell there was.. Stop this revisionist crap. The Soviets were part of the Allies and key member. Without them the Allies would never have won. It was not the Allies and the Soviets, it was the Allies full stop and that included the UK, France, Poland at the start and later on the Soviets added and even later the US. There was other nations also btw.. governments in exile and so on, but the big wigs were the UK, France, USSR and the US.
But yes Stalin was just as bad.. well in my view worse actually, than Hitler, but that does not change the fact that Hilter was used as a scapegoat by all the Allies.
The Soviets blamed him and Nazi Germany for massacares they did for example. The Soviets killed the polish officers and blamed the Germans. The Soviets used KGB troops to kill normal troops who fled and blamed often the Germans for the deaths.
The US and UK blamed Hitler and his cronies for the disappearance of art across Europe and then decades later they suddenly turn up in US or UK "ownership". While I have no doubt the Nazi's stole a buttload of art, it is also very evident that allied troops "liberated" some of that and took it home. The western Allies blamed the Germans for bombing their cities.. yes that was true, but they still got the blame when the Allies went and killed 10s of thousands in deliberately set fire storms in German cities. Sure it was war, but the Germans got the blame for their own fate, and the people who actually made the call to use such a diabolical weapon got off scot free.
Or the modern myth that has been promoted since the war, that it was Hitler that basically started the eugenics programs with forced sterilizations, and targeted Jews or people looking like Jews for discrimination. No he did not, far from it. That came from the US and Sweden pretty much, but he gets all the blame despite the practices being used all the way up to the late 1970s among "Allied nations". We all cringe at the fact that handicapped and other undesirables were forced sterilized and even killed in Germany, but very few know that this was happening in the US, Sweden and other places long before Hitler even got to power.
Sorry but Hitler gets blamed for many things, much of it fully justified, but some of it was in no way his fault or that of Nazi Germany.
