> For the first 3 years of WW2 USSR was an ally of nazis.
This sounds inaccurate or at best an oversimplification of the complicated pre-WW2 treaties flying all over europe. I only see this idea in reference to the Molotov–Ribbentrop Pact, but that only lasted 2 years and was a non-aggression pact, not an alliance. But maybe you are talking about a different agreement?
