“So, even if Germany had not attacked Russia, the Russians would have moved against them eventually.”
It’s an interesting subject to discuss. The Russians were very impressed with the ease that the Germans defeated France. From everything I’ve studied about WWII, I doubt Stalin wanted to attack the Germans. He knew full well the power of the Wehrmacht. The Allies would never have been able to overthrow the 3rd Reich without the Russians, at least not until we eventually got the bomb. Even then, it would have been an unimaginable blood bath.
That’s a good point, too. I guess it comes down to how Stalin would have evaluated Germany’s determination to hold Poland ... and we can’t know.
And pretty much all their weaknesses via unfettered access to German armaments production facilities per non-agression pact.
