I’m pretty sure he meant that Russia never won a war on their own outside their borders. In WW2 Germany had been softened up quite a bit by the Brits and Americans before Russian tanks were rolling into Berlin.
We have two ships passing in the night.
One side says that Russia was invaded during WWII, and distinguishes wars in which Russia was the country being invaded from wars in which Russia is the country that is the invader. The other side says, and I quote a particular freeper, “Regardless of how Russia got into WW2, Russia did win (with help from the rest of the world).” As written, the “other side,” which disregards whether Russia is being invaded or is the invader, is correct.
I will repeat that the “other side” doesn’t disagree that since 1904, Russia has lost one after another border war (Japan, Poland, etc.), and has several times after these defeats subsequently had an internal revolution.
And no other country ever won a war in Russia on their own.
Hitler was delusional if he thought he would ever be able to conquer Russia, and take control of it. First of all, it's too vast. It would never have happened. Secondly, Germany was never going to be able to keep up the mass production of the military machinery it needed to continue to wage war. The allied countries outproduced both Germany and Japan when it came to mass production. Hitler himself said he would have to wage constant war to achieve his goals, and keep what he'd conquered.
Germany was never going to be able to confiscate enough oil and gas resources, nor manufacture enough synthetic gas to successfully power their war machinery in order to win WWII. Hitler bit off more than he could chew, and ended up making the people of Germany reliant on Russian energy for 70+ years.
