That was such an annoying intro to that video I had to press stop
I'm not in favour of downplaying the importance of Russian action in WW2 because they're currently getting it wrong in Ukraine under an inept leader like Putin.
The UK would have been removed from the board if Germany hadn't felt the need to pivot towards Russia, and that's exactly how Churchill recalls it, too, it's not rose-tinted bullshit. We were fucked, France had been lost, Germany should have rightly won the entire West of Europe but for pesky Britain being an island.
Soviet Russia didn't do anything on their own, naturally, but they're no more self-aggrandizing than the Yanks, who have made film after film about how they saved the day lol
USA entered the fray 'officially' much too late, just as many modern day Republicans would have them do the same
again in the face of a Russian assault on Europe.
USA is a country that never learns from its mistakes but points the finger at everyone else. Fuck that. Just accept Soviet Russia won the day in WW2, causing Germany to panic and pivot. That's the truth of the situation.
