I don’t think Russia saved Europe from Napoleon. Britain did. Actually I think Napoleon would have been defeated anyway simply because he didn’t have the “right idea” for the nineteenth century — England did. I don’t think anybody won WW1 unless it was the US, which was the only country not to be harmed by both world wars. The Russians and the Germans in WW2 is a complicated, pregnant subject. It hasn’t been fully explored. Russia could hardly have defeated Germany when it was much worse off at the end of the war than Germany was. Also groups in Eastern Europe and maybe even Russia were helping certain Nazis with the Holocaust. It’s certain. Russia supposedly has destroyed its records and has erased all mention of the subject. Also Russia has followed Germany for the past several hundred years. It prospers only when Germany does. You can’t separate the two countries.
