The Germans have always been better individual fighters.
No, they haven't. You missed the point spectacularly.
Polish or even Russian individual soldier was every bit as good, tough and brave as a German one. But they were better commanded, had better tactics, modern weapons and communication systems, could react much faster on the battlefield, and had incomparably stronger industry behind them (at least at the beginning of the war). That's why our soldiers in 1939 could perform miracles of heroism and still get slaughtered by thousands with much lower German losses.
in WW1 and shortly after
But all that was for precisely the same reason! They were much richer than poor, farming-based, stitched together from the three partitions Poland and were an industrial powerhouse compared to us in 1939 but the moment the USA joined the war, the very same mechanism took place - they were against a country that were much richer, modern and industrialized than they were. Their defeat became just a question of time.

Nuclear weapons? Yes, they are an aberration that introduces an unpredictable variable to the previous system. They are also what prevents modern-day Russia from collapse.
this capability
What Russia still has, apart from nukes, is the ability to replace losses - to regenerate and keep throwing reserves at their enemies whilst disregarding (to some extent) the cost. Something has changed though, also in this aspect. Russia can no longer disregard the cost the way they used to. If they wanted to mobilize and overrun Ukraine, they could do it. But the cost, and the cost of occupation, would prove too high and your high command knows this. Russia in general is very good at poker and calling other countries bluffs (the way you play with Brits is painful to watch how they make retards of themselves constantly) but this time it was you who bluffed and whose bluff was called. Hm... let's stop here for the time being.
I don't follow your logic
There is precious little that you follow, Milo, apart from too many retarded YT channels. Give up youtube for three months and in this time read sources from both side of the conflict, think and analyze. Then come back and talk to me. But you have to promise - no YT for at least three months. Zero.
