Russia is interesting though, because with so much land, arguably they can be self sufficient, which means only intelligence & innovation holds them back if they want to turn inwards like China did, which the Brits exploited commercially through Hong Kong.
Russia have already demonstrated intelligence and innovation during the cold war with sputnik, they also have tried and tested rocket technology which will boost the French Ariana rockets but we know that genius individuals are distributed around the planet although the health of the mother, diet during pregnancy & during the first 8years will go along way to helping a genius. But the West has pollution which is lowering IQ levels, just like Covid is lowering IQ levels as seen with the "brain fog", so I wouldnt write them off if they followed the science and wanted to go isolationist. Even North Korea has shown it can still survive albeit at a slower pace to the rest of the world, but nothing like the Nazi war effort, which goes to show how idea's can motivate groups of people.
