Thats a very interesting video, Newfie, and its explains Russian success on the battlefield, where their huge advantage in manpower gives them an advantage in a war of attrition, but I think to focus only on the relative GDP and productive capacities of Russia and its allies vs. Ukraine and its allies doesn't tell the whole story.
You can't ignore one of the most important new factors in modern warfare, and that is technology. In particular, the importance of drones. The entire reason Ukraine was able to push back the first thrust of the Russian invasion towards Kiev was that Ukraine had drones and used them effectively to destroy fuel trucks and tanks and so block the Russian column from advancing. There was far far far more military power in that one Russian column then existed in all of Ukraine's military at that time, but Ukraine saved itself using technology.
Same thing with the battles between the Ukrainian navy and the Russian navy. The Ukrianian navy doesn't even have any ships, but nonetheless they have decimated the Russian black sea fleet and pushed them back to Russian using ship to sea cruise missiles, drones, and the brave little Ukrianian sea drones.
And we're starting to see it in the air war as well as Ukraine has driven Russian helicopters off and is now going after Russian bombers and even Russian A-50s command planes.
And finally, Ukraine is beginning to manufacture its own long range drones. Just in the last few days we've seen successful Ukrainian drone attacks on Russian fuel depots and LNG shipping depots as far north as St. Petersburg, well into the Russian heartland. Supposedly Ukraine is manufacturing a MILLION Of these long range drones so the attacks on critical infrastructure within the Russian heartland is only to grow.
