I like you, so I'm gonna say this for the final time.
Bro, please stop this pro-Russian advocacy, it's cringe.
Wagner itself started out as a neo-nazi group.
The Russians commit massive war crimes with dozens of mass graves found from recaptured areas.
The Russian industrial war machine as you put it has failed to do anything. This is why they're started to use tanks from ww2 and early cold war. It's also why they have had to buy weapons from foreign sources.
NATO and the US aren't fighting Russia, they're helping Ukraine fight off Russia.
If NATO got directly involved, Russia would have seen a total collapse of its military by now.
The Russians took a single unimportant city, losing 50k to 70K soldiers. They didn't win anything, they've now screwed themselves, because the Ukrainians are out flanking them. The Russians are gonna lose Bakhmut soon enough.
