For all their alleged difficulties in ramping up production and/or procuring supplies, the U.S. and NATO are still 1000% better-positioned in this respect than Russia.
In a "war of attrition" between a NATO-backed Ukraine and a Russia that is standing more or less alone, Russia is doomed to become depleted first.

What are you smoking?
Have you missed the past 3 months in Ukraine?
Russia bought a bunch of Chinese military junk and were humiliatingly exposed by it in Ukraine. Cheap tires falling off multi million dollar anti-aircraft vehicles, unsecured radios leading to interceptions, etc.
