If the whole of NATO was actually sending all their stuff they produce from their factories to Ukraine (everything from F-16, F-18EX, F-35 to tanks and other ground vehicles etc.), then yea, time definitely wouldn't be on Russia's side.So, Russia with an economy about 10x smaller than NATO has time on its side? Hunderds of Armatas, Su-57, Kurganets, Boomerangs etc. are rolling from factory lines daily?
But it's pretty darn clear they aren't doing that, and so in comparison to what Ukraine is getting vs what Russia is making and sending to its frontline, we have Russia > Ukraine, and therefore also time on Russia's side (and it's manufacturing 'outperforming' Ukraine backed by the west/NATO).
