Because you seem to have this wild fantasy that Russia is still the Soviet Union, with the world's second best military. You're completely unwilling to accept any of the major, glaring flaws in Russia's military. Whilst I know Bret is on a wind up, you seem to believe all this stuff is genuine. You seem to be equating Ukraine, armed with donated weapons, with actual armed forces from NATO countries.
Vast swaythes of the Russian airforce sits rusting away on disused airfields, overgrowing with weeds, whilst you seem to equate these aircraft to F35s because, "Russia gets more bang for their buck and are self sufficient." They aren't. They don't have anything like the supply chain or expertise to match the west. Corruption, bureaucracy and inefficiency are absolutely rampant.
