Funked, Soviet aircraft doctrine was mostly defencive. Imagine a barrier of SAMs from 250+km range S-200s, short-range low-alt S-125s, good ol' S-75s, supplied with targeting info by enormous grid of Radio-Technical Troops, with MiG-31s over their heads, each "zveno" covering ~1500km of frontline, with frontline firghters like MiG-29 or Su-27 used only as corks in the holes...
Any fighter even as good as F-22 will endure no more then 5 minutes after crossing the targeting range. So - it's quite clever to save your taxpayers money. You can bomb Afghan peasants "to stone age" with something like B-29s or B-52s. You already have an experience.
