It took 20 years for both Vietnam and Afghanistan (in the American case) to finally convince foreign occupiers to leave. Putin is very unlikely to still be alive in 20 years, so it's more a matter of convincing whoever or whatever follows that the prospect of even more decades of occupation is not worth it. It's unfortunate it takes that long for regime change to finally get over the sunk cost fallacy of the original invaders, but some sort of change will eventually come. When it happens, we'll get to find out how much Putin's cronies really agree with him versus just being afraid of publicly disagreeing as long as he is still in charge.
