If you think that propaganda is going to match the reality that Russia will have to deal with if trying to permanently occupy the Ukraine (if they can even conquer it, which they still haven’t been able to even begin to accomplish), you have gone completely off your rocker.
I guess Western part may be left alone, just heavily mauled. In the rest of the country, the insurgency was originally pro-Russian. Why should anyone miss Ukraine now? Do you realize that about 40,000 within the Russian forces are Ukrainians who hate the regime?
