It would be a good thing if true, however this is just more Russian propaganda / justification for seizing the entire Ukraine.
I don’t think Russia has any desire to seize and occupy the entirety of Ukraine, but only the eastern part. The west of Ukraine is more naturally aligned with Poland and would be a hostile captive, so it would be better left alone. On the other hand, the eastern part of Ukraine leans toward Russia, would easily assimilate, and would provide the non-hostile land bridge to Crimea and the Black Sea that Russia so desperately needs. I expect an east-west division of Ukraine will occur, and that it will provide Kiev with more stability than the present demographic time bomb. The only reason for Russia to invade the whole of Ukraine would be to prevent Kiev from joining NATO.
