Looks like Putin is getting Russia ready for a 'Forever War', so any idea that there will be peace or 'normalized relations' with Russia even after they are driven out of Ukraine seems...naive.
Best guess we get a new Korean DMZ-style situation along the Russian/Ukrainian/Belarusian border after the Russian's are forced out of Ukraine.
Till Putin is gone, Russia will be and remain an international pariah, and even after he's gone Russia will be paying reparations to Ukraine for decades.
