The breakaway republics have been at war for 6 years, just occupying them wouldn't do anything for peace. If Russia wants to stop the fighting it has to end the Ukrainian military. I agree they won't look to occupy the Ukraine, that would be a major blunder. They will want peace on condition of agreements of Ukrainian de-militarisation, Ukraine to end claims to Crimea and the Donbas and for NATO membership aspirations to be squashed. If the war drags out because of continued support from the west we really will be in a very dangerous position indeed.
and when 2/3rds of the population of Ukraine want to be in NATO and with the EU, you just ignore them to allow Putin to stroke his ego and feel secure?
I see thats what HE wants, but is it the right outcome for the people of Ukraine, not in the slightest.
