Putin has mocked this idea, because it really is stupid. Russia of all countries doesn't need more acreage. What is does need is security against hostile and aggressive armies on its borders. The anti-democracy coup in Ukraine in 2014 showed the NATO aggressors would not be stopped by political appeasement.
Do you mean the one where the people rejected a Russian front-man and then he resigned and ran home to Russia?
What about the elections after that? You seem to have forgotten about the fact that the Ukrainian people voted democratically and selected their leadership.
