I think Ukrainian neutrality is fine, the question is would Putin leave it at that or constantly be meddling in Ukrainian governance and just restarting this over and over. Then again, I suppose if that is his stance, there is no way out until he is gone from the scene and there will be continual tension until then. I've noted before that the Russians have been willing to leave the Finns alone - also directly on their border and with lots of strategic relevance in terms of being able to interrupt Russian access through the arctic sea. But Putin clearly has more of a hard on for Ukraine than a couple of generations of Russian leaders ever did for Scandinavia
