obvious fair and honest way to peace with Russia

Allowing Russia to expand its territory doesn't work. They took Crimea, and then kept invading.

Putin is looking for the boost in public opinion that he got from annexing Crimea. And will continue to annex his neighbours until he is shown that invasion, ethnic cleansing and annexation is not worth it.

The only solutions that will result in a lasting peace are ones that return Ukraine to the borders that are internationally recognised. This is this shape. Nothing less is viable.
