Short answer: This isn't Versailles. This is the Occupation of Rheinland of 1936, the Occupation of the "Protectorate of Böhmen and Mähren," and the Invasion of Poland all wrapped up into one.
Putin is Hitler - albeit with nukes - and appeasement will fail.
Taking war reparations off the table at this point in time would be ludicrous!

Forgot to mention my preferred solution: A bullet to the back of the head of Putin. Elegant and cheap!
