In fact I think it is time for a rehabilitation of the Treaty of Versailles. This especially applies to

ARTICLE 231.
The Allied and Associated Governments affirm and Germany accepts the responsibility of Germany and her allies for causing all the loss and damage to which the Allied and Associated Governments and their nationals have been subjected as a consequence of the war imposed upon them by the aggression of Germany and her allies.

My argument is that without a decisive occupation and supervised reconstruction it is to easy for these revanchist fantasies to take root.
