In my opinion it‘s not the question if the Treaty of Versailles was to harsh, but to get the main guilt for starting ww1. That is even today a question of interest for many Germans. For ww2 it is a clear fact that Nazi-Germany started the war, but not for ww1.
In the end I‘m glad that Germany and France are friends today. I think this close friendship is the most important part to keep peace in Europe.
