Criticism of the paris peace settlement is unfair, and shows a lack of understanding of the problems facing the peacemakers in 1919-1920. how far do you agree?

This is not exactly true that it is unfair. The enemies had to be punished for all the evil deeds, but the peacemakers who were Europeans who won the war made many issues due to their behavior. For starters, they didn't even invite Germany to the table and the Germans had to accept anything that they were told to do without any negotiation. In addition, they didn't just want to punish them but rather to ensure their own political and cultural dominance over Europe. They also made the punishment much more severe, even though Wilson stated that the enemies should be punished accordingly and not just out of anger and malice.

I do not agree at all. The agreement placed the entire blame for the war on Germany when the other powers were just as responsible. The humiliation of Germany set the stage for the rise of the Nazis and an even more terrible war.
