I think that after world war 1, the big three were way to harsh to germany. first of all germany wasn't invited to peace talks that involved them. The reparations they had to pay were so high that they finished paying it in 2010. They lost all of their colonies, and had to take full responsibility for the war. Their navy and military forces were reduced by a huge amount. I almost felt sorry for them
The harshness to Germany was necessary. Well, close to the beginning of the war the UK warned Germany to stay out of Belgium but instead they went straight through it. After that, all the events just came down like dominoes. Also, before all of this Germany and France had some issues that later became a major cause of The World War. Since Germany was one of the major causes of the war even starting, why wouldn't even started why wouldn't you blame Germany. That country deserved what they had to pay for.
