It was the Treaty of Versailles which made not only WW II inevitable, but also set the stage for almost every single other war/conflict, through today! Granted, Wilson's crappy call for world wide Manifest Destiny didn't help matters any, vis-a-vis influencing people like Ho Chi Minh, who was actually in Paris at that time, working at a menial job.
A great book about all of this history is "PARIS 1919:SIX MONTHS THAT CHANGED THE WORLD", by Margaret MacMillan.
I don’t think that Versaille applied to the former Hapsburg Empire. Versaille was a treaty with Germany alone.
There were two other treaties that were for Austria and Hungary. The Treaty of Saint-Germain-en-Laye and the Treaty of Trianon.
