President Wilson was indeed bitterly disappointed by the outcome of the peace negotiations at Versailles as he regarded the final agreement as a bundle of compromises that significantly departed from both the letter and the spirit of his Fourteen Points.

Wilson had hoped that any agreement reached at Versailles would rebuild Europe on the basis of his Fourteen Points; however, it wasn't very long after arriving at the peace negotiations that Wilson realized that his high principles would soon collide with the cold, hard reality of international politics, thus necessitating some kind of compromise, something that the President found rather squalid.

Although Wilson obtained much of what he wanted from Versailles, any sense of achievement was blunted by what he didn't get. His prized principle of self-determination was severely compromised by the refusal of Great Britain, Belgium, and France to give freedom to their imperial subjects.

Wilson also wanted a union between Germany and Austri, but didn't get his way as such a proposal was way too controversial, not least because it was bitterly opposed by the French on strategic grounds.

Wilson's ideal of mutual cooperation was torpedoed by the Czech occupation of Teschen, a disputed territory fought over by Czechoslovakia and Poland, and by Poland's occupation of lands previously belonging to the Russian Empire.

In so many parts of Europe and the wider world, it seemed that the principles that Wilson had hoped the Versailles Treaty would embody were under attack. No wonder he was so bitterly disappointed by the outcome.
