Which element of the Treaty of Versailles directly contradicted the principles laid out by Wilson in the Fourteen Points?

Wilson’s Fourteen Points called for “open covenants of peace, openly arrived at,” rejecting secret diplomacy. The secret European negotiations used to develop the Treaty of Versailles directly contradicted that principle. The League of Nations reflected another of Wilson’s proposals, while the military limits and Big Four negotiations were not the clearest contradiction of this specific principle.
