Which aspect of Woodrow Wilson and Fourteen Points was not adopted by the Paris Peace Conference?

One significant aspect of Woodrow Wilson's Fourteen Points that was not adopted at the Paris Peace Conference was the principle of self-determination for all nations. While the conference focused on establishing new national borders and mandates in Europe, the idea of allowing all ethnic groups to freely determine their own political status was largely overlooked, leading to the imposition of boundaries that often ignored the complex ethnic compositions of the regions. Additionally, Wilson's proposal for the League of Nations faced resistance, resulting in a weaker version than he envisioned.
