Why was Wilson unsuccessful in achieving his goal of self determination for the peoples of Europe after World War 1?

Woodrow Wilson's goal of self-determination for the peoples of Europe after World War I was largely unsuccessful due to a combination of geopolitical realities and the interests of European powers. Many leaders, particularly those of France and Britain, prioritized national security and territorial gains over Wilson's ideals, leading to compromises that undermined his vision. Additionally, the Treaty of Versailles and other agreements often imposed borders and governance that did not align with the ethnic and national identities of the affected populations, resulting in ongoing conflicts and dissatisfaction. Ultimately, Wilson's inability to enforce his principles in the face of entrenched political interests limited the realization of self-determination in the post-war landscape.
