3. Explain why President Wilson fell out with the other members of the "Big Four."

President Woodrow Wilson of the United States fell out with the other members of the "Big Four" (which included the leaders of the United Kingdom, France, and Italy) during the negotiations for the Treaty of Versailles, which ended World War I. The main reasons for this conflict were:<br /><br />1. Disagreements over the terms of the treaty: Wilson had proposed his "Fourteen Points" as a basis for peace, which emphasized principles such as self-determination, freedom of the seas, and the establishment of an international organization to prevent future wars. However, the other members of the Big Four were more interested in punishing Germany and securing their own national interests, which led to a clash over the terms of the treaty.<br /><br />2. National interests and territorial claims: The leaders of the United Kingdom, France, and Italy had their own territorial ambitions and national interests that they wanted to protect and advance. For example, the United Kingdom wanted to maintain its colonial empire, France sought to regain the territories of Alsace and Lorraine, and Italy wanted to expand its influence in the Balkans. These conflicting national interests made it difficult to reach a consensus on the terms of the treaty.<br /><br />3. Differing visions for the post-war world: Wilson's vision for the post-war world was based on his idealistic principles, such as the establishment of the League of Nations and the promotion of democracy and self-determination. However, the other members of the Big Four were more pragmatic and focused on power politics and the balance of power in Europe. This difference in vision and approach led to tensions and disagreements during the negotiations.<br /><br />In the end, Wilson's influence waned, and the other members of the Big Four were able to shape the Treaty of Versailles in a way that was more favorable to their own national interests, despite Wilson's efforts to promote his idealistic vision for the post-war world.
