The imperialist powers all wanted to maximize their own interests, which caused the Paris Peace Conference to fall into fierce quarrels from the beginning.

When discussing the conference proceedings, Wilson insisted on discussing the establishment of the League of Nations first. He believed that the League of Nations and the peace treaty should be a unity. The final decision on the disposal of defeated countries and the redistribution of their colonies should be made by the League of Nations. . Obviously, if the League of Nations is established first and the United States can control it, the United States can acquire some colonies through it and control international affairs through it. The United States could also cancel alliances with other countries through the League of Nations, mainly the Anglo-Japanese Alliance. Wilson said, "The League of Nations is an alliance in itself and does not need any other alliance." Therefore, Wilson repeatedly insisted on discussing the establishment of the League of Nations first, calling it "the basis of the entire diplomatic structure for achieving permanent peace."
