Woodrow Wilson was president of the United States, and he came to Europe with 14 points, 14 ideas that would avoid this situation again. One of them was the League of Nations, kind of a family of countries around the world where we could settle disputes before they got to war status. All of his other ideas were pretty much rejected, self-determination and freedom of the seas. But even Woodrow Wilson, who came up with the idea, couldn't get the United States to join the League of Nations. It was rejected by the United States Senate, and the United States retreated back to isolationism. And the League of Nations couldn't be a success really without us. So the consequence of World War I, you want an effect?
