十四か条の平和原則
The most influential man behind the propaganda in the United States was President Woodrow Wilson. In his famous January 1918 declaration, he outlined the "Fourteen Points," which he said that the United States would fight to defend. Aside from the restoration of freedom in Europe in countries that were suppressed by the power of Germany, Wilson's Fourteen Points called for transparency regarding discussion of diplomatic matters, the free navigation of the seas in peace and in war, and equal trade conditions among all nations. The Fourteen Points became very popular across Europe, and motivated German Socialists especially. It served as a blueprint for world peace to be used for peace negotiations after the war. Wilson's points inspired audiences around the world and greatly strengthened the belief that Britain, France, and America were fighting for noble goals.
