A less obvious link between the war and American policy was Wilson's hope of playing a major role in ending the war and shaping the peace settlement. Wilson, a Progressive Democrat who abhorred war as wasteful, believed in the rule of law and the poxffer of diplomacy. He also believed that the United States had a moral obligation to extend its democratic principles to the world, if not by example, then by more visible engagement in world affairs. Wilson preached an internationalism that argued that American interests were not confined to the Western Hemisphere. From 1914 onward, using Colonel House as his emissary, the American president promoted contact with the warring parties to further this goal of positioning the United States as a mediating power.
