America Enters the War; Wilson's Plan for Peace
The entry of the United States into the First World War in April 1917 as an “associate”—not ally—of the Allies, was more than just a response to submarine warfare; it also reflected the vision of President Woodrow Wilson.
The President's plan for the future, outlined in the “Fourteen Points” (January 1918) and augmented by later pronouncements, envisioned restoration of a stable, equitable, and enduring international balance through a new collective security organization, the League of Nations, based on a consensus of the great powers. Due in large part to Wilson's vision, the United States had changed course from isolation toward engagement.
