How it affect the U.S

The United States, removed by an ocean from the center of the war and joining late in the war, did not suffer the catastrophic losses of the major belligerents. U.S. losses in life were great, more than 100,000, but this was small in comparison to the millions lost by the other major powers.

Furthermore, the United States was a great continental power, with great population and resources. The war stimulated the U.S. economy, increased employment and wages, and brought great profit to industry. The United States emerged from the war as clearly the greatest power in the world as well as the creditor nation of the world.

These circumstances thrust the United States into a position as world leaders, while the American people still assumed that Europe had little to do with America. President Wilson had a vision that would have involved the United States extensively in world affairs through the League of Nations, but he was unable to find popular support.
