Mark three ways the attitudes of the United States changed after World War I.

- Many Americans took a more global view of the role of the United States in world affairs.

- Some Americans modified their understanding of the policies and motives of European powers, particularly of allied countries.

- However, the United States returned to isolationism after the war, an attitude reflected in the refusal to join the League of Nations and ratify the Treaty of Versailles.

1. Americans lost interest in progressive causes.

2. Americans wanted to return to a normal lifestyle.

3. The question of isolationism or internationalism was a major concern for the people of America.
