The United States Senate refused to ratify the

Treaty of Versailles after World War I because

many senators believed

(1) President Woodrow Wilson was too ill to sign

the treaty

(2) most Americans had sympathized with

Germany during the war

(3) the treaty would not require reparations from

Germany

(4) the League of Nations could draw the United

States into future wars

The United States Senate refused to ratify the Treaty of Versailles after World War I because many senators believed 4. the League of Nations could draw the United States into future wars. The US had only just recently begun to emerge from isolation in the Western Hemisphere and had just fought in a particularly deadly World War. As such, Senators were wary and ultimately rejected placing the nation in the League of Nations because of the fear that it would result in future conflict.
