What this topic is asking
Winning the war was one thing; winning the peace was another, and here the United States turned inward. The NGSSS benchmark SS.912.A.5 wants you to analyze Wilson's Fourteen Points, the Treaty of Versailles and the League of Nations, the Senate's rejection of the treaty, and the postwar return to isolationism. This is a Reporting Category 1 topic the EOC tests with a quotation from Wilson or Lodge, a cartoon about the League, or a question about why the United States stayed out.
Wilson's Fourteen Points
The Treaty of Versailles
The treaty was far harsher than Wilson's idealistic plan, because Allied leaders wanted to punish and weaken Germany. Its severity would later feed German resentment and the rise of Hitler.
The League of Nations
The Senate debate and rejection
To take effect for the United States, the treaty needed Senate ratification. Many senators, led by Henry Cabot Lodge, feared that Article X would surrender Congress's power to declare war and entangle the United States in foreign quarrels. Some would accept the treaty with reservations, but Wilson refused to compromise and took his case to the public, collapsing on a speaking tour. In the end the Senate rejected the treaty, and the United States never joined the League of Nations. The country turned to isolationism, and the League, lacking American power, proved too weak to prevent the aggression of the 1930s.

Correct answer: membership in the League of Nations, especially Article X, might drag the United States into future foreign wars without the consent of Congress.
Markers reward connecting the rejection to fears over the League and a desire to avoid foreign entanglements (isolationism). Distractors saying the Senate wanted harsher terms on Germany, or wanted to join the League quickly, misstate the debate led by Henry Cabot Lodge.
