What did the refusal of the US to join the League of Nations indicate?

Answer 1

The refusal of the United States to join the League of Nations indicated a significant shift toward isolationism in American foreign policy following World War I. It reflected widespread skepticism about international commitments and a desire to avoid entanglement in European conflicts. This decision also weakened the League's effectiveness, as the absence of the U.S., a major world power, undermined its authority and ability to enforce collective security measures. Ultimately, it foreshadowed the challenges the League would face in maintaining peace and stability globally.
