The United States' rejection of the Treaty of Versailles played a significant role in the country's return to isolationism. Senator Lodge's excerpt highlights some of the concerns that many Americans had with the treaty, particularly the fear of being dragged into future European conflicts. Lodge argued that the treaty would undermine American sovereignty and that the League of Nations, which was established by the treaty, would infringe upon America's right to self-determination. These concerns were shared by many Americans, who saw the treaty as a threat to their country's independence and sovereignty. As a result, the Senate rejected the treaty, and the United States did not join the League of Nations. This decision marked a return to isolationism, as the country focused on its own affairs and sought to avoid involvement in international conflicts. The rejection of the Treaty of Versailles and the subsequent return to isolationism had significant consequences for American foreign policy, shaping the country's approach to international affairs for decades to come.
