Final answer:
President Roosevelt's leadership during WWII and his domestic policies to revive the economy were instrumental in making the U.S. a world power.
Step-by-step explanation:
President Franklin D. Roosevelt played a significant role in making the United States a world power through his leadership during World War II and his efforts to revive the American economy during the Great Depression. Under Roosevelt's direction, the U.S. emerged as a global superpower by the end of the war.
Roosevelt's foreign policy initiatives, such as the lend-lease program and the policy of good neighborliness, helped build closer ties with other nations and establish the U.S. as a major player in international affairs. His leadership during the war also elevated the United States' status as a military and economic powerhouse, ultimately setting the stage for its emergence as a world power.
In addition, Roosevelt's New Deal policies, which included government intervention to stimulate the economy and provide relief to those affected by the Great Depression, helped restore the country's economic strength and resilience. By implementing reforms and programs such as the Works Progress Administration and Social Security, Roosevelt laid the foundation for a stronger and more prosperous America, making it a force to be reckoned with on the global stage.
