How did American foreign policy shift during the interwar period and World War II?

• A. From isolationism to active international engagement, Lend-Lease aiding Allies, and eventual full participation in World War II.
• B. From bold isolationism to rigid, ongoing isolationism with no war involvement
• C. From active imperial expansion to isolationism
• D. From neutrality to immediate formation of the United Nations

Answer: (A)

The main idea being tested is how U.S. foreign policy moved from staying out of European conflicts to actively engaging in global affairs during the interwar years and World War II. In the 1930s, the United States pursued a cautious stance and used neutrality acts to avoid entanglements, focusing on domestic recovery. As dictatorships aggression grew, policy gradually shifted toward supporting opponents of the Axis; this began with economic and military aid to Allies through programs like Lend-Lease, which helped Allied nations without full war declarations. Then, after the assault on Pearl Harbor, the United States entered the war and mobilized its economy and military, signaling a full commitment to the Allied cause and a decisive turn toward active international engagement. This progression—from limited support to active participation—also set the stage for postwar international cooperation, including the eventual creation of the United Nations, though the UN was formed after the war rather than at the outset.
