Final answer:
In the 1930s, the United States followed a policy of isolationism and neutrality, exemplified by the Neutrality Acts, to avoid involvement in international conflicts, particularly in Europe.
Step-by-step explanation:
U.S. Isolationism in the 1930s
In the 1930s, the United States aimed to avoid international affairs, especially those concerning European conflicts, through a policy of neutrality. Reflecting a historical precedent set by the Monroe Doctrine and Washington's Farewell Address, the U.S. adhered to isolationist principles. The passage of the Neutrality Acts of 1935, 1936, and 1937 exemplified this approach by banning arms exports and loans to warring nations. Despite these policies, there was a growing internal debate about supporting allies such as Britain and France, especially under President Franklin D. Roosevelt, who desired to aid them discreetly. This isolationist stance persisted until the more direct involvement demanded by World War II.
