Before entering World War II, which of the following best describes the U.S. foreign policy?

The characterization of U.S. foreign policy before entering World War II as supportive of Allied nations through economic measures highlights the strategic approach taken by the United States during the late 1930s. This period was marked by the implementation of policies such as the Lend-Lease Act, which allowed the U.S. to supply Allied nations like Britain and later the Soviet Union with military equipment and supplies while still officially maintaining a stance of neutrality regarding direct military involvement.

Leading up to the war, although the United States was generally reluctant to engage in foreign conflicts and echoed sentiments of isolationism, the growing threat posed by Axis powers prompted a shift towards a more interventionist stance—primarily through economic aid. This approach aimed to bolster Allied powers without direct military engagement. The use of terms like "neutrality" and "isolationism" can be misleading, as they do not fully capture the active efforts made by the U.S. to support those fighting against fascism through economic means, even before formally entering the war.
