Which statement about U.S. diplomatic moves in the 1920s and 1930s is not accurate?

The statement regarding the U.S. ratifying the Kellogg-Briand Pact against waging war is not accurate in the context of U.S. diplomatic moves during the 1920s and 1930s. The Kellogg-Briand Pact, signed in 1928, was an international agreement in which signatory states promised not to use war for resolving conflicts. While the United States did ratify the pact, its effectiveness was limited and it did not lead to the reduction of military conflicts that occurred in later years.

In contrast, the U.S. provided substantial financial aid to nations emerging from World War I, supported the reduction or forgiveness of war debts which demonstrated a shift in the U.S. approach to economic diplomacy, and collaborated with other powers in agreements regarding naval disarmament, including the Washington Naval Treaty where major powers, including the U.S., set limits on naval armaments. These actions reflect a complex foreign policy approach, balancing isolationism with an involvement in international agreements aimed at promoting peace and stability in the post-war period.
