Answer:
Throughout the 1920s and 1930s Vinson consistently called for strengthening the nation's defenses. Committed to arms reduction, the United States had agreed to the Washington Treaty of 1922 and the London Treaty of 1930, which limited the size of the naval fleets of the major powers. Vinson protested that the United States, unlike the other powers, had not even built its navy up to the level authorized by these treaties. He made little headway during the administrations of Harding, Coolidge, and Hoover, but found President Franklin Roosevelt more receptive to his arguments. In 1934 Roosevelt signed the Vinson-Trammell Act, which would bring the navy to the strength permitted by the treaties of 1922 and 1930.
