Assuming the Presidency at the depth of the Great Depression as our 32nd President (1933-1945), Franklin D. Roosevelt helped the American people regain faith in themselves. Roosevelt had pledged the United States to the “good neighbor” policy, transforming the Monroe Doctrine from a unilateral American manifesto into arrangements for mutual action against aggressors. He also sought through neutrality legislation to keep the United States out of the war in Europe, yet at the same time to strengthen nations threatened or attacked. When France fell and England came under siege in 1940, he began to send Great Britain all possible aid short of actual military involvement.
