How did F.D.R have a impact in ww2?

Answer 1

This is a bit of a complexed question and one must start with the great depression and FDR's leadership in bringing the U.S out of it.

From a bio of FDR: Assuming the Presidency at the depth of the Great Depression, Franklin D. Roosevelt helped the American people regain faith in themselves. He brought hope as he promised prompt, vigorous action, and asserted in his Inaugural Address, "the only thing we have to fear is fear itself."

He was elected President in November 1932, to the first of four terms. By March there were 13,000,000 unemployed, and almost every bank was closed. In his first "hundred days," he proposed, and Congress enacted, a sweeping program to bring recovery to business and agriculture, relief to the unemployed and to those in danger of losing farms and homes, and reform, especially through the establishment of the Tennessee Valley Authority.

By 1935 the Nation had achieved some measure of recovery, but businessmen and bankers were turning more and more against Roosevelt's New Deal program. They feared his experiments, were appalled because he had taken the Nation off the gold standard and allowed deficits in the budget, and disliked the concessions to labor. Roosevelt responded with a new program of reform: Social Security, heavier taxes on the wealthy, new controls over banks and public utilities, and an enormous work relief program for the unemployed.

In 1936 he was re-elected by a top-heavy margin. Feeling he was armed with a popular mandate, he sought legislation to enlarge the Supreme Court, which had been invalidating key New Deal measures. Roosevelt lost the Supreme Court battle, but a revolution in constitutional law took place. Thereafter the Government could legally regulate the economy.

As to the war itself, (from his bio) 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.

When the Japanese attacked Pearl Harbor on December 7, 1941, Roosevelt directed organization of the Nation's manpower and resources for global war.

Feeling that the future peace of the world would depend upon relations between the United States and Russia, he devoted much thought to the planning of a United Nations, in which, he hoped, international difficulties could be settled.

Overall it can be said FDR's leadership rallied the nation as a whole where, unlike todays Iraq war, the Vietnam war and the Korean war, World War Two was largely a "Patriotic War." and in many ways a cultural revolution with in America itself. With the men away at war, women took on the roles of traditional male workers. They gained independence to a great deal both as bread earners and as homemakers.
