  • FDR's unpresidented third term

    FDR's unpresidented third term
    1940 Presidential election against republican Wendell Willkie. Roosevelt was easily elected because there was very little difference between the candadites so people went with what they were familiar with. FDR was elected partly because of his leadership that could be seen as a positive during war.
  • The Lend-lease Plan

    The Lend-lease Plan
    Britain had no more cash to spend in the arsenal of democracy. FDR tried to help by suggesting a new plan that he called a lende-lease policy. The plan stated that the president would lend or lease arms and other supplies to "any country whose defense was vital to the United States." Isolationists argued bitterly against the plan.
  • Supporting Stalin

    Supporting Stalin
    Hitler broke the agreement he made in 1939 with Stalin not to go to war and invaded the Soviet Union. FDR began sending lend-lease supplies to the Soviet Union. FDR was aiding the Soviet Union when Hitler was trying to invade and take over.
