Final answer:
To assist the Allies during WWII, President Franklin D. Roosevelt successfully worked with Congress to amend the Neutrality Acts, leading to the Cash and Carry policy and later the Lend-Lease Act, which provided vital aid to nations fighting totalitarianism.
Step-by-step explanation:
During the 1930s, the United States, aiming to avoid foreign entanglements, enacted Neutrality Acts that restricted aid to nations at war. However, as totalitarian regimes in Europe and Asia threatened global stability, President Franklin D. Roosevelt sought ways to support allies without violating U.S. laws. In light of the escalating conflict and the need for American assistance to the Allies, President Roosevelt worked with Congress to revise the Neutrality Acts. The key revisions included the Cash and Carry policy, which allowed the sale of military supplies to belligerent nations as long as they paid cash and used their own ships to transport the goods. This policy was enacted with the hope of aiding nations like Britain and France while still maintaining U.S. neutrality.
When World War II began, President Roosevelt's administration found additional methods to provide support. One significant measure was the Lend-Lease Act of 1941, which authorized the president to transfer arms or other defense materials to any country whose defense he deemed vital to the defense of the United States. This act was pivotal in supporting the Allies prior to the full U.S. engagement in the war after the attack on Pearl Harbor. Thus, the correct answer to what President Roosevelt eventually did to provide assistance to our Allies is Option B: President Roosevelt asked Congress to amend, or change, the Neutrality Acts so that the U.S. could send help.
