The United States Enters the War

2. The United States Enters the War
The Main Idea
Isolationist feeling in the United States was strong in the 1930s, but Axis aggression eventually destroyed it and pushed the United States into war.
Reading Focus
Why was a commitment to isolationism so widespread in the 1930s?
How did Roosevelt balance American isolationism with the need to intervene in the war?
What did the United States do to prepare for war in 1940 and 1941?
What were the causes and effects of the Japanese attack at Pearl Harbor?

3. United States Isolationism in the 1930s
The desire to avoid involvement in foreign wars was known as isolationism. Isolationists were not necessarily pacifists. Most isolationists simply wanted to preserve America’s freedom to choose the time and place for action.
Many Americans questioned what the Allies’ costly victory in World War I had actually achieved. Anti-League of Nation feelings soared as people believed that the League might drag the United States into future wars.
Roosevelt was not an isolationist; however, he was focused on solving problems at home by implementing his New Deal programs. Congress did pass isolationist measures such as the Neutrality Act in 1935.

4. American Isolationism (02:41)

5. Isolationism versus Intervention
The Neutrality Act prohibited the sale of arms or making loans to warring countries.
Roosevelt needed the support of isolationists in Congress. They wanted to remain neutral.
The United States did not intervene in the Spanish Civil War or the Japanese invasion of China.
Intervention
When Italy invaded Ethiopia, Roosevelt stopped arms sales to both countries—which hurt only Italy.
Roosevelt did not want to remain neutral—he was worried about the aggressive actions of totalitarian leaders.
Roosevelt began to speak out against neutrality with his Quarantine Speech.

6. U.S. Reaction- Neutrality
FDR does not ask the American People to be neutral in thought and deed.
He invoked the Neutrality Act of 1937.
FDR got Congress to pass the Neutrality Act of 1939 which helped the allies by repealing the arms embargo.

7. U.S. Neutrality Acts
Tydings-McDuffie Act provided for the independence of the Philippines by 1946.
1935- FDR recommends the US join the World Court- isolationists say no.
Neutrality Acts- US citizens travel at own risk to Belligerent nations, shipment of arms barred to Spain during civil war (this helped the fascists.).
1937- Sales to belligerents, but only on “cash and carry” basis.- law embargoed munitions and possibly other exports the President saw fit.
1937 amendment would have prevented Congress from declaring war without first submitting the question to a popular vote. It was never submitted.
These laws did not block the world from going to war.

8. FDR and neutrality
FDR warned America about war and that the US could not be a mere spectator. He wanted quarantine, but did not get it
Pacifists- never go to war for any reason.
Isolationists- fence off the New World and keep the war out.
5th Columnists- German agents operating inside the United States waiting to become active.
Nazi sympathizers- Italian and German immigrants and American Nazi.
Defeatists- We can not possible defeat them. (Lindbergh)
Hate England Crowd – such as the Irish.
Business as usual- businesses profiting from the war. Arms manufacturers and bankers profit either way.
Appeasers- Give in to Hitler’s demands

9. American Isolationism
Why was a commitment to isolationism so widespread in the 1930’s?
Identify – What foreign policy matter did President Roosevelt address while he was focusing on his New Deal programs?
Evaluate – Why do you think the Neutrality Act prohibited the export of arms, ammunition, or any other tools of war to any country that was at war?

10. Balancing Isolationism and Intervention
How did Roosevelt balance American isolationism with the need to intervene in the war?
Identify – What events of the mid-1930’s led President Roosevelt to give his quarantine speech?
Analyze – Why did Roosevelt grow increasingly unwilling to allow America to remain isolationist?
Evaluate – Why do you think businesses refused Roosevelt’s request to end oil shipments to Italy?

11. The United States Prepares for War
Roosevelt asked Congress for money to build new naval vessels.
Congress approved despite isolationist complaints.
Congress changed the neutrality laws to a new policy called cash-and-carry.
Countries at war could buy American goods if they paid cash and picked up their goods at American ports.
Roosevelt urged a policy of “all aid short of war.”
He traded 50 aging warships for eight British military bases. Isolationists opposed the deal, but were too weak to stop it.

12. The United States prepares for war
U.S. needs to rearm- 50,000 planes in 1941, and every year till Nazi’s are defeated.
Billions were asked for to build a two ocean navy.
Isolationists still hoped the Neutrality Acts of 1939 would keep us out of war.

13. Destroyers for Bases Deal
To get around the laws on helping beligerents, FDR approved the selling of American military equipment to private companies the were buying for the British.
Churchill wanted U.S. destroyers to protect ships at sea and supplies.
President devised the “Destroyers for bases deal”- we transferred 50 old but useful destroyers to Great Britain in exchange for the use of 8 British naval bases in the Atlantic. Britain was to never surrender this fleet to Hitler.

14. Helping the British
England out of cash for Cash and Carry. With Neutrality law in place FDR could not help the English and they would surely lose the war.
Lend-Lease- clever plan- we would offer to lease (lend) to countries whose defense was considered vital to the defense of the U.S.
British would not need cash to get the supplies.

15. Preparing for War
Roosevelt defeated business leader Wendell Willkie for an unprecedented third term as president. He felt world events required experience in the White House.
Roosevelt wanted to make the United States an “arsenal of democracy.” Congress passed the Lend-Lease Act, which allowed the nation to send weapons to Great Britain.
Roosevelt and Winston Churchill met secretly in They agreed to the Atlantic Charter. This document proclaimed the shared goals of the United States and Britain in opposing Hitler and his Allies.
Despite German U-boat attacks on U.S. ships trying to deliver goods under the Lend-Lease Act, isolationists continued to oppose entry into the war.

16. World affairs and the presidential campaign of 1940
Wilkie vs. FDR
Wilkie opposed the New Deal, but also wanted to help Great Britain and the draft.
Wilkie became reckless in his attacks and FDR reckless in his responces about sending the boys to war.
FDR won easily but not as large as before.- but 1st president to be elected to three terms.

17. Atlantic Charter
Meeting of Churchill and FDR off Newfoundland.
Up-to-date version of Wilson’s 14 points.
