The Roots of Conflict

  • Ethical Dilemma of Intervention
    • Question on personal responsibility to intervene when witnessing wrongdoing.
    • Historical context: United States faced challenges with Adolf Hitler's aggression in Europe.

Adolf Hitler's Aggression

  • Key Dates and Events

    • June 1940: German forces captured Paris, the French capital.
    • June 23, 1940: Hitler toured Paris, signaling his dominance.
  • Appeasement by Britain and France

    • Continued hopes from Britain and France that Hitler's aggression would cease.
    • Examples of appeasement actions:
    • Ignored massive military buildup in Germany.
    • Allowed troops into the Rhineland.
    • Annexed Austria (1938).
    • Permitted the annexation of the Sudetenland from Czechoslovakia (1938).
    • Post-occupation of Czechoslovakia and division of Poland led to realization that war was inevitable.

American Perspective on World Events

  • American Neutrality
    • Public sentiment against involvement in foreign wars post-World War I.
    • Many Americans, including Congress members, questioned U.S. involvement in WWI as a mistake.
    • Rising fears as Hitler invaded other nations left American neutrality under stress.
    • Discussion Question: Is U.S. neutrality at this point justified?

World War II Breaks Out

  • Invasion of Poland (September 1, 1939)

    • Hitler initiated Operation Blitzkrieg ("lightning war").
    • Combination of infantry, tanks, and aircraft overwhelmed Polish forces, leading to:
    • September 3, 1939: Britain and France declare war on Germany as Allies (following WWI’s historical alignment).
  • Fall of France (Spring 1940)

    • Rapid German invasion of Belgium, Luxembourg, and the Netherlands.
    • Dunkirk Evacuation (June 1940): 300,000 troops successfully evacuated before encirclement.
    • French military miscalculation regarding invasion route led to German forces bypassing the Maginot Line and advancing to Paris; France surrendered by June 22, 1940.

U.S. Isolationism & Neutrality Acts

  • Public Sentiment

    • Post-WWI isolationist sentiment dominated American political views.
  • Neutrality Acts (1935, 1937, 1939)

    • Aimed at keeping U.S. out of European conflicts by restricting:
    • Arms sales
    • Travel to war zones
  • Military Status

    • U.S. Army regarded as insufficiently sized (about 125,000 troops) compared to global military powers but deemed adequate for national defense.

Aiding Allies

  • Shift from Neutrality

    • President Franklin D. Roosevelt worked with Congress to amend Neutrality Acts following Poland's invasion, allowing arms sales to Britain and France.
    • New legislation required cash and self-transport for military supplies from the U.S.
  • Battle of Britain

    • German air assaults on British cities, particularly following the fall of France (from July 1940 to September 1940).
    • Royal Air Force (RAF) successfully resisted the Luftwaffe but suffered civilian casualties during the Blitz, changing the war dynamics.

Moving Towards War

  • Four Freedoms Speech (January 1941)

    • Roosevelt outlined freedoms most at risk by Axis ambitions:
    • Freedom of speech
    • Freedom of worship
    • Freedom from want
    • Freedom from fear
    • Emphasis on ramping up military production and initiating the Lend-Lease Program, allowing U.S. to support Allies without immediate repayment.
  • Atlantic Charter

    • Drafted in a meeting with Winston Churchill; a statement of shared Allied goals.

Attack on Pearl Harbor

  • Context of Japanese Expansion

    • Japan occupied French colonies in Southeast Asia post-French surrender, leading to U.S. export restrictions on vital materials.
    • Diplomatic efforts by Japan stalled as U.S. demands remained unsatisfied leading to:
    • December 7, 1941: Surprise attack on Pearl Harbor at 7:48 a.m.
    • Attack involved two waves from six aircraft carriers resulting in:
    • Major damage to the U.S. Pacific Fleet (four battleships sunk, nearly 200 aircraft destroyed).
    • Civilian and military casualties exceeded 2,400.
  • Aftermath

    • Immediate U.S. response escalated public support for war, leading to Roosevelt's declaration of war on Japan (December 8, 1941).
    • Germany and Italy declared war on the U.S. on December 11, solidifying America’s role in the conflict alongside the Allies in World War II.
