How the ALLIES Won World War II [APUSH Review]

Overview of US Military Operations in World War II

Purpose of American Involvement

• The American consciousness during WWII was driven by a righteous purpose: to protect freedom and democracy against fascism and authoritarianism.

• Franklin Roosevelt's "Four Freedoms" speech outlined essential freedoms: speech, worship, want, and fear, forming the ideological basis for US involvement.

• The attack on Pearl Harbor galvanized Americans to fight for these freedoms, transitioning from neutrality to active participation.

Atrocities Revealed Post-War

• Japanese forces captured over 50,000 American POWs, subjecting them to brutal conditions that led to thousands of deaths.

• The Holocaust exemplified extreme nationalism under Hitler, targeting Jews and other groups through industrialized extermination methods.

• Approximately 6 million Jews were killed in concentration camps like Auschwitz; this revelation justified America's war efforts as righteous.

Factors Contributing to Allied Victory

Industrial Contribution

• The Allies' victory heavily relied on the industrial output of the United States; Stalin acknowledged this at the Tehran Conference.

Technological Advances

• Charles Drew revolutionized blood transfusion techniques, enabling large-scale blood banks that saved countless lives during the war.

• Aerial bombing technology improved significantly with innovations like the Norden bomb site, enhancing bombing accuracy against enemy infrastructure.

Strategic Military Campaigns

• D-Day (Operation Overlord): A massive amphibious assault in Normandy that established a crucial beachhead for further advances into Europe.

• Island Hopping Campaign: Led by General Douglas MacArthur in the Pacific, capturing lightly defended islands expedited assaults on Japan's mainland.

Use of Atomic Bomb

• The atomic bomb developed under the Manhattan Project was used after Japan refused surrender terms; bombs dropped on Hiroshima and Nagasaki resulted in immense destruction.

• Debates arose regarding the morality of using atomic bombs due to civilian casualties versus saving American soldiers from a ground invasion.

Contributions of Women and Minorities

Women's Roles

• About 10,000 women served as codebreakers during WWII; their contributions challenged gender stereotypes and laid groundwork for future equality movements.

Minority Contributions

• The Tuskegee Airmen distinguished themselves as an all-black air combat unit despite segregation; they played a significant role in changing perceptions about minorities' capabilities.

America's Role in Post-War Peace

Promoting Democracy

• The US advocated for expanded democracy in post-war Europe through discussions among the "Big Three" (US, UK, USSR), leading to agreements on joint occupation of Germany.

Financial Investment

• With minimal damage at home compared to Europe and Asia's devastation, America led reconstruction efforts via initiatives like the Marshall Plan while promoting economic stability globally.

Establishment of United Nations

• The US played a key role in creating the UN as an international peacekeeping body with veto power over global policies benefiting its interests.
