The COLD WAR [APUSH Review Unit 8 Topic 2] Period 8: 1945-1980

Understanding the Cold War: 1945-1980

Introduction to the Cold War

• The video introduces Unit 8 of the AP U.S. History curriculum, focusing on the Cold War from 1945 to 1980.

• The learning objective is to explain the continuities and changes in Cold War policies during this period.

Context and Causes of the Cold War

• Post World War II, the U.S. emerged as a superpower, but tensions with the Soviet Union escalated, leading to the Cold War.

• The Cold War is defined as a conflict between two powers (U.S. and USSR) that does not involve direct military engagement but rather ideological battles.

Ideological Conflict

• Tensions date back to the Russian Revolution in 1917; communism was viewed unfavorably by the U.S., which sought a democratic capitalist world.

• Both ideologies are expansionist, aiming to reshape global governance according to their principles.

Key Events Leading to Distrust

• Mistrust grew even before WWII ended due to disagreements over post-war arrangements in Eastern Europe.

• Stalin's decision to maintain Soviet troops in Eastern European countries contradicted agreements for free elections, creating satellite states under Soviet control.

Berlin Division

• The division of Germany into occupation zones after WWII led to further tensions; Western powers aimed for a strong Germany while Soviets wanted it weak.

• Churchill famously described an "iron curtain" descending across Europe, symbolizing this political divide.

U.S. Response: Containment Strategy

• The concept of containment emerged as a primary strategy against communism; resources were allocated towards preventing its spread.

Truman Doctrine

• President Truman introduced the Truman Doctrine advocating support for nations threatened by communism, starting with $400 million in aid for Turkey and Greece.

Cold War Dynamics and Key Events

Ideological Tensions and the Berlin Blockade

• A healthy economy often leads nations to favor democracy over communism, which frustrated Stalin, particularly regarding U.S. involvement in Berlin.

• The Berlin Blockade was initiated by Stalin to prevent Western powers from accessing West Berlin, aiming to absorb it into Soviet control.

• In response, the U.S. organized the Berlin Airlift, conducting over 200,000 flights to supply West Berlin and thwart Soviet takeover.

Military Alliances and Nuclear Proliferation

• The formation of NATO marked a military alliance among member nations to counter Soviet aggression; this prompted the Soviets to create the Warsaw Pact for Eastern European communist nations.

• The arms race escalated with both superpowers stockpiling nuclear weapons after the U.S. developed its first atomic bomb in 1945 and the Soviets followed suit in 1949.

• Despite increasing arsenals of nuclear weapons, both sides recognized that using them would lead to mutual assured destruction.

Proxy Wars: Korean War Overview

• While the Cold War is often seen as an ideological battle without direct conflict, numerous proxy wars occurred where the U.S. and USSR supported opposing sides.

• The Korean War began when North Korea invaded South Korea in June 1950 using Soviet supplies; this led to UN intervention primarily by American forces under General Douglas MacArthur.

• The war ended with Korea remaining divided at the 38th parallel, illustrating it as a proxy conflict resulting from Truman's containment policy against communism.
