Cold War 1947-1991
The Cold War was the state of conflict, tension and competition that existed between the United States and the Soviet Union and their respective allies from the mid-1940s to the early 1990s. Throughout this period, rivalry between the two superpowers was expressed through military coalitions, propaganda, espionage, weapons development, industrial advances, and competitive technological development, which included the space race.
In a meeting with congressional leaders, the argument of "apples in a barrel infected by one rotten one" was used to convince them of the significance in supporting Greece and Turkey. It was to become the "domino theory." On the morning of March 12, 1947, President Harry S. Truman appeared before Congress to ask for $400 million of aid to Greece and Turkey. Calling on congressional approval for the United States to "support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures," or in short a policy of "containment," Truman articulated a presentation of the ideological struggle that became known as the "Truman Doctrine." Although based on a simplistic analysis of internal strife in Greece and Turkey, it became the single dominating influence over U.S. policy until at least the Vietnam War.
Stalin responded by blocking access to Berlin, which was deep within the Soviet zone although subject to four-power control. The Soviets cut off all rail and road routes to West Berlin. No trucks or trains were allowed entry into the city. Truman embarked on a highly visible move that would humiliate the Soviets internationally: flying supplies in over the blockade during 1948-1949. Military confrontation loomed while Truman flew supplies through East Germany into West Berlin during the 1948-1949 blockade. This costly aerial supplying of West Berlin became known as the Berlin Airlift.
After the deaths of three successive elderly Soviet leaders since 1982, the Soviet Politburo elected Gorbachev Communist Party General Secretary in March 1985, marking the rise of a new generation of leadership. Under Gorbachev, relatively young reform-oriented technocrats, who had begun their careers in the heyday of “de-Stalinization” under reformist leader Nikita Khrushchev (1953–1965), rapidly consolidated power, providing new momentum for political and economic liberalization, and the impetus for cultivating warmer relations and trade with the West.
In an attempt to halt the rapid changes to the system, a group of Soviet hard-liners represented by Vice-President Gennady Yanayev launched a coup overthrowing Gorbachev in August 1991. Russian President Boris Yeltsin rallied the people and much of the army against the coup and the effort collapsed. Although restored to power, Gorbachev’s authority had been irreparably undermined. In September, the Baltic states were granted independence. On December 1, Ukraine withdrew from the USSR. On December 31, 1991 the USSR officially dissolved, breaking up into fifteen separate nations.
