The Cold War was a period of international geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc. It began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.
After the end of the Second World War in 1945, during which the US and USSR had been allies, the USSR installed satellite governments in its occupied territories in Eastern Europe and North Korea by 1949, resulting in the political division of Europe (and Germany) by an "Iron Curtain". The USSR tested its first nuclear weapon in 1949, four years after the US used its own on Hiroshima and Nagasaki, and allied with the People's Republic of China, founded in 1949. The US declared the Truman Doctrine of "containment" of communism in 1947, launched the Marshall Plan in 1948 to assist Western Europe's economic recovery, and founded the NATO military alliance in 1949 (matched by the Soviet-led Warsaw Pact in 1955). The Berlin Blockade of 1948 to 1949 was an early confrontation, as was the Korean War of 1950 to 1953, which ended in a stalemate.
US involvement in regime change during the Cold War included support for First World anti-communist and right-wing dictatorships and uprisings, while Soviet involvement included the funding of Second World left-wing parties, wars of independence, and dictatorships. As nearly all the colonial states underwent decolonization, many became Third World battlefields of the Cold War. Both powers used economic aid in an attempt to win the loyalty of non-aligned countries. The Cuban Revolution of 1959 installed the first communist regime in the Western Hemisphere, and in 1962, the Cuban Missile Crisis began after deployments of US missiles in Europe and Soviet missiles in Cuba; it is widely considered the closest the Cold War came to escalating into nuclear war. Another major proxy conflict was the Vietnam War of 1955 to 1975, which ended in defeat for the US.
The USSR solidified its domination of Eastern Europe with its crushing of the Hungarian Revolution in 1956 and the Warsaw Pact invasion of Czechoslovakia in 1968. Relations between the USSR and China broke down by 1961, with the Sino-Soviet split bringing the two states to the brink of war amid a border conflict in 1969. In 1972, the US initiated diplomatic contacts with China and the US and USSR signed a series of treaties limiting their nuclear arsenals during a period known as détente. In 1979, the toppling of US-allied governments in Iran and Nicaragua and the outbreak of the Soviet–Afghan War again raised tensions. In 1985, Mikhail Gorbachev became leader of the USSR and expanded political freedoms, which contributed to the revolutions of 1989 in the Eastern Bloc and the collapse of the USSR in 1991, ending the Cold War.
Terminology
Writer George Orwell used cold war, as a general term, in his essay "You and the Atomic Bomb", published 19 October 1945. Contemplating a world living in the shadow of the threat of nuclear warfare, Orwell looked at James Burnham's predictions of a polarized world, writing:
Looking at the world as a whole, the drift for many decades has been not towards anarchy but towards the reimposition of slavery... James Burnham's theory has been much discussed, but few people have yet considered its ideological implications—that is, the kind of world-view, the kind of beliefs, and the social structure that would probably prevail in a state which was at once unconquerable and in a permanent state of "cold war" with its neighbours.
In The Observer of 10 March 1946, Orwell wrote, "after the Moscow conference last December, Russia began to make a 'cold war' on Britain and the British Empire."
The first use of the term to describe the specific post-war geopolitical confrontation between the Soviet Union and the United States came in a speech by Bernard Baruch, an influential advisor to Democratic presidents, on 16 April 1947. The speech, written by journalist Herbert Bayard Swope, proclaimed, "we are today in the midst of a cold war." Newspaper columnist Walter Lippmann gave the term wide currency with his book The Cold War. When asked in 1947 about the source of the term, Lippmann traced it to a French term from the 1930s, la guerre froide.
Background and periodization
The United States and its Western European allies sought to strengthen their bonds and used the policy of containment against Soviet influence; they accomplished this most notably through the formation of NATO, which was essentially a defensive agreement in 1949. The Soviet Union countered with the Warsaw Pact in 1955, which had similar results with the Eastern Bloc. As by that time the Soviet Union already had an armed presence and political domination all over its eastern satellite states, the pact has been long considered superfluous. Although nominally a defensive alliance, the Warsaw Pact's primary function was to safeguard Soviet hegemony over its Eastern European satellites, with the pact's only direct military actions having been the invasions of its own member states to keep them from breaking away; in the 1960s, the pact evolved into a multilateral alliance, in which the non-Soviet Warsaw Pact members gained significant scope to pursue their own interests. In 1961, Soviet-allied East Germany constructed the Berlin Wall to prevent the citizens of East Berlin from fleeing to West Berlin, at the time part of United States-allied West Germany.
In 1991, the Russian Federation became the Soviet Union's successor state, while many of the other republics emerged as fully independent post-Soviet states.
Containment, Truman Doctrine, Korean War (1947–1953)
Iron Curtain, Iran, Turkey, Greece, and Poland
In February 1946, George F. Kennan's "Long Telegram" from Moscow to Washington helped to articulate the US government's increasingly hard line against the Soviets, which would become the basis for US strategy toward the Soviet Union. The telegram galvanized a policy debate that would eventually shape the Truman administration's Soviet policy. Washington's opposition to the Soviets accumulated after broken promises by Stalin and Molotov concerning Europe and Iran. Following the World War II Anglo-Soviet invasion of Iran, the country was occupied by the Red Army in the far north and the British in the south. Iran was used by the United States and British to supply the Soviet Union, and the Allies agreed to withdraw from Iran within six months after the cessation of hostilities. However, when this deadline came, the Soviets remained in Iran under the guise of the Azerbaijan People's Government and Kurdish Republic of Mahabad. On 5 March, former British prime minister Winston Churchill delivered his famous "Iron Curtain" speech (Fulton Speech) calling for an Anglo-American alliance against the Soviets, whom he accused of establishing an "iron curtain" dividing Europe.
A week later, on 13 March, Stalin responded vigorously to the speech, saying Churchill could be compared to Adolf Hitler insofar as he advocated the racial superiority of English-speaking nations so that they could satisfy their hunger for world domination, and that such a declaration was "a call for war on the USSR." The Soviet leader also dismissed the accusation that the USSR was exerting increasing control over the countries lying in its sphere. He argued that there was nothing surprising in "the fact that the Soviet Union, anxious for its future safety, [was] trying to see to it that governments loyal in their attitude to the Soviet Union should exist in these countries."
Soviet territorial demands to Turkey regarding the Dardanelles in the Turkish Straits crisis and Black Sea border disputes were also a major factor in increasing tensions. In September, the Soviet side produced the Novikov telegram, sent by the Soviet ambassador to the US but commissioned and "co-authored" by Vyacheslav Molotov; it portrayed the US as being in the grip of monopoly capitalists who were building up military capability "to prepare the conditions for winning world supremacy in a new war". On 6 September 1946, James F. Byrnes delivered a speech in Germany repudiating the Morgenthau Plan (a proposal to partition and de-industrialize post-war Germany) and warning the Soviets that the US intended to maintain a military presence in Europe indefinitely. As Byrnes stated a month later, "The nub of our program was to win the German people ... it was a battle between us and Russia over minds ..." In December, the Soviets agreed to withdraw from Iran after persistent US pressure, an early success of containment policy.
By 1947, US president Harry S. Truman was outraged by the perceived resistance of the Soviet Union to American demands in Iran, Turkey, and Greece, as well as Soviet rejection of the Baruch Plan on nuclear weapons. In February 1947, the British government announced that it could no longer afford to finance the Kingdom of Greece against the Communist-led DSE in the Greek Civil War. In the same month, Stalin conducted the rigged 1947 Polish legislative election which constituted an open breach of the Yalta Agreement. The US government responded by adopting a policy of containment, with the goal of stopping the spread of communism. Truman delivered a speech calling for the allocation of $400 million to intervene in the war and unveiled the Truman Doctrine, which framed the conflict as a contest between free peoples and totalitarian regimes. American policymakers accused the Soviet Union of conspiring against the Greek royalists in an effort to expand Soviet influence even though Stalin had told the Communist Party to cooperate with the British-backed government.
Enunciation of the Truman Doctrine marked the beginning of a US bipartisan defense and foreign policy consensus between Republicans and Democrats focused on containment and deterrence that weakened during and after the Vietnam War, but ultimately persisted thereafter. Moderate and conservative parties in Europe, as well as social democrats, gave virtually unconditional support to the Western alliance, while European and American Communists, financed by the KGB and involved in its intelligence operations, adhered to Moscow's line, although dissent began to appear after 1956. Other critiques of the consensus policy came from anti-Vietnam War activists, the Campaign for Nuclear Disarmament, and the anti-nuclear movement.
Marshall Plan, Czechoslovak coup and formation of two German states
In early 1947, France, Britain and the United States unsuccessfully attempted to reach an agreement with the Soviet Union for a plan envisioning an economically self-sufficient Germany, including a detailed accounting of the industrial plants, goods and infrastructure already taken by the Soviets. In June 1947, in accordance with the Truman Doctrine, the United States enacted the Marshall Plan, a pledge of economic assistance for all European countries willing to participate. Under the plan, which President Harry S. Truman signed on 3 April 1948, the US government gave to Western European countries over $13 billion (equivalent to $189 billion in 2016). Later, the program led to the creation of the OECD.
The plan's aim was to rebuild the democratic and economic systems of Europe and to counter perceived threats to the European balance of power, such as communist parties seizing control. The plan also stated that European prosperity was contingent upon German economic recovery. One month later, Truman signed the National Security Act of 1947, creating a unified Department of Defense, the Central Intelligence Agency (CIA), and the National Security Council (NSC). These would become the main bureaucracies for US defense policy in the Cold War.
Stalin believed economic integration with the West would allow Eastern Bloc countries to escape Soviet control, and that the US was trying to buy a pro-US re-alignment of Europe. Stalin therefore prevented Eastern Bloc nations from receiving Marshall Plan aid. The Soviet Union's alternative to the Marshall Plan, which was purported to involve Soviet subsidies and trade with central and eastern Europe, became known as the Molotov Plan (later institutionalized in January 1949 as the Council for Mutual Economic Assistance). Stalin was also fearful of a reconstituted Germany; his vision of a post-war Germany did not include the ability to rearm or pose any kind of threat to the Soviet Union.
In early 1948, Czech Communists executed a coup d'état in Czechoslovakia (resulting in the formation of the Czechoslovak Socialist Republic), the only Eastern Bloc state that the Soviets had permitted to retain democratic structures. The public brutality of the coup shocked Western powers more than any event up to that point and swept away the last vestiges of opposition to the Marshall Plan in the United States Congress.
In an immediate aftermath of the crisis, the London Six-Power Conference was held, resulting in the Soviet boycott of the Allied Control Council and its incapacitation, an event marking the beginning of the full-blown Cold War, as well as ending any hopes at the time for a single German government and leading to formation in 1949 of the Federal Republic of Germany and German Democratic Republic.
The twin policies of the Truman Doctrine and the Marshall Plan led to billions in economic and military aid for Western Europe, Greece, and Turkey. With the US assistance, the Greek military won its civil war. Under the leadership of Alcide De Gasperi the Italian Christian Democrats defeated the powerful Communist–Socialist alliance in the elections of 1948.
Outside of Europe, the United States also began to express interest in the development of many other countries, so that they would not fall under the sway of Eastern Bloc communism. In his January 1949 inaugural address, Truman declared for the first time in US history that international development would be a key part of US foreign policy. The resulting program later became known as the Point Four Program because it was the fourth point raised in his address.
Espionage
All major powers engaged in espionage, using a great variety of spies, double agents, moles, and new technologies such as the tapping of telephone cables. The Soviet KGB ("Committee for State Security"), the bureau responsible for foreign espionage and internal surveillance, was famous for its effectiveness. The most famous Soviet operation involved its atomic spies that delivered crucial information from the United States' Manhattan Project, leading the USSR to detonate its first nuclear weapon in 1949, four years after the American detonation and much sooner than expected. A massive network of informants throughout the Soviet Union was used to monitor dissent from official Soviet politics and morals. Although to an extent disinformation had always existed, the term itself was invented, and the strategy formalized by a black propaganda department of the Soviet KGB.
Based on the amount of top-secret Cold War archival information that has been released, historian Raymond L. Garthoff concludes there probably was parity in the quantity and quality of secret information obtained by each side. However, the Soviets probably had an advantage in terms of HUMINT (human intelligence or interpersonal espionage) and "sometimes in its reach into high policy circles." In terms of decisive impact, however, he concludes:
We also can now have high confidence in the judgment that there were no successful "moles" at the political decision-making level on either side. Similarly, there is no evidence, on either side, of any major political or military decision that was prematurely discovered through espionage and thwarted by the other side. There also is no evidence of any major political or military decision that was crucially influenced (much less generated) by an agent of the other side.
According to historian Robert L. Benson, "Washington's forte was 'signals' intelligence – the procurement and analysis of coded foreign messages," leading to the Venona project or Venona intercepts, which monitored the communications of Soviet intelligence agents. Moynihan wrote that the Venona project contained "overwhelming proof of the activities of Soviet spy networks in America, complete with names, dates, places, and deeds." The Venona project was kept highly secret even from policymakers until the Moynihan Commission in 1995. Despite this, the decryption project had already been betrayed and dispatched to the USSR by Kim Philby and Bill Weisband in 1946, as was discovered by the US by 1950. Nonetheless, the Soviets had to keep their discovery of the program secret, too, and continued leaking their own information, some of which was still useful to the American program. According to Moynihan, even President Truman may not have been fully informed of Venona, which may have left him unaware of the extent of Soviet espionage.
Clandestine atomic spies from the Soviet Union, who infiltrated the Manhattan Project during WWII, played a major role in increasing tensions that led to the Cold War.
In addition to usual espionage, the Western agencies paid special attention to debriefing Eastern Bloc defectors. Edward Jay Epstein describes that the CIA understood that the KGB used "provocations", or fake defections, as a trick to embarrass Western intelligence and establish Soviet double agents. As a result, from 1959 to 1973, the CIA required that East Bloc defectors went through a counterintelligence investigation before being recruited as a source of intelligence.
During the late 1970s and 1980s, the KGB perfected its use of espionage to sway and distort diplomacy. Active measures were "clandestine operations designed to further Soviet foreign policy goals," consisting of disinformation, forgeries, leaks to foreign media, and the channeling of aid to militant groups. Retired KGB Major General Oleg Kalugin described active measures as "the heart and soul of Soviet intelligence."
During the Sino-Soviet split, "spy wars" also occurred between the USSR and PRC.
Cominform and the Tito–Stalin Split
In September 1947, the Soviets created Cominform to impose orthodoxy within the international communist movement and tighten political control over Soviet satellites through coordination of communist parties in the Eastern Bloc. Cominform faced an embarrassing setback the following June, when the Tito–Stalin split obliged its members to expel Yugoslavia, which remained communist but adopted a non-aligned position and began accepting financial aid from the US.
Besides Berlin, the status of the city of Trieste was at issue. Until the break between Tito and Stalin, the Western powers and the Eastern bloc faced each other uncompromisingly. In addition to capitalism and communism, Italians and Slovenes, monarchists and republicans as well as war winners and losers often faced each other irreconcilably. The neutral buffer state Free Territory of Trieste, founded in 1947 with the United Nations, was split up and dissolved in 1954 and 1975, also because of the détente between the West and Tito.
Berlin Blockade
The US and Britain merged their western German occupation zones into "Bizone" (1 January 1947, later "Trizone" with the addition of France's zone, April 1949). As part of the economic rebuilding of Germany, in early 1948, representatives of a number of Western European governments and the United States announced an agreement for a merger of western German areas into a federal governmental system. In addition, in accordance with the Marshall Plan, they began to re-industrialize and rebuild the West German economy, including the introduction of a new Deutsche Mark currency to replace the old Reichsmark currency that the Soviets had debased. The US had secretly decided that a unified and neutral Germany was undesirable, with Walter Bedell Smith telling General Eisenhower "in spite of our announced position, we really do not want nor intend to accept German unification on any terms that the Russians might agree to, even though they seem to meet most of our requirements."
Shortly thereafter, Stalin instituted the Berlin Blockade (June 1948 – May 1949), one of the first major crises of the Cold War, preventing Western supplies from reaching West Germany's enclave of West Berlin. The United States (primarily), Britain, France, Canada, Australia, New Zealand, and several other countries began the massive "Berlin airlift", supplying West Berlin with provisions despite Soviet threats.
The Soviets mounted a public relations campaign against the policy change. Once again, the East Berlin communists attempted to disrupt the Berlin municipal elections, which were held on 5 December 1948 and produced a turnout of 86% and an overwhelming victory for the non-communist parties. The results effectively divided the city into East and West, the latter comprising US, British and French sectors. 300,000 Berliners demonstrated and urged the international airlift to continue, and US Air Force pilot Gail Halvorsen created "Operation Vittles", which supplied candy to German children. The Airlift was as much a logistical as a political and psychological success for the West; it firmly linked West Berlin to the United States. In May 1949, Stalin lifted the blockade.
In 1952, Stalin repeatedly proposed a plan to unify East and West Germany under a single government chosen in elections supervised by the United Nations, if the new Germany were to stay out of Western military alliances, but this proposal was turned down by the Western powers. Some sources dispute the sincerity of the proposal.
Beginnings of NATO and Radio Free Europe
Britain, France, the United States, Canada, and eight other Western European countries signed the North Atlantic Treaty of April 1949, establishing the North Atlantic Treaty Organization (NATO). That August, the first Soviet atomic device was detonated in Semipalatinsk, Kazakh SSR. Following Soviet refusals to participate in a German rebuilding effort set forth by western European countries in 1948, the US, Britain and France spearheaded the establishment of the Federal Republic of Germany from the three Western zones of occupation in April 1949. The Soviet Union proclaimed its zone of occupation in Germany the German Democratic Republic that October.
Media in the Eastern Bloc was an organ of the state, completely reliant on and subservient to the communist party. Radio and television organizations were state-owned, while print media was usually owned by political organizations, mostly by the local communist party. Soviet radio broadcasts used Marxist rhetoric to attack capitalism, emphasizing themes of labor exploitation, imperialism and war-mongering.
Along with the broadcasts of the BBC and the Voice of America to Central and Eastern Europe, a major propaganda effort began in 1949 was Radio Free Europe/Radio Liberty, dedicated to bringing about the peaceful demise of the communist system in the Eastern Bloc. Radio Free Europe attempted to achieve these goals by serving as a surrogate home radio station, an alternative to the controlled and party-dominated domestic press in the Soviet Bloc. Radio Free Europe was a product of some of the most prominent architects of America's early Cold War strategy, especially those who believed that the Cold War would eventually be fought by political rather than military means, such as George F. Kennan. Soviet and Eastern Bloc authorities used various methods to suppress Western broadcasts, including radio jamming.
American policymakers, including Kennan and John Foster Dulles, acknowledged that the Cold War was in its essence a war of ideas. The United States, acting through the CIA, funded a long list of projects to counter the communist appeal among intellectuals in Europe and the developing world. The CIA also covertly sponsored a domestic propaganda campaign called Crusade for Freedom.
German rearmament
The rearmament of West Germany was achieved in the early 1950s. Its main promoter was Konrad Adenauer, the chancellor of West Germany, with France the main opponent. Washington had the decisive voice. It was strongly supported by the Pentagon (the US military leadership), and weakly opposed by President Truman; the State Department was ambivalent. The outbreak of the Korean War in June 1950 changed the calculations and Washington now gave full support. That also involved naming Dwight D. Eisenhower in charge of NATO forces and sending more American troops to West Germany. There was a strong promise that West Germany would not develop nuclear weapons.
Widespread fears of another rise of German militarism necessitated the new military to operate within an alliance framework under NATO command. In 1955, Washington secured full German membership of NATO. In May 1953, Lavrentiy Beria, by then in a government post, had made an unsuccessful proposal to allow the reunification of a neutral Germany to prevent West Germany's incorporation into NATO, but his attempts were cut short after he was executed several months later during a Soviet power struggle. The events led to the establishment of the Bundeswehr, the West German military, in 1955.
Chinese Civil War, SEATO, and NSC 68
In 1949, Mao Zedong's People's Liberation Army defeated Chiang Kai-shek's United States-backed Kuomintang (KMT) Nationalist Government in China. The KMT-controlled territory was now restricted to the island of Taiwan, the nationalist government of which exists to this day. The Kremlin promptly created an alliance with the newly formed People's Republic of China. According to Norwegian historian Odd Arne Westad, the communists won the Civil War because they made fewer military mistakes than Chiang Kai-Shek made, and because in his search for a powerful centralized government, Chiang antagonized too many interest groups in China. Moreover, his party was weakened during the war against Japan. Meanwhile, the communists told different groups, such as the peasants, exactly what they wanted to hear, and they cloaked themselves under the cover of Chinese nationalism.
Confronted with the communist revolution in China and the end of the American atomic monopoly in 1949, the Truman administration quickly moved to escalate and expand its containment doctrine. In NSC 68, a secret 1950 document, the National Security Council proposed reinforcing pro-Western alliance systems and quadrupling spending on defense. Truman, under the influence of advisor Paul Nitze, saw containment as implying complete rollback of Soviet influence in all its forms.
United States officials moved to expand this version of containment into Asia, Africa, and Latin America, in order to counter revolutionary nationalist movements, often led by communist parties financed by the USSR. In this way, this US would exercise "preponderant power," oppose neutrality, and establish global hegemony. In the early 1950s (a period sometimes known as the "Pactomania"), the US formalized a series of alliances with Japan (a former WWII enemy), South Korea, Taiwan, Australia, New Zealand, Thailand, and the Philippines (notably ANZUS in 1951 and SEATO in 1954), thereby guaranteeing the United States a number of long-term military bases.
Korean War
One of the more significant examples of the implementation of containment was the United Nations US-led intervention in the Korean War. In June 1950, after years of mutual hostilities, Kim Il Sung's North Korean People's Army invaded South Korea. Stalin had been reluctant to support the invasion but ultimately sent advisers. To Stalin's surprise, the United Nations Security Council backed the defense of South Korea, although the Soviets were then boycotting meetings in protest of the fact that Taiwan (Republic of China), not the People's Republic of China, held a permanent seat on the council. A UN force of sixteen countries faced North Korea, although 40 percent of troops were South Korean, and about 50 percent were from the United States.
The US initially seemed to follow containment, only pushing back North Korea across the 38th Parallel and restoring South Korea's sovereignty while allowing North Korea's survival as a state. However, the success of the Inchon landing inspired the US/UN forces to pursue a rollback strategy instead and to overthrow communist North Korea, thereby allowing nationwide elections under UN auspices. General Douglas MacArthur then advanced into North Korea. The Chinese, fearful of a possible US invasion, sent in a large army and pushed the UN forces back below the 38th parallel. The episode was used to support the wisdom of the containment doctrine as opposed to rollback. The Communists were later pushed to roughly around the original border, with minimal changes. Among other effects, the Korean War galvanised NATO to develop a military structure. The Korean Armistice Agreement was approved in July 1953.
Nuclear arms race and escalation (1953–1962)
Khrushchev, Eisenhower, and de-Stalinization
In 1953, changes in political leadership on both sides shifted the dynamic of the Cold War. Dwight D. Eisenhower was inaugurated president that January. During the last 18 months of the Truman administration, the American defense budget had quadrupled, and Eisenhower moved to reduce military spending by a third while continuing to fight the Cold War effectively.
