1945-1949

1945-1946: Creation of Eastern European People's Republics
Between November 1945 and December 1946, a number of the coalition governments established in the Eastern European countries occupied by Soviet troops during the war transformed into Communist "People's Republics" with strong ties to the Soviet Union. These included Yugoslavia (November 1945); Albania (January 1946); and Bulgaria (December 1946). The United States and Britain considered this an abrogation of agreements made at the Yalta Conference.

February 1946: George Kennan's Long Telegram and the Policy of Containment
On February 22, 1946, George F. Kennan, the Charg� d'Affaires at the Moscow Embassy, sent a long telegram to the Department of State detailing his concerns about Soviet expansionism. Kennan argued that the United States would never be able to cooperate successfully with the Soviets, because they saw the West as an enemy and would engage in a protracted battle to limit Western power and increase Soviet domination. Kennan argued that the United States should lead the West in "containing" the Soviets by exerting counterforce at various geographical and political points of conflict. Kennan published a public version of this argument in the July 1947 issue of the journal Foreign Affairs. Kennan's articulations of the policy of containment had a major influence on American foreign policy toward the Soviet Union.

March 1946: Churchill's Iron Curtain Speech
During a speech at Fulton, Missouri, on March 5, 1946, visiting British Prime Minister Winston Churchill proclaimed that Europe was divided by an "Iron Curtain" as the nations of Eastern Europe fell increasingly under Soviet control. Yugoslavia, Albania, Bulgaria, Poland, Hungary, and Czechoslovakia all fell under Communist control by early 1948.

Spring 1946: Soviet Troops in Iran
Responding to Iranian requests to the United Nations, on March 5, 1946, the United States sent a note to Moscow protesting the retention of Soviet troops in Iran, where Stalin wanted to establish Soviet influence. On April 3, the Soviet Union announced that its troops would leave by May 6.

March 1947: Truman Doctrine
The Soviets aimed also to establish influence over Turkey and Greece in an effort to seek access to the Mediterranean. President Truman delivered a speech before Congress on March 12, 1947, asking for $400 million to provide assistance for Greece and Turkey in the hopes of bolstering pro-Western governments there. In this speech, he enunciated the Truman Doctrine that would serve to justify the U.S. Cold War policy of containment. This doctrine described the U.S. policy of supporting free peoples who resisted subjugation from armed minorities or outside pressures.

June 1947: U.S. Efforts to Control Atomic Energy
In June 1947, the United States submitted proposals, know as the Baruch Plan, for the creation of an International Atomic Energy Development Authority to control all phases of the development and use of atomic energy. The United States offered to destroy its atomic weapons after international control and inspection became effective. The Soviet Union rejected the proposal.

June 5, 1947: Marshall's Offer of Economic Assistance
In a speech given at Harvard University on June 5, 1947, Secretary of State George C. Marshall offered U.S. assistance for the postwar economic rehabilitation of all European nations, including those that had adopted Communist governments. The Soviet Union denounced the Marshall Plan, saying it would infringe upon European sovereignty. Western European nations accepted Marshall's offer, while the Eastern European states followed Moscow's lead.

1948-1949: Berlin Airlift
In the summer of 1948, the Soviet Union cut off access to the Western sectors of Berlin, situated in the Soviet occupation zone of Germany. The Western powers organized a massive airlift to supply West Berlin, and organized a counter-blockade of the Soviet zone. On May 12, 1949, the Soviets lifted their blockade.

April 1949: North Atlantic Treaty Organization
On April 14, 1949, twelve Western nations signed the North Atlantic Treaty providing for mutual support in the event of a military attack on any of the parties to the treaty and established the North Atlantic Treaty Organization (NATO). The original members of NATO were Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom, and the United States.

September-October 1949: Creation of the two Germanys
Recognizing that the Soviets would not honor agreements to reunite the German zones of occupation, the Western powers moved in the fall of 1949 to establish the Federal Republic of Germany out of the Western zones of occupation. The Soviets countered by supporting the creation of the German Democratic Republic in their zone. Berlin remained divided.

September 1949: Soviet Atomic Bomb
On September 22, 1949, President Truman announced that the Soviet Union had detonated its first atomic bomb.

1950-1959

February 1950: Sino-Soviet Treaty
Despite U.S. efforts, mainland China became a Communist People's Republic. The Soviets and the Chinese signed a Sino-Soviet Treaty of Friendship on February 14, 1950.

April 1950: NSC-68
In April 1950, Truman signed National Security Council Paper 68 (NSC-68) outlining U.S. justifications for a rapid and massive U.S. military build-up. NSC-68 cited Soviet consolidation of power in Eastern Europe, Soviet expansionist tendencies, and the need for the West to contain the Soviet Union as the justifications for the United States to pursue a significant buildup of its conventional military and nuclear resources.

1950-1953: Korean War
Following World War II, the United States administered the southern occupation zone in Korea, while the Soviets administered the northern zone. Plans to unify the two zones never materialized. On June 25, 1950, North Korean forces crossed the 38th parallel into South Korea. U.S.-led United Nations forces responded, and battled the North Korean and Communist Chinese armies. The Soviet Union supplied North Korea and China. On July 27, 1953, the warring parties concluded an armistice that restored the 38th parallel, but failed to unite North and South Korea.

November 1952: U.S. Hydrogen Bomb
On November 1, 1952, the United States announced it had successfully detonated a hydrogen bomb.

March 1953: Stalin's Death
The Soviet Union's hard-line leader, Joseph Stalin, died on March 5, 1953, and the Soviet Union entered a period of collective leadership under which a handful of leaders from within the Presidium of the Communist Party shared leadership responsibilities. First Secretary of the Communist Party, Nikita Khrushchev, ultimately consolidated power and became the de facto leader of the Soviet Union.

August 1953: Soviet Hydrogen Bomb
On August 8, 1953, the Soviet Union announced it had hydrogen bomb capabilities.

August 1954: Atomic Energy Act
President Dwight D. Eisenhower signed the Atomic Energy Act in August 1954 to authorize the international exchange of information on the peaceful uses of atomic energy, and endorsed the development of commercial nuclear power.

May 1955: Creation of the Warsaw Pact
In response to NATO actions in the West, including the rearming of West Germany and the expansion of the treaty organization, on May 1, 1955, the Soviet Union concluded a military defensive alliance known as the Warsaw Pact with Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, and Romania.

May 1955: Austrian State Treaty
The United States, the Soviet Union, the United Kingdom, and France signed the Austrian State Treaty on May 15, 1955. This officially ended the four-power occupation of Austria and enabled the Austrians, who had pledged to remain neutral, to receive diplomatic recognition as an independent nation.

July 1955: Big Four Geneva Summit
Eisenhower met with Soviet Premier Nicolai Bulganin, British Prime Minister Anthony Eden, and French Premier Edgar Faure at a summit in Geneva in July 1955. Eisenhower offered an "Open Skies" proposal, calling for a U.S.-Soviet exchange of military blueprints and mutual aerial inspection of one another's military installations. The participants also discussed disarmament, German reunification through free elections, European security, and the need for East-West cultural and scientific exchange.

February 1956: Twentieth Congress of Soviet Communist Party
At the Twentieth Party Congress of the Soviet Communist Party in February 1956, Soviet leader Nikita Khrushchev publicly denounced aspects of Stalin's regime, including Stalin's harsh political purges and his "cult of personality." Khrushchev also reversed Stalinist policy by urging "the peaceful coexistence between states with differing political and social systems." This marked the beginning of a brief loosening of the most stringent forms of censorship in the Soviet Union.

June 1956: Polish Uprising
Riots against the Communist regime in Poland broke out at Poznan in June 1956, after workers demonstrated for better social and economic conditions. The revolt led the Polish Communist leadership to allow some reforms.

Autumn 1956: Suez Crisis
After the United States reneged on a deal to finance the building of the Aswan Dam, Egypt seized and nationalized the Suez Canal, through which the West received its oil supplies. This led to Israeli, British, and French military action against an Egyptian military supplied by the Soviets in the fall of 1956. While Western Europe focused on the Middle East, the Soviets moved to squash anti-communist rebellions in Poland and Hungary. Eisenhower, fearing that the Soviets would provide large-scale assistance to Egypt, convinced Britain, France, and Israel to retreat.

October-November 1956: Hungarian Uprising
Anti-Soviet popular uprisings began in Budapest and spread throughout Hungary in the autumn of 1956. On November 2, Hungarian Premier Imre Nagy, who had already promised the Hungarians free elections, denounced the Warsaw Pact and asked for United Nations support. On November 4, Soviet forces moved into Hungary and suppressed the revolt. The United States sponsored UN resolutions condemning the Soviet invasion, and called for the immediate withdrawal of Soviet troops. The U.S. Government also took measures to assist the many refugees who fled Hungary following the invasion.

1957-1958: Sputnik and the Space Race
On October 5, 1957, the Soviets beat the United States into space by successfully launching the first man-made earth satellite, Sputnik I, into orbit. A month later, the Soviets sent up another satellite, this time carrying a dog. The United States did not launch its first satellite, Explorer I, until January 31, 1958. U.S. politicians warned of the dangers of Soviet superiority in technology and science, and speculated that the Soviets might possess superior missile stockpiles.

1958: Suspension of Nuclear Tests
Soviet Foreign Minister Andrei Gromyko announced the suspension of Soviet nuclear weapons tests on March 31, 1958. On October 25, the United States and Great Britain agreed to suspend nuclear weapons testing for one year. Three-power talks on a more permanent ban of nuclear testing began at Geneva on October 31.

November 1958: Khrushchev's Berlin Demands
Motivated by fears that the West planned to arm West Germany with nuclear weapons, in November 1958, Khrushchev demanded the termination of the four-power occupation of Berlin. The Soviets also threatened to conclude a separate peace treaty with East Germany, giving Soviets control over access to Berlin, unless negotiations began within 6 months.

September 1959: Khrushchev Visits the United States
Following brief meetings with Eisenhower upon his arrival in Washington on September 15, 1959, Khrushchev embarked on a 10-day trip to New York, Los Angeles, San Francisco, farm communities in Iowa, and Pittsburgh, arranged to acquaint him with the American way of life. Eisenhower and Khrushchev then engaged in substantive talks for 2 days at Camp David. Khrushchev also visited Eisenhower's farm at Gettysburg. Just before he left, Khrushchev addressed the American people on national television. This was first visit to the United States of a Soviet leader since the establishment of U.S.-Soviet relations in 1933.

September 1959: Khrushchev-Eisenhower Meeting at Camp David
Khrushchev met with President Eisenhower at Camp David, on September 26-27, 1959. The two leaders agreed to expand exchanges and to remove the Soviet deadline for a Berlin settlement, but no progress was made on disarmament or the reunification of Germany. They agreed to meet again at a four-power summit in Paris in May 1960.

December 1959: Antarctic Treaty
On December 1, the United States, the Soviet Union, and ten other countries signed a treaty to internationalize and demilitarize the Antarctic continent.

1960-1969

May 1960: The U-2 Incident
On May 1, 1960, the Soviets shot down an American U-2 reconnaissance jet flying over Soviet territory. Since June 1956, Eisenhower had approved secret overflights of Soviet territory, and gained valuable proof that the Soviets had not gained missile superiority over the Americans. Not knowing that the Soviets had captured the pilot and gotten a confession confirming the spy mission, Eisenhower claimed the aircraft was merely a weather plane. Khrushchev presented the pilot as proof that the American President had lied.

May 1960: Paris Summit
Eisenhower, Khrushchev, British Prime Minister Harold MacMillan, and French President Charles de Gaulle met from May 16-17, 1960, in Paris. However, the meetings collapsed when Khrushchev walked out after Eisenhower refused to apologize for the U-2 incident.

May 1960: United States Unveils "Great Seal Bug" at the United Nations
On May 26, 1960, U.S. Ambassador to the United Nations Henry Cabot Lodge, Jr. unveiled the Great Seal Bug before the UN Security Council to counter Soviet denunciations of American U-2 espionage. The Soviets had presented a replica of the Great Seal of the United States as a gift to Ambassador Averell Harriman in 1946. The gift hung in the U.S. Embassy for many years, until in 1952, during George F. Kennan's ambassadorship, U.S. security personnel discovered the listening device embedded inside the Great Seal. Lodge's unveiling of this Great Seal before the Security Council in 1960 provided proof that the Soviets also spied on the Americans, and undercut a Soviet resolution before the Security Council denouncing the United States for its U-2 espionage missions.

June 1961: Vienna Meeting
President John F. Kennedy and Khrushchev met in Vienna in June 1961, primarily to discuss the status of Berlin. Other topics of discussion included the conflict in Laos and disarmament. The leaders were unable to resolve the most vexing questions pertaining to Berlin, but agreed that further discussions on Laos should be continued at the Foreign Minister level.

Summer 1961: Berlin Crisis
In July 1961, the Soviets threatened to take decisive action on Berlin. Kennedy warned that the United States would not tolerate any changes in Berlin's status. He activated 150,000 reservists, and advised the American people of the danger of an attack, possibly even a nuclear attack. Both leaders announced an increase in their defense expenditures. East Germans fled in large numbers to West Germany. On August 13, Khrushchev sealed off East Berlin from the West by erecting the Berlin Wall on Soviet-controlled territory.

October 18-29, 1962: Cuban Missile Crisis
After receiving intelligence that the Soviet Union was placing medium-range ballistic nuclear missiles in Cuba, on October 14, 1962, President Kennedy announced a naval quarantine of Cuba to block further Soviet missile deliveries, and demanded the removal or dismantling of the missiles already in Cuba. On October 28, Khrushchev agreed to stop work on the Cuban missile sites and to remove the missiles that were already in place. In return, the United States pledged not to follow through on its threat to invade Cuba.

June 1963: Establishment of the "Hotline"
The United States and the Soviet Union signed a memorandum of understanding in Geneva in June 1963 to establish a direct communications link, or "hotline," between the two governments for use in a crisis.

June 1967: Johnson and Kosygin Meeting
Following Kosygin's visit to the United Nations, where he supported the Arab nations' proposals for ending the Middle East conflict in the aftermath of the June 1967 Arab-Israeli war, Johnson met with him in Glassboro, New Jersey that same month. The leaders discussed the Middle East, disarmament, and the Vietnam War. During the conference, the Soviet Union served as intermediary in conveying North Vietnamese willingness to negotiate in exchange for a halt to the U.S. bombing.

July 1968: Nuclear Nonproliferation Treaty
On July 1, 1968, sixty-two nations, including the United States, the Soviet Union, and the United Kingdom, signed the Nuclear Nonproliferation Treaty, designed to prevent the spread of nuclear weapons and encourage the peaceful uses of atomic energy.

August 1968: Soviet Invasion of Czechoslovakia
Soviet, Polish, East German, Bulgarian, and Hungarian troops invaded Czechoslovakia on August 20, 1968, and deposed the reformist government of Alexander Dubcek, who had begun a program of economic and political liberalization (the "Prague spring"). The United States co-sponsored a UN Security Council resolution condemning the invasion and calling for the prompt withdrawal of Warsaw Pact forces; it also suspended a number of U.S.-Soviet exchange agreements and delayed ratification of the Nuclear Nonproliferation Treaty. Brezhnev later justified the invasion with the assertion, known as the Brezhnev Doctrine, that when internal or external forces hostile to socialism sought to restore the capitalist order in any socialist state, all other socialist states had the right to intervene.

November 1969: Strategic Arms Limitation Talks
The United States and the Soviet Union held preliminary Strategic Arms Limitation Talks (SALT) in Helsinki on November 17, 1969. Formal SALT negotiations began in Vienna on April 16, 1970.

September-October 1969: Soviet Submarine Base in Cuba
In the fall of 1969, the United States protested the arrival of a Soviet flotilla and the construction of a Soviet submarine base at Cayo Alcatraz in the Bay of Cienfuegos, Cuba. After several diplomatic exchanges, Soviet Ambassador Anatoliy Dobrynin reaffirmed the 1962 understanding that Soviet offensive weapons would not be stationed in Cuba.

1970-1979

February 1971: Nuclear Weapons Ban on Seabed

September 1971: Quadripartite Agreement on Berlin
The United States, the Soviet Union, France, and Great Britain signed the Quadripartite Agreement on Berlin on September 3, 1971. They agreed to improvements in the Berlin situation, including unhindered movement of people and goods between the Western Sectors of Berlin and the Federal Republic of Germany.

September 1971: Agreement to Reduce Risk of Nuclear War
The United States and the Soviet Union signed an Agreement on Measures to Reduce the Risk of Outbreak of Nuclear War on September 30, 1971. It provided for nuclear safeguards, immediate notification of an unexplained nuclear detonation, and advance notice of missile launches. They also agreed to improve the hotline.

May 1972: Moscow Summit
President Richard M. Nixon, the first U.S. President to travel to Moscow, met with Brezhnev on May 22-30, 1972. The leaders signed the Anti-Ballistic Missile (ABM) Treaty and the Strategic Arms Limitation Treaty (SALT I) Interim Agreement, both of which had been in negotiation in Helsinki and Vienna for many months. Nixon and Brezhnev also concluded agreements on public health; environmental cooperation; incidents at sea; exchanges in science, technology, education and culture; and a Declaration of Basic Principles of Mutual Relations.

June 1973: Brezhnev-Nixon Meeting in the United States
Brezhnev's visit to the United States resulted in 47 hours of meetings with Nixon in Washington, Camp David, and San Clemente from June 18-24, 1973. The two leaders signed nine accords, including an Agreement on the Prevention of Nuclear War and an Agreement on Basic Principles of Negotiations on the Further Limitation of Strategic Offensive Arms. Other agreements signed at the summit dealt with scientific cooperation, agriculture, trade, and other bilateral issues. The joint communiqu� expressed "deep satisfaction" with the conclusion of the Paris Agreement on Vietnam, which had been signed the preceding January.

October 1973: Force Reduction Meeting in Vienna
The United States, the Soviet Union, and other NATO and Warsaw Pact nations met in Vienna in October 1973 to begin Mutual and Balanced Force Reduction (MBFR) negotiations to reduce conventional forces in Europe to equal and lower levels.

June-July 1974: Moscow Summit
The Watergate scandal and the President Nixon's imminent resignation overshadowed the Moscow Summit meeting in June and July, 1974, and limited expectations on both sides. Nixon and Brezhnev discussed arms control and several international and bilateral issues. They signed a protocol limiting each side to one ABM site apiece, instead of the two allowed in the 1972 ABM Treaty, and a Threshold Test Ban Treaty that limited the size of underground nuclear weapons tests. The United States never ratified the Test Ban Treaty because of concerns about its verifiability. The governments signed several other instruments addressing scientific cooperation, cultural exchanges, and other bilateral matters. Nixon and Brezhnev also agreed to explore the possibility of a 10-year time period for a SALT treaty, which opened the way for the Vladivostok accord a few months later. The communiqu� reaffirmed an agreement to hold regular meetings.

November 1974: Vladivostok Meeting
Discussions between President Gerald R. Ford and Brezhnev on November 23 and 24, 1974, focused on strategic arms limitations as well as on a number of bilateral and international issues, including the Conference on Security and Cooperation in Europe (CSCE) and the Middle East. Ford and Brezhnev issued a joint statement on strategic offensive arms (the Vladivostok Agreement) and a joint communiqu� calling for continuing efforts at arms limitation and the development of economic cooperation. The Vladivostok accord provided some of the basic elements of the SALT II Treaty.

December 1974: Jackson-Vanik Amendment
The U.S. Congress passed the Jackson‑Vanik Amendment to the Trade Reform Act, in December 1974. This made granting the Soviet Union non-discriminatory trade status contingent upon liberalized emigration.

July 1975: Apollo-Soyuz Mission
The United States and the Soviet Union conducted the Apollo-Soyuz Test Project, a joint space effort culminating with a linking of the two crafts, in July 1975.

July-August 1975: Helsinki CSCE Meetings
In July and August 1975, during two sessions in Helsinki, immediately prior to and following the Conference on Security and Cooperation in Europe, Ford and Brezhnev attempted unsuccessfully to reach further agreement on strategic arms limitation. Differences between the two governments over cruise missiles and the Soviet Backfire bomber frustrated Ford's desires to strengthen cooperation between the two superpowers and to conclude a SALT II agreement. Ford and Brezhnev held discussions on other issues, including the Arab-Israeli conflict and the relationship between Soviet emigration policy and most-favored-nation trading status.

June 1979: SALT II Agreements
President Jimmy Carter and Brezhnev signed the SALT II Treaty at a summit in Vienna in June 1979. Carter and Brezhnev also discussed other arms control questions, including the continuation of the SALT process. They had wide‑ranging exchanges on human rights and trade, the Middle East, Afghanistan, Africa, China, and other regional issues. The two leaders also issued a joint statement of principles and basic guidelines for subsequent negotiations on the limitation of strategic arms. The United States never ratified the SALT II Treaty.

December 1979: NATO Action Against Soviet SS-20 Deployments
On December 20, 1979, NATO unanimously adopted a dual track strategy to counter Soviet SS-20 missile deployments, which became operational in 1977. The strategy called for arms negotiations with the Soviet Union to restore the Intermediate-Range Nuclear Forces (INF) balance at the lowest possible level, and the modernization of NATO INF forces through the deployment of ground-launched cruise missiles and Pershing IIs beginning in December 1983.

December 1979: Soviet Invasion of Afghanistan
The Soviet Union invaded Afghanistan on December 26, 1979. The United States immediately condemned the action, and President Carter asked the Senate to delay consideration of SALT II. Washington's responses to the invasion included deferral of most cultural and economic exchanges, cancellation of export licenses for high technology items, restriction of Soviet fishing rights in U.S. waters, suspension of grain exports, and a boycott of the 1980 Moscow Olympics.

March 1983: Announcement of Strategic Defense Initiative
In a national address on March 23, 1983, President Reagan announced his intention to commit the United States to a research program called the Strategic Defense Initiative (SDI) to study the feasibility of defensive measures against nuclear missiles. Its stated purpose was to maintain the peace rather than rely solely on the threat of retaliation and the fear of mutual destruction.

March 1983: INF Talks
On March 29, 1983, the United States proposed an Interim Agreement whereby NATO would reduce its planned deployment of longer-range INF (LRINF) missiles to a level between zero and 572, if the Soviets cut their worldwide deployment of LRINF missiles to an equal level. The U.S. delegation presented a draft treaty embodying this proposal on May 19.

April 1983: Lifting of Grain Negotiations Ban

This unfortunate incident was part of discussions between U.S. Secretary of State George Shultz and Soviet Foreign Minister Gromyko at their meetings at the Madrid Conference on Security and Cooperation in Europe seven days later.

September 1983: INF Talks
At the INF talks in September 1983, the United States submitted three new elements to its proposed interim agreement, in which it (1) would not offset all Soviet global LRINF deployments with U.S. deployments in Europe (it would retain the right, however, to deploy elsewhere to reach an equal global ceiling); (2) would be prepared to apportion the reductions of Pershing II and ground-launched cruise missiles in an appropriate manner; and (3) would consider proposals involving land-based aircraft.
