What were the important Cold War events of the 1960s & 1970s?

The Cuban Missile Crisis of October 1962 was a direct and dangerous confrontation between the United States and the Soviet Union during the Cold War and was the moment when the two superpowers came closest to nuclear conflict. The crisis was unique in a number of ways, featuring calculations and miscalculations as well as direct and secret communications and miscommunications between the two sides. The dramatic crisis was also characterized by the fact that it was primarily played out at the White House and the Kremlin level with relatively little input from the respective bureaucracies typically involved in the foreign policy process.

After the failed U.S. attempt to overthrow the Castro regime in Cuba with the Bay of Pigs invasion, and while the Kennedy administration planned Operation Mongoose, in July 1962 Soviet premier Nikita Khrushchev reached a secret agreement with Cuban premier Fidel Castro to place Soviet nuclear missiles in Cuba to deter any future invasion attempt. Construction of several missile sites began in the late summer, but U.S. intelligence discovered evidence of a general Soviet arms build-up on Cuba, including Soviet IL–28 bombers, during routine surveillance flights, and on September 4, 1962, President Kennedy issued a public warning against the introduction of offensive weapons into Cuba. Despite the warning, on October 14 a U.S. U–2 aircraft took several pictures clearly showing sites for medium-range and intermediate-range ballistic nuclear missiles (MRBMs and IRBMs) under construction in Cuba. These images were processed and presented to the White House the next day, thus precipitating the onset of the Cuban Missile Crisis.

Kennedy summoned his closest advisers to consider options and direct a course of action for the United States that would resolve the crisis. Some advisers—including all the Joint Chiefs of Staff—argued for an air strike to destroy the missiles, followed by a U.S. invasion of Cuba; others favored stern warnings to Cuba and the Soviet Union. The President decided upon a middle course. On October 22, he ordered a naval “quarantine” of Cuba. The use of “quarantine” legally distinguished this action from a blockade, which assumed a state of war existed; the use of “quarantine” instead of “blockade” also enabled the United States to receive the support of the Organization of American States.

That same day, Kennedy sent a letter to Khrushchev declaring that the United States would not permit offensive weapons to be delivered to Cuba, and demanded that the Soviets dismantle the missile bases already under construction or completed, and return all offensive weapons to the U.S.S.R. The letter was the first in a series of direct and indirect communications between the White House and the Kremlin throughout the remainder of the crisis.

The President also went on national television that evening to inform the public of the developments in Cuba, his decision to initiate and enforce a “quarantine,” and the potential global consequences if the crisis continued to escalate. The tone of the President’s remarks was stern, and the message unmistakable and evocative of the Monroe Doctrine: “It shall be the policy of this nation to regard any nuclear missile launched from Cuba against any nation in the Western Hemisphere as an attack by the Soviet Union on the United States, requiring a full retaliatory response upon the Soviet Union.” The Joint Chiefs of Staff announced a military readiness status of DEFCON 3 as U.S. naval forces began implementation of the quarantine and plans accelerated for a military strike on Cuba.

On October 24, Khrushchev responded to Kennedy’s message with a statement that the U.S. “blockade” was an “act of aggression” and that Soviet ships bound for Cuba would be ordered to proceed. Nevertheless, during October 24 and 25, some ships turned back from the quarantine line; others were stopped by U.S. naval forces, but they contained no offensive weapons and so were allowed to proceed. Meanwhile, U.S. reconnaissance flights over Cuba indicated the Soviet missile sites were nearing operational readiness. With no apparent end to the crisis in sight, U.S. forces were placed at DEFCON 2—meaning war involving the Strategic Air Command was imminent. On October 26, Kennedy told his advisors it appeared that only a U.S. attack on Cuba would remove the missiles, but he insisted on giving the diplomatic channel a little more time. The crisis had reached a virtual stalemate.

That afternoon, however, the crisis took a dramatic turn. ABC News correspondent John Scali reported to the White House that he had been approached by a Soviet agent suggesting that an agreement could be reached in which the Soviets would remove their missiles from Cuba if the United States promised not to invade the island. While White House staff scrambled to assess the validity of this “back channel” offer, Khrushchev sent Kennedy a message the evening of October 26, which meant it was sent in the middle of the night Moscow time. It was a long, emotional message that raised the specter of nuclear holocaust, and presented a proposed resolution that remarkably resembled what Scali reported earlier that day. “If there is no intention,” he said, “to doom the world to the catastrophe of thermonuclear war, then let us not only relax the forces pulling on the ends of the rope, let us take measures to untie that knot. We are ready for this.”

Although U.S. experts were convinced the message from Khrushchev was authentic, hope for a resolution was short-lived. The next day, October 27, Khrushchev sent another message indicating that any proposed deal must include the removal of U.S. Jupiter missiles from Turkey. That same day a U.S. U–2 reconnaissance jet was shot down over Cuba. Kennedy and his advisors prepared for an attack on Cuba within days as they searched for any remaining diplomatic resolution. It was determined that Kennedy would ignore the second Khrushchev message and respond to the first one. That night, Kennedy set forth in his message to the Soviet leader proposed steps for the removal of Soviet missiles from Cuba under supervision of the United Nations, and a guarantee that the United States would not attack Cuba.

It was a risky move to ignore the second Khrushchev message. Attorney General Robert Kennedy then met secretly with Soviet Ambassador to the United States, Anatoly Dobrynin, and indicated that the United States was planning to remove the Jupiter missiles from Turkey anyway, and that it would do so soon, but this could not be part of any public resolution of the missile crisis. The next morning, October 28, Khrushchev issued a public statement that Soviet missiles would be dismantled and removed from Cuba.

The crisis was over but the naval quarantine continued until the Soviets agreed to remove their IL–28 bombers from Cuba and, on November 20, 1962, the United States ended its quarantine. U.S. Jupiter missiles were removed from Turkey in April 1963.

The Cuban missile crisis stands as a singular event during the Cold War and strengthened Kennedy’s image domestically and internationally. It also may have helped mitigate negative world opinion regarding the failed Bay of Pigs invasion. Two other important results of the crisis came in unique forms. First, despite the flurry of direct and indirect communications between the White House and the Kremlin—perhaps because of it—Kennedy and Khrushchev, and their advisers, struggled throughout the crisis to clearly understand each others’ true intentions, while the world hung on the brink of possible nuclear war. In an effort to prevent this from happening again, a direct telephone link between the White House and the Kremlin was established; it became known as the “Hotline.” Second, having approached the brink of nuclear conflict, both superpowers began to reconsider the nuclear arms race and took the first steps in agreeing to a nuclear Test Ban Treaty.

During World War II, the United States and the Soviet Union fought together as allies against the Axis powers. However, the relationship between the two nations was a tense one. Americans had long been wary of Soviet communism and concerned about Russian leader Joseph Stalin’s tyrannical rule of his own country. For their part, the Soviets resented the Americans’ decades-long refusal to treat the USSR as a legitimate part of the international community as well as their delayed entry into World War II, which resulted in the deaths of tens of millions of Russians. After the war ended, these grievances ripened into an overwhelming sense of mutual distrust and enmity. 

Postwar Soviet expansionism in Eastern Europe fueled many Americans’ fears of a Russian plan to control the world. Meanwhile, the USSR came to resent what they perceived as American officials’ bellicose rhetoric, arms buildup and interventionist approach to international relations. In such a hostile atmosphere, no single party was entirely to blame for the Cold War; in fact, some historians believe it was inevitable.

The Cold War: Containment

By the time World War II ended, most American officials agreed that the best defense against the Soviet threat was a strategy called “containment.” In his famous “Long Telegram,” the diplomat George Kennan (1904-2005) explained the policy: The Soviet Union, he wrote, was “a political force committed fanatically to the belief that with the U.S. there can be no permanent modus vivendi [agreement between parties that disagree].” As a result, America’s only choice was the “long-term, patient but firm and vigilant containment of Russian expansive tendencies.” “It must be the policy of the United States,” he declared before Congress in 1947, “to support free peoples who are resisting attempted subjugation…by outside pressures.” This way of thinking would shape American foreign policy for the next four decades.

Did you know? The term 'cold war' first appeared in a 1945 essay by the English writer George Orwell called 'You and the Atomic Bomb.'

The Cold War: The Atomic Age

The containment strategy also provided the rationale for an unprecedented arms buildup in the United States. In 1950, a National Security Council Report known as NSC–68 had echoed Truman’s recommendation that the country use military force to contain communist expansionism anywhere it seemed to be occurring. To that end, the report called for a four-fold increase in defense spending.

In particular, American officials encouraged the development of atomic weapons like the ones that had ended World War II. Thus began a deadly “arms race.” In 1949, the Soviets tested an atom bomb of their own. In response, President Truman announced that the United States would build an even more destructive atomic weapon: the hydrogen bomb, or “superbomb.” Stalin followed suit.

As a result, the stakes of the Cold War were perilously high. The first H-bomb test, in the Eniwetok atoll in the Marshall Islands, showed just how fearsome the nuclear age could be. It created a 25-square-mile fireball that vaporized an island, blew a huge hole in the ocean floor and had the power to destroy half of Manhattan. Subsequent American and Soviet tests spewed radioactive waste into the atmosphere.

The ever-present threat of nuclear annihilation had a great impact on American domestic life as well. People built bomb shelters in their backyards. They practiced attack drills in schools and other public places. The 1950s and 1960s saw an epidemic of popular films that horrified moviegoers with depictions of nuclear devastation and mutant creatures. In these and other ways, the Cold War was a constant presence in Americans’ everyday lives.

The Cold War and the Space Race

Space exploration served as another dramatic arena for Cold War competition. On October 4, 1957, a Soviet R-7 intercontinental ballistic missile launched Sputnik (Russian for “traveling companion”), the world’s first artificial satellite and the first man-made object to be placed into the Earth’s orbit. Sputnik’s launch came as a surprise, and not a pleasant one, to most Americans. In the United States, space was seen as the next frontier, a logical extension of the grand American tradition of exploration, and it was crucial not to lose too much ground to the Soviets. In addition, this demonstration of the overwhelming power of the R-7 missile–seemingly capable of delivering a nuclear warhead into U.S. air space–made gathering intelligence about Soviet military activities particularly urgent.

In 1958, the U.S. launched its own satellite, Explorer I, designed by the U.S. Army under the direction of rocket scientist Wernher von Braun, and what came to be known as the Space Race was underway. That same year, President Dwight Eisenhower signed a public order creating the National Aeronautics and Space Administration (NASA), a federal agency dedicated to space exploration, as well as several programs seeking to exploit the military potential of space. Still, the Soviets were one step ahead, launching the first man into space in April 1961.

That May, after Alan Shepard become the first American man in space, President John F. Kennedy (1917-1963) made the bold public claim that the U.S. would land a man on the moon by the end of the decade. His prediction came true on July 20, 1969, when Neil Armstrong of NASA’s Apollo 11 mission, became the first man to set foot on the moon, effectively winning the Space Race for the Americans. 

U.S. astronauts came to be seen as the ultimate American heroes. Soviets, in turn, were pictured as the ultimate villains, with their massive, relentless efforts to surpass America and prove the power of the communist system.

The Cold War and the Red Scare

Meanwhile, beginning in 1947, the House Un-American Activities Committee (HUAC) brought the Cold War home in another way. The committee began a series of hearings designed to show that communist subversion in the United States was alive and well.

In Hollywood, HUAC forced hundreds of people who worked in the movie industry to renounce left-wing political beliefs and testify against one another. More than 500 people lost their jobs. Many of these “blacklisted” writers, directors, actors and others were unable to work again for more than a decade. HUAC also accused State Department workers of engaging in subversive activities. Soon, other anticommunist politicians, most notably Senator Joseph McCarthy (1908-1957), expanded this probe to include anyone who worked in the federal government. 

Thousands of federal employees were investigated, fired and even prosecuted. As this anticommunist hysteria spread throughout the 1950s, liberal college professors lost their jobs, people were asked to testify against colleagues and “loyalty oaths” became commonplace.

The Cold War Abroad

The fight against subversion at home mirrored a growing concern with the Soviet threat abroad. In June 1950, the first military action of the Cold War began when the Soviet-backed North Korean People’s Army invaded its pro-Western neighbor to the south. Many American officials feared this was the first step in a communist campaign to take over the world and deemed that nonintervention was not an option. Truman sent the American military into Korea, but the Korean War dragged to a stalemate and ended in 1953.

In 1955, The United States and other members of the North Atlantic Treaty Organization (NATO) made West Germany a member of NATO and permitted it to remilitarize. The Soviets responded with the Warsaw Pact, a mutual defense organization between the Soviet Union, Albania, Poland, Romania, Hungary, East Germany, Czechoslovakia and Bulgaria that set up a unified military command under Marshal Ivan S. Konev of the Soviet Union.

Other international disputes followed. In the early 1960s, President Kennedy faced a number of troubling situations in his own hemisphere. The Bay of Pigs invasion in 1961 and the Cuban missile crisis the following year seemed to prove that the real communist threat now lay in the unstable, postcolonial “Third World.” 

Nowhere was this more apparent than in Vietnam, where the collapse of the French colonial regime had led to a struggle between the American-backed nationalist Ngo Dinh Diem in the south and the communist nationalist Ho Chi Minh in the north. Since the 1950s, the United States had been committed to the survival of an anticommunist government in the region, and by the early 1960s it seemed clear to American leaders that if they were to successfully “contain” communist expansionism there, they would have to intervene more actively on Diem’s behalf. However, what was intended to be a brief military action spiraled into a 10-year conflict.

The End of the Cold War and Effects

Almost as soon as he took office, President Richard Nixon (1913-1994) began to implement a new approach to international relations. Instead of viewing the world as a hostile, “bi-polar” place, he suggested, why not use diplomacy instead of military action to create more poles? To that end, he encouraged the United Nations to recognize the communist Chinese government and, after a trip there in 1972, began to establish diplomatic relations with Beijing. At the same time, he adopted a policy of “détente”–”relaxation”–toward the Soviet Union. In 1972, he and Soviet premier Leonid Brezhnev (1906-1982) signed the Strategic Arms Limitation Treaty (SALT I), which prohibited the manufacture of nuclear missiles by both sides and took a step toward reducing the decades-old threat of nuclear war.

Despite Nixon’s efforts, the Cold War heated up again under President Ronald Reagan (1911-2004). Like many leaders of his generation, Reagan believed that the spread of communism anywhere threatened freedom everywhere. As a result, he worked to provide financial and military aid to anticommunist governments and insurgencies around the world. This policy, particularly as it was applied in the developing world in places like Grenada and El Salvador, was known as the Reagan Doctrine.

Even as Reagan fought communism in Central America, however, the Soviet Union was disintegrating. In response to severe economic problems and growing political ferment in the USSR, Premier Mikhail Gorbachev (1931-) took office in 1985 and introduced two policies that redefined Russia’s relationship to the rest of the world: “glasnost,” or political openness, and “perestroika,” or economic reform. 

Soviet influence in Eastern Europe waned. In 1989, every other communist state in the region replaced its government with a noncommunist one. In November of that year, the Berlin Wall–the most visible symbol of the decades-long Cold War–was finally destroyed, just over two years after Reagan had challenged the Soviet premier in a speech at Brandenburg Gate in Berlin: “Mr. Gorbachev, tear down this wall.” By 1991, the Soviet Union itself had fallen apart. The Cold War was over.
