FROM ISOLATIONISM TO ENGAGEMENT

The United States had a long history of avoiding foreign alliances that might require the commitment of its troops abroad. However, in accepting the realities of the post-World War II world, in which traditional powers like Great Britain or France were no longer strong enough to police the globe, the United States realized that it would have to make a permanent change in its foreign policy, shifting from relative isolation to active engagement.

On assuming the office of president upon the death of Franklin Roosevelt, Harry Truman was already troubled by Soviet actions in Europe. He disliked the concessions made by Roosevelt at Yalta, which had allowed the Soviet Union to install a Communist government in Poland. At the Potsdam conference, held from July 17 to August 2, 1945, Truman also opposed Stalin’s plans to demand large reparations from Germany. He feared the burden that this would impose on Germany might lead to another cycle of German rearmament and aggression—a fear based on that nation’s development after World War I.

Although the United States and the Soviet Union did finally reach an agreement at Potsdam, this was the final occasion on which they cooperated for quite some time. Each remained convinced that its own economic and political systems were superior to the other’s, and the two superpowers quickly found themselves drawn into conflict. The decades-long struggle between them for technological and ideological supremacy became known as the Cold War. So called because it did not include direct military confrontation between Soviet and U.S. troops, the Cold War was fought with a variety of other weapons: espionage and surveillance, political assassinations, propaganda, and the formation of alliances with other nations. It also became an arms race, as both countries competed to build the greatest stockpile of nuclear weapons, and proxy wars were fought on their behalf, primarily by the citizens of poorer nations, such as Korea and Vietnam.

CONTAINMENT ABROAD

In February 1946, George Kennan, a State Department official stationed at the U.S. embassy in Moscow, sent an eight-thousand-word message to Washington, DC. In what became known as the “Long Telegram,” Kennan maintained that Soviet leaders believed that the only way to protect the Soviet Union was to destroy “rival” nations and their influence over weaker nations. According to Kennan, the Soviet Union was not so much a revolutionary regime as a totalitarian bureaucracy that was unable to accept the prospect of a peaceful coexistence of the United States and itself. He advised that the best way to thwart Soviet plans for the world was to contain Soviet influence—primarily through economic policy—to those places where it already existed and prevent its political expansion into new areas. This strategy, which came to be known as the policy of containment, formed the basis for U.S. foreign policy and military decision making for more than thirty years.

As Communist governments came to power elsewhere in the world, American policymakers extended their strategy of containment to what became known as the domino theory under the Eisenhower administration: Neighbors to Communist nations, so was the assumption, were likely to succumb to the same allegedly dangerous and infectious ideology. Like dominos toppling one another, entire regions would eventually be controlled by the Soviets. The demand for anti-Communist containment appeared as early as March 1946 in a speech by Winston Churchill, in which he referred to an Iron Curtain that divided Europe into the “free” West and the Communist East controlled by the Soviet Union.

The commitment to containing Soviet expansion made necessary the ability to mount a strong military offense and defense. In pursuit of this goal, the U.S. military was reorganized under the National Security Act of 1947. This act streamlined the government in matters of security by creating the National Security Council and establishing the Central Intelligence Agency (CIA) to conduct surveillance and espionage in foreign nations. It also created the Department of the Air Force, which was combined with the Departments of the Army and Navy in 1949 to form one Department of Defense.

The Marshall Plan

By 1946, the American economy was growing significantly. At the same time, the economic situation in Europe was disastrous. The war had turned much of Western Europe into a battlefield, and the rebuilding of factories, public transportation systems, and power stations progressed exceedingly slowly. Starvation loomed as a real possibility for many. As a result of these conditions, Communism was making significant inroads in both Italy and France. These concerns led Truman, along with Secretary of State George C. Marshall, to propose to Congress the European Recovery Program, popularly known as the Marshall Plan. Between its implantation in April 1948 and its termination in 1951, this program gave $13 billion in economic aid to European nations.

Truman’s motivation was economic and political, as well as humanitarian. The plan stipulated that the European nations had to work together in order to receive aid, thus enforcing unity through enticement, while seeking to undercut the political popularity of French and Italian Communists and dissuading moderates from forming coalition governments with them. Likewise, much of the money had to be spent on American goods, boosting the postwar economy of the United States as well as the American cultural presence in Europe. Stalin regarded the program as a form of bribery. The Soviet Union refused to accept aid from the Marshall Plan, even though it could have done so, and forbade the Communist states of Eastern Europe to accept U.S. funds as well. Those states that did accept aid began to experience an economic recovery.

George C. Marshall and the Nobel Peace Prize

The youngest child of a Pennsylvania businessman and Democrat, George C. Marshall chose a military career. He attended the Virginia Military Institute, was a veteran of World War I, and spent the rest of his life either in the military or otherwise in the service of his country, including as President Truman’s Secretary of State. He was awarded the Nobel Peace Prize in 1953, the only soldier to ever receive that honor. Below is an excerpt of his remarks as he accepted the award.

There has been considerable comment over the awarding of the Nobel Peace Prize to a soldier. I am afraid this does not seem as remarkable to me as it quite evidently appears to others. I know a great deal of the horrors and tragedies of war. Today, as chairman of the American Battle Monuments Commission, it is my duty to supervise the construction and maintenance of military cemeteries in many countries overseas, particularly in Western Europe. The cost of war in human lives is constantly spread before me, written neatly in many ledgers whose columns are gravestones. I am deeply moved to find some means or method of avoiding another calamity of war. Almost daily I hear from the wives, or mothers, or families of the fallen. The tragedy of the aftermath is almost constantly before me.

I share with you an active concern for some practical method for avoiding war. . . . A very strong military posture is vitally necessary today. How long it must continue I am not prepared to estimate, but I am sure that it is too narrow a basis on which to build a dependable, long-enduring peace. The guarantee for a long continued peace will depend on other factors in addition to a moderated military strength, and no less important. Perhaps the most important single factor will be a spiritual regeneration to develop goodwill, faith, and understanding among nations. Economic factors will undoubtedly play an important part. Agreements to secure a balance of power, however disagreeable they may seem, must likewise be considered. And with all these there must be wisdom and the will to act on that wisdom.

What steps did Marshall recommend be taken to maintain a lasting peace? To what extent have today’s nations heeded his advice?

Showdown in Europe

The lack of consensus with the Soviets on the future of Germany led the United States, Great Britain, and France to support joining their respective occupation zones into a single, independent state. In December 1946, they took steps to do so, but the Soviet Union did not wish the western zones of the country to unify under a democratic, pro-capitalist government. The Soviet Union also feared the possibility of a unified West Berlin, located entirely within the Soviet sector. Three days after the western allies authorized the introduction of a new currency in Western Germany—the Deutsche Mark—Stalin ordered all land and water routes to the western zones of the city Berlin to be cut off in June 1948. Hoping to starve the western parts of the city into submission, the Berlin blockade was also a test of the emerging U.S. policy of containment.

Unwilling to abandon Berlin, the United States, Great Britain, and France began to deliver all needed supplies to West Berlin by air. In April 1949, the three countries joined Canada and eight Western European nations to form the North Atlantic Treaty Organization (NATO), an alliance pledging its members to mutual defense in the event of attack. On May 12, 1949, a year and approximately two million tons of supplies later, the Soviets admitted defeat and ended the blockade of Berlin. On May 23, the Federal Republic of Germany (FRG), consisting of the unified western zones and commonly referred to as West Germany, was formed. The Soviets responded by creating the German Democratic Republic, or East Germany, in October 1949.

CONTAINMENT AT HOME

In 1949, two incidents severely disrupted American confidence in the ability of the United States to contain the spread of Communism and limit Soviet power in the world. First, on August 29, 1949, the Soviet Union exploded its first atomic bomb—no longer did the United States have a monopoly on nuclear power. A few months later, on October 1, 1949, Chinese Communist Party leader Mao Zedong announced the triumph of the Chinese Communists over their Nationalist foes in a civil war that had been raging since 1927. The Nationalist forces, under their leader Chiang Kai-shek, departed for Taiwan in December 1949.

Immediately, there were suspicions that spies had passed bomb-making secrets to the Soviets and that Communist sympathizers in the U.S. State Department had hidden information that might have enabled the United States to ward off the Communist victory in China. Indeed, in February 1950, Wisconsin senator Joseph McCarthy, a Republican, charged in a speech that the State Department was filled with Communists. Also in 1950, the imprisonment in Great Britain of Klaus Fuchs, a German-born physicist who had worked on the Manhattan Project and was then convicted of passing nuclear secrets to the Soviets, increased American fears. Information given by Fuchs to the British implicated a number of American citizens as well. The most infamous trial of suspected American spies was that of Julius and Ethel Rosenberg, who were executed in June 1953 despite a lack of evidence against them. Several decades later, evidence was found that Julius, but not Ethel, had in fact given information to the Soviet Union.

Fears that Communists within the United States were jeopardizing the country’s security had existed even before the victory of Mao Zedong and the arrest and conviction of the atomic spies. Roosevelt’s New Deal and Truman’s Fair Deal were often criticized as “socialist,” which many mistakenly associated with Communism, and Democrats were often branded Communists by Republicans. In response, on March 21, 1947, Truman signed Executive Order 9835, which provided the Federal Bureau of Investigation with broad powers to investigate federal employees and identify potential security risks. State and municipal governments instituted their own loyalty boards to find and dismiss potentially disloyal workers.

In addition to loyalty review boards, the House Committee on Un-American Activities (HUAC), established in 1938 to investigate suspected Nazi sympathizers, after World War II also sought to root out suspected Communists in business, academia, and the media. HUAC was particularly interested in Hollywood because it feared that Communist sympathizers might use motion pictures as pro-Soviet propaganda. Witnesses were subpoenaed and required to testify before the committee; refusal could result in imprisonment. Those who invoked Fifth Amendment protections, or were otherwise suspected of Communist sympathies, often lost their jobs or found themselves on a blacklist, which prevented them from securing employment. Notable artists who were blacklisted in the 1940s and 1950s include composer Leonard Bernstein, novelist Dashiell Hammett, playwright and screenwriter Lillian Hellman, actor and singer Paul Robeson, and musician Artie Shaw.

TO THE TRENCHES AGAIN

Just as the U.S. government feared the possibility of Communist infiltration of the United States, so too was it alert for signs that Communist forces were on the move elsewhere. The Soviet Union had been granted control of the northern half of the Korean peninsula at the end of World War II, and the United States had control of the southern portion. The Soviets displayed little interest in extending its power into South Korea, and Stalin did not wish to risk confrontation with the United States over Korea. North Korea’s leaders, however, wished to reunify the peninsula under Communist rule. In April 1950, Stalin finally gave permission to North Korea’s leader Kim Il Sung to invade South Korea and provided the North Koreans with weapons and military advisors.

On June 25, 1950, troops of the North Korean People’s Democratic Army crossed the thirty-eighth parallel, the border between North and South Korea. The first major test of the U.S. policy of containment in Asia had begun, for the domino theory held that a victory by North Korea might lead to further Communist expansion in Asia, in the virtual backyard of the United States’ chief new ally in East Asia—Japan. The United Nations (UN), which had been established in 1945, was quick to react. On June 27, the UN Security Council denounced North Korea’s actions and called upon UN members to help South Korea defeat the invading forces. As a permanent member of the Security Council, the Soviet Union could have vetoed the action, but it had boycotted UN meetings following the awarding of China’s seat on the Security Council to Taiwan instead of to Mao Zedong’s People’s Republic of China.

On June 27, Truman ordered U.S. military forces into South Korea. They established a defensive line on the far southern part of the Korean peninsula near the town of Pusan. A U.S.-led invasion at Inchon on September 15 halted the North Korean advance and turned it into a retreat. As North Korean forces moved back across the thirty-eighth parallel, UN forces under the command of U.S. General Douglas MacArthur followed. MacArthur’s goal was not only to drive the North Korean army out of South Korea but to destroy Communist North Korea as well. At this stage, he had the support of President Truman; however, as UN forces approached the Yalu River, the border between China and North Korea, MacArthur’s and Truman’s objectives diverged. Chinese premier Zhou Enlai, who had provided supplies and military advisors for North Korea before the conflict began, sent troops into battle to support North Korea and caught U.S. troops by surprise. Following a costly retreat from North Korea’s Chosin Reservoir, a swift advance of Chinese and North Korean forces and another invasion of Seoul, MacArthur urged Truman to deploy nuclear weapons against China. Truman, however, did not wish to risk a broader war in Asia. MacArthur criticized Truman’s decision and voiced his disagreement in a letter to a Republican congressman, who subsequently allowed the letter to become public. In April 1951, Truman accused MacArthur of insubordination and relieved him of his command. The Joint Chiefs of Staff agreed, calling the escalation MacArthur had called for “the wrong war, at the wrong place, at the wrong time, and with the wrong enemy.” Nonetheless, the public gave MacArthur a hero’s welcome in New York with the largest ticker tape parade in the nation’s history.

By July 1951, the UN forces had recovered from the setbacks earlier in the year and pushed North Korean and Chinese forces back across the thirty-eighth parallel, and peace talks began. However, combat raged on for more than two additional years. The primary source of contention was the fate of prisoners of war. The Chinese and North Koreans insisted that their prisoners be returned to them, but many of these men did not wish to be repatriated. Finally, an armistice agreement was signed on July 27, 1953. A border between North and South Korea, one quite close to the original thirty-eighth parallel line, was agreed upon. A demilitarized zone between the two nations was established, and both sides agreed that prisoners of war would be allowed to choose whether to be returned to their homelands. Five million people died in the three-year conflict. Of these, around 36,500 were U.S. soldiers; a majority were Korean civilians.

As the war in Korea came to an end, so did one of the most frightening anti-Communist campaigns in the United States. After charging the U.S. State Department with harboring Communists, Senator Joseph McCarthy had continued to make similar accusations against other government agencies. Prominent Republicans like Senator Robert Taft and Congressman Richard Nixon regarded McCarthy as an asset who targeted Democratic politicians, and they supported his actions. In 1953, as chair of the Senate Committee on Government Operations, McCarthy investigated the Voice of America, which broadcast news and pro-U.S. propaganda to foreign countries, and the State Department’s overseas libraries. After an aborted effort to investigate Protestant clergy, McCarthy turned his attention to the U.S. Army. This proved to be the end of the senator’s political career. From April to June 1954, the Army-McCarthy Hearings were televised, and the American public, able to witness his use of intimidation and innuendo firsthand, rejected McCarthy’s approach to rooting out Communism in the United States. In December 1954, the U.S. Senate officially condemned his actions with a censure, ending his prospects for political leadership.

One particularly heinous aspect of the hunt for Communists in the United States, likened by playwright Arthur Miller to the witch hunts of old, was its effort to root out gay men and lesbians employed by the government. Many anti-Communists, including McCarthy, believed that gay men, referred to by Senator Everett Dirksen as “lavender lads,” were morally weak and thus were particularly likely to betray their country. Many also believed that lesbians and gay men were prone to being blackmailed by Soviet agents because of their sexual orientation, which at the time was regarded by psychiatrists as a form of mental illness.
