Through United Nations, Cold War and NATO

  • Final stages of World War II included the challenge of defeating Japan with minimal American casualties. Truman asked Moscow to invade from the north, and decided to drop two atomic bombs.
  • Post-war Reconstruction: Following the end of World War II, Truman faced the task of rebuilding Europe and Japan. He implemented the Marshall Plan to provide economic aid to Europe and Washington supervised the reconstruction of Japan.
  • Formation of the United Nations: Truman played a key role in the formation of the United Nations, which was established in 1945 to promote international cooperation and prevent another world war. Because of the Soviet veto, it was ineffective in most major disputes.
  • Cold War: Truman led the nation into the Cold War in 1947, a period of heightened tensions and rivalry between the United States and the Soviet Union. Truman helped form the NATO military alliance. He implemented the policy of containment, which aimed to stop the spread of communism and limit Soviet influence around the world.
  • Korean War: In 1950, North Korea invaded South Korea, leading to a bloody conflict that lasted until 1953. Truman authorized U.S. military intervention in the conflict, which led to a protracted and costly war. He rejected the advice of General Douglas MacArthur, and fired him in 1951.
  • Nuclear arms race: Truman made the decision to build the hydrogen bomb. He oversaw the development of the U.S. nuclear arsenal and the start of the nuclear arms race with the Soviet Union, which had far-reaching implications for U.S. foreign policy.

Taking office in April 1945 in the last stages of winning World War II, Truman worked with the main American Allies, especially Britain, the Soviet Union and China. He distrusted the Soviets. The challenges were to achieve victory over Germany and Japan; deal with the chaos in Europe and Asia in the aftermath of World War II; handle the beginning of the Cold War with the USSR; and launch new international organizations such as the United Nations and the World Bank. Truman's presidency was a turning point in foreign affairs, as the United States engaged in a liberal internationalist foreign policy and renounced isolationism by engaging in a long global conflict with the Soviet Union and its allies, forming NATO, and fighting China in the Korean War to a deadlock.

Truman took office upon the death of Franklin D. Roosevelt during the final months of war. Until then Truman had little interest in foreign affairs and no knowledge of Roosevelt's plans. He relied heavily on advisers like George Marshall and Dean Acheson, both of whom served as Secretary of State. Germany surrendered days after Truman took office, but Japan initially refused to surrender or negotiate. In order to force Japan's surrender without resorting to an invasion of the main Japanese islands, Truman approved of plans to drop atomic bombs on two Japanese cities. Even before Germany and Japan surrendered, the Truman administration worked with Moscow, London and other Allies to establish post-war international institutions and agreements. Most hope was placed in the United Nations until Moscow's veto made it ineffective. In economics there was the International Refugee Organization, and the General Agreement on Tariffs and Trade. The Truman administration embarked on a policy of rebuilding democracy and the economy in Japan and West Germany. It acted practically alone in Japan, and with Moscow, London and Paris in Germany.

Tensions between the United States and the Soviet Union escalated after 1945, and by 1947 the two countries had entered a sustained period of geopolitical tension known as the Cold War. Truman adopted a policy of containment, in which the U.S. would attempt to prevent the spread of Communism but would not actively seek to regain territory already lost to Communism. He also announced the Truman Doctrine, a policy of aiding countries in danger of falling to Communism. Pursuant to this doctrine, Truman convinced Congress to provide an unprecedented aid package to Greece and Turkey, overcoming opposition from isolationists and some on the left who favored more conciliatory policies towards the Soviet Union. The following year, Truman convinced Congress to approve the Marshall Plan, $13 billion aid package enacted to rebuild Western Europe. In 1949, the U.S., Canada, and several European countries signed the North Atlantic Treaty, establishing the NATO military alliance. Meanwhile, domestic fears of Soviet espionage led to a Red Scare and the rise of McCarthyism in the United States.

The Truman administration attempted to mediate the Chinese Civil War and failed. The Communist forces under Mao Zedong took control of Mainland China in 1949. In June 1950 Communist North Korea invaded South Korea in an attempt to reunify the country. Acting under the aegis of the United Nations, the U.S. intervened, defeated the invaders, and prepared to unify Korea UN terms. However, in late 1950 millions of Chinese soldiers entered Korea and pushed the allies back. The war settled into a stalemate along a line close to its starting point. Truman left office quite unpopular, but scholars generally consider him to be an above average president, and his administration has been credited for establishing Cold War policies that contained the Soviets.

Leadership

At first Truman kept all of Roosevelt's cabinet, but by late 1946 only one remained. Even as vice president, knowing of the president's poor health, he showed little curiosity about Roosevelt's postwar plans and was kept out of the loop. Furthermore, he had a small White House staff that knew little about diplomacy. As president he relied heavily on top officials from the State Department. Truman quickly replaced Secretary of State Edward Stettinius Jr. with James F. Byrnes, a personal friend from Senate days. By 1946, Truman was taking a hard line against the Kremlin, although Byrnes was still trying to be conciliatory. The divergence in policy was intolerable. Truman replaced Byrnes with the highly prestigious five-star army general George Marshall in January 1947, despite Marshall's failure in negotiating a settlement in the Chinese Civil War. In 1947, James Forrestal became the first Secretary of Defense, with his department overseeing all three branches of the United States Armed Forces. Mental illness sent Forrestal into retirement in 1949, and he was replaced successively by Louis A. Johnson who did poorly. Then came Marshall, and finally Robert A. Lovett.

At the Department of State, the key person was Dean Acheson, who replaced Marshall as secretary in 1949. The Marshall Plan embodied Acheson's analysis of the European crisis; he designed America's role. As tensions mounted with Moscow, Acheson moved from guarded optimism to pessimism. He decided negotiations were futile, and the United States had to mobilize a network of allies to resist the Kremlin's quest for world domination, using both military and especially economic power. Downplaying the importance of communism in China, Acheson emphasized Europe, and took the lead, as soon as he became Secretary of State in January 1949, to nail down the NATO alliance. It worked closely with the major European powers, as well as cooperating closely with Republican Senator Arthur Vandenberg, building bipartisan support at a time when the Republican Party controlled Congress after the 1946 midterms. According to Townsend Hoopes, throughout his long career, Acheson displayed:

exceptional intellectual power and purpose, and tough inner fiber. He projected the long lines and aristocratic bearing of the thoroughbred horse, a self-assured grace, an acerbic elegance of mind, and a charm whose chief attraction was perhaps its penetrating candor. ... [He] was swift-flowing and direct. ... Acheson was perceived as an 18th-century rationalist ready to apply an irreverent wit to matters public and private.

The American occupation of Japan was nominally an Allied endeavor, but in practice it was run by General Douglas MacArthur, with little or no consultation with the Allies or with Washington. His responsibilities were enlarged to include the Korean War, till he broke with Truman on policy issues and was fired in highly dramatic fashion in 1951. Policy for the occupation of West Germany was much less controversial, and the decisions were made in Washington, with Truman himself making the key decision to rebuild West Germany as an economic power.

Roosevelt had handled all foreign policy decisions on his own, with a few advisors such as Harry Hopkins, He helped Truman too, even though he was dying of cancer. Roosevelt's final Secretary of State, Edward R. Stettinius was an amiable businessman who succeeded at reorganization of the department, and spent most of his attention in the creation of the United Nations. When that was accomplished, Truman replaced him with James F. Byrnes, whom Truman knew well from their Senate days together. Byrnes was more interested in domestic than foreign affairs. He was secretive, not telling Truman about major developments. Dean Acheson by this point was the number two person in State, and worked well with Truman. The president finally replaced Byrnes with Marshall. With the world in incredibly complex turmoil, international travel was essential. Byrnes spent 62% of his time abroad; Marshall spent 47% and Acheson 25%.
