Succession to the presidency of Harry S. Truman

Roosevelt died suddenly of a cerebral hemorrhage on April 12, 1945, leaving Truman and the public in shock. Truman told reporters the day after taking the oath of office that he felt as if “the moon, the stars, and all the planets had fallen” on him and asked them to pray for him. He was hardly, however, as scholars have noted, a political naïf. Although he had no foreign policy experience, he was a capable administrator of large bureaucracies and a skilled politician who knew how to use the press to his purposes.

Truman was sworn in as president on the same day as Roosevelt’s death, which was just weeks away from Truman’s 61st birthday. He began his presidency with great energy, making final arrangements for the San Francisco meeting to draft a charter for the United Nations, helping to arrange Germany’s unconditional surrender on May 8, and traveling to Potsdam in July for a meeting with Allied leaders to discuss the fate of postwar Germany. While in Potsdam Truman received word of the successful test of an atomic bomb at Los Alamos, New Mexico, and it was from Potsdam that Truman sent an ultimatum to Japan to surrender unconditionally or face “utter devastation.” When Japan did not surrender and his advisers estimated that up to 500,000 Americans might be killed in an invasion of Japan, Truman authorized the dropping of atomic bombs on the cities of Hiroshima (August 6) and Nagasaki (August 9), killing more than 100,000 men, women, and children. This remains perhaps the most controversial decision ever taken by a U.S. president, one that scholars continue to debate today. (See Sidebar: The Decision to Use the Atomic Bomb.) In his address to the American people on August 7, Truman said in part:

It was to spare the Japanese people from utter destruction that the ultimatum of July 26 was issued at Potsdam. Their leaders promptly rejected that ultimatum. If they do not now accept our terms they may expect a rain of ruin from the air, the like of which has never been seen on this earth….The fact that we can release atomic energy ushers in a new era in man’s understanding of nature’s forces.

Japan surrendered on August 14, and the Pacific war ended officially on September 2, 1945.

Scarcely had the guns of World War II been silenced than Truman faced the threat of Soviet expansionism in eastern Europe. Early in 1946 Truman brought British statesman Winston Churchill, who had just completed his first term (1940–45) as prime minister, to Missouri to sound the alarm with his “iron curtain” address. The following year Truman put the world on notice through his Truman Doctrine that the United States would oppose communist aggression everywhere; specifically, he called for economic aid to Greece and Turkey to help those countries resist communist takeover. In the process, Truman shifted U.S. foreign policy from cooperation with the Soviet Union to “containment” of Soviet power. On March 12, 1947, he addressed a joint session of Congress, saying in part:

One of the primary objectives of the foreign policy of the United States is the creation of conditions in which we and other nations will be able to work out a way of life free from coercion….We shall not realize our objectives, however, unless we are willing to help free peoples to maintain their free institutions and their national integrity against aggressive movements that seek to impose upon them totalitarian regimes. This is no more than a frank recognition that totalitarian regimes imposed on free peoples, by direct or indirect aggression, undermine the foundations of international peace and hence the security of the United States….I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures. I believe that we must assist free peoples to work out their own destinies in their own way. I believe that our help should be primarily through economic and financial aid, which is essential to economic stability and orderly political processes.

Later in 1947 the president backed Secretary of State George Marshall’s strategy for undercutting communism’s appeal in western Europe by sending enormous amounts of financial aid (ultimately about $13 billion) to rebuild devastated European economies. Both the Truman Doctrine and the Marshall Plan (officially the European Recovery Program) achieved their objectives, but they also contributed to the global polarization that characterized five decades of Cold War hostility between East and West.

Winning a second term

As the presidential election of 1948 approached, the odds against Truman’s winning the presidency seemed enormous. The Republicans had triumphed in the congressional elections of 1946, running against Truman as the symbol of the New Deal. That electoral triumph seemed to indicate that the American people were weary of reform and of the Democratic Party. Worsening Truman’s chances for reelection was the defection of liberal Democrats, breaking with the president over his hard-line opposition to the Soviet Union; many of these liberals supported the candidacy of Henry A. Wallace, who was running as the Progressive Party candidate for president. At the Democratic National Convention, Southern delegates bolted as well, angry at the president for his strong civil rights initiatives; these Southern Democrats supported Strom Thurmond, the States’ Rights (“Dixiecrat”) presidential candidate.

But Truman surprised everyone. He launched a cross-country whistle-stop campaign, blasting the “do-nothing, good-for-nothing Republican Congress.” As he hammered away at Republican support for the antilabor Taft-Hartley Act (passed over Truman’s veto) and other conservative policies, crowds responded with “Give ’em hell, Harry!” The excitement generated by Truman’s vigorous campaigning contrasted sharply with the lacklustre speeches of Republican candidate Thomas E. Dewey, and Truman won by a comfortable margin, 49 percent to 45 percent; Wallace and Thurmond had little impact on the outcome.

Energized by his surprising victory, Truman presented his program for domestic reform in 1949. The Fair Deal included proposals for expanded public housing, increased aid to education, a higher minimum wage, federal protection for civil rights, and national health insurance. Despite Democratic majorities in the House and Senate, most Fair Deal proposals either failed to gain legislative majorities or passed in much weakened form. Truman succeeded, however, in laying the groundwork for the domestic agenda for decades to come.

In part, the Fair Deal fell victim to rising Cold War tensions that absorbed attention and resources. In 1949 Chinese communists finally won their long civil war, seizing control of the mainland. Almost simultaneously, the Soviet Union successfully tested a nuclear bomb, ending the nuclear monopoly enjoyed by the United States since 1945. Truman, who had faced down the Soviet threat to Berlin in 1948 with a massive airlift of food and supplies to sustain the noncommunist sectors of the city, led the United States into a collective security agreement with noncommunist European nations—the North Atlantic Treaty Organization (NATO)—to resist Soviet expansionism. In 1950 he authorized development of the hydrogen bomb in order to maintain an arms lead over the Soviets. By the end of the decade, the wartime alliance linking the United States and Soviet Union had been completely severed, and the two nations had embarked on an arms race of potentially world-destroying dimensions.
