On March 12, 1947, President Harry Truman addressed Congress on the “gravity of the situation which confronts the world today.” In his request for economic assistance to Greece and Turkey, Truman made his famous pledge 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.” He warned Congress that Americans needed to take action because the “free people of the world look to us for support in maintaining their freedoms.”
The “Truman Doctrine” outlined the moral and economic stake the United States had in fighting communism abroad. President Truman used the opportunity to link global economic and national security interests in ways that would dramatically expand the president’s institutional power and international role as a leader of the “free world.”
The Truman Doctrine
Beginning in World War II, a massive “warfare state” emerged, transforming the place of the federal government, and the executive branch in particular, in the lives of individuals at home and across the world. 1 The Cold War saw a bipartisan acceptance of multilateralism in foreign affairs as the country joined the United Nations and the North Atlantic Treaty Organization and pledged to “support free peoples who are resisting attempted subjugation.” During and after WWII, the United States grew into an international “arsenal of democracy.” 2 This required tremendous institutional expansion of the executive branch, economic arrangements—including income taxes on individuals and high levels of corporate taxes—and ideological commitments to internationalism and the policy of containment, as famously outlined in the 1950 National Security Council Report 68 (NSC 68). 3
Historians have examined how ideology, economic visions, and personalities have shaped international diplomacy and military endeavors during the Cold War. 4 The presidency looms large in these historical accounts. As diplomatic historian Stephen Rabe points out in an overview of Cold War presidents, a recent bibliography of Eisenhower’s foreign policy contained 840 scholarly sources. 5 The presidency dominates the history of post-WWII foreign relations because presidents set the rhetorical parameters of international relations, just as Truman did in 1947, and had the institutional authority to take action. During this time, Congress deliberately strengthened the authority of the presidency with the Atomic Energy Act of 1946 and the National Security Act of 1947, which created the National Security Agency, National Security Council and the Central Intelligence Agency.
As historian James Sparrow argues, this legislation gave the president concentrated power to “safeguard the ‘free world’” abroad by monitoring international conflicts and at home by “constantly surveilling the loyalty of citizens to preempt internal subversion of a ‘free society.’” 6 Cold War presidents had the resources and the power to plunge the country into military commitments, unknown to members of Congress and the broader public, in the interest of national security. 7 As a result, as Lewis Gould notes, the presidency stood as “the only institution in government that could pursue a course of action on a sustained and coherent basis.” 8 In this section, students will examine how the shifting international context influenced the responsibilities and operation of the presidency both at home and abroad.
Defending Freedom Abroad:
The Cold War made national security issues a daily concern of the president, who now had the responsibility not only to protect the atomic bomb from misuse but also to understand the political struggles in smaller countries across the globe. As historians have noted, the ideological lens of the Cold War shaped how presidents understood revolutionary nationalism across the globe. Especially in the global South, the “prism of the Soviet–American confrontation” influenced their perception of international conflicts. 9 Truman’s successors, Dwight Eisenhower, John Kennedy, Lyndon Johnson, and Richard Nixon, inherited ongoing military operations and international commitments from their predecessors. While some were public, others were covert. All of them, however, presented presidents an unprecedented opportunity to wage war from the Oval Office.
On April 25, 1945, Secretary of War Henry Stimson and the Manhattan Project chief General Leslie Groves secretly met with Harry Truman. They explained to the new president that in four months, “we shall in all probability have completed the most terrible weapon ever known in human history, one bomb of which could destroy a whole city.” The two men told Truman how the weapon would become the “primary question of our foreign relations,” emphasizing the moral gravity of deciding to deploy it. “Our leadership in the war and in the development of this weapon has placed a certain moral responsibility upon us which we cannot shirk without very serious responsibility for any disaster to civilization which it would further.” Truman listened intently to the report, knowing that he would have to make a decision as commander in chief about whether to use the atomic bomb.
President Truman’s subsequent decision to drop the atomic bomb on Hiroshima on August 6 and Nagasaki three days later has caused heated controversy.
Using the collection of documents from the National Security Archive’s collection of primary sources on “The Atomic Bomb and the End of World War II,” have students meet in small groups to examine the following historical questions that have generated political, military, and moral debates since 1945.
Legacy of the Manhattan Project: The Expansion of the Military–Industrial–University Complex
Following the Manhattan Project, the pursuit of technological and military superiority encouraged government support of scientific research in universities across the country. Though research funding from the federal government only totaled $97 million in 1940, it escalated to $1.6 billion during World War II and then $2.1 billion in 1953. President Eisenhower further increased federal funding in scientific research following the Soviet launch of Sputnik I, the world’s first artificial satellite to orbit the Earth in 1957.
Outlining how the Eisenhower administration responded to the Sputnik launch, these documents provide insight into the relationships between corporations, universities, professionals, individual students, and Eisenhower’s National Security Council. The ramifications of the atomic age unleashed by the successful Manhattan Project also shaped public and private behaviors in school and the home, as the two videos produced by the federal government’s Office of Civilian Defense illustrate.
