The Imbalance of Power, 1953-1965
The U.S. path to a major land war in South Vietnam was closely related to a new global distribution of power. The United States's emergence, during the Korean War, as strategically dominant vis-a-vis the Soviet Union changed the relationship between the two superpowers so profoundly that no Cold War issue remained untouched. Once it became clear that the Soviet Union could not provide a counterweight to U.S. military power, the United States had a new freedom of action, which translated into more aggressive and interventionist policies.
For decades, no distinction was made between different periods in the diplomatic history of the Cold War, because no one had noted any marked change in the fundamental relationship between the two major antagonists. Since the late 1980s, however, a few scholars have established that a key turning point in U.S. Cold War policy occurred during the Korean War and that this was directly attributable to the achievement by the United States of clear-cut dominance over the Soviet Union in strategic weapons.
Prior to that U.S. military breakthrough, the East-West balance of power was ambiguous and unstable. Both sides viewed the power balance primarily in a European context, as major powers had done before World War II. Despite the U.S. atomic monopoly from 1945 to 1949, moreover, the role of nuclear weapons in the power balance was not yet clear to either Moscow or Washington. Notwithstanding the destructive power of the atomic weapons of that period, the U.S. military did not view them as capable of destroying either U.S. or Soviet society. As late as 1949, the idea that the United States could use atomic weapons either to fight a war with the USSR or to influence Soviet behavior was still seriously questioned by many U.S. officials. Furthermore, U.S. intelligence vastly exaggerated Moscow's ability to wage war beyond its existing security sphere in Eastern Europe.
During the 1949-50 period, the Soviet Union exploded its first atomic bomb, the Chinese Communists established the People's Republic of China, and the USSR at first at least countenanced and then actively supported the North Korean invasion of South Korea. Meanwhile, the PRC gave military assistance to the Communist-led Viet Minh war of resistance to the French in Indochina. This period of Sino-Soviet initiative in the Cold War coincided with the high point of fear in Washington that the USSR might launch a "global war." Many U.S. military officials and some civilians felt that war with the Soviet Union was likely and that the United States should attack first. They also believed, however, that the United States could not take such a step until the balance of power was more favorable, particularly in regard to atomic weapons and strategic bombers.
The Truman administration had decided even before the Korean War on a massive military buildup that would decisively change both the reality and the perception of that distribution of power. Secretary of State Dean Acheson later recalled that the administration's response to the Soviet atomic bomb test in 1949 was to "make a colossal effort" at rearmament, creating "real power" in order to have a "psychological impact on the Soviets." According to NSC-68, the official blueprint for U.S. Cold War policy adopted by the Truman administration prior to the Korean War, the objective of the military buildup was to create a "situation to which the Kremlin would find it expedient to accommodate itself, first by relaxing tensions and pressures and then by gradual withdrawal."
The idea that a dramatic imbalance of military power would compel the USSR to withdraw from Eastern Europe vastly exaggerated its potential impact. Nevertheless, the massive rearmament carried out during the Korean War brought about a far-reaching transformation of U.S. Cold War policy and the dynamics of U.S.-Soviet relations. No one particular moment after the start of the Korean War can be identified as the point at which this transformation was complete. Rather, the period of the Korean War marked a transition from one distribution of power to another. By late 1952, the leading U.S. military and civilian policymakers of the Truman administration were already confident that the United States held a commanding superiority over the USSR in strategic forces. That conclusion led, in turn, to a new willingness in the part of the administration to make a military commitment to Iran and to pursue a much more aggressively interventionist policy within Iran, including a possible coup against the nationalist regime of Premier Mohammed Mossadegh, despite the risk of Soviet intervention and military confrontation with the USSR. The new policy was based on the confidence that the USSR would be deterred by fear of war with the United States.
The new imbalance of power altered the incoming Eisenhower admin-istration's definition of its diplomatic objectives as well. Secretary of State John Foster Dulles believed in early 1953 that the United States was now in a far stronger position to get the Korean armistice terms it wanted "in view of our much greater power and the Soviet Union's weakness currently." The Joint Chiefs of Staff similarly believed in late 1953 that the United States was now strong enough in relation to the USSR to fully assert its rights in Berlin, whereas they believed it had not been strong enough to do so in 1948-49. "They must be scared as hell," Eisenhower said of the Soviet leadership shortly before the end of the Korean War.
U.S. AND SOVIET POWER CAPABILITIES
The U.S. achievement between 1950 and 1952 of a commanding military superiority over the USSR, particularly in strategic weapons, was made possible by the much larger, more technologically advanced, and more efficient economy of the United States. The differences between the U.S. and Soviet economies were therefore a crucial factor in the changing distribution of power during this period. In 1953, the U.S. gross national product was 2.6 times larger than that of the Soviet Union, and ten years later, it was still almost 2.2 times larger, according to a more recent estimate. Even more important, the Soviet economy suffered from a huge "productivity gap" in relation to the U.S. economy, getting only an estimated 20 percent of the U.S. output per unit of labor and capital input using Soviet domestic prices, and 45 percent when dollars are used. And the Soviet technological lag behind the United States was estimated to be twenty-five years on average across all sectors, which further increased the disparity between the economic bases of the two states. Thus an index of effective economic power, combining GNP with productivity and technological prowess, would show the U.S. economic power base in the 1950s and 1960s to have been several times greater than that of the Soviet Union.
In theory, the stark contrast in their respective power bases need not have ruled out a balance of power between the two superpowers. Nations have a certain capability to mobilize resources for national defense or the exercise of international power, based on the degree of popular understanding and support for national objectives, but also on the relative cost of the objectives to the population. An increased mobilization of resources may be achieved, as Thomas J. Christensen has shown in the case of U.S.
