The wars in Korea and Vietnam were of a piece, directly related by virtue of U.S. global strategy and China's security concerns. This paper, focusing mainly on the U.S. side in these wars, argues that three characteristics of American policy had enduring meaning for the rest of the Cold War and even beyond: the official mindsets that led to U.S. involvement, the centrality of the China threat in American decision making, and the common legacy of intervention against nationalism and in support of authoritarian regimes. It is part of a continuing Asia-Pacific Journal series on the Korean War on the sixtieth anniversary of its outbreak.
1 Recall that U.S. entry into the war in Korea was soon accompanied by the rearmament of Germany, establishment of a common European defense strategy and command center, and an increase in U.S. ground forces in Europe.

As LaFeber writes, democratizing Japan was not the primary objective of the U.S. occupation. “The highest objectives were, first, to use Japan as the hub of an open, multilateral capitalism in Asia; second, to contain communism; and third to reassure neighbors by keeping Japan orderly and controlled.” The secret agreements, recently discovered by the new DPJ government in Tokyo, regarded use of U.S. bases and passage for nuclear-armed ships, including the right of U.S. ships carrying nuclear weapons to enter Japanese ports.

28 See, for instance, the cables of Ambassador (to Saigon) Henry Cabot Lodge in PP (B), pp. 208-10 and his comments at a meeting of the policy-making principals in July 1965, in Hunt, ed., Crises in U.S. Foreign Policy, pp. 352-53: “We have to do what we think we ought to do regardless of what the Saigon government does. As we move ahead on a new phase—it gives us the right and duty to do certain things with or without the government's approval.” That is clearly what happened in November 1963 when Kennedy in all but executive order authorized U.S. agreement to Diem's elimination.

42 Unlike in Korea, “the forgotten war,” the Vietnam War produced a huge literature on the political and cultural history of the country—but only after the United States had been involved for about a decade. That output shows no sign of slowing. Still, the Korean War has produced a number of distinguished works, including Bruce Cumings' two-volume history cited previously; William Stueck's The Korean War: An International History (Princeton, N.J.: Princeton University Press, 1995) and later works; Chen Jian's China's Road to the Korean War: The Making of the Sino-American Confrontation (New York: Columbia University Press, 1994); and David Halberstam's The Coldest Winter: America and the Korean War (New York: Hyperion, 2007).

45 See the testimony of Gordon Adams before the U.S. Senate Committee on the Budget, February 23, 2010 here. “The total resources requested [by the Obama defense department] are, in constant dollars, 16% higher than the 1952 Korean War budget peak, 26% higher than the peak defense budgets of 1985, and 36% higher than the 1968 peak year for Vietnam War-era defense budgets.”
46 When, for example, the British objected to American domination of decision making on the war and proposed that a committee might run it, Truman and General Omar Bradley responded that if anyone didn't like the way the war was being waged they could withdraw; the United States was in charge.

47 The War Powers Resolution was intended to restrict presidential prerogative with respect to the dispatch of troops abroad without Congressional authorization. But the resolution has never kept presidents from acting as they pleased, whether with reference to the WPR or not. Efforts in Congress to invoke the WPR have typically failed, usually due to deference in Congress to presidential power in foreign affairs. Such was the case recently when Representative Dennis Kucinich (D-OH) tried to use the war powers bill to force U.S. withdrawal from Afghanistan within 30 days or by the end of 2010 at the latest. See Carl Hulse, “House Rejects Plan to Leave Afghanistan By Year's End,” New York Times, March 11, 2010, p. A6.

51 Thus, according to Michael T. Klare (“‘Two, Three, Many Afghanistans,‘” The Nation, April 26, 2010, pp. 21-24), the Pentagon's latest Quadrennial Defense Review indicates that Obama, like Kennedy in the 1960s, “seeks to fashion a new military posture that shifts the emphasis from conventional combat to brush-fire wars and counterinsurgency.” This “new posture” does not alter the overall U.S. strategy, which remains (as Klare quotes the QDR) that “The strength and influence of the United States are deeply intertwined with the fate of the broader international system. The U.S. military must therefore be prepared to support broad national goals of promoting stability in key regions, providing assistance to nations in need, and promoting the common good.”
