This chapter describes how the United States’ global dominance from 1969 to 1980 met serious constraints. It links early technological triumphs, such as astronauts landing on the moon, to destabilizing events including Watergate revelations, economic stagnation, and the communist takeover of South Vietnam. It then explains Nixon’s foreign-policy priorities, focusing on reducing U.S. involvement in Vietnam through “Vietnamization,” while detailing escalation in Cambodia, antiwar backlash, and the roles of the Pentagon Papers and the My Lai massacre.

# 29 LIMITS OFA SUPERPOWER,1969-1980 If,when the chips are down,the world's most powerful nation,the United States,acts like a pitiful,helpless giant,the forces oftotalitarianism and anarchy will threaten free nations andfree institutions throughout the world. Richard Nixon,Address to the Nation,April 30,1970 In 1969,television viewers around the world witnessed the astonishing sight oftwo American astronauts walking on the moon's surface.This event,followedby a series of other successes for the U.S.space program,represented some ofthe high points of the 1970s.Offsetting these technological triumphs,however,were shocking revelations about White House participation in the Watergatecrime,a stagnant economy,and the fall of South Vietnam to communism.Increased foreign economic competition,oil shortages,rising unemployment,and high inflation made Americans aware that even the world's leading super-power would have to adjust to a fast-changing,less manageable world. # Richard Nixon's Foreign Policy In his January 1969 inaugural address,President Nixon promised to bringAmericans together after the turmoil of the 1960s.However,suspicious andsecretive by nature,Nixon soon began to isolate himself in the White Houseand create what Arthur Schlesinger Jr.called an “imperial presidency.”Nixon'sfirst interest was international relations,not domestic policy.Together with hisnational security adviser,Henry Kissinger(who became secretary of state dur-ing Nixon's second term),Nixon fashioned a pragmatic foreign policy thatreduced the tensions of the Cold War. ## Vietnam When Nixon took office,more than half a million U.S.troops were in Vietnam.His principal objective was to find a way to reduce U.S.involvement in the warwhile at the same time avoiding the appearance of conceding defeat.In a word,Nixon said the United States was seeking nothing less than"peace with honor." “Vietnamization.”Almost immediately,the new president began the pro-cess called “Vietnamization.”He announced that he would gradually withdrawU.S.troops from Vietnam and give the South Vietnamese the money,the weap-ons,and the training that they needed to take over the full conduct of the war.Under this policy,U.S.troops in South Vietnam went from over 540,000 in1969 to under 30,000 in 1972.Extending the idea of disengagement to otherparts of Asia,the president proclaimed the Nixon Doctrine,declaring that in thefuture Asian allies would receive U.S.support but without the extensive use ofU.S.ground forces. Opposition to Nixon's War Policies Nixon's gradual withdrawal of forcesfrom Vietnam reduced the number of antiwar protests.However,in April 1970,the president expanded the war by using U.S.forces to invade Cambodia in aneffort to destroy Vietnamese Communist bases in that country.A nationwideprotest on college campuses against this action resulted in the killing of fouryouths by National Guard troops at Kent State in Ohio and two students at Jack-son State in Mississippi.In reaction to the escalation of the war,the U.S.Senate(but not the House)voted to repeal the Gulf of Tonkin Resolution. Also in 1970,the American public was shocked to learn about a 1968 mas-sacre of women and children by U.S.troops in the Vietnamese village of MyLai.Further fueling the antiwar sentiment was the publication by the New YorkTimes of the Pentagon Papers,a secret government history documenting themistakes and deceptions of government policy-makers in dealing with Vietnam.The papers had been turned over,or "leaked,"to the press by Daniel Ellsberg,aformer Defense Department analyst U.S.FORCES INVIETNAM,1964 to 1973 Total Number of Troops(use scale on the left) Source:U.S.National Archives and Records Administration.Vietnam Conflict ExtractData File and other sources.
