Nixon and Vietnamization: 1969–1975 Cambodia With Vietnamization under way, Nixon and Kissinger still had a few tricks up their sleeves. While reducing U.S. personnel in Vietnam slightly in 1969, they also sought to defeat the North Vietnamese by destroying their supply lines and base camps in neighboring Cambodia. Although Cambodia was officially a neutral nation, the NVA had long used its territory to run weapons and troops, circumventing the U.S. soldiers, bombers, and raiding parties that were operating in Vietnamese territory. In the spring of 1970, Nixon authorized a series of bombing raids in Cambodia and sent both U.S. and ARVN troops across the border, all without the consent or even awareness of Congress. When the secret Cambodian campaign was revealed in a New York Times exposé in May 1970, it sent shock waves through the uninformed Congress and the American public. Renewed public outcry and waves of protests eventually convinced Nixon to rescind the order that summer. Nonetheless, he authorized a similar action in March 1971, secretly sending ARVN forces across the border into Laos. Watergate Despite Nixon’s landslide reelection victory, his days in office were numbered; on top of the uproar over the Cambodia bombings, the Watergate scandal had broken in late 1972. In short, Nixon had approved a secret burglary of the Democratic Party headquarters at the Watergate Hotel in Washington, D.C., prior to the election, but the burglars were caught. Evidence surfaced that Nixon had authorized illegal measures to discredit prominent Democratic opponents and other people on his personal“enemies list.” Ultimately, when it became clear that Nixon himself had broken the law by covering up the scandal, many in the United States began calling for his impeachment. Key People Richard M. Nixon - 37th U.S. president; despite policy of Vietnamization and troop withdrawals, expanded scope of war into Cambodia and Laos; forced peace settlement out of North Vietnam in 1973; resigned amid Watergate scandal in 1974 Henry A. Kissinger - Nixon’s national security advisor and later secretary of state; negotiated cease-fire with Le Duc Tho Le Duc Tho - North Vietnamese emissary who negotiated cease-fire with Kissinger at secret talks in Paris Impact of Nixon’s New Policies Vietnamization and the Nixon Doctrine did reduce combat casualties but also turned U.S. foreign policy upside down. In declaring that the United States would no longer commit troops to stop Communist revolutions abroad, Nixon effectively revoked Eisenhower’s, Kennedy’s, and Johnson’s policies of using the U.S. military to prevent Communism from spreading. Although his predecessors had sent troops to fight Soviet influence in the farthest corners of the world, Nixon believed that the political cost of more dead U.S. servicemen was simply too great. Vietnamization and the Nixon Doctrine When President Richard M. Nixon took office in January 1969, he chose former political science professor Henry A. Kissinger as his national security advisor. Kissinger saw Vietnam as a mistake and pushed for disengagement. Not long into his term, Nixon announced a new policy of Vietnamization to gradually withdraw the more than 500,000 American soldiers from Vietnam and return control of the war to the South Vietnamese ARVN.
