The Vietnam War
U.S. involvement in Vietnam dated to the Truman administration, when economic and military aid was provided to deter a communist takeover of French Indochina. When France withdrew and Vietnam was divided in two in 1954, the United States continued to support anticommunist forces in South Vietnam. By 1964, communist insurgents were winning their struggle against the government of South Vietnam, which a decade of American aid had failed to strengthen or reform. In August, following an allegedly unprovoked attack on U.S. warships patrolling the Gulf of Tonkin, a resolution pledging complete support for American action in Vietnam was passed unanimously in the House of Representatives and with only two dissenting votes in the Senate.

After the fall elections, Johnson began deploying a huge force in Vietnam (more than half a million troops in 1968, together with strong air and naval units). This power was directed not only against the Viet Cong insurgents but also against North Vietnam, which increased its efforts as American participation escalated. Despite massive U.S. bombing of North Vietnam, the communists refused to yield. On January 30, 1968, disregarding a truce called for the Tet (lunar new year) holiday, the communists launched an offensive against every major urban area in South Vietnam. Although the Tet Offensive was a military failure, it proved to be a political victory for the communists because it persuaded many Americans that the war could not be ended at a bearable price. Opposition to U.S. involvement became the major issue of the 1968 election. After Sen. Eugene McCarthy, a leading critic of the war, ran strongly against him in the New Hampshire primary, Johnson announced that he would not seek or accept renomination. He also curtailed bombing operations, opened peace talks with the North Vietnamese, and on November 1 ended the bombing of North Vietnam.
While war efforts were being reduced, violence within the United States seemed to be growing. Just two months after King’s assassination, Sen. Robert F. Kennedy, a leading contender for the Democratic presidential nomination, was assassinated. President Johnson then secured the nomination of Vice Pres. Hubert H. Humphrey at the Democratic National Convention at Chicago, where violence again erupted as antiwar demonstrators were manhandled by local police. Humphrey lost the election to the Republican nominee, former vice president Richard Nixon. The narrowness of Nixon’s margin resulted from a third-party campaign by the former governor of Alabama, George Wallace, who attracted conservative votes that would otherwise have gone to Nixon. Democrats retained large majorities in both houses of Congress.

The 1970s
The Richard M. Nixon administration
Foreign affairs
Nixon and his national security adviser, Henry Kissinger, believed that American power relative to that of other nations had declined to the point where a fundamental reorientation was necessary. They sought improved relations with the Soviet Union to make possible reductions in military strength while at the same time enhancing American security. In 1969 the Nixon Doctrine called for allied nations, especially in Asia, to take more responsibility for their own defense. Nixon’s policy of détente led to Strategic Arms Limitation Talks (SALT), which resulted in a treaty with the Soviet Union all but terminating antiballistic missile systems. In 1972 Nixon and Kissinger negotiated an Interim Agreement that limited the number of strategic offensive missiles each side could deploy in the future. Nixon also dramatically reversed Sino-American relations with a secret visit by Kissinger to Beijing in July 1971. This led to a presidential visit the following year and to the establishment of strong ties between the two nations. Nixon then visited Moscow as well, showing that détente with the rival communist powers did not mean that he would play them off against one another.

The limits of détente were tested by the Arab-Israeli Yom Kippur War of October 1973, in which the United States supported Israel and the Soviet Union the Arabs. Nixon managed the crisis well, preventing the confrontation with the Soviets from getting out of hand and negotiating a cease-fire that made possible later improvements in Israeli-Egyptian relations. Nixon and Kissinger dramatically altered U.S. foreign relations, modifying containment, reducing the importance of alliances, and making the balance of power and the dual relationship with the Soviet Union and China keystones of national policy.
Meanwhile, inconclusive fighting continued in Vietnam, and unproductive peace talks continued in Paris. Although in 1969 Nixon announced his policy of “Vietnamization,” according to which more and more of the fighting was to be assumed by South Vietnam itself, he began by expanding the fighting in Southeast Asia with a 1970 “incursion” into Cambodia. This incident aroused strong protest; student demonstrations at Kent State University in Ohio led on May 4 to a confrontation with troops of the Ohio National Guard, who fired on the students without orders, killing four and wounding several others. National revulsion at this act led to serious disorders at many universities and forced some of them to close for the remainder of the term. Further antiwar demonstrations followed the 1971 U.S. invasion of Laos and Nixon’s decision to resume intensive bombing of North Vietnam in 1972.

Peace negotiations with North Vietnam slowly progressed, and a cease-fire agreement was finally signed on January 27, 1973. The agreement, which provided for exchange of prisoners of war and for U.S. withdrawal from South Vietnam without any similar commitment from the North Vietnamese, ended 12 years of U.S. military effort that had taken some 58,000 American lives.

Domestic affairs
When Chief Justice Earl Warren, who had presided over the most liberal Supreme Court in history, retired in 1969, Nixon replaced him with the conservative Warren Burger. Three other retirements enabled Nixon to appoint a total of four moderate or conservative justices. The Burger court, though it was expected to, did not reverse the policies laid down by its predecessor.
Congress enacted Nixon’s revenue-sharing program, which provided direct grants to state and local governments. Congress also expanded social security and federally subsidized housing. In 1972 the Congress, with the support of the president, adopted a proposed constitutional amendment guaranteeing equal rights for women. Despite widespread support, the Equal Rights Amendment, or ERA, as it was called, failed to secure ratification in a sufficient number of states. (Subsequent legislation and court decisions, however, gave women in substance what the ERA had been designed to secure.)
