PRESIDENTIAL PROCLAMATION

Overview of Vietnam 1959 to 1975

The Vietnam War was the longest war America ever experienced until recent times. It was the first war, that was televised nightly, focusing on a measure of body count for the day. It was a very political war and by far
                                                                      the most unpopular.

Vietnam War, also known as the Second Indochina War, military struggle fought in Vietnam from 1959 to 1975, involving the North Vietnamese and the National Liberation Front (NLF) in conflict with United States forces and the South Vietnamese army. From 1946 until 1954, the Vietnamese had struggled for their independence from France during the First Indochina War. At the end of this war, the country was temporarily divided into North and South Vietnam. North Vietnam came under the control of Vietnamese Communists who had opposed France and who aimed for a unified Vietnam under Communist rule. The South was controlled by non-Communist Vietnamese.

The United States became involved in Vietnam because American policymakers believed that if the entire country fell under a Communist government, Communism would spread throughout Southeast Asia. This belief was known as the "domino theory." The U.S. government, therefore, helped to create the anti-Communist South Vietnamese government. This government's repressive policies led to rebellion in the South, and in 1960 the NLF was formed with the aim of overthrowing the government of South Vietnam and reunifying the country.

The United States did not want to allow the possibility of Communist control over Vietnam. In June 1954, during the Geneva Conference, the United States pressured Bao Dai to appoint Ngo Dinh Diem prime minister of the government in South Vietnam. The United States chose Diem for his nationalist and anti-Communist credentials. With U.S. support, Diem refused to sign the Geneva Accords. Diem announced he had no intention of participating in the planned national elections, which Ho Chi Minh and the Lao Dong were favored to win. Instead, Diem held elections only in South Vietnam, in October 1955. He won the elections with 98.2 percent of the vote, but many historians believe these elections were rigged, since about 150,000 more people voted in Saigon than were registered. Diem then deposed Bao Dai, who had been the only other candidate, and declared South Vietnam to be an independent nation called the Republic of Vietnam (RVN), with himself as president and Saigon as its capital. Vietnamese Communists and many non-Communist Vietnamese nationalists saw the creation of the RVN as an effort by the United States to interfere with the independence promised at Geneva.

Diem represented the interests of the urban, Catholic minority in South Vietnam. Although Diem also found some support in the countryside among non-Communists, he did not enjoy a broad base of support. The repressive measures of the Diem government, designed to persecute Viet Minh activists and gain control of the countryside, eventually led to increasingly organized opposition within South Vietnam. The United States initially backed Diem's government with military advisers and financial assistance to keep it from collapsing.

When Vietnam was divided in 1954, many Viet Minh who had been born in the southern part of the country returned to their native villages to await the 1956 elections and the reunification of their nation. When the elections did not take place as planned, these Viet Minh immediately formed the core of opposition to Diem's government and sought its overthrow. They were greatly aided in their efforts to organize resistance in the countryside by Diem's own policies, which alienated many peasants.

Beginning in 1955, the United States created the Army of the Republic of Vietnam (ARVN) in South Vietnam. Using these troops, Diem took land away from peasants and returned it to former landlords, reversing the land redistribution program implemented by the Viet Minh. He also forcibly moved many villagers from their ancestral lands to controlled settlements in an attempt to prevent Communist activity, and he drafted their sons into the ARVN.

Diem sought to undermine the Viet Minh, whom he derogatorily referred to as Viet Cong (the Vietnamese equivalent of calling them "Commies"), yet their influence continued to grow. Most southern Viet Minh were committed to the Lao Dong's program of national liberation, reunification of Vietnam, and reconstruction of society along socialist principles. By the late 1950s they were anxious to begin full-scale armed struggle against Diem but were held in check by the northern branch of the party, which feared that this would invite the entry of U.S. armed forces. In 1960, however, widespread opposition to Diem in rural areas convinced the party leadership to officially sanction the formation of the National Front for the Liberation of South Vietnam (commonly known as the National Liberation Front, or NLF). The NLF was a classical Communist-front organization; although Communists dominated the NLF leadership, the organization also embraced non-Communists who opposed the South Vietnamese government. The aim of the NLF was to overthrow the Diem government and reunify Vietnam. Toward this end, the NLF began to train and equip a guerrilla force that was formally organized in 1961 as the People's Liberation Armed Forces (PLAF).

Diem's support was concentrated mainly in the cities. Although he had been a nationalist opposed to French rule, he welcomed into his government those Vietnamese who had collaborated with the French, and many of these became ARVN officers. Catholics were a minority throughout Vietnam, amounting to no more than 10 percent of the population, but they predominated in government positions because Diem himself was Catholic. Between 1954 and 1955, operatives paid by the CIA spread rumors in northern Vietnam that Communists were going to launch a persecution of Catholics, which caused nearly 1 million Catholics to flee to the south. Their resettlement uprooted Buddhists who already deeply resented Diem's rule because of his severe discrimination against them.

In May 1963 Buddhists began a series of demonstrations against Diem, and the demonstrators were fired on by police. At least 7 Buddhist monks set themselves on fire to protest the repression. Diem dismissed these suicides as publicity stunts and promptly arrested 1,400 monks. He then arrested thousands of high school and grade school students who were involved in protests against the government. After this, Diem was viewed as an embarrassment both by the United States and by many of his own generals.

The Saigon government's war against the NLF was also going badly. In January 1963 an ARVN force of 2,000 encountered a group of 350 NLF soldiers at Ap Bac, a village south of Saigon in the Mekong River Delta. The ARVN troops were equipped with jet fighters, helicopters, and armored personnel carriers, while the NLF forces had only small arms. Nonetheless, 61 ARVN soldiers were killed, as were 3 U.S. military advisers. By contrast, the NLF forces lost only 12 men. Some U.S. military advisers began to report that Saigon was losing the war, but the official military and embassy press officers reported Ap Bac as a significant ARVN victory. Despite this official account, a handful of U.S. journalists began to report pessimistically about the future of U.S. involvement in South Vietnam, which led to increasing public concern.

President John F. Kennedy still believed that the ARVN could become effective. Some of his advisers advocated the commitment of U.S. combat forces, but Kennedy decided to try to increase support for the ARVN among the people of Vietnam through counterinsurgency. United States Special Forces (Green Berets) would work with ARVN troops directly in the villages in an effort to match NLF political organizing and to win over the South Vietnamese people.

To support the U.S. effort, the Diem government developed a "strategic hamlet" program that was essentially an extension of Diem's earlier relocation practices. Aimed at cutting the links between villagers and the NLF, the program removed peasants from their traditional villages, often at gunpoint, and resettled them in new hamlets fortified to keep the NLF out. Administration was left up to Diem's brother Nhu, a corrupt official who charged villagers for building materials that had been donated by the United States. In many cases peasants were forbidden to leave the hamlets, but many of the young men quickly left anyway and joined the NLF. Young men who were drafted into the ARVN often also worked secretly for the NLF. The Kennedy administration concluded that Diem's policies were alienating the peasantry and contributing significantly to NLF recruitment.

The number of U.S. advisers assigned to the ARVN rose steadily. In January 1961, when Kennedy took office, there were 800 U.S. advisers in Vietnam; by November 1963 there were 16,700. American airpower was assigned to support ARVN operations; this included the aerial spraying of herbicides such as Agent Orange, which was intended to deprive the NLF of food and jungle cover. Despite these measures, the ARVN continued to lose ground.

As the military situation deteriorated in South Vietnam, the United States sought to blame it on Diem's incompetence and hoped that changes in his administration would improve the situation. Nhu's corruption became a principal focus; Diem was urged to remove his brother, but he refused. Many in Diem's military were especially dissatisfied with Diem's government and the ARVN's inability to rout the NLF, and they hoped for increased U.S. aid. General Duong Van Minh informed the CIA and U.S. ambassador Henry Cabot Lodge of a plot to conduct a coup d'état against Diem. Although the United States wanted to remove Diem from power, it did not give formal support for a coup. When the military generals finally staged the coup on November 1, 1963, it resulted in the murder of both Diem and Nhu. In the political confusion that followed, the security situation in South Vietnam continued to deteriorate. Meanwhile, the CIA was forced to admit that the strength of the NLF was continuing to grow.

Succeeding to the presidency after Kennedy's assassination on November 22, 1963, Lyndon B. Johnson felt he had to take a forceful stance on Vietnam so that other Communist countries would not think that the United States lacked resolve. Kennedy had begun to consider the possibility of withdrawal from Vietnam and had even ordered the removal of 1,000 advisers shortly before he was assassinated, but Johnson increased the number of U.S. advisers to 27,000 by mid-1964. Even though intelligence reports clearly stated that most of the support for the NLF came from the south, Johnson, like his predecessors, continued to insist that North Vietnam was orchestrating the southern rebellion. He was determined that he would not be held responsible for allowing Vietnam to fall to the Communists.

Johnson believed that the key to success in the war in South Vietnam was to frighten North Vietnam's leaders with the possibility of full-scale U.S. military intervention. In January 1964 he approved top-secret, covert attacks against North Vietnamese territory, including commando raids against bridges, railways, and coastal installations. Johnson also ordered the U.S. Navy to conduct surveillance missions along the North Vietnamese coast. He increased the secret bombing of territory in Laos along the Ho Chi Minh Trail, a growing network of paths and roads used by the NLF and the North Vietnamese to transport supplies and troops into South Vietnam. Hanoi concluded that the United States was preparing to occupy South Vietnam and indicated that it, too, was preparing for full-scale war.

On August 2, 1964, North Vietnamese coastal gunboats fired on the destroyer USS Maddox, which had penetrated North Vietnam's territorial boundaries in the Gulf of Tonkin. Johnson ordered more ships to the area, and on August 4^th both the Maddox and the USS Turner Joy reported that North Vietnamese patrol boats had fired on them. Johnson then ordered the first air strikes against North Vietnamese territory and went on television to seek approval from the U.S. public. (Subsequent congressional investigations would conclude that the August 4^th attack almost certainly had never occurred. In 2005 the release of previously classified documents added more support to the finding that the August 4^th attack never occurred. The documents included an account by a National Security Agency (NSA) historian who concluded that NSA intelligence officers "deliberately skewed" the evidence of an attack and failed to pass on information to officials that would have shown that no attack occurred.) The U.S. Congress overwhelmingly passed the Gulf of Tonkin Resolution, which effectively handed over war-making powers to Johnson until such time as 'peace and security' had returned to Vietnam.

After the Gulf of Tonkin incident Johnson declared, "We seek no wider war." United States bombing was significantly reduced. Meanwhile, North Vietnam began to dispatch well-trained units of its People's Army of Vietnam (PAVN) into the south. The NLF guerrillas coordinated their attacks with PAVN forces. On February 7, 1965, the NLF launched surprise attacks on the U.S. helicopter base at Pleiku, killing 8 Americans, wounding 126, and destroying 10 aircraft; on February 10^th they struck again at Qui Nhon, killing 23 U.S. servicemen and wounding 21 at the U.S. enlisted personnel's quarters there. The attacks coincided with two high-level diplomatic visits: one in Hanoi by Soviet premier Aleksey Kosygin, and the other in Saigon by U.S. national security adviser McGeorge Bundy.

Within hours of the attacks, Johnson approved reprisal air strikes against North Vietnam. In Hanoi, Kosygin abandoned his initiative to persuade North Vietnamese leaders to consider negotiations with the United States, and instead promised them unconditional military aid. Johnson's advisers, chiefly Bundy and Defense Secretary Robert McNamara, believed it was imperative to conduct an intensive air campaign against the North, in part to demonstrate it would pay a price for supporting the NLF. Johnson authorized a sustained bombing campaign to begin on March 2^nd. Johnson's senior planners reached the consensus that U.S. combat forces would be required to protect U.S. air bases, as the ARVN was considered to be too weak for the task. On March 8, 1965 the first of these forces, 3,500 U.S. Marines, landed at Da Nang. By the end of April, 56,000 other combat troops had joined them; by June the number had risen to 74,000.

When some of the soldiers of the U.S. 9th Marine Regiment landed in Da Nang in March 1965, their orders were to protect the U.S. air base, but the mission was quickly escalated to include search-and-destroy patrols of the area around the base. This corresponded in miniature to the larger strategy of General William Westmoreland. Westmoreland, who took over the Military Assistance Command in Vietnam (MACV) in 1964, advocated establishing a large American force and then unleashing it in big sweeps. His strategy was that of attrition-eliminating or wearing down the enemy by inflicting the highest death toll possible. There were 80,000 U.S. troops in Vietnam by the end of 1965; by 1969 a peak of about 543,000 troops would be reached.

Having easily pushed aside the ARVN, both the North Vietnamese and the NLF had anticipated the U.S. escalation. With full-scale movement of U.S. troops onto South Vietnamese territory, the Communists claimed that the Saigon regime had become a puppet, not unlike the colonial collaborators with the French. Both the North Vietnamese and NLF appealed to the nationalism of the Vietnamese to rise up and drive this new foreign army from their land.

The strategy developed against the United States was the result of intense debate between the northern and southern members of the Lao Dong's Political Bureau in Hanoi. Truong Chinh, a northerner and the leading Communist ideologist in Hanoi, argued that the southern Vietnamese must liberate themselves, in accordance with a "people's war" strategy that would, if successful, result in a reunified Vietnam; Le Duan, a southerner who became secretary general of the Lao Dong, advocated the North's full support of the armed struggle in the South, on the premise that Vietnam was one nation and therefore dependent on all Vietnamese for its independence and reunification. Ho Chi Minh, revered widely throughout Vietnam as the father of independence, and other party leaders ultimately sided with Duan's point of view. Duan's triumph represented a major turning point within the party in which southerners came to dictate party policy in Hanoi. The Central Committee Directorate for the South (also known as the Central Office for South Vietnam, or COSVN), formed in 1961 as the leadership group of the newly merged southern and central branches of the Lao Dong, was able to coordinate a unified strategy. COSVN was under the direction of Nguyen Chi Thanh, a southerner and a PAVN general, for most of the war.

After the United States initiated large-scale bombing against the Democratic Republic of Vietnam (DRV) in 1964, in the wake of the Gulf of Tonkin incident, Hanoi dispatched the first unit of northern-born regular soldiers to the south. Previously, southern-born Viet Minh, known as regroupees, had returned to their native regions and joined NLF guerrilla units. Now PAVN regulars, commanded by generals who usually had been born in the south, began to set up bases in the Central Highlands of South Vietnam in order to gain strategic position.

Unable to cross the Demilitarized Zone (DMZ) at the 17th parallel separating North from South Vietnam, PAVN regulars moved into South Vietnam along the Ho Chi Minh Trail through Laos and Cambodia. In use since 1957, the trail was originally a series of footpaths; by the late 1960s it would become a network of paved highways that enabled the motor transport of people and equipment. The NLF guerrillas and North Vietnamese troops were poorly armed compared to the Americans, so once they were in South Vietnam they avoided open combat. Instead they developed hit-and-run tactics designed to cause steady casualties among the U.S. troops and to wear down popular support for the war in the United States.

In June 1964 retired general Maxwell Taylor replaced Henry Cabot Lodge as ambassador to South Vietnam. A former chairman of the Joint Chiefs of Staff, the military advisory group to the president, Taylor at first opposed the introduction of American combat troops, believing that this would make the ARVN quit fighting altogether. By 1965 he agreed to the request of General Westmoreland for combat forces. Taylor initially advocated an enclave strategy, where U.S. forces would seek to preserve areas already considered to be under Saigon's control. This quickly proved impossible, since NLF strength was considerable virtually everywhere in South Vietnam.

In October 1965 the newly arrived 1st Cavalry Division of the U.S. Army fought one of the largest battles of the Vietnam War in the Ia Drang Valley, inflicting a serious defeat on North Vietnamese forces. The North Vietnamese and NLF forces changed their tactics as a result of the battle. From then on both would fight at times of their choosing, hitting rapidly, with surprise if possible, and then withdrawing just as quickly to avoid the impact of American firepower. The success of the American campaign in the Ia Drang Valley convinced Westmoreland that his strategy of attrition was the key to U.S. victory. He ordered the largest search-and-destroy operations of the war in the "Iron Triangle," the Communist stronghold in the rural provinces near Saigon. This operation was intended to find and destroy North Vietnam and NLF military headquarters, but the campaign failed to wipe out Communist forces from the area.

By 1967 the ground war had reached a stalemate, which led Johnson and McNamara to increase the ferocity of the air war. The Joint Chiefs of Staff had been pressing for this for some time, but there was already some indication that intensified bombing would not produce the desired results. In 1966 the bombing of North Vietnam's oil facilities had destroyed 70 percent of their fuel reserves, but the DRV's ability to wage the war had not been affected.

Planners wished to avoid populated areas, but when 150,000 sorties per year were being flown by U.S. warplanes, civilian casualties were inevitable. These casualties provoked revulsion both in the United States and internationally. In 1967 the chairman of the Joint Chiefs of Staff, General Earle Wheeler, declared that no more "major military targets" were left. Unable to widen the bombing to population centers for fear of Chinese and Soviet reactions in support of North Vietnam, the U.S. Department of Defense had to admit stalemate in the air war as well. The damage that had already been inflicted on Vietnam's population was enormous.

In 1967 North Vietnam and the NLF decided the time had come to mount an all-out offensive aimed at inflicting serious losses on both the ARVN and U.S. forces. They planned the Tet Offensive with the hope that this would significantly affect the public mood in the United States. In December 1967 North Vietnamese troops attacked and surrounded the U.S. Marine base at Khe Sanh, placing it under siege. Westmoreland ordered the outpost held at all costs. To prevent the Communists from overrunning the base, about 50,000 U.S. Marines and Army troops were called into the area, thus weakening positions further south.

This concentration of American troops in one spot was exactly what the COSVN strategists had hoped would happen. The main thrust of the Tet Offensive then began on January 31, 1968, at the start of Tet, or the Vietnamese lunar new year celebration, when a lull in fighting traditionally took place. Most ARVN troops had gone home on leave, and U.S. troops were on stand-down in many areas. Over 85,000 NLF soldiers simultaneously struck at almost every major city and provincial capital across South Vietnam, sending their defenders reeling. The U.S. Embassy in Saigon, previously thought to be invulnerable, was taken over by the NLF, and held for eight hours before U.S. forces could retake the complex. It took three weeks for U.S. troops to dislodge 1,000 NLF fighters from Saigon.

During the Tet Offensive, the imperial capital of Hue witnessed the bloodiest fighting of the entire war. South Vietnamese were assassinated by Communists for collaborating with Americans; then when the ARVN returned, NLF sympathizers were murdered. United States Marines and paratroopers were ordered to go from house to house to find North Vietnamese and NLF soldiers. Virtually indiscriminate shelling was what killed most civilians, however, and the architectural treasures of Hue were laid to waste. More than 100,000 residents of the city were left homeless.

The Tet Offensive as a whole lasted into the fall of 1968, and when it was over the North Vietnamese and the NLF had suffered acute losses. The U.S. Department of Defense estimated that a total of 45,000 North Vietnamese and NLF soldiers had been killed, most of them NLF fighters. Although it was covered up for more than a year, one horrifying event during the Tet Offensive would indelibly affect America's psyche. In March 1968 elements of the U.S. Army's Americal Division wiped out an entire hamlet called My Lai, killing 500 unarmed civilians, mostly women and children.

After Tet, Westmoreland said that the enemy was almost conquered and requested 206,000 more troops to finish the job. Told by succeeding administrations since 1955 that there was "light at the end of the tunnel," that victory in Vietnam was near, the American public had reached a psychological breaking point. The success of the NLF in coordinating the Tet Offensive demonstrated both how deeply rooted the Communist resistance was and how costly it would be for the United States to remain in Vietnam. After Tet a majority of Americans wanted some closure to the war, with some favoring an immediate withdrawal while others held out for a negotiated peace. President Johnson rejected Westmoreland's request for more troops and replaced him as the commander of U.S. forces in Vietnam with Westmoreland's deputy, General Creighton Abrams. Johnson himself decided not to seek reelection in 1968. Republican Richard Nixon ran for the presidency declaring that he would bring "peace with honor" if elected.

Promising an end to the war in Vietnam, Richard Nixon won a narrow victory in the election of 1968. Slightly more than 30,000 young Americans had been killed in the war when Nixon took office in January 1969. The new president retained his predecessor's goal of a non-Communist South Vietnam, however, and this could not be ensured without continuing the war. Nixon's most pressing problem was how to make peace and war at the same time. His answer was a policy called "Vietnamization." Under this policy, he would withdraw American troops and the South Vietnamese army would take over the fighting.

During his campaign for the presidency, Nixon announced that he had a secret plan to end the war. In July 1969, after he had become president, he issued what came to be known as the Nixon doctrine, which stated that U.S. troops would no longer be directly involved in Asian wars. He ordered the withdrawal of 25,000 troops, to be followed by more, and he lowered draft calls. On the other hand, Nixon also stepped up the Phoenix Program, a secret CIA operation that resulted in the assassination of 20,000 suspected NLF guerrillas, many of whom were innocent civilians. The operation increased funding for the ARVN and intensified the bombing of North Vietnam. Nixon reasoned that to keep the Communists at bay during the U.S. withdrawal, it was also necessary to bomb their sanctuaries in Cambodia and to increase air strikes against Laos.

The DRV leadership, however, remained committed to the expulsion of all U.S. troops from Vietnam and to the overthrow of the Saigon government. As U.S. troop strength diminished, Hanoi's leaders planned their final offensive. While the ARVN had increased in size and was better armed than it had been in 1965, it could not hold its own without the help of heavy U.S. airpower.

Johnson had initiated peace negotiations after the first phase of the Tet Offensive. Beginning in Paris on May 13, 1968, the talks rapidly broke down over disagreements about the status of the NLF, which the Saigon government refused to recognize. In October 1968, just before the U.S. presidential elections, candidate Hubert Humphrey called for a negotiated settlement, but Nixon secretly persuaded South Vietnam's president, Nguyen Van Thieu, to hold out for better terms under a Nixon administration. Stating that he would never negotiate with Communists, Thieu caused the Paris talks to collapse and contributed to Humphrey's defeat as well.

Nixon thus inherited the Paris peace talks, but they continued to remain stalled as each faction refused to alter its position. Hanoi insisted on the withdrawal of all U.S. forces, the removal of the Saigon government, and its replacement through free elections that would include the Provisional Revolutionary Government (PRG), which the NLF created in June 1969 to take over its governmental role in the south and serve as a counterpart to the Saigon government. The United States, on the other hand, insisted that all North Vietnamese troops be withdrawn.

In March 1969 Nixon ordered the secret bombing of Cambodia. Intended to wipe out North Vietnamese and NLF base camps along the border with South Vietnam in order to provide time for the buildup of the ARVN, the campaign failed utterly. The secret bombing lasted four years and caused great destruction and upheaval in Cambodia, a land of farmers that had not known war in centuries. Code-named Operation Menu, the bombing was more intense than that carried out over Vietnam. An estimated 100,000 peasants died in the bombing, while 2 million people were left homeless.

In April 1970 Nixon ordered U.S. troops into Cambodia. He argued that this was necessary to protect the security of American units then in the process of withdrawing from Vietnam, but he also wanted to buy security for the Saigon regime. When Nixon announced the invasion, U.S. college campuses erupted in protest, and one-third of them shut down due to student walkouts. At Kent State University in Ohio four students were killed by panicky national guardsmen who had been called up to prevent rioting. Two days later, two students were killed at Jackson State College in Mississippi. Congress proceeded to repeal the Gulf of Tonkin Resolution. Congress also passed the Cooper-Church Amendment, which specifically forbade the use of U.S. troops outside South Vietnam. The measure did not expressly forbid bombing, however, so Nixon continued the air strikes on Cambodia until August 1973.

Three months after committing U.S. forces, Nixon ordered them to withdraw from Cambodia. The combined effects of the bombing and the invasion, however, had completely disrupted Cambodian life, driving millions of peasants from their ancestral lands. The right-wing government then in power in Cambodia was supported by the United States, and the government was blamed for allowing the bombing to occur. Farmers who had never concerned themselves with politics now flooded to the Communist opposition group, the Khmer Rouge. After a gruesome civil war, the Khmer Rouge took power in 1975 and became one of the bloodiest regimes of the 20th century.

The United States began conducting secret bombing of Laos in 1964, targeting both the North Vietnamese forces along sections of the Ho Chi Minh Trail and the Communist Pathet Lao guerrillas, who controlled the northern part of the country. Roughly 150,000 tons of bombs were dropped on the Plain of Jars in northern Laos between 1964 and 1969. By 1970 at least one-quarter of the entire population of Laos were refugees, and about 400,000 Lao had been killed.

Prohibited by the Cooper-Church Amendment from deploying U.S. troops and anxious to demonstrate the fighting prowess of the improved ARVN, Nixon took the advice of General Creighton Abrams and attempted to cut vital Communist supply lines along the Ho Chi Minh Trail. On February 8, 1971, 21,000 ARVN troops, supported by American B-52 bombers, invaded Laos. Intended to disrupt any North Vietnamese and NLF plans for offensives and to test the strength of the ARVN, this operation was as much a failure as the Cambodian invasion. Abrams claimed 14,000 North Vietnamese casualties, but over 9,000 ARVN soldiers were killed or wounded, while the rest were routed and expelled from Laos.

The success of Vietnamization seemed highly doubtful, since the Communist forces showed that the new ARVN could be defeated. Instead of inhibiting the Communist Pathet Lao, the U.S. attacks on Laos promoted their rise. In 1958 the Pathet Lao had the support of one-third of the population; by 1973 a majority denied the legitimacy of the U.S.-supported royal Lao government. By 1975 a Communist government was established in Laos.

In the spring of 1972, with only 6,000 U.S. combat troops remaining in South Vietnam, the DRV leadership decided the time had come to crush the ARVN. On March 30^th more than 30,000 North Vietnamese troops crossed the DMZ, along with another 150,000 PRG fighters, and attacked Quang Trí Province, easily scattering ARVN defenders. The attack, known as the Easter Offensive, could not have come at a worse time for Nixon and his national security adviser, Henry Kissinger. A military defeat of the ARVN would leave the United States in a weak position at the Paris peace talks and would compromise its strategic position globally.

Risking the success of the upcoming Moscow summit, Nixon unleashed the first sustained bombing of North Vietnam since 1969 and moved quickly to mine the harbor of Haiphong. Between April and October 1972 the United States conducted 41,000 sorties over North Vietnam, especially targeting Quang Trí. North Vietnam's Easter Offensive was crushed. At least 100,000 Communist troops were killed. Vo Nguyen Giap, head of the PAVN and chief military strategist, was perceived as too conservative in his use of force and was compelled to resign. His successor, Van Tien Dung, adopted more aggressive military tactics but also counseled the renewal of negotiations with the United States.

Further negotiations were held in Paris between Kissinger and Le Duc Tho, who represented North Vietnam. Seeking an end to the war before the U.S. presidential elections in November, Kissinger made remarkable concessions. The United States would withdraw completely, while accepting the presence of ten North Vietnamese divisions in South Vietnam and recognizing the political legitimacy of the PRG. Hanoi also made important concessions, such as dropping its insistence on the immediate resignation of Nguyen Van Thieu, who had become president of South Vietnam in 1967. Kissinger announced on October 27 that "peace was at hand." The negotiations had not involved South Vietnam, however, and the Saigon government's acceptance of the terms was not set as a precondition. Thieu was outraged by the agreement, and Nixon subsequently refused to sign it.

After the 1972 elections, Kissinger attempted to revise the agreements he had already made. North Vietnam refused to consider these revisions, and Kissinger threatened to renew air assaults against North Vietnam unless the new conditions were met. Nixon then unleashed at Christmas the final and most intense bombing of the war over Hanoi and Haiphong.

While many U.S. officials were convinced that Hanoi was bombed back to the negotiating table, the final treaty changed nothing significant from what had already been agreed to by Kissinger and Tho in October. Nixon's Christmas bombings were intended to warn Hanoi that American air power remained a threat, and he secretly promised Thieu that the United States would punish North Vietnam should they violate the terms of the final settlement. Nixon's political fortunes were about to decline, however. Although he had won reelection by a landslide in November 1972, he was suffering from revelations about the Watergate scandal. The president's campaign officials had orchestrated a burglary at the Democratic National Committee headquarters, and Nixon had attempted to cover it up by lying to the American people about his role.

The president made new enemies when the secret bombing of Cambodia was revealed at last. Congress was threatening a bill of impeachment and in early January 1973 indicated it would cut off all funding for operations in Indochina once U.S. forces had withdrawn. In mid-January Nixon halted all military actions against North Vietnam.

On January 27, 1973, all four parties to the Vietnam conflict-the United States, South Vietnam, the PRG, and North Vietnam-signed the Treaty of Paris. The final terms provided for the release of all American prisoners of war from North Vietnam; the withdrawal of all U.S. forces from South Vietnam; the end of all foreign military operations in Laos and Cambodia; a cease-fire between North and South Vietnam; the formation of a National Council of Reconciliation to help South Vietnam form a new government; and continued U.S. military and economic aid to South Vietnam. In a secret addition to the treaty Nixon also promised $3.25 billion in reparations for the postwar reconstruction of North Vietnam, an agreement that Congress ultimately refused to uphold.

On March 29, 1973, the last U.S. troops left Vietnam. The Paris peace treaty did little to end the bloodshed for the Vietnamese, however. Problems arose immediately, primarily over the delineation of two separate zones, as required by the agreement, and the mutual withdrawal of troops to these respective zones. Northerners in the Lao Dong leadership wanted to keep hostilities to a minimum in order to keep the United States out of Vietnam. However, southerners on both sides refused to give up the fight. Thieu quickly showed that he had no desire to honor the terms of the treaty. In his view, the continued presence of North Vietnamese soldiers in South Vietnam absolved him of honoring the cease-fire agreement. Thieu immediately began offensives against PRG villages, and he issued an order to the ARVN: "If Communists come into your village...shoot them in the head." In October Hanoi authorized southern Communists to strike back against ARVN troops.

Meanwhile, the withdrawal of U.S. personnel resulted in a collapsing economy throughout South Vietnam. Millions of people had depended on the money spent by Americans in Vietnam. Thieu's government was ill-equipped to treat the mass unemployment and deepening poverty that resulted from the U.S. withdrawal. The ARVN still received $700 million from the U.S. Congress and was twice the size of the Communist forces, but morale was collapsing. More than 200,000 ARVN soldiers deserted in 1974 in order to be with their families.

The apparent weakening of South Vietnam led Hanoi to believe it could win control over the south through a massive conventional invasion, and it set 1975 as the year to mount a final offensive. Hanoi expected the offensive to last at least two years; the rapid collapse of the ARVN was therefore a surprise even to them. After the initial attack by the North Vietnamese in the Central Highlands northeast of Saigon on January 7^th, the ARVN immediately began to fall apart. On March 25^th the ancient imperial city of Hue fell; then on March 29^th, Da Nang, site of the former U.S. Marines headquarters, was overtaken. On April 20^th Thieu resigned, accusing the United States of betrayal. His successor was Duong Van Minh, who had been among those who overthrew Diem in 1963. On April 30^th Minh issued his unconditional surrender to the PRG. Almost 30 years after Ho Chi Minh's declaration of independence, Vietnam was finally unified.

In the United States, military conscription, or the draft, had been in place virtually without interruption since the end of World War II, but volunteers generally predominated in combat units. When the first U.S. combat troops arrived in Vietnam in 1965 they were composed mainly of volunteers. The Air Force, Navy, and Marines were volunteer units. The escalating war, however, required more draftees. In 1965 about 20,000 men per month were inducted into the military, most into the Army; by 1968 about 40,000 young men were drafted each month to meet increased troop levels ordered for Vietnam. The conscript army was largely composed of teenagers; the average age of a U.S. soldier in Vietnam was 19, younger than in World War II or the Korean War. For the first time in U.S. military history, tours of duty were fixed in length, usually for a period of 12 or 13 months, and an individual's date of estimated return from overseas (DEROS) was therefore set at the same time as the assignment date.

Those conscripted were mostly youths from the poorer section of American society. They did not have access to the exemptions that were available to their more privileged fellow citizens. Of the numerous exemptions from military service that Congress had written into law, the most far-reaching were student deferments. The draft laws effectively enabled most upper- and middle-class youngsters to avoid military service. By 1968 it was increasingly evident that the draft system was deeply unfair and discriminatory. Responding to popular pressures, the Selective Service, the agency that administered the draft, instituted a lottery system, which might have produced an army more representative of society at large. Student deferments were kept by Nixon until 1971, however, so as not to alienate middle-class voters. By then his Vietnamization policy had lowered monthly draft calls, and physical exemptions were still easily obtained by the privileged, especially from draft boards in affluent communities.

Both North and South Vietnam also conscripted troops. Revolutionary nationalist ideology was quite strong in the north, and the DRV was able to create an army with well-disciplined, highly motivated troops. It became the fourth-largest army in the world and one of the most experienced. South Vietnam also drafted soldiers, beginning in 1955 when the ARVN was created. Although many ARVN conscripts were committed anti-Communists, the Saigon leadership did little to educate ARVN soldiers on the nature of the war or boost their morale. In 1965, 113,000 deserted from the ARVN; by 1972, 20,000 per month were slipping away from the war.

Although equipped with high-tech weaponry that far exceeded the firepower available to its enemies, the ARVN was poorly led and failed most of the time to check its opponents' actions. United States troops came to dislike and mistrust many ARVN units, accusing them of abandoning the battlefield. The ARVN also suffered from internal corruption. Numerous commanders would claim nonexistent troopers and then pocket the pay intended for those troopers; this practice made some units dangerously understaffed. Some ARVN soldiers were secretly working for the NLF, providing information that undermined the U.S. effort. At various times, battles verging on civil war broke out between troops within the ARVN. Internal disunity on this scale was never an issue among the North Vietnamese troops or the NLF guerrillas.

The armed forces of the United States serving in Vietnam began to suffer from internal dissension and low morale as well. Racism against the Vietnamese troubled many soldiers, particularly those who had experienced racism directed against themselves in the United States. In Vietnam, Americans routinely referred to all Vietnamese, both friend and foe, as "gooks." This process of dehumanizing the Vietnamese led to many atrocities, including the massacre at My Lai, and it provoked profound misgivings among U.S. troops. The injustice of the Selective Service system also turned soldiers against the war. By 1968 coffeehouses run by soldiers had sprung up at 26 U.S. bases, serving as forums for antiwar activities. At least 250 underground antiwar newspapers were published by active-duty soldiers.

After Nixon's troop-withdrawal policy was initiated in 1969, many soldiers became reluctant to risk their lives for a war without a clear purpose. No soldier wished to be the last one killed in Vietnam. Especially toward the end of the war, the fixed one-year tours of duty in Vietnam resulted in a "short-timer" mentality in which combat troops became more reluctant to engage in risky military operations as their departure date approached. In some cases, entire units refused to go out on combat patrols, disobeying direct orders. Soldiers sometimes took out their frustrations and resentments on officers who put their lives at risk, especially officers they deemed to be incompetent or overzealous. The term "fragging" came to be used to describe soldiers attacking their officers, most often by tossing fragmentation grenades into the officers' sleeping quarters. This practice, which took place mostly late in the war, was a clear sign that military discipline had broken down in Vietnam. As the war dragged on and morale sagged within the U.S. armed forces, U.S. military personnel in Vietnam found it increasingly difficult to carry out their service.

Incidents in which soldiers were absent without leave (AWOL) also became more frequent toward the end of the war. Some soldiers who were AWOL for 30 days or more were administratively classified as deserters. Most deserted for personal, rather than political, reasons. Of 32,000 reported deserters who were assigned to combat duty in Vietnam, 7,000 had failed to report for deployment to Vietnam, and 20,000 had completed a full tour of duty in Vietnam but still had obligations of military service; the remaining 5,000 reported desertions occurred in or near Vietnam. Most who went AWOL or deserted later returned or were found, and they received less-than-honorable discharges. Consequently, they received fewer veterans benefits and little, if any, post combat rehabilitation.

Opposition to the war in the United States developed immediately after the Gulf of Tonkin Resolution. Early protests were organized around questions about the morality of U.S. military involvement in Vietnam. Virtually every key event of the war, including the Tet Offensive and the invasion of Cambodia, contributed to a steady rise in antiwar sentiment. The revelation of the My Lai Massacre in 1969 caused a dramatic turn against the war in national polls.

On October 15, 1969, citizens across the United States participated in The Moratorium, the largest one-day demonstration against the war. Millions of people stayed home from work to mark their opposition to the war; college and high school students demonstrated on hundreds of campuses. Vietnam had become a unpopular war with little regard for the troops committed to combat. This dissention was exactly what North Vietnam hoped for, the country had turned bitter towards the war effort and all who participated.

The Vietnam War cost the United States $130 billion directly, and at least that amount in indirect costs, such as veterans' and widows' benefits and the search for Americans missing in action (MIAs). The war spurred serious inflation, contributing to a substantially increased cost of living in the United States between 1965 and 1975. Over 2,600,000 served in Vietnam, with about 1,600,000 experiencing combat or close combat support or regular attacks. Of those who served only 33% were drafted. The peak troop deployment was in 1968 at 543,482, with an average montly draft rate of 40,000. The average infantry man saw 240 days of combat in one year, thanks to the mobility of the helicopter. From 1959 to 1974 58,168 Americans lost their lives in Vietnam, with over 61% of those killed younger than 21. Five men killed in Vietnam were only 16 years old, and the oldest man killed was 62 years old. Although the percentage that died is similar to other wars, amputations or crippling wounds were 300% higher than in World War II. MEDEVAC helicopters flew over 500,000 missions. More than 304,000 U.S. soldiers were wounded, half of them very seriously. There were 2,338 MIAs and 766 POWs (114 died in captivity). No accurate accounting has ever been made of U.S civilians (U.S. government agents, religious missionaries, Red Cross nurses) killed throughout Indochina. There were over 1,248,000 fixed-wing combat sorties flown between 1965 and 1973. There were 6.2 million tons of munitions dropped, three times that of World War II. Over 19 million gallons of rainbow agent herbicides were sprayed over 3.6 million acres of Vietnam, contaminating water shelters.

After returning from the war, many Vietnam veterans suffered from Post-Traumatic Stress Disorder, which is characterized by persistent emotional problems including anxiety and depression. The Department of Veterans Affairs estimated that 20,000 Vietnam veterans committed suicide in the war's aftermath. There are no numbers as to how many Vietnam veterans developed major illness or died, as a result of exposure to herbicides after the war. Throughout the 1970s and 1980s, unemployment and rates of prison incarceration for Vietnam veterans, especially those having seen heavy combat, were significantly higher than in the general population.

Having felt ignored or disrespected both by the Veterans Administration (now the Department of Veterans Affairs) and by traditional organizations such as the Veterans of Foreign Wars and the American Legion, Vietnam veterans have formed their own self-help groups. Collectively, they forced the Veterans Administration to establish storefront counseling centers, staffed by veterans, in every major city. The national organization, Vietnam Veterans of America (VVA), has become one of the most important service organizations lobbying in Washington, D.C.

The Vietnam Veterans Memorial was dedicated in 1982 to commemorate the U.S. personnel who died or were declared missing in action in Vietnam. The memorial, which consists of a V-shaped black granite wall etched with more than 58,000 names, was at first a source of controversy because it does not glorify the military but invites somber reflection. The Asian ancestry of its prizewinning designer, Maya Lin, was also an issue for some veterans. In 1983 a bronze cast was added, depicting one white, one black, and one Hispanic American soldier. This led to additional controversy since some argued that the sculpture muted the original memorial's solemn message. In 1993 a statue of three women cradling a wounded soldier was also added to the site to commemorate the service of the 11,000 military nurses who treated soldiers in Vietnam. Despite all of the controversies, the Vietnam Veterans Memorial has become a site of pilgrimage for veterans and civilians alike.
