Vietnam War

Various names have been applied and shifted over time, though the Vietnam War is the most commonly used in English. It has also been called the Second Indochina War, as it spread to Laos and Cambodia, the Vietnam Conflict, and colloquially Nam. South Vietnam used terms such as () and (). North Vietnam at the time, and official histories produced by the Government of Vietnam today, refer to it as (), or simply the Resistance War against America. Vietnamese both within the country and overseas occasionally refer to it as , the Vietnam War. == Background ==

Vietnam had been under French control as part of French Indochina since the 1880s. Vietnamese independence movements, such as the Vietnamese Nationalist Party, faced suppression despite growing public support for diverse reformist and revolutionary nationalist causes. Nguyen Sinh Cung established the Indochinese Communist Party (ICP) in 1930; the Marxist–Leninist party aimed to overthrow French rule and establish a communist state. Fractures between nationalists and communists emerged in the late 1920s, as the two groups differed in their visions for postcolonial Vietnam: republicanism for the revolutionary nationalists, and proletarian internationalism for the communists. The communists' radical push for centralized control led to a prolonged civil conflict marked by the suppression of rival nationalists, with the ICP largely responsible for initiating systemic Vietnamese-on-Vietnamese violence. Japanese occupation of Indochina In September 1940, Japan invaded French Indochina, following France's capitulation to Nazi Germany. By 1941, Japan had gained full military access across Indochina and established a dual colonial rule that preserved Vichy French administration while facilitating Japanese military operations. Cung, now known as Ho Chi Minh, returned from exile to establish the anti-Japanese Viet Minh movement. Nationalist sentiment, intensified during World War II, helped pave the way for the communist-led Viet Minh, themselves cloaked in nationalism. Following the surrender of Japan, they launched the August Revolution, overthrowing the Japanese-backed state and seizing weapons from the Japanese. On 2 September, Ho Chi Minh declared the independence of the Democratic Republic of Vietnam (DRV). At the same time, following Allied decisions, British forces were deployed to Indochina to oversee the Japanese surrender south of the 16th parallel, while Chinese Nationalist troops did so in the north. On September 23, the British supported a French coup that overthrew the DRV government in Saigon and reinstated French control. O.S.S. forces withdrew as the French sought to reassert control in southern Indochina. First Indochina War (right) as the "supreme advisor" to the government of the Democratic Republic of Vietnam led by president Ho Chi Minh (left), September 1945. Beginning in August 1945, the Viet Minh sought to consolidate power by terrorizing and purging rival Vietnamese nationalist groups and Trotskyist activists. In 1946, the Franco-Chinese and Ho–Sainteny Agreements facilitated a coexistence between the DRV and French that strengthened the Viet Minh while undermining the nationalists. That summer, the Viet Minh colluded with French forces to eliminate nationalists, targeted for their ardent anti-colonialism. With most of the nationalist partisans defeated, and negotiations broken down, tensions between the Viet Minh and French authorities erupted into full-scale war in December 1946, a conflict later drawn into the Cold War. Surviving nationalist partisans and politico-religious groups rallied behind the exiled Bảo Đại to reopen negotiations with France to establish the State of Vietnam in opposition to communist domination. ;Internationalization of war The Chinese communist victory of 1949 transformed the nature of the Indochina War. In January 1950, the People's Republic of China became the first state to recognize the Democratic Republic of Vietnam and persuaded the Soviet Union to do the same. In line with the anticommunist Truman Doctrine, the US and other Western Bloc countries recognized the French-associated State of Vietnam, based in Saigon, as the legitimate government. The civil war and colonial war in Indochina became internationalized, becoming increasingly intertwined with the global Cold War. The outbreak of the Korean War in June convinced Washington policymakers that the war in Indochina was another example of communist expansionism. Within the United States, the Red Scare and rise of McCarthyism fostered public opposition to communism. In April 1950, the Chinese Communist Party formed the Chinese Military Advisory Group (CMAG), marking the beginning of substantial Chinese support for the Viet Minh. Chinese weapons, expertise, and laborers transformed the Viet Minh from a guerrilla force into an army. In September 1950, the US created the Military Assistance Advisory Group (MAAG) to screen French aid requests, advise on strategy, and train Vietnamese soldiers. By 1954, the US had spent $1 billion in support of the French effort, shouldering 80% of the war costs. Battle of Dien Bien Phu In late 1953, the CMAG and the Viet Minh planned operations in northwestern Vietnam around Dien Bien Phu near the Laotian border. In May 1954, the French garrison at Dien Bien Phu surrendered. This marked the end of French military involvement in Indochina. At the Geneva Conference, they negotiated a ceasefire with the Viet Minh, and the independence of Cambodia, Laos, and Vietnam was affirmed, with Vietnam placed under a temporary North–South division. ==Transition period==

At the Geneva Conference, the French and the communists came to see the division of Vietnam into two halves as a necessary solution for reaching a negotiated settlement. However, the United States, represented at the conference by Secretary of State John Foster Dulles, objected to the resolution. The 1954 Geneva Accords produced a flawed peace. Neither the US, nor the State of Vietnam, signed anything at the Geneva Conference. The Diệm government called for UN-supervised elections but rejected those proposed by the Viet Minh, believing they would not be free. During 300 days, up to one million Northerners moved South, including at least 500,000 Catholics, approximately 200,000 Buddhists, and tens of thousands from ethnic minority communities. Allen Dulles, director of the Central Intelligence Agency, authorized a psychological campaign that exaggerated anti-Catholic sentiment among the Viet Minh and circulated materials falsely attributed to them, including claims of an American atomic attack on Hanoi. The CIA's efforts played a minimal role, as Catholic migrants were driven primarily by their own convictions and circumstances rather than external psychological operations. Northern émigrés played a significant role in shaping anticommunist discourse in South Vietnam. Meanwhile, over 100,000 Viet Minh fighters moved North for "regroupment". Between 1953 and 1956, the Northern government instituted agrarian reforms, including rent reduction and land reform, which resulted in political oppression. During land reform, North Vietnamese witnesses suggested a ratio of one execution for every 160 village residents, about 100,000 executions. As the campaign was mainly in the Red River Delta, 50,000 executions became accepted by scholars. However, documents from Vietnamese and Hungarian archives indicate executions were much lower, though likely greater than 14,000. In 1956, leaders in Hanoi admitted to "excesses" and restored much of the land to the original owners. From April to June 1955, Diệm eliminated political opposition in the south by launching operations against religious groups: the Cao Đài and Hòa Hảo of Ba Cụt. The campaign attacked the Bình Xuyên organized crime group, which was allied with members of the communist party secret police and had military elements. The group was defeated in April following a battle in Saigon. As broad opposition to his harsh tactics mounted, Diệm sought to blame the communists. ==Diệm era, 1954–63==

Rule and Secretary of State John Foster Dulles greet President Ngô Đình Diệm of South Vietnam in Washington, 8 May 1957 By virtue of his staunch anticommunism and anticolonialism, Ngô Đình Diệm, an ardent nationalist and devout Catholic, rallied backing from people of varied regional and religious backgrounds, including many Đại Việt partisans and Hòa Hảo, Cao Đài, and Buddhist adherents. Diệm's achievement in transforming the weak South Vietnam into a centralized republic, however, did not guarantee lasting success. His authoritarian tendencies and suppression of alternative views provoked resentment and opposition to his government during the communist insurgency. Diệm launched the "Denounce the Communists" campaign to uncover and arrest communist cadres left behind in the South, 40,000 political prisoners were jailed by 1959. In May 1957, Diệm undertook a 10-day state visit to the US. Eisenhower pledged his continued support, and a parade was held in Diệm's honor. But Secretary of State Dulles privately conceded Diệm had to be backed because they could find no better alternative. Insurgency in the South, 1954–60 At least 50,000 Communist Party members and soldiers with hidden weapon caches were deliberately left in the South following the Geneva Accords in 1954. 17 people were killed in the Châu Đốc massacre at a bar in July. There had been division among former Viet Minh, whose main goal was to hold elections promised in the Geneva Accords, leading to activities separate from the other communists and anti-GVN (Government of the Republic of Vietnam) activists. Douglas Pike estimated that insurgents carried out 2,000 abductions, and 1,700 assassinations of officials, village chiefs, hospital workers and teachers from 1957 to 1960. In September 1960, COSVN, North Vietnam's southern headquarters, ordered a coordinated uprising in South Vietnam and a third of the population was soon living in areas of communist control. In December, North Vietnam formally created the Viet Cong (VC) with the intent of uniting all anti-GVN insurgents, including non-communists. It was formed in Memot, Cambodia, and directed through COSVN. The North Vietnamese Communist Party approved a "people's war" on the South in January 1959, and, in May, Group 559 was established to upgrade the Ho Chi Minh trail, then a six-month mountain trek through Laos. On 28 July, North Vietnamese and Pathet Lao forces invaded Laos, fighting the Royal Lao Army along the border. About 500 of the "regroupees" of 1954 were sent south on the trail during its first year of operation. The first arms delivery was completed in August 1959. In April 1960, North Vietnam imposed military conscription for men. About 40,000 communist soldiers infiltrated the south between 1961 and 1963. ==Kennedy's escalation, 1961–63==

In the 1960 U.S. presidential election, John F. Kennedy defeated Richard Nixon. Although Eisenhower warned Kennedy about Laos and Vietnam, Europe and Latin America "loomed larger than Asia on his sights." Kennedy remained committed to the Cold War foreign policy inherited from the Truman and Eisenhower administrations. In 1961, the US had 50,000 troops based in South Korea, and Kennedy faced four crisis situations: the failure of the Bay of Pigs Invasion he had approved in April, settlement negotiations between the pro-Western government of Laos and the Pathet Lao communist movement in May, construction of the Berlin Wall in August, and the Cuban Missile Crisis in October. Kennedy believed another failure to stop communist expansion would irreparably damage US credibility. He was determined to "draw a line in the sand" and prevent a communist victory in Vietnam. He told The New York Times after the Vienna summit with Khrushchev, "Now we have a problem making our power credible and Vietnam looks like the place." Kennedy's policy toward South Vietnam assumed Diệm and his forces had to defeat the guerrillas on their own. He was against the deployment of American combat troops and observed "to introduce U.S. forces in large numbers there today, while it might have an initially favorable military impact, would almost certainly lead to adverse political and, in the long run, adverse military consequences." The quality of the South Vietnamese military, however, remained poor. Poor leadership, corruption, and political promotions weakened the ARVN. The frequency of guerrilla attacks rose as the insurgency gathered steam. While Hanoi's support for the VC played a role, South Vietnamese governmental incompetence was at the core of the crisis. Kennedy rejected the idea but increased military assistance. In April 1962, John Kenneth Galbraith warned Kennedy of the "danger we shall replace the French as a colonial force...and bleed as the French did." Eisenhower put 900 advisors in Vietnam, and by November 1963, Kennedy had put 16,000. The Strategic Hamlet Program was initiated in late 1961. This joint U.S.–South Vietnamese program attempted to resettle the rural population into fortified villages. It was implemented in early 1962 and involved forced relocation and segregation of rural South Vietnamese, into new communities where the peasantry would be isolated from the VC. It was hoped these new communities would provide security for the peasants and strengthen the tie between them and central government. However, by November 1963 the program had waned, and it ended in 1964. The ARVN lost 83 soldiers and 5 US helicopters, serving to ferry troops shot down by VC forces, while the VC lost only 18 soldiers. The ARVN forces were led by Diệm's most trusted general, Huỳnh Văn Cao. Cao was a Catholic, promoted due to religion and fidelity rather than skill, and his main role was to preserve his forces to stave off coups. Washington policymaker concluded Diệm was incapable of defeating the communists and might even make a deal with Ho Chi Minh. He seemed concerned only with fending off coups and had become paranoid after attempts in 1960 and 1962, which he partly attributed to US encouragement. Robert F. Kennedy noted, "Diệm wouldn't make even the slightest concessions. He was difficult to reason with..." Diệm's alienation of allies who had previously supported his anticommunist efforts, including Buddhist leaders, American officials, and military generals, fueled the unfolding 1963 crisis. US officials began discussing regime change during 1963. The United States Department of State wanted to encourage a coup, while the Pentagon favored Diệm. Chief among the proposed changes was removal of Diệm's brother Nhu, who controlled the secret police and special forces, and was seen as being behind Buddhist repression and the Ngô family's rule. This proposal was conveyed to the US embassy in Saigon in Cable 243. The CIA contacted generals planning to remove Diệm, and told them the US would not oppose this, nor punish them by cutting off aid. Diệm was overthrown and executed, along with his brother, on 2 November 1963. When Kennedy was informed, Maxwell Taylor remembered he "rushed from the room with a look of shock and dismay on his face." Kennedy had not anticipated Diệm's murder. The U.S. ambassador, Henry Cabot Lodge, invited coup leaders to the embassy and congratulated them. Lodge informed Kennedy that "the prospects now are for a shorter war". Kennedy wrote to Lodge congratulating him for "a fine job". Following the coup, chaos ensued. Hanoi took advantage and increased its support for the VC. South Vietnam entered political instability, as one military government toppled another. Each new regime was viewed by the communists as a puppet of the Americans; whatever the failings of Diệm, his credentials as a nationalist had been impeccable. – and "winning the hearts and minds" of the population. Military leadership in Washington, however, was hostile to any role for U.S. advisors other than troop training. General Paul Harkins, the commander of U.S. forces in South Vietnam, confidently predicted victory by Christmas 1963. Paramilitary officers from the CIA's Special Activities Division trained and led Hmong tribesmen in Laos and into Vietnam. The indigenous forces were in the tens of thousands and conducted direct action missions, led by paramilitary officers, against the Communist Pathet Lao forces and their North Vietnamese supporters. The CIA participated in the Military Assistance Command, Vietnam – Studies and Observations Group (MAC-V SOG). Hanoi's road to escalation Within the Politburo of the Workers' Party, since 1960, Lê Duẩn and Nguyễn Chí Thanh had opposed Khrushchev's policy of peaceful coexistence. The opening of the Ho Chi Minh Sea Trail in late 1962, distinct from the land trail through Laos, together with significant increases in the size of the Viet Cong armed forces, gave communist military commanders the capacity to wage a much larger and deadlier campaign in the South. At the same time, the intensification of the Sino-Soviet split during 1963 enabled North Vietnamese leaders to obtain Chinese assurances of support for a more aggressive war approach. Denouncing revisionist Soviet policies, Beijing increasingly endorsed Hanoi's war efforts in South Vietnam. ==Gulf of Tonkin and Johnson's escalation, 1963–69==

Kennedy was assassinated on 22 November 1963. Vice President Lyndon B. Johnson had not been heavily involved with policy toward Vietnam; however he immediately focused on it. On 24 November, he said, "the battle against communism... must be joined... with strength and determination." Johnson knew he had inherited a deteriorating situation, but adhered to the widely accepted domino argument for defending the South: Should they retreat or appease, either action would imperil other nations. Findings from RAND's Viet Cong Motivation and Morale Project bolstered his confidence that an air war would weaken the insurgency. Some argue the policy of North Vietnam was not to topple other non-communist governments in South East Asia. An NSA publication declassified in 2005 revealed there was no attack on 4 August. The second "attack" led to retaliatory airstrikes, and prompted Congress to approve the Gulf of Tonkin Resolution on 7 August. This granted the president power "to take all necessary measures to repel any armed attack against the forces of the United States and to prevent further aggression" and Johnson relied on this as giving him authority to expand the war. Johnson pledged he was not "committing American boys to fighting a war that I think ought to be fought by the boys of Asia to help protect their own land". The National Security Council recommended an escalation of the bombing of North Vietnam. Following an attack on a U.S. Army base in February 1965, airstrikes were initiated, while Soviet Premier Alexei Kosygin was on a state visit to North Vietnam. Operation Rolling Thunder and Operation Arc Light expanded aerial bombardment and ground support operations. The bombing campaign, which lasted three years, was intended to force North Vietnam to cease support for the VC by threatening to destroy North Vietnamese air defenses and infrastructure. It was additionally aimed at bolstering South Vietnamese morale. Between 1965 and 1968, Rolling Thunder deluged the north with a million tons of missiles, rockets and bombs. Bombing of Laos Bombing was not restricted to North Vietnam. Aerial campaigns targeted different parts of the VC and PAVN infrastructure. These included the Ho Chi Minh Trail through Laos and Cambodia. The ostensibly neutral Laos had become the scene of a civil war, pitting the Laotian government backed by the US, against the Pathet Lao and its North Vietnamese allies. Aerial bombardment against the Pathet Lao and PAVN forces was undertaken by the US to prevent the collapse of the government, and deny use of the Ho Chi Minh Trail. Between 1964 and 1973, the US dropped two million tons of bombs on Laos, similar to the 2.1 million tons of bombs it dropped on Europe and Asia during World War II, making Laos the most heavily bombed country in history. The objective of stopping North Vietnam and the VC was never reached. The Chief of Staff of the United States Air Force Curtis LeMay, however, had long advocated saturation bombing in Vietnam and wrote of the communists that "we're going to bomb them back into the Stone Age". The 1964 offensive , June 1965 Following the Tonkin Resolution, Hanoi anticipated the arrival of US troops and expanded the VC, as well as sending PAVN personnel southwards. They were outfitting the VC forces and standardizing their equipment with AK-47 rifles and other supplies, as well as forming the 9th Division. "From a strength of approximately 5,000 at the start of 1959 the Viet Cong's ranks grew to about 100,000 at the end of 1964... Between 1961-64 the Army's strength rose from about 850,000 to nearly a million men." US troop numbers deployed were much lower: 2,000 in 1961, rising to 16,500 in 1964. The use of captured equipment decreased, while more ammunition and supplies were required to maintain regular units. Group 559 was tasked with expanding the Ho Chi Minh Trail, in light of US bombardment. The war had shifted into the final, conventional phase of Hanoi's three-stage protracted warfare model. The VC was tasked with destroying the ARVN, and capturing and holding areas; however, it was not yet strong enough to assault towns and cities. In December 1964, ARVN forces suffered losses at the Battle of Bình Giã, in a battle both sides viewed as a watershed. Previously, the VC had utilized hit-and-run guerrilla tactics. At Binh Gia, they defeated a strong ARVN force in a conventional battle and remained in the field for four days. Tellingly, South Vietnamese forces were again defeated in June 1965 at the Battle of Đồng Xoài. The Marines' initial assignment was defense of Da Nang Air Base. The first deployment was increased to nearly 200,000 by December. With this recommendation, Westmoreland advocated an aggressive departure from America's defensive posture and sidelining of the South Vietnamese. By ignoring ARVN units, the US commitment became open-ended. The plan was approved by Johnson and marked a profound departure from the insistence that South Vietnam was responsible for defeating the VC. Westmoreland predicted victory by December 1967. Johnson did not communicate this change to the media, instead he emphasized continuity. The change in policy depended on matching the North Vietnamese and VC in a contest of attrition and morale. The opponents were locked in an escalation cycle. Westmoreland and McNamara touted the body count system for gauging victory, a metric that proved flawed. The American buildup transformed the South Vietnamese economy and profoundly effected society. South Vietnam was inundated with manufactured goods. Washington encouraged its SEATO allies to contribute troops; Australia, New Zealand, Thailand and the Philippines agreed. South Korea asked to join the Many Flags program in return for economic compensation. Major allies, however, notably Canada and the UK, declined troop requests. The US and allies mounted complex search and destroy operations. In November 1965, the US engaged in its first major battle with the PAVN, the Battle of Ia Drang. The operation was the first large scale helicopter air assault by the US, and first to employ Boeing B-52 Stratofortress bombers. These tactics continued in 1966–67, however, the PAVN/VC insurgents remained elusive and demonstrated tactical flexibility. By 1967, the war had generated large-scale internal refugees, 2 million in South Vietnam, with 125,000 people evacuated and rendered homeless during Operation Masher alone, the largest search and destroy operation to that point. Operation Masher had negligible impact however, as the PAVN/VC returned to the province just four months afterwards. Despite major operations, which the VC and PAVN would evade, the war was characterized by smaller-unit engagements. The VC and PAVN would initiate 90% of large firefights, and thus the PAVN/VC would retain strategic initiative despite overwhelming US force and firepower deployment. internal reports in the Pentagon Papers indicate VC forces retained strategic initiative and controlled their losses. VC attacks against static US positions accounted for 30% of engagements, VC/PAVN ambushes and encirclements for 23%, American ambushes against VC/PAVN forces for 9%, and American forces attacking VC emplacements only 5%. == Tet Offensive and its aftermath ==

In late 1967, the PAVN lured American forces into the hinterlands at Đắk Tô and at the Marine Khe Sanh combat base, where the US fought The Hill Fights. These were part of a diversionary strategy to draw US forces towards the Central Highlands. Preparations were underway for the Tet Offensive, with the intention of Văn Tiến Dũng forces to launch "direct attacks on the American and puppet nerve centers—Saigon, Huế, Danang, all the cities, towns and main bases [...]". Le Duan sought to placate critics of the stalemate by a decisive victory. He reasoned this could be achieved through sparking an uprising in the towns and cities, along with defections among ARVN units, who were on leave during the truce period. The Tet Offensive began in January 1968, as over 100 cities were attacked by over 85,000 VC/PAVN troops, including assaults on military installations, headquarters, and government buildings, including the US Embassy in Saigon. In the Battle of Huế American forces employed massive firepower that left 80% of the city in ruins. In Saigon, VC/PAVN fighters had captured areas in and around the city, attacking key installations before US and ARVN forces dislodged them. Peter Arnett reported an infantry commander saying of the Battle of Bến Tre that "it became necessary to destroy the village in order to save it". During the first month of Tet, 1,100 American and allied troops, 2,100 ARVN and 14,000 civilians were killed. After two months, 5,000 ARVN and 4,000 US forces had been killed and 46,000 wounded. It had become the bloodiest year up to then. The failure to spark a general uprising and lack of defections among the ARVN units meant Hanoi's goals had failed at enormous cost. Prior to Tet, in November 1967, Westmoreland had spearheaded a public relations drive for the Johnson administration to bolster flagging public support. In a speech to the National Press Club he said "the end comes into view". Thus, the public was shocked and confused by the Tet Offensive. Westmoreland and Chairman of the Joint Chiefs of Staff General Earle Wheeler requested more than 200,000 additional troops. This quickly leaked to the media, and the fallout combined with intelligence failures caused Westmoreland to be removed in March 1968, succeeded by his deputy Creighton Abrams. On 10 May 1968, peace talks began between the US and North Vietnam in Paris. Negotiations stagnated for five months, until Johnson halted the bombing of North Vietnam. Hanoi realized it could not achieve a "total victory" and employed a strategy known as "talking while fighting, fighting while talking", in which offensives occurred concurrently with negotiations. Johnson declined to run for re-election as his approval rating slumped from 48% to 36%. His escalation of the war divided Americans, cost 30,000 American lives by that point and is regarded as having destroyed his presidency. Robert McNamara later said "the dangerous illusion of victory by the United States was therefore dead", This was misleading. He was increasing the military pressure on enemy forces, trying to ensure that if the negotiations produced an agreement, it would be one representing a defeat for Hanoi. Johnson did not make the huge increase in US troop strength that Generals Westmoreland and Wheeler had requested a few weeks earlier, but he did send significant reinforcements. There were about 515,000 US military personnel in Vietnam at the time of his speech. There were 536,000 two months later. He narrowed the area of North Vietnam on which US bombs fell, but in April 1968, the first month in which bombing was limited to the southern part of North Vietnam, the United States dropped almost twice as many tons of bombs there as had been dropped on the whole of North Vietnam in March. More importantly, US bombing of Indochina as a whole was increasing. The most the US had dropped in Indochina in any month before Johnson's speech had been about 98,000 tons. In April 1968, the month after his speech, the figure rose to almost 113,000 tons. Vietnam was a major issue during the United States presidential election in 1968. The election was won by Republican Richard Nixon who claimed to have a secret plan to end the war. ==Vietnamization, 1969–72==

Nuclear threats and diplomacy Nixon began troop withdrawals in 1969. His plan to build up the ARVN so it could take over defense of South Vietnam became known as "Vietnamization". As the PAVN/VC recovered from their 1968 losses and avoided contact, Abrams conducted operations aimed at disrupting logistics, with better use of firepower and more cooperation with the ARVN. In October 1969, Nixon had ordered B-52s with nuclear weapons to race to the border of Soviet airspace to convince the Soviets, in accordance with the madman theory, he was capable of anything to end the war. Nixon had sought détente with the Soviet Union and rapprochement with China, which decreased tensions and led to nuclear arms reductions. However, the Soviets continued to supply North Vietnam. Hanoi's war strategy and North Vietnamese to the side of the Republic of Vietnam On 2 September 1969, Ho Chi Minh died. The failure of the Tet Offensive to spark an uprising in the south caused a shift in Hanoi's war strategy, and the Giáp-Chinh "Northern-First" faction regained control over military affairs from the Lê Duẩn-Hoàng Văn Thái "Southern-First" faction. An unconventional victory was sidelined in favor of conventional through conquest. Large-scale offensives were rolled back in favor of small-unit and sapper attacks as well as targeting the pacification and Vietnamization strategy. and the 1969 "Green Beret Affair", where Special Forces soldiers were arrested for the murder of a suspected double agent, provoked outrage. In 1971, the Pentagon Papers were leaked to The New York Times. The secret history of US involvement, commissioned by the Department of Defense, detailed public deceptions by the government. The Supreme Court ruled publication legal. Collapsing U.S. morale Following Tet and decreasing public support, US forces began a period of morale collapse, and disobedience. At home, desertion rates quadrupled from 1966 levels. Among the enlisted, only 2.5% chose infantry between 1969 and 1970. and a low of 33,220 in 1974, depriving the US of much-needed military leadership. Refusal to engage in patrols or carry out orders emerged, with a case of an entire company refusing orders. Unit cohesion began to dissipate and focused on minimizing contact with the PAVN/VC. 900 fragging (killing a fellow officer, usually superior) and suspected fragging incidents were investigated, most occurring between 1969 and 1971. While US forces were redeployed, the ARVN took over combat operations, with casualties double US ones in 1969, and triple in 1970. Post-Tet, membership in the South Vietnamese Regional Forces and Popular Force militias grew, and they could now provide village security, which the Americans had not accomplished. Between 1969 and 1971 the VC and some PAVN units had reverted to small unit tactics, instead of nationwide offensives. In 1971, Australia and New Zealand withdrew their soldiers and US troops were reduced to 196,700, with a deadline to remove another 45,000 troops by February 1972. The US reduced support troops, and in March 1971 the 5th Special Forces Group, the first American unit deployed, withdrew. Cambodia Prince Norodom Sihanouk had proclaimed Cambodia neutral since 1955, but permitted the PAVN/VC to use the port of Sihanoukville and Sihanouk Trail. In March 1969 Nixon launched a secret bombing campaign, called Operation Menu, against communist sanctuaries along the Cambodia/Vietnam border. Only five congressional officials were informed. In March 1970, Sihanouk was deposed by his pro-American prime minister Lon Nol, who demanded North Vietnamese troops leave Cambodia or face military action. Nol began rounding up Vietnamese civilians in Cambodia and massacring them, provoking reactions from the North and South Vietnamese governments. In April–May 1970, North Vietnam invaded Cambodia at the request of the Khmer Rouge, following negotiations with deputy leader Nuon Chea. Nguyen Co Thach recalls: "Nuon Chea has asked for help and we have liberated five provinces of Cambodia in ten days." US and ARVN forces launched the Cambodian campaign in May to attack PAVN/VC bases. A counter-offensive in 1971, as part of Operation Chenla II by the PAVN, recaptured most border areas and decimated Nol's forces. The US incursion into Cambodia sparked U.S. protests as Nixon had promised to deescalate involvement. Students were killed by National Guardsmen in May 1970 at a Kent State University protest, which provoked further outrage. The administration's reaction was seen as callous, reinvigorating the anti-war movement.The war was central to the 1972 U.S. presidential election as Nixon's opponent, George McGovern, campaigned on immediate withdrawal. Nixon's Security Advisor, Henry Kissinger, had continued secret negotiations with North Vietnam's Lê Đức Thọ and in October 1972 reached an agreement. Thiệu demanded changes to the peace accord upon its discovery, and when North Vietnam went public with the details, the Nixon administration claimed they were attempting to embarrass the president. The negotiations became deadlocked when Hanoi demanded changes. To show his support for South Vietnam and force Hanoi back to the negotiating table, Nixon ordered Operation Linebacker II, a bombing of Hanoi and Haiphong in December. Nixon pressured Thiệu to accept the agreement or face military action. On 15 January 1973, all US combat activities were suspended. Lê Đức Thọ and Henry Kissinger, along with the PRG Foreign Minister Nguyễn Thị Bình and a reluctant Thiệu, signed the Paris Peace Accords on 27 January. All US forces personnel were withdrawn by March. ==U.S. exit and final campaigns, 1973–75==

In the lead-up to the ceasefire on 28 January, both sides attempted to maximize land and population under their control in a campaign known as the War of the Flags. Fighting continued after the ceasefire, without US participation, and throughout the year. Gerald Ford took over as US president in August 1974, and Congress cut financial aid to South Vietnam from $1 billion a year to $700 million. Congress voted funding restrictions to be phased in through 1975 and total cutoff in 1976. The success of the 1973–74 dry season offensive inspired Trà to return to Hanoi in October 1974 and plead for a larger offensive the next dry season. This time, Trà could travel on a drivable highway with fueling stops, a vast change from when the Ho Chi Minh Trail was a dangerous mountain trek. Giáp, the North Vietnamese defense minister, was reluctant to approve Trà's plan since a large offensive might provoke US reaction and interfere with the big push planned for 1976. Trà appealed to Giáp's superior, Lê Duẩn, who approved it. Trà's plan called for a limited offensive from Cambodia into Phước Long province. The strike was designed to solve logistical problems, gauge the reaction of South Vietnamese forces, and determine whether the US would return. On 13 December 1974, PAVN forces attacked Phước Long. Phuoc Binh fell on 6 January 1975. Ford desperately asked Congress for funds to assist and re-supply the South before it was overrun. Congress refused. At the start of 1975, the South Vietnamese had three times as much artillery and twice as many tanks and armored vehicles as the PAVN. However, heightened oil prices meant many assets could not be used. Moreover, the rushed nature of Vietnamization, intended to cover US retreat, resulted in lack of spare parts, ground-crew, and maintenance personnel, which rendered most of it inoperable. By the end of April, the ARVN had collapsed except in the Mekong Delta. Refugees streamed southward, ahead of the PAVN onslaught. By 27 April, 100,000 PAVN troops encircled Saigon. The city was defended by about 30,000 ARVN troops. To hasten a collapse and foment panic, the PAVN shelled Tan Son Nhut Airport and forced its closure. Large numbers of civilians had no way out. Fall of Saigon Martial law was declared as American helicopters began evacuating South Vietnamese, US and foreign nationals from Tan Son Nhut and the embassy compound. Operation Frequent Wind had been delayed until the last possible moment, because of Ambassador Graham Martin's belief Saigon could be held and a political settlement reached. Frequent Wind was the largest helicopter evacuation in history. In the morning of 30 April, the last US Marines evacuated the embassy by helicopter, as civilians swamped the perimeter and poured into the grounds. PAVN troops entered Saigon and overcame all resistance, capturing key buildings and installations. Tanks from the 2nd Corps crashed through the gates of the Independence Palace and the VC flag was raised above it. President Dương Văn Minh, who had succeeded Huong two days earlier, surrendered to Lieutenant colonel Bùi Văn Tùng, political commissar of the 203rd Tank Brigade. Minh was escorted to Radio Saigon to announce the surrender. The statement was on air at 2:30 pm. ==Opposition to US involvement==

, an anti-war demonstration organized by the National Mobilization Committee to End the War in Vietnam During the war a large segment of Americans became opposed to US involvement. In January 1967, 32% of Americans thought the US had made a mistake in sending troops. Opinion steadily turned following 1967 and by 1970 60% believed the US had made a mistake. Early opposition drew its inspiration from the Geneva Conference. American support of Diệm in refusing elections was seen as thwarting the democracy that the United States claimed to support. Kennedy, while senator, opposed involvement. and for those involved with the New Left. Others, such as Stephen Spiro, opposed the war based on the theory of Just War. Some wanted to show solidarity with the Vietnamese, such as Norman Morrison emulating Thích Quảng Đức. High-profile opposition increasingly turned to mass protests to shift opinion. Riots broke out at the 1968 Democratic National Convention. After reports of American military abuses brought attention and support to the anti-war movement, some veterans joined Vietnam Veterans Against the War. In October 1969, the Vietnam Moratorium attracted millions. The fatal shooting of students at Kent State University in 1970 led to nationwide university protests. Anti-war protests declined after the Paris Peace Accords and the end of the draft in 1973, and the withdrawal of troops. ==Involvement of other countries==

Pro-Hanoi China China provided significant support for North Vietnam when the US started to intervene, including finance and hundreds of thousands of military support personnel. China said its military and economic aid to North Vietnam totaled $160 billion (adjusted for 2022 prices); China claims to have caused 38% of American air losses. Soviet Union instructors and North Vietnamese crewmen in the spring of 1965 at an air defense training center in Vietnam The Soviet Union supplied North Vietnam with medical supplies, arms, tanks, planes, helicopters, artillery, anti-aircraft missiles and other military equipment. Soviet crews fired Soviet-made surface-to-air missiles at US aircraft in 1965. Following the dissolution of the Soviet Union in 1991, Russia acknowledged that the USSR had stationed up to 3,000 troops in Vietnam. 16 Soviet military personnel were killed in action during the war. Between 1953 and 1991, the hardware donated by the Soviet Union included: 2,000 tanks; 1,700 APCs; 7,000 artillery guns; over 5,000 anti-aircraft guns; 158 surface-to-air missile launchers; and 120 helicopters. The Soviets sent North Vietnam annual arms shipments worth $450 million. From 1965 to 1974, fighting in Vietnam was observed by 11,000 military personnel of the Soviet Armed Forces. The KGB helped develop the signals intelligence capabilities of the North Vietnamese. Pro-Saigon As South Vietnam was formally part of a military alliance with the US, Australia, New Zealand, France, the UK, Pakistan, Thailand and the Philippines, the alliance was invoked during the war. The UK, France and Pakistan declined to participate, and South Korea, Taiwan, and Spain were non-treaty participants. ==United Front for the Liberation of Oppressed Races==

The ethnic minorities of South Vietnam, like the Montagnards in the Central Highlands, the Hindu and Muslim Cham, and the Buddhist Khmer Krom, were actively recruited in the war. There was a strategy of recruitment and favorable treatment of Montagnard tribes by the VC, as they were pivotal for control of infiltration routes. Some groups split off and formed the United Front for the Liberation of Oppressed Races (FULRO) to fight for autonomy or independence. FULRO fought against the South Vietnamese and VC, later fighting against the unified Socialist Republic of Vietnam, after the fall of South Vietnam. ==War crimes==

Both sides committed numerous war crimes including rape, massacring civilians, bombings of civilian targets, terrorism, torture, and summarily executing prisoners of war. Other crimes included theft, arson, and the destruction of property not warranted by military necessity. South Vietnamese, American and South Korean In 1966, the Russell Tribunal was organized by public figures opposed to the war led by Bertrand Russell, to apply the precepts of international law. The tribunal found the US and allies guilty of acts of aggression, use of weapons forbidden by the laws of war, bombardment of targets of a purely civilian character, mistreatment of prisoners, and genocide. Though the tribunal's lack of juridical authority meant findings were ignored by the US and other governments, the hearings contributed to growing evidence which established the factual basis for a counter-narrative to US justifications for the war and inspired hearings, tribunals and legal investigations. In 1968, the Vietnam War Crimes Working Group (VWCWG) was established by the Pentagon task force set up in the wake of the My Lai massacre, to ascertain the veracity of claims of US war crimes. Of the crimes reported to military authorities, sworn statements by witnesses and status reports indicated 320 incidents had a factual basis. The substantiated cases included seven massacres between 1967 and 1971 in which at least 137 civilians were killed; 78 further attacks targeting non-combatants resulting in at 57 deaths and 15 sexually assaulted; and 141 cases of US soldiers torturing civilian detainees, or prisoners of war, with fists, sticks, bats, water or electric shock. Journalists have documented uninvestigated war crimes, involving every active army division, R. J. Rummel estimated that American forces committed around 5,500 democidal killings between 1960 and 1972. Such practice, which involved the assumption that anyone appearing in the designated zones was an enemy that could be freely targeted, was regarded as "a severe violation of the laws of war". Nick Turse argues that a drive toward higher body counts, widespread use of free-fire zones, rules of engagement where civilians who ran from soldiers or helicopters could be viewed as VC and disdain for civilians, led to massive civilian casualties and war crimes. An example cited by Turse is Operation Speedy Express, described by John Paul Vann as "many Mỹ Lais". , which won the 1973 Pulitzer Prize for Spot News Photography, showing a nine-year-old girl running down a road after being severely burned by napalm. Rummel estimated 39,000 were killed by South Vietnam during the Diem-era in democide; for 1964–75, Rummel estimated 50,000 people were killed in democide. Thus, the total for 1954-75 is about 80,000 deaths caused by South Vietnam. The Phoenix Program, coordinated by the CIA, was aimed at destroying the political infrastructure of the VC. The program killed 26,000-41,000 people, an unknown number were innocent civilians. Torture and ill-treatment were frequently applied by the South Vietnamese to POWs, as well as civilian prisoners. During their visit to the Con Son Prison in 1970, congressmen Augustus Hawkins and William R. Anderson witnessed detainees either confined in minute "tiger cages" or chained to their cells, and provided with poor-quality food. American doctors found inmates suffering symptoms resulting from torture. Unlike massacres such as My Lai, media reports of torture of POWs by South Vietnamese and US forces did not generate significant public outcry in the US. South Korean forces were accused of war crimes. One event was the 1968 Phong Nhị and Phong Nhất massacre where the 2nd Marine Brigade reportedly killed about 70 civilians. South Korean forces are accused of perpetrating the Bình Hòa massacre, Binh Tai massacre and Hà My massacre. North Vietnamese and Viet Cong "The overall volume and lethality of Viet Cong terrorism rivals or exceeds all but a handful of terrorist campaigns waged over the last third of the twentieth century", based on the definition of terrorists as a non-state actor, and examining targeted killings and civilian deaths which are estimated at over 18,000 from 1966 to 1969. The Pentagon estimates the VC/PAVN conducted 36,000 murders and 58,000 kidnappings from 1967 to 1972, . Benjamin Valentino attributes 45,000–80,000 "terrorist mass killings" to the VC. and killing 252 Montagnard civilians during the Đắk Sơn massacre. 155,000 refugees fleeing the North Vietnamese Spring Offensive were reported to have been killed, or abducted, on the road to Tuy Hòa in 1975. PAVN/VC troops killed 164,000 civilians in democide between 1954 and 1975 in South Vietnam. North Vietnam was known for its abusive treatment of American POWs, most notably in Hỏa Lò Prison (the Hanoi Hilton), where torture was employed to extract confessions. ==Women==

Women were active in a variety of roles, making significant impacts and the war having significant impacts on them. Several million Vietnamese women served in the military and militias, particularly in the VC, with the slogan "when war comes, even the women must fight" widely used. These women made vital contributions on the Ho Chi Minh Trail, espionage, medical care, logistical and administrative work, and direct combat. Women took on more roles in the economy and Vietnam saw an increase in women's rights. Women emerged as leaders of anti-war campaigns and made significant contributions to war journalism. Women still faced discrimination, and were targets of sexual violence and war crimes. Post-war, Vietnamese women veterans faced difficulty reintegrating into society and having their contributions recognised, as well as advances in rights failing to be sustained. Portrayals of the war have been criticised for their depictions of women, for overlooking the role women played and reducing Vietnamese women to racist stereotypes. Women are at the forefront of campaigns to deal with the war's aftermath, such as the effect of Agent Orange use and the Lai Đại Hàn. ==Black servicemen==

The experience of Black American military personnel has received significant attention. Wallace Terry's work includes observations about the impacts on black servicemen. He notes the higher proportion of combat casualties among African-American servicemen, the shift toward and different attitudes of black military volunteers and conscripts, the discrimination encountered "on the battlefield, in decorations, promotion and duty assignments", as well as having to endure "the racial insults, cross-burnings and Confederate flags of their white comrades"—and the experiences faced by black soldiers stateside, during the war and afterwards. Civil rights leaders protested the disproportionate casualties and overrepresentation in hazardous duty experienced by black servicemen, prompting reforms implemented from 1967. As a result, by the war's completion, black casualties had declined to 13% of combat deaths, about equal to the share of draft-eligible black men, though slightly higher than the 10% who served. ==Weapons==

Nearly all US-allied forces were armed with US weapons including the M1 Garand, M1 carbine, M14 rifle, and M16 rifle. The Australian and New Zealand forces employed the 7.62 mm L1A1 Self-Loading Rifle, with occasional use of the M16 rifle. The PAVN/VC, although having inherited US, French, and Japanese weapons from World War II and the First Indochina War, were largely armed and supplied by China, the Soviet Union, and its Warsaw Pact allies. Some weapons—notably anti-personnel explosives, the K-50M, and "home-made" versions of the RPG-2—were manufactured in North Vietnam. By 1969 the US Army had identified 40 rifle/carbine types, 22 machine gun types, 17 types of mortar, 20 recoilless rifle or rocket launcher types, nine types of antitank weapons, and 14 anti-aircraft artillery weapons used by ground troops on all sides. Also in use, mostly by anti-communist forces, were 24 types of armored vehicles and self-propelled artillery, and 26 types of field artillery and rocket launchers. == Casualties ==

Casualty estimates vary, with one source suggesting up to 3.8 million violent war deaths in Vietnam between 1955 and 2002. It was difficult to distinguish between civilians and military personnel in the VC, as many were part-time guerrillas or impressed laborers who did not wear uniforms and civilians killed were sometimes written off as enemy killed, because high enemy casualties was directly tied to promotions and commendation. Between 275,000 20,000–62,000 Laotians died, ==Aftermath==

In Southeast Asia In Vietnam , its remains have been turned into a war monument. In July 1976, North and South Vietnam were merged to form the Socialist Republic of Vietnam. Despite speculation the victorious North Vietnamese would, in Nixon's words, "massacre the civilians there [South Vietnam] by the millions," no mass executions happened. However many South Vietnamese were sent to re-education camps where they endured torture, starvation, and disease while forced to perform hard labor. The number involved varied depending on different observers: "..."50,000 to 80,000" (Le Monde, 1978), "150,000 to 200,000" (The Washington Post, 1978), and "300,000" (Agence France Presse from Hanoi, 1978)." Such variations are because "Some estimates may include not only detainees but also people sent from the cities to the countryside." According to a native observer, 443,360 people had to register for a period in re-education camps in Saigon alone, and while some were released after a few days, others stayed for more than a decade. Between 1975 and 1980, more than 1 million northerners migrated south, to regions formerly in the Republic of Vietnam, while, as part of the New Economic Zones program, around 750,000 to over 1 million southerners were moved to mountainous forested areas. Gabriel García Márquez described South Vietnam as a "False paradise" when he visited in 1980: The US used its security council veto to block Vietnam's UN recognition three times, an obstacle to it receiving aid. Laos and Cambodia By 1975, the North Vietnamese had lost influence over the Khmer Rouge. Phnom Penh, Cambodia's capital, fell to the Khmer Rouge. Under Pol Pot, the Khmer Rouge would kill 1–3 million Cambodians from a population of 8 million. The relationship between Vietnam and Democratic Kampuchea (Cambodia) deteriorated. In response to the Khmer Rouge taking Phu Quoc and Tho Chu, and the belief they were responsible for the disappearance of 500 Vietnamese natives on Tho Chu, Vietnam launched a counterattack to recover the islands. After failed attempts to negotiate, Vietnam invaded Democratic Kampuchea in 1978 and ousted the Khmer Rouge, in the Cambodian–Vietnamese War. In response, China invaded Vietnam in 1979. The two countries fought the Sino-Vietnamese War. From 1978 to 1979, some 450,000 ethnic Chinese left Vietnam by boat as refugees, or were deported. The Pathet Lao overthrew the monarchy of Laos in 1975, establishing the Lao People's Democratic Republic. The change in regime was "quite peaceful, a sort of Asiatic 'velvet revolution'"—although 30,000 former officials were sent to reeducation camps, often enduring harsh conditions. Former US Air Force official Earl Tilford recounted "repeated bombing runs of a lake in central Cambodia. The B-52s literally dropped their payloads in the lake." The Air Force ran many missions like this to secure additional funding during budget negotiations, so the tonnage expended does not directly correlate with the resulting damage. Unexploded ordnance, mostly from US bombing, continues to kill, and has rendered much land hazardous and impossible to cultivate. Ordnance has killed 42,000 people since the war. In Laos, 80 million unexploded bombs remain. Unexploded ordnance has killed or injured over 20,000 Laotians and about 50 people are killed or maimed annually. It is estimated the explosives will not be removed entirely for centuries. Refugee crisis Over 3 million people left Vietnam, Laos, and Cambodia in the Indochina refugee crisis after 1975. Most Asian countries were unwilling to accept them, many led by boat and were known as boat people. Between 1975 and 1998, an estimated 1.2 million refugees from Vietnam and other Southeast Asian countries resettled in the US, while Canada, Australia, and France resettled over 500,000, China accepted 250,000. Laos experienced the largest flight proportionally, 300,000 out of a population of 3 million crossed the border into Thailand. Included among them were "about 90%" of Laos' "intellectuals, technicians, and officials." In the United States private waits on the beach during the Marine landing, Da Nang, 3 August 1965 Failure of US goals is placed at different institutions and levels. Some have suggested it was due to failure of leadership. Others point to military doctrine. Secretary of Defense Robert McNamara stated that "the achievement of a military victory by U.S. forces...was indeed a dangerous illusion." General William Westmoreland admitted bombing had been ineffective, saying he doubted "that the North Vietnamese would have relented." The Vietnam War POW/MIA issue, concerning the fate of US service personnel missing in action, persisted. The costs loom large in American consciousness; a 1990 poll showed the public incorrectly believed more Americans died in Vietnam than World War II. Financial cost Between 1953 and 1975, the US was estimated to have spent $168 billion on the war (equivalent to $ trillion in ). This resulted in a large budget deficit. Other figures point to $139 billion from 1965 to 1974 (not inflation-adjusted), 10 times education spending, and 50 times more than housing and community development. It was stated that war-spending could have paid every mortgage in the US, with money leftover. Impact on the U.S. military More than 3 million Americans served, 1.5 million saw combat. "At the height of American involvement in 1968, for example, 543,400 American military personnel were stationed in Vietnam, but only 80,000 were...combat troops." Conscription existed since World War II, but ended in 1973. 58,220 American soldiers were killed, The average age of troops killed was 23. Approximately 830,000 veterans, 15%, suffered posttraumatic stress disorder. Drug use, racial tensions, and fragging—attempts to kill officers—created problems for the military and impacted its capability. 125,000 Americans left for Canada to avoid the draft, and approximately 50,000 servicemen deserted. In 1977, President Jimmy Carter granted an unconditional pardon to Vietnam draft evaders with Proclamation 4483. The war called into question army doctrine. Marine general Victor H. Krulak criticized Westmoreland's attrition strategy, calling it "wasteful of American lives... with small likelihood of a successful outcome." Effects of U.S. chemical defoliation s in the Mekong Delta, South Vietnam, 1969 Another controversial aspect of the US effort was use of chemical defoliants between 1961 and 1971. 20 million gallons of toxic herbicides, like Agent Orange, were sprayed on 6 million acres of forests and crops. They were used to defoliate parts of the countryside to prevent the VC from hiding weaponry and encampments, and deprive them of food. Defoliation was used to clear sensitive areas, including base perimeters and ambush sites along roads and canals. including suppressing the growth of some plants and crops and proceeding into the sediment, affecting fish and other species. US records have listed figures including the destruction of 20% of the jungles of South Vietnam and 20-36% of the mangrove forests. The environmental destruction caused was described by Swedish Prime Minister Olof Palme, lawyers, and academics as an ecocide. The chemicals in Agent Orange pose health hazards, such as immune system disorders, developmental abnormalities, and issues with the reproductive system. Agent Orange and similar substances have caused many health issues for Vietnamese people and the US crews that handled them. Reports concluded that refugees exposed to sprays continued to experience pain in the eyes, skin and gastrointestinal upsets. In one study, 92% of participants suffered incessant fatigue; others reported monstrous births. Analysis has found significant correlation between having a parent who was exposed to Agent Orange with the likelihood of possessing or acting as a carrier of birth defects. The most common deformity appears to be spina bifida. There is substantial evidence defects carry on for three generations or more. In 2012, the US and Vietnam cooperated in cleaning toxic chemicals on Da Nang International Airport, marking the first time Washington has been involved in cleaning up Agent Orange in Vietnam. In 2018, Vietnam treated 150,000 cubic meters of contaminated soil. , 2004 Vietnamese victims attempted a class action lawsuit against Dow Chemical and other US chemical manufacturers, but a US District Court dismissed their case. , the Vietnamese government estimated there were over 4,000,000 victims of dioxin poisoning in Vietnam, while the Vietnamese Red Cross estimates up to one million people have health problems or disabilities as a result of Agent Orange. The US has described these figures as unreliable, The US Veterans Administration has listed prostate cancer, respiratory cancers, multiple myeloma, type 2 diabetes, B-cell lymphomas, soft-tissue sarcoma, chloracne, porphyria cutanea tarda, peripheral neuropathy as, "presumptive diseases associated with exposure to Agent Orange or other herbicides during military service." Spina bifida is the sole birth defect in children of veterans recognized as caused by exposure to Agent Orange. In popular culture . The original statue was demolished after April 1975. The war has featured extensively in television, film, video games, music and literature. In Vietnam, the Girl from Hanoi (1974) was a film set during Operation Linebacker II, depicting wartime life. Another notable work was the diary of Đặng Thùy Trâm, a doctor who enlisted in the Southern battlefield, and was killed aged 27 by US forces. Her diaries were published in Vietnam as ''Đặng Thùy Trâm's Diary (Last Night I Dreamed of Peace), where it became a bestseller and was made into a film Don't Burn. The diary has been compared to The Diary of Anne Frank'', and used in education. The first major film on the war was John Wayne's pro-war The Green Berets (1968). Further films were released, the most noteworthy examples being Michael Cimino's The Deer Hunter (1978), Francis Ford Coppola's Apocalypse Now (1979), Oliver Stone's Platoon (1986) and Stanley Kubrick's Full Metal Jacket (1987). Other films include Good Morning, Vietnam (1987), Casualties of War (1989), and Born on the Fourth of July (1989). The war influenced a generation of musicians and songwriters, pro/anti-war and pro/anti-communist. The Vietnam War Song Project has identified 5,000+ songs referencing the conflict. Country Joe and the Fish recorded ''The "Fish" Cheer/I-Feel-Like-I'm-Fixin'-to-Die Rag'' in 1965, and it became one of the most influential protest anthems. attacking orthodox and revisionist schools of historiography, and challenging myths about American society and soldiery in the war. in particular the notion that the Mỹ Lai massacre was caused by drug use. According to Kuzmarov, Nixon is primarily responsible for creating the drug myth. Michael Allen accuses Nixon of mythmaking, by exploiting the plight of the National League of POW/MIA Families to allow the government to appear caring, as the war was increasingly considered lost. Allen's analysis ties the position of potential missing Americans, or prisoners into post-war politics and presidential elections, including the Swift boat controversy. ==See also==
