The commitment to defend South Vietnam was reaffirmed by Kennedy on May 11 in National Security Action Memorandum 52, which became known as "The Presidential Program for Vietnam". Its opening statement reads:
U.S. objectives and concept of operations [are] to prevent communist domination of South Vietnam; to create in that country a viable and increasingly democratic society, and to initiate, on an accelerated basis, a series of mutually supporting actions of a military, political, economic, psychological, and covert character designed to achieve this objective.

Promised land reforms were not instituted, and Diem's strategic hamlet program for village self-defense (and government control) was a disaster. The Kennedy administration grew increasingly frustrated with Diệm. In 1963, a crackdown by Diệm's forces was launched against Buddhist monks protesting discriminatory practices and demanding a political voice. Diem's repression of the protests sparked the so-called Buddhist Revolt, during which several monks committed self-immolation, which was covered in the world press. The communists took full advantage of the situation and fueled anti-Diem sentiment to create further instability.

Gulf of Tonkin and the Westmoreland expansion

On July 27, 1964, 5,000 additional U.S. military advisers were ordered to the Republic of Vietnam (RVN or South Vietnam), bringing the total American troop level to 21,000. Shortly thereafter an incident occurred off the coast of the Democratic Republic of Vietnam (North Vietnam) that was destined to escalate the conflict to new levels and lead to the full scale Americanization of the war.

 asking for more political power to utilize American military power in South Vietnam using the attack on the Maddox as cause to get what he wanted.

There was rampant confusion in Washington, but the incident was seen by the administration as the perfect opportunity to present Congress with "a pre-dated declaration of war" by utilizing the incident as an opportunity to strengthen weakening morale in South Vietnam through reprisal attacks by the U.S. on the North. Even before confirmation of the phantom attack had been received in Washington, President Johnson had decided that an attack could not go unanswered.

Just before midnight he appeared on television and announced that retaliatory air strikes were underway against North Vietnamese naval and port facilities. Neither Congress nor the American people learned the whole story about the events in the Gulf of Tonkin until the publication of the Pentagon Papers in 1969. It was on the basis of the administration's assertions that the attacks were "unprovoked aggression" on the part of North Vietnam, that the United States Congress approved the Southeast Asia Resolution (also known as the Gulf of Tonkin Resolution

. U.S. airpower would act as a method of "strategic persuasion", deterring the North Vietnamese politically by the fear of continued or increased bombardment. Rolling Thunder gradually escalated in intensity, with aircraft striking only carefully selected targets. When that did not work, its goals were altered to destroying North Vietnam's will to fight by destroying the nation's industrial base, transportation network, and its (continually increasing) air defenses. After more than a million sorties were flown and three-quarters of a million tons of bombs were dropped, Rolling Thunder was ended on November 11, 1968.

Build-up

President Johnson had already appointed General William C. Westmoreland to succeed General Harkins as Commander of MACV in June 1964. Under Westmoreland, the expansion of American troop strength in South Vietnam took place. American forces rose from 16,000 during 1964 to more than 553,000 by 1969.

. The NLF learned from their defeat and subsequently tried to avoid fighting an American-style ground war by reverting to small-unit guerrilla operations.
The North Vietnamese had already sent units of their regular army into southern Vietnam beginning in late 1964. Some officials in Hanoi had favored an immediate invasion of the South, and a plan was developed to use PAVN units to split southern Vietnam in half through the Central Highlands. The two imported adversaries first faced one another during Operation Silver Bayonet, better known as the Battle of the Ia Drang. During the savage fighting that took place, both sides learned important lessons. The North Vietnamese, who had taken horrendous casualties, began to adapt to the overwhelming American superiority in airmobility, supporting arms, and close air support by moving in as close as possible during confrontations, thereby negating the effects of the above. The Americans learned that PAVN (which was basically a light infantry force) was not a rag-tag band of guerrillas, but was instead a highly disciplined, proficient, and well motivated force.

 declared that if the major operations needed to neutralize North Vietnamese and NLF forces were to succeed, U.S. troop levels in South Vietnam would have to be increased from 120,000 to 400,000. In a series of meetings between Westmoreland and the President held in Honolulu in February 1966, Westmoreland argued that the U.S. presence had succeeded in preventing the immediate defeat of the South Vietnamese government but that more troops would be necessary if systematic offensive operations were to be conducted. The issue then became in what manner American forces would be used.

The nature of the American military's strategic and tactical decisions made during this period would color the conduct and nature of the conflict for the duration of the American commitment. Classical military logic demanded that the U.S. attack the locus of PAVN/NLF in the North. If that country could not be invaded, then the enemy's logistical system in Laos and Cambodia should be cut by ground forces, isolating the southern battlefield. However, political considerations limited U.S. military actions, mainly because of the memory of communist reactions during the Korean War

. Therefore, there would be no invasion of North Vietnam, the "neutrality" of Laos and Cambodia would be respected, and Rolling Thunder would not resemble the bombing of Germany and Japan during the Second World War.
These limitations were not foisted upon the military as an afterthought. Before the first U.S. soldiers came ashore at Da Nang, the Pentagon was cognizant of all of the parameters that would be imposed by their civilian leaders, yet they still agreed that the mission could be accomplished within them. Westmoreland believed that he had found a strategy that would either defeat North Vietnam or force it into serious negotiations. Attrition

American forces would conduct operations against PAVN forces, pushing them further back into the countryside away from the heavily populated coastal lowlands. In the backcountry the U.S. could fully utilize its superiority in firepower and mobility to bleed the enemy in set-piece battles. The cleaning-out of the NLF and the pacification of the villages would be the responsibility of the South Vietnamese military. The adoption of this strategy, however, brought Westmoreland into direct conflict with his Marine Corps

Both sides chose similar strategies. PAVN, which had been operating a more conventional, large-unit war, switched back to small-unit operations in the face of U.S. military capabilities.

s, matched the U.S. at every point of the escalation, funneling manpower and supplies to the southern battlefields.

During the Vietnam War, the use of the helicopter, known as "Air Mobile", was an essential tool for conducting the war. In fact, the whole conduct and strategy of the war depended on it. Vietnam was the first time the helicopter was used on a major scale, and in such important roles. Search and destroy missions, for example, would have been nearly impossible without it. Helicopters allowed American commanders to move large numbers of troops to virtually anywhere, regardless of the terrain or roads. Troops could also be easily resupplied in remote areas. The helicopter also provided another new and vital capability: medical evacuation. It could fly wounded soldiers to aid stations very quickly, usually within the critical first hour. This gave wounded soldiers a higher chance of survival in Vietnam than in any previous war. The helicopter was also adapted for many other roles in Vietnam, including ground attack, reconnaissance, and electronic warfare. Without the helicopter, the war would have been fought very differently.

Border battles and the Tet Offensive

By mid-1967, Westmoreland said that it was conceivable that U.S. forces could be phased out of the war within two years, turning over progressively more of the fighting to the ARVN. That fall, however, savage fighting broke out in the northern provinces. Beginning below the Demilitarized Zone

, large PAVN forces began to stand their ground and fight. This willingness of the communists to remain fixed in place inspired MACV to send reinforcements from other sectors of South Vietnam. The Border Battles had begun.

Most of the PAVN/NLF operational capability was possible only because of the unhindered movement of men along the Ho Chi Minh Trail. To threaten this flow of supplies, the Marine Corps established a combat base on the South Vietnamese side of the Laotian frontier, near the village of Khe Sanh

. The U.S. used the base as a border surveillance position overlooking Route 9, the only east-west road that crossed the border in the province. Westmoreland also hoped to use the base as a jump-off point for any future incursion against the Trail system in Laos. During the spring of 1967, a series of small-unit actions near Khe Sanh prompted MACV to increase its forces. These small unit actions and increasing intelligence information indicated that the PAVN was building up significant forces just across the border.

Indeed, PAVN was doing just that. Two regular divisions (and later elements of a third) were moving toward Khe Sanh, eventually surrounding the base and cutting off its only road access. Westmoreland, contrary to the advice of his Marine commanders, reinforced the outpost. As far as he was concerned, if the communists were willing to mass their forces for destruction by American air power, so much the better. He described the ideal outcome as a "Dien Bien Phu

) to defend Khe Sanh. Another massive aerial effort was undertaken to keep the beleaguered Marines supplied. There were many comparisons (by the media, Americans military and political officials, and the North Vietnamese) to the possibility of PAVN staging a repeat of its victory at Dien Bien Phu, but the differences outweighed the similarities in any comparison.

 was in the process of being field tested in Laos as the siege of Khe Sanh began. Westmoreland ordered that it be employed to detect PAVN troop movements near the Marine base and the system worked well. By March, the long-awaited ground assault against the base had failed to materialize and communist forces began to melt back toward Laos. MACV (and future historians) were left with only questions. What was the goal of the PAVN? Was the siege a real attempt to stage another Dien Bien Phu? Or had the battles near the border (which eventually drew in half of MACV's maneuver battalions) been a diversion, meant to pull forces away from the cities, where another PAVN offensive would soon commence?

General Westmoreland's public reassurances that "the light at the end of the tunnel" was near were countered when, on January 30, 1968, PAVN and NLF forces broke the truce that accompanied the Tết

 holiday and mounted their largest offensive thus far, in hopes of sparking a general uprising among the South Vietnamese. These forces, ranging in size from small groups to entire regiments, attacked nearly every city and major military installation in South Vietnam. The Americans and South Vietnamese, initially surprised by the scope and scale of the offensive, quickly responded and inflicted severe casualties on their enemies. The NLF was essentially eliminated as a fighting force and the places of the dead within its ranks were increasingly filled by North Vietnamese.

The PAVN/NLF attacks were speedily and bloodily repulsed in virtually all areas except Saigon, where the fighting lasted for three days, and in the old imperial capital of Huế

, where it continued for a month. During the occupation of the historic city, 2,800 South Vietnamese were murdered by the NLF in the single worst massacre of the conflict. The hoped-for uprising never took place; indeed, the offensive drove some previously apathetic South Vietnamese to fight for the government. Another surprise for the communists was that the ARVN did not collapse under the onslaught, instead turning in a performance that pleased even its American patrons.

After the Tet Offensive, influential news magazines and newspapers, including the Wall Street Journal, Time and the New York Times, increasingly began to characterize the war as a stalemate. What shocked and dismayed the American public was the realization that either it had been lied to or that the American military command had been dangerously overoptimistic in its appraisal of the situation in Vietnam. The public could not understand how such an attack was possible after being told for several years that victory was just around the corner. The Tet Offensive came to embody the growing credibility gap

Johnson announced that he was limiting bombing of North Vietnam to just north of the Demilitarized Zone and that U.S. representatives were prepared to meet with North Vietnamese counterparts in any suitable place "to discuss the means to bring this ugly war to an end."

 under the slogan that he would end the war in Vietnam and bring "peace with honor." However, there was no plan to do this, and the American commitment continued for another five years.

This policy became the cornerstone of the so-called Nixon Doctrine

 and he was replaced by his deputy, General Creighton W. Abrams. Because of the change in American strategy posed by Vietnamization, Abrams pursued a very different approach. The U.S. was gradually withdrawing from the conflict, and Abrams favored smaller-scale operations aimed at PAVN/NLF logistics, more openness with the media, less indiscriminate use of American firepower, elimination of the body count as the key indicator of battlefield success, and more meaningful cooperation with South Vietnamese forces.

Vietnamization of the war, however, created a dilemma for US forces: the strategy required that US troops fight long enough for the ARVN to improve enough to hold its own against Communist forces. Morale in the US ranks rapidly declined during 1969-1972, as evidenced by declining discipline, worsening drug use among soldiers, and increased "fraggings" of US officers by disgruntled troops.

One of Nixon's main foreign policy goals had been the achievement of a breakthrough in U.S. relations with the People's Republic of China

China and the Soviet Union had been the principal backers of North Vietnam's effort through large-scale military and financial aid. The two communist superpowers had competed with one another to prove their "fraternal socialist links" with the regime in Hanoi. The North Vietnamese had become adept at playing the two nations off against one another. Even with Nixon's rapprochement, their support of North Vietnam increased significantly in the years leading up to the U.S. departure in 1973, enabling the North Vietnamese to mount full-scale conventional offensives against the South, complete with tanks, heavy artillery, and the most modern surface-to-air missile

The Pentagon Papers laid out the missteps taken by four administrations in their Vietnam policies. For example, they revealed the Johnson administration's obfuscations to Congress concerning the Gulf of Tonkin incidents that had led to direct U.S. intervention; they exposed the clandestine bombing of Laos that had begun in 1964; and they detailed the American government's complicity in the death of Ngo Dinh Diem. The study presented a continuously pessimistic view of the likelihood of victory and generated fierce criticism of U.S. policies.

The importance of the actual content of the papers to U.S. policy-making was disputed, but the window that they provided into the flawed decision-making process at the highest levels of the U.S. government opened the issue for other questions. Their publication was a news event and the government's legal (Nixon lost to the Supreme Court

By 1969 the policy of non-alignment and neutrality had worn thin for Prince Sihanouk, ruler of Cambodia.

On March 18, 1970, Sihanouk, who was out of the country on a state visit, was deposed by a vote of the National Assembly and replaced by General Lon Nol. Cambodia's ports were immediately closed to North Vietnamese military supplies, and the government demanded that PAVN/NLF forces be removed from the border areas within 72 hours. Taking advantage of the situation, Nixon ordered a military incursion into Cambodia by U.S. and ARVN troops in order to both destroy PAVN/NLF sanctuaries bordering South Vietnam and to buy time for the U.S. withdrawal. During the Cambodian Campaign, U.S. and ARVN forces discovered and removed or destroyed a huge logistical and intelligence haul in Cambodia.

The incursion also sparked large-scale demonstrations on and closures of American college campuses. The expansion of the conflict into Cambodia was seen as an expansion of the conflict into yet another country, nullifying Nixon's promises of de-escalating the war.

Lam Son 719

In 1971 the U.S. authorized the ARVN to carry out an offensive operation aimed at cutting the Ho Chi Minh Trail in southeastern Laos. Besides attacking the PAVN logistical system (which would buy time for the U.S. withdrawal) the incursion would be a significant test of Vietnamization. Backed by U.S. air and artillery support (American troops were forbidden to enter Laos), the ARVN moved across the border along Route 9, utilizing the abandoned Marine outpost of Khe Sanh as a jumping-off point. At first, the incursion went well, but unlike the Cambodian operation of 1970, the PAVN decided to stand and fight, finally mustering around 60,000 men on the battlefield.

The North Vietnamese first struck the flanks of the ARVN column, smashed its outposts, and then moved in on the main ARVN force. Unlike previous encounters during the conflict, the PAVN fielded armoured formations, heavy artillery, and large amounts of the latest anti-aircraft artillery. After two months of savage fighting, the ARVN retreated back across the border, closely pursued by the North Vietnamese. One half of the invasion force was killed or captured during the operation, and Vietnamization was seen as a failure.

On August 18, Australia and New Zealand decided to withdraw their troops from the conflict. The total number of U.S. forces in South Vietnam dropped to 196,700 on October 29, 1971, the lowest level since January 1966. On November 12, 1971, Nixon set a February 1, 1972 deadline for the removal of another 45,000 troops.

Easter Offensive

Vietnamization received another severe test in the spring of 1972 when the North Vietnamese launched a massive conventional offensive across the Demilitarized Zone. Beginning on March 30, the Easter Offensive (known as the Nguyễn Huệ Offensive to the North Vietnamese) quickly overran the three northernmost provinces of South Vietnam, including the provincial capital of Quảng Trị City. PAVN forces then drove south toward Huế.

Early in April, PAVN opened two additional operations. The first, a three-division thrust supported by tanks and heavy artillery, advanced out of Cambodia on April 5. The North Vietnamese seized the town of Loc Ninh and advanced toward the provincial capital of An Loc in Binh Long Province. The second new offensive, launched from the tri-border region into the Central Highlands, seized a complex of ARVN outposts near Dak To and then advanced toward Kon Tum, threatening to split South Vietnam in two.

The U.S. countered with a buildup of American airpower to support ARVN defensive operations and to conduct Operation Linebacker

, the first offensive bombing of North Vietnam since Rolling Thunder had been terminated in 1968. The PAVN attacks against Huế, An Lộc, and Kon Tum were contained and the ARVN launched a counteroffensive in May to retake the lost northern provinces. On September 10, the South Vietnamese flag once again flew over the ruins of the Citadel of Quảng Trị City, but the ARVN offensive then ran out of steam, conceding the rest of the occupied territory to the North Vietnamese. South Vietnam had countered the heaviest attack since Tet, but it was very evident that it was totally dependent on U.S. airpower for its survival. Meanwhile, the withdrawal of American troops, who numbered less than 100,000 at the beginning of the year, was continued as scheduled. By June only six infantry battalions remained. On August 12, the last American ground combat division left the country. However, the US continued to operate the base At Long Binh. Combat patrols continued there until November 11 when the US handed over the base to the South Vietnamese. After this, only 24,000 American troops remained in Vietnam and President Nixon announced that they would stay there until all US POW's were freed.

At the beginning of the North Vietnamese invasion, the media, including conservative commentator William F. Buckley, predicted the downfall of the Republic of Vietnam; Buckley even called for the firing of General Creighton Abrams

, where he threw several divisions at the entrenched South Vietnamese forces, ultimately losing over half of his army as casualties. General Giap's loss and subsequent retreat was viewed as so great a failure by the North Vietnamese Communist Party that Giap was relieved of his command. Although ARVN troops withstood and repelled the massive PAVN attack at An Lộc, American air power seems to have been a key to the ARVN success, just as it had been a key factor in supporting US ground forces when they operated in South Vietnam prior to 1972. Thus, the 1973 withdrawal of US military support and passage of Congressional resolutions cutting off U.S. funding for combat activities in Indochina (H.R. 9055 and H.J.Res. 636) opened the way for the 1975 defeat of the Republic of Vietnam.

Election of 1972 and Operation Linebacker II

, ran against President Nixon. The president ended Operation Linebacker on October 22 after the negotiating deadlock was broken and a tentative agreement had been hammered out by U.S. and North Vietnamese representatives at the peace negotiations in Paris. The head of the U.S. negotiating team, Henry Kissinger, declared that "peace is at hand" shortly before election day, dealing a death blow to McGovern's already doomed campaign. Kissinger had not, however, counted on the intransigence of South Vietnamese President Thieu, who refused to accept the agreement and demanded some 90 changes in its text. These the North Vietnamese refused to accept, and Nixon was not inclined to put too much pressure on Thieu just before the election, even though his victory was all but assured. The mood between the U.S. and North further turned sour when Hanoi went public with the details of the agreement. The Nixon Administration claimed that North Vietnamese negotiators had used the pronouncement as an opportunity to embarrass the President and to weaken the United States.

 told the press on November 30 that there would be no more public announcements concerning U.S. troop withdrawals from Vietnam since force levels were down to 27,000.

Because of Thieu's unhappiness with the agreement, primarily the stipulation that North Vietnamese troops could remain "in place" on South Vietnamese soil, the negotiations in Paris stalled as Hanoi refused to accept Thieu's changes and retaliated with amendments of its own. To reassure Thieu of American resolve, Nixon ordered a massive bombing campaign against North Vietnam utilizing B-52s and tactical aircraft in Operation Linebacker II

, which began on December 18 with large raids against both Hanoi and the port of Haiphong. Nixon justified his actions by blaming the impasse in negotiations on the North Vietnamese, causing one commentator to describe his actions as "War by tantrum." Although this heavy bombing campaign caused protests, both domestically and internationally, and despite significant aircraft losses over North Vietnam, Nixon continued the operation until December 29. He also exerted pressure on Thieu to accept the terms of the agreement reached in October.

Return to Paris

On January 15, 1973, citing progress in peace negotiations, Nixon announced the suspension of all offensive actions against North Vietnam, to be followed by a unilateral withdrawal of all U.S. troops. The Paris Peace Accords

. Within South Vietnam, a cease-fire was declared (to be overseen by a multi-national, 1,160-man International Control Commission force) and both ARVN and PAVN/NLF forces would remain in control of the areas they then occupied, effectively partitioning South Vietnam. Both sides pledged to work toward a compromise political solution, possibly resulting in a coalition government. To maximize the area under their control, both sides in South Vietnam almost immediately engaged in land-grabbing military operations, which turned into flashpoints. The signing of the Accords was the main motivation for the awarding of the 1973 Nobel Peace Prize

. A separate cease-fire had been installed in Laos in February. Five days before the signing of the agreement in Paris, President Lyndon Johnson, whose presidency had been tainted with the Vietnam issue, died.

The first U.S. prisoners of war were released by North Vietnam on February 11, and all U.S. military personnel were ordered to leave South Vietnam by March 29. As an inducement for Thieu's government to sign the agreement, Nixon had promised that the U.S. would provide financial and limited military support (in the form of air strikes) so that the South would not be immediately overrun. But Nixon was fighting for his political life in the growing Watergate scandal

) was unable to fulfill his promises to Thieu. At the same time, aid to North Vietnam from the Soviet Union increased. With the U.S. no longer heavily involved, both the U.S. and the Soviet Union no longer saw the war as significant to their relations.
