Ngo Dinh Diem

On 21 July 1954, the Geneva Accords temporarily partitioned Vietnam at the 17th parallel, pending elections in July 1956 to reunify the country. The Democratic Republic of Vietnam controlled the north, while the French-backed State of Vietnam controlled the south with Diệm as the Prime Minister. Diệm criticized the French for abandoning North Vietnam to the Communists at Geneva, claimed that the terms did not represent the will of the Vietnamese people, and refused French suggestions to include more pro-French officials in the government.[49]

The Geneva Accords allowed for freedom of movement between the two zones until October 1954; this put a large strain on the south. Diệm had only expected 10,000 refugees, but by August, there were more than 200,000 waiting for evacuation from Hanoi and Hải Phòng. Nevertheless, the migration helped to strengthen Diệm's political base of support as the refugees were strongly anti-communist. To deal with the refugee situation, Diem's government arranged for their relocation into fertile and under-populated provinces in the western Mekong Delta. The Diệm regime also provided them with food and shelter, farm tools, and housing materials as well as digging irrigation canals, building dykes, and dredging swamp-lands to help stabilise their lives.[50]

In August 1954, Diệm also had to face the "Hinh crisis" when Hinh launched a series of public attacks on Diem, proclaiming that South Vietnam needed a “strong and popular” leader, as well as threatening to coup. However, at the end of 1954, Diệm successfully forced Hinh to resign from his post. Hinh had to flee to Paris and hand over his command of the national army to General Nguyễn Văn Vy.[51] But the National Army officers favoured Diệm's leadership over General Vy, which forced him to flee to Paris.[52] Despite the failure of Hinh's alleged coup, the French continued to encourage Diệm's enemies in an attempt to destabilize him.[51]

On 31 December 1954, Diệm established the National Bank of Vietnam and replaced the Indochinese banknotes with new Vietnamese banknotes.[53] In early 1955, although American advisors encouraged Diệm to negotiate with the leaders of the political-religious forces who threatened to overthrow his position and to forge an anti-communist bloc, he was determined to attack his enemies to consolidate his power.[54] In April 1955, Diệm's army forces took most of Bình Xuyên's posts in Saigon after a victory in the Battle of Saigon. Within a few months, Diệm's troops wiped out the Bình Xuyên's remnants, leaving only a few small bands, who then joined forces with the communists.

The defeat of Bình Xuyên increased the authority and prestige of Diệm's government and marked the end of French efforts to remove Diệm.[55] Most of the Cao Đài leaders chose to rally to Diệm's government.[56] Diệm then dismantled the private armies of the Cao Đài and Hòa Hảo religious sects. By the end of 1955, Diệm had almost taken control of South Vietnam, and his government was stronger than ever before.[57] In April 1956, along with the capture of Ba Cụt, the leader of the last Hòa Hảo rebels, Diệm almost subdued all of his non-communist enemies, and could focus on his Vietnamese communist opponents.[58] According to Miller, Diệm's capacity in subduing his enemies and consolidating his power strengthened U.S. support of his government, although the U.S. government had planned to withdraw its backing from Diệm during his early difficult years of leadership.[59]

Results of the 1955 referendum posted on Saigon City Hall

In South Vietnam, a referendum was scheduled for 23 October 1955 to determine the future direction of the south, in which the people would choose Diệm or Bảo Đại as the leader of South Vietnam.[60] Diem, with the support of his brother Ngô Đình Nhu and the Cần Lao Party, used an avid propaganda campaign to destroy Bao Dai's reputation and garner support for Diem. Supporters of Bảo Đại were not allowed to campaign, and were physically attacked by Nhu's workers.[61] Official results showed 98.2 per cent of voters favoured Diệm, an implausibly high result that was condemned as fraudulent. The total number of votes far exceeded the number of registered voters by over 380,000, further evidence that the referendum was heavily rigged.[61][62] For example, only 450,000 voters were registered in Saigon, but 605,025 were said to have voted for Diệm.[61][62]

Representatives meeting at the 1954 Geneva Accords

On 26 October 1955, Diệm proclaimed the formation of the Republic of Vietnam, with himself as its first President until 26 October 1956. The first Constitution provided articles to establish the republic and organize the election of its president.[63] The 1954 Geneva Accords prescribed elections to reunify the country in 1956. Diệm refused to hold these elections, claiming that a free election was not possible in the North[64] and that since the previous State of Vietnam had not signed the accords, they were not bound by it[65] – despite having been part of the French Union,[66] which itself was bound by the Accords.[67] According to historian Keith Taylor, Diệm's rejection of the Geneva accords was a way of objecting to the French colonization of Vietnam and his disposition of Bảo Đại and the establishment of the First Republic of Vietnam was a way to claim Vietnamese independence from France.[68] At the same time, the first Constitution of the Republic of Vietnam was promulgated. According to the Constitution, Diệm as president vested a huge amount of power, and his governance style became increasingly authoritarian over time.[69]

Diệm's rule was authoritarian and nepotistic. His most trusted official was Nhu, leader of the primary pro-Diệm Can Lao political party, who was an opium addict and admirer of Adolf Hitler. He modeled the Can Lao secret police's marching style and torture styles on Nazi designs.[70] Cẩn was put in charge of the former Imperial City of Huế. Although neither Cẩn or Nhu held any official role in the government, they ruled their regions of South Vietnam, commanding private armies and secret police. Diệm's youngest brother Luyện, was appointed Ambassador to the United Kingdom. His elder brother, Ngô Đình Thục, was Archbishop of Huế. Despite this, Thuc lived in the Presidential Palace, along with Nhu, Nhu's wife and Diệm. Diệm was nationalistic, devoutly Catholic, anti-Communist, and preferred the philosophies of personalism and Confucianism.[71][72]

Diệm's rule was also pervaded by family corruption. Can was widely believed to be involved in illegal smuggling of rice to North Vietnam on the black market and opium throughout Asia via Laos, as well as monopolizing the cinnamon trade, amassing a fortune stored in foreign banks.[73][74] With Nhu, Can competed for U.S. contracts and rice trade.[75] Thuc, the most powerful religious leader in the country, was allowed to solicit "voluntary contributions to the Church" from Saigon businessmen, which was likened to "tax notices".[76] Thuc also used his position to acquire farms, businesses, urban real estate, rental property and rubber plantations for the Catholic Church. He also used Army of the Republic of Vietnam personnel to work on his timber and construction projects. The Nhus amassed a fortune by running numbers and lottery rackets, manipulating currency and extorting money from Saigon businesses while Luyen became a multimillionaire by speculating in piasters and pounds on the currency exchange using inside government information.[77]

However, Miller wrote that Diệm also clamped down on corruption. South Vietnam was divided into colonial-era provinces, of which governors enjoyed sweeping powers and firmly controlled local administrations, creating a problem of corruption and cronyism. The governors were seen as petty tyrants, and Diệm launched corruption probes while also replacing many of the governors. However, starting in 1954, the political turmoil prevented him from taking further measures.[78] The MSUG, an American advisory body created to aid the Diệm's regime, recommended that Diệm centralize power by abolishing local administrations and reforming the existing ones into much larger "areas", with much less power and no financial autonomy. Diệm objected to abolishing the position of province chiefs, arguing that only local governments could address "the needs of local people" as he believed that requiring fiscal self-sufficiency from the local governments was key to creating the "ethos of mutual responsibility" – a key concept in Diệm's communitarian interpretation of democracy.[79]

The Can Lao Party played a key role in Diệm's regime. Initially, the party acted secretly based on a network of cells, and each member only knew the identities of a few other members. When necessary, the Party could assume the role of the government. After 1954, the existence of the party was recognized, but its activities were hidden from public view. In the early 1950s, Diệm and Nhu used the party to mobilize support for Diệm's political movements. According to the decree 116/BNV/CT of the Republic of Vietnam, the Can Lao Party was established on 2 September 1954. Personalism, as part of Person Dignity Theory, officially became the basic doctrine of Diệm's regime since the Constitution's preface declared that "Building Politics, Economy, Society, Culture for the people based on respecting Personalism".[80]

According to Miller, democracy, to Diệm, was rooted in his dual identity as Confucian and Catholic, and was associated with communitarianism and the doctrine of Personalism. He defined democracy as "a social ethos based on certain sense of moral duty", not in the U.S. sense of "political right" or political pluralism and in the context of an Asian country like Vietnam, Confucian and Catholic values were relevant to deal with contemporary problems in politics, governance, and social change. In this sense, Diệm was not a reactionary mandarin lacking an interest in democracy as he has been portrayed by some scholars. His way of thinking about democracy became a key factor of his approach to political and administrative reform.[81] Diệm argued that post-colonial Vietnam must be a democratic country, but noted that Vietnamese democracy should develop out of its precolonial models, rather than European and American concepts, arguing that Vietnamese "institutions, customs and the principles underlying them are democratic facts."[82] Researching the Nguyễn dynasty, Diệm asserted that the moral norm of Nguyễn-era Vietnam was that it was founded "on the people", following the Confucian concept of Mandate of Heaven; people could and often did withdraw their support from unpopular monarchs, causing their downfall. Diệm considered it an "indigenous Vietnamese democratic tradition" and wished to make it the basis of democracy that would emerge in Vietnam.[83]

Diệm's ideology of personalism was largely influenced by the Confucian notion that self-improvement meant cooperation with one's local community and society at large; he thought that there is a tension between individual's personal ambitions and community's ethos of mutual responsibility. Inspired by the writings of Catholic philosopher Emmanuel Mounier, Diệm considered his ideology of personalism a "third way" of communitarianism, presenting an alternative to both individualism and collectivism, insisting that democracy couldn't be realised "by drafting and promulgating documents and regulations", but that civil liberties granted by democratic regime to its citizens should serve "collective social improvement", serving each person's community rather than the individual itself.[84] In 1955, Diệm wrote that "democracy is primarily a state of mind, a way of living that respects the human person, both with regard to ourselves and with regard to others" and that "more than any other form of government, democracy demands that we all display wisdom and virtue in our dealings with each other." In 1956, Diem added that democracy had to foster a feeling of community and mutual responsibility, arguing that respect for democracy lays in "decency in social relations", thus defining Vietnamese democracy as inherently communitarian and not individualist.[83]

Diệm taking the oath as First President of the Republic of Vietnam

In summer and fall of 1955, Diệm's administration had to decide the fate of the former emperor Bảo Đại. Bảo Đại was initially supposed to remain the head of state until the National Assembly elections, but Diệm's cabinet decided to decide the monarch's fate through a referendum. Miller highlights that despite the popular belief that the referendum was put forward by Edward Lansdale, it was Diệm who decided to organise the referendum as a way to burnish his democratic credentials and attempt to realise his democratic ideas. While the monarch was highly unpopular given his collaboration with the French colonial regime, the new government committed to further diminishing Đại's reputation with aggressive smear campaign and large pro-rallies. Additionally, the referendum itself was considered non-secret, given that the voters were given ballots with the photos of Diệm and Bảo Đại on it and were supposed to tear it in half and deposit the slice with their preferred candidate into the box – this made one's choice visible to everyone.[85] Miller notes that the referendum reveals the eccentric nature of Diệm's understanding of democracy – in the sense of political pluralism, the vote appeared inherently authoritarian; but to Diệm his margin appeared legitimate, as he described democracy as "state of mind" in which the people elect the morally superior leader. Thus Diệm was "adamant that the outcome was entirely consistent with his view of democracy as the citizenry's embrace of a common moral ethos".[86]

On 4 March 1956, the elections for the first National Assembly were held. These elections were considerably more free and fair than the referendum, and some governmental candidates would highly contest with independents and oppositionist candidates for their seats, according to Miller. On this occasion, non-government candidates were allowed to campaign and the election had an atmosphere of legitimate pluralism, but the government retained the right to ban candidates deemed to be linked to the communists or other 'rebel' groups, and campaign material was screened. However, Miller notes that in some districts the opposition candidates withdrew due to police intimidation and military presence.[87] Surprisingly, instead of letting the draft constitution be created by a handpicked commission, Diệm dissolved it and had the constitution be made by the National Assembly deputies instead. The government hailed the process as democratic and transparent, given how the Assembly meetings were open and media presence was allowed; the National Revolutionary Movement dominated the council, but a handful of opposition figures had won seats as well.[63]

However, Diệm's regime of "democratic one man rule" faced increasing difficulties. After coming under pressure from within Vietnam and from the United States, Diệm agreed to hold legislative elections in August 1959 for South Vietnam. However, in reality, newspapers were not allowed to publish names of independent candidates or their policies, and political meetings exceeding five people were prohibited. Candidates who ran against government-supported opponents faced harassment and intimidation. In rural areas, candidates who ran were threatened using charges of conspiracy with the Việt Cộng, which carried the death penalty. Phan Quang Đán, the government's most prominent critic, was allowed to run. Despite the deployment of 8,000 ARVN plainclothes troops into his district to vote, Đán still won by a ratio of six to one. The busing of soldiers to vote for regime approved candidates occurred across the country. When the new assembly convened, Đán was arrested.[88]

Diệm with U.S. Vice President Lyndon B. Johnson and Ambassador Frederick Nolting in 1961

In May 1961, U.S. Vice President Lyndon B. Johnson visited Saigon and enthusiastically declared Diệm the "Winston Churchill of Asia". When asked why he had made the comment, Johnson replied, "Diệm's the only boy we got out there." Johnson assured Diệm of more aid in molding a fighting force that could resist the communists.[89]

During his presidency, Diệm imposed programs to reform Saigon society in accordance with Catholic and Confucian values. Brothels and opium dens were closed, divorce and abortion were made illegal, and adultery laws were strengthened.[90] Additionally, Diệm's government established many schools and universities, such as the National Technical Center at Phú Thọ in 1957, the University of Saigon (1956), the University of Hue (1957), and the University of Dalat (1957).[91]

Diệm hoped to develop a national, revolutionary spirit within the citizens of South Vietnam as well as a vibrant communal democracy and an independent, non-communist Vietnam. He saw the peasantry as the key to this nation-building as he believed the peasantry was more likely to put the country before their own self interest in a spirit of volunteerism. A Special Commissariat for Civic Action was established to extend the reach of the Saigon government into rural areas and to help create 'model villages' to show rural peasants that the South Vietnamese government was viable as well as allowing citizen volunteers, and experts, to help these communities develop and tie them to the nation. The Special Commissariat for Civic Action was considered a practical tool of Diệm's government to serve "the power vacuum", and be a force of influence for Diệm's government, in the rural countryside following the departure of Việt Minh cadres after the Geneva Accords (1954).[92]

Geoffrey C. Stewart's study provides a clearer picture of Diệm's domestic policies and a further understanding of his government's efforts in reaching and connecting with local communities in South Vietnam that shows "an indigenous initiative" of the government in building an independent and viable nation.[92]

Land Reform In South Vietnam, especially in Mekong Delta, landholdings in rural areas were concentrated in small number of rich landlord families. Thus, it was urgent to implement land reform in South Vietnam. Diệm had two attempts to control the excesses of the land tenancy system by promulgating the Ordinance 2 on 28 January 1955 to reduce land rent between 15% and 25% of the average harvest and the Ordinance 7 on 5 February 1955 to protect the rights of tenants on new and abandoned land and enhancing cultivation. In October 1956, with the urge from Wolf Ladejinsky, Diệm's personal adviser on agrarian reform, Diệm promulgated a more serious ordinance on the land reform, in which he proclaimed a "land to the tiller" (not to be confused with other Land reform in South Vietnam like Nguyễn Văn Thiệu's later 'Land to the Tiller" program) program to put a relatively high 100 hectares limit on rice land and 15 hectares for ancestral worship.[93] However, this measure had no real effect because many landlords evaded the redistribution by transferring the property to the name of family members. Besides, during the 1946–54 war against the French Union forces, the Việt Minh had gained control of parts of southern Vietnam, initiated land reform, confiscated landlords' land and distributed it to the peasants.[94] Additionally, the ceiling limit was more than 30 times that allowed in Japan, South Korea, and Taiwan, and the 370,000 acres (1,500 km²) of the Catholic Church's landownings in Vietnam were exempted. The political, social, and economic influences of the land reform was minimal.[95] From 1957 to 1963, only 50 percent of expropriated land was redistributed, and only 100,000 out of approximately one million tenant farmers in South Vietnam benefited from the reform.[96]

Resettlement According to Miller, Diệm, who described tenant farmers as a "real proletariat" and pursued the goal of "middle peasantization", was not a beholden to large landowners, instead of vigorously implementing Land Reform, Diệm had his own vision in Vietnamese rural development based on resettlement, which focused on redistribution of people (rather than land), could reduce overpopulation and lead to many benefits in socio-economic transformation as well as military affairs and security, especially anti-communist infiltration. Moreover, Diệm was ambitious to envision Resettlement as a tactic to practice the government's ideological goals. The differences between the US and Diệm over nation building in countryside shaped the clashes in their alliance.[97]

The Cái Sắn resettlement project: In late 1955, with the help of US material support and expertise, Diệm's government implemented the project Cái Sắn in An Giang province, which aimed to resettle one hundred thousand northern refugees.[98]

Land Development program (Khu dinh điền): In early 1957, Diệm started a new program called the Land Development to relocate poor inhabitants, demobilized soldiers, and minority ethnic groups in central and southern Vietnam into abandoned or unused land in Mekong Delta and Central Highlands, and cultivating technological and scientific achievements to transform South Vietnam and ensure security and prevent communist infiltration. Diệm believed that the program would help improve civilians' lives, teach them the values of being self-reliant and hard working. At the end of 1963, the program had built more than two hundred settlements for a quarter of a million people. Nevertheless, the lacks of conditions in these areas along with the corruption and mercilessness of local officials failed the program.[98]

Agroville program (khu trù mật): During late 1959 and early 1960, motivated by the idea of population reunification, Diệm introduced the Agroville Program, which he intended to physically relocate residents who lived in remote and isolated regions in Mekong delta into new settlements in "dense and prosperous areas" – proposing to offer them urban modernity and amenities without leaving their farms,[98] and to keep them far away from the communists. Nonetheless, by late 1960, Diệm had to admit that the program's objective failed since the residents were not happy with the program and the communists infiltrated it, and he had to discard it.[98]

According to Miller, the disagreement between the US and Diệm over agrarian reform made their alliance "move steadily from bad to worse".[98] Miller argues that Diệm expressed "genuine desire to end the exploitation and misery that afflicted millions of South Vietnamese rural residents", and wished to support poor peasantry by gradual modernisation and moderate redistribution of land. Diệm's ideal was rendering the Vietnamese countryside dominated by freeholding farmers with roughly equal position of wealth. Diệm wanted to acquire and distribute the land of rich landowners, but also wished to protect the property of middle-class ones.[99] One of the main concerns of Diệm was overpopulation, aggravated by the mass migration of refugees from the North, something that Diệm wished to alleviate by resettlement. Diệm considered resettlement an important part of his economic nationalism, arguing that utilising Vietnamese land would increase the production of grains and rubber and allow South Vietnam to enter international trade. Ideologically, Diệm considered this policy a key to his "Personalist revolution" – the resettled villages would be "neither communist-style collectives nor incubators of rugged individualism", but they would rather conform to his ideal of communitarianism. Rendering landless peasants freeholders was seen as a step towards reforming the Vietnamese society as a whole.[100] In late 1955, a Cai San Project was launched that aimed to settle northern refugees in rural areas previously occupied by Hòa Hảo partisans. This project created an intense social conflict between the settlers and Cai San natives, and Diệm offered a concession to the local landowners by decreeing that refugees must sign rental contracts with them. This sparked refugee demonstrations that only started to fade away when Diệm ordered that refugees have the right to buy out the land they worked at.[101] While initially considered a failure, especially due to the fact that the resettlement sparked anti-government sentiment and created social conflicts, Miller notes that Cai San became fairly prosperous by 1960, and the settlement did gradually evolve into a pro-government stronghold, thus succeeding in its aim at counter-insurgency. Many of the counter-insurgency programs progressed too quickly however, and ended up destabilising the regime.[102]

During his presidency, Diệm strongly focused on his central concern: internal security to protect his regime as well as maintain order and social change: staunch anti-subversion and anti-rebellion policies. After the Bình Xuyên was defeated and the Hòa Hảo, Cao Đài were subdued, Diệm concentrated on his most serious threat: the communists. Diệm's main measures for internal security were threats, punishment and intimidation.[103] His regime countered North Vietnamese and communist subversion (including the assassination of over 450 South Vietnamese officials in 1956) by detaining tens of thousands of suspected communists in "political re-education centers". The North Vietnamese government claimed that over 65,000 individuals were imprisoned and 2,148 killed in the process by November 1957.[104] According to historian Gabriel Kolko, from 1955 to by the end of 1958, 40,000 political prisoners had been jailed and 12,000 were executed.[105]

By the end of 1959, Diệm was able to entirely control each family and the communists had to suffer their "darkest period" in their history. Membership declined by two thirds and they had almost no power in the countryside of South Vietnam.[106] Diệm's repression extended beyond communists to anti-communist dissidents and anti-corruption whistleblowers. In 1956, after the "Anti-Communist Denunciation Campaign", Diệm issued Ordinance No. 6, which placed anyone who was considered a threat to the state and public order in jail or house arrest.[107]

Nevertheless, Diệm's hard policies led to fear and resentment in many quarters in South Vietnam and negatively affected his relations with the US in terms of counter-insurgent methods.[103] On 22 February 1957, when Diệm delivered a speech at an agricultural fair in Buôn Ma Thuột, a communist named Hà Minh Tri attempted to assassinate the president. He approached Diệm and fired a pistol from close range, but missed, hitting the Secretary for Agrarian Reform's left arm. The weapon then jammed and security overpowered Tri before he was able to fire another shot. Diệm was unmoved by the incident.[108] The assassination attempt was the desperate response of the communists to Diệm's relentless anti-communist policies.[108]

As opposition to Diệm's rule in South Vietnam grew, a low-level insurgency began to take shape there in 1957. Finally, in January 1959, under pressure from southern Viet Cong cadres who were being successfully targeted by Diệm's secret police, Hanoi's Central Committee issued a secret resolution authorizing the use of armed insurgency in the South with supplies and troops from the North. On 20 December 1960, under instructions from Hanoi, southern communists established the Viet Cong (NLF) in order to overthrow the government of the south. On 11 November 1960, a failed coup attempt against President Ngô Đình Diệm of South Vietnam was led by Lieutenant Colonel Vương Văn Đông and Colonel Nguyễn Chánh Thi of the Airborne Division of the ARVN (ARVN).[109] There was a further attempt to assassinate Diệm and his family in February 1962 when two air force officers – acting in unison – bombarded the Presidential Palace.[110][111][112]

South Vietnamese "Strategic Hamlet"

In 1962, the cornerstone of Diệm's counterinsurgency effort – the Strategic Hamlet Program (Vietnamese: Ấp Chiến lược), "the last and most ambitious of Diem's government's nation building schemes", was implemented, calling for the consolidation of 14,000 villages of South Vietnam into 11,000 secure hamlets, each with its own houses, schools, wells, and watchtowers supported by South Vietnamese government. The hamlets were intended to isolate the National Liberation Front (NLF) from the villages, their source for recruiting soldiers, supplies, and information, and to transform the countryside. In the end, because of many shortcomings, the Strategic Hamlet Program was not as successful as had been expected and was cancelled after the assassination of Diệm. However, according to Miller, the program created a remarkable turnabout in Diệm's regime in their war against communism.[113] Frederick Nolting reported that Diệm named reestablishing control and security as his number one priority regarding the countryside. While appearing receptive to building an "infrastructure of democracy" in the rural areas, Diệm emphasised that it would have to wait until the conclusion of the war.[113]

By most estimates, Buddhism was followed by 70–90% of the population,[114][115][116][117][118][119][120] though some estimates place it lower, and Buddhism was followed alongside other traditions such as Vietnamese folk religion and Taoism.[121]

Diem was widely regarded by historians as having pursued pro-Catholic policies that antagonized many Buddhists. Specifically, the government was regarded as being biased towards Catholics in public service and military promotions, as well as the allocation of land, business favors, and tax concessions.[122] Diệm allegedly once told a high-ranking officer, forgetting that he was a Buddhist, "Put your Catholic officers in sensitive places. They can be trusted."[121] Many officers in the Army of the Republic of Vietnam converted to Catholicism in the belief that their military prospects depended on it.[123] The distribution of weapons to village self-defense militias intended to repel Việt Cộng guerrillas saw weapons only given to Catholics. Some Buddhist villages converted en masse to Catholicism in order to receive aid or to avoid being forcibly resettled by Diệm's regime,[124] with Buddhists in the army being denied promotion if they refused to convert to Catholicism.[125] Some Catholic priests ran their own private armies,[126] and in some areas forced conversions, looting, shelling, and demolition of pagodas occurred.[127] Słowiak argues that Diem's favoritism towards Catholics was not a sign of corruption and nepotism, but that it was necessary for Diem to favor people loyal towards him, given the precarious internal situation of Vietnam.[121]

The Catholic Church was the largest landowner in the country, and the "private" status imposed on Buddhism by the French required official permission to conduct public Buddhist activities and was never repealed by Diệm.[128] Catholics were also de facto exempt from the corvée labor that the government obliged all citizens to perform; US aid was disproportionately distributed to Catholic-majority villages.[129] The land owned by the Catholic Church was exempt from land reform.[130] Under Diệm, the Catholic Church enjoyed special exemptions in property acquisition, and in 1959, Diệm dedicated his country to the Virgin Mary.[129] The white and gold Vatican flag was regularly flown at all major public events in South Vietnam.[131] The newly constructed Hue and Dalat universities were placed under Catholic authority to foster a Catholic-skewed academic environment.[132] Nonetheless, Diệm had contributed to Buddhist communities in South Vietnam by giving them permission to carry out activities that were banned by the French and supported money for Buddhist schools, ceremonies, and building more pagodas. Among the eighteen members of Diệm's cabinet, there were five Catholics, five Confucians, and eight Buddhists, including a vice-president and a foreign minister. Only three of the top nineteen military officials were Catholics.[133]

The regime's relations with the United States worsened during 1963, as discontent among South Vietnam's Buddhist majority was simultaneously heightened. In May, in the heavily Buddhist central city of Huế – the seat of Diệm's elder brother as the local Catholic archbishop – the Buddhist majority was prohibited from displaying Buddhist flags during Vesak celebrations commemorating the birth of Gautama Buddha when the government cited a regulation prohibiting the display of non-government flags.[134] A few days earlier, however, white and yellow Catholic papal flags flew at the 25th anniversary commemoration of Ngô Đình Thục's elevation to the rank of bishop.[135] According to Miller, Diệm then proclaimed the flag embargo because he was annoyed with the commemoration for Thục.[136] However, the ban on religious flags led to a protest led by Thích Trí Quang against the government, which was suppressed by Diệm's forces, and unarmed civilians were killed in the clash. Diệm and his supporters blamed the Việt Cộng for the deaths and claimed the protesters were responsible for the violence.[137] Although the provincial chief expressed sorrow for the killings and offered to compensate the victims' families, they resolutely denied that government forces were responsible for the killings and blamed the Viet Cong. According to Diệm, it was the communists who threw a grenade into the crowd.[138]

The Buddhists pushed for a five-point agreement: freedom to fly religious flags, an end to arbitrary arrests, compensation for the Huế victims, punishment for the officials responsible, and religious equality. Diệm then banned demonstrations and ordered his forces to arrest those who engaged in civil disobedience. On 3 June 1963, protesters attempted to march towards the Từ Đàm pagoda. Six waves of ARVN tear gas and attack dogs failed to disperse the crowds. Finally, brownish-red liquid chemicals were doused on praying protesters, resulting in 67 being hospitalized for chemical injuries. A curfew was subsequently enacted.[139]

Buddhist monk, Thích Quảng Đức, set himself on fire in the middle of a busy Saigon intersection in protest of Diệm's policies

The turning point came in June when a Buddhist monk, Thích Quảng Đức, set himself on fire in the middle of a busy Saigon intersection in protest of Diệm's policies; photos of this event were disseminated around the world, and for many people these pictures came to represent the failure of Diệm's government.[140] A number of other monks publicly self-immolated, and the US grew increasingly frustrated with the unpopular leader's public image in both Vietnam and the United States. Diệm used his conventional anti-communist argument, identifying the dissenters as communists. As demonstrations against his government continued throughout the summer, the special forces loyal to Diệm's brother, Nhu, conducted an August raid of the Xá Lợi pagoda in Saigon. Pagodas were vandalized, monks beaten, and the cremated remains of Quảng Đức, which included his heart, a religious relic, were confiscated. Simultaneous raids were carried out across the country, with the Từ Đàm pagoda in Huế looted, the statue of Gautama Buddha demolished, and the body of a deceased monk confiscated.[141] When the populace came to the defense of the monks, the resulting clashes saw 30 civilians killed and 200 wounded. In all 1,400 monks were arrested, and some thirty were injured across the country. The United States indicated its disapproval of Diệm's administration when ambassador Henry Cabot Lodge Jr. visited the pagoda. No further mass Buddhist protests occurred during the remainder of Diệm's rule.[142]

Madame Nhu Trần Lệ Xuân, Nhu's wife, inflamed the situation by mockingly applauding the suicides, stating, "If the Buddhists want to have another barbecue, I will be glad to supply the gasoline."[143] The pagoda raids stoked widespread public disquiet in Saigon. Students at Saigon University boycotted classes and rioted, which led to arrests, imprisonments, and the closure of the university; this was repeated at Huế University. When high school students demonstrated, Diệm arrested them as well; over 1,000 students from Saigon's leading high school, most of them children of Saigon civil servants, were sent to re-education camps, including, reportedly, children as young as five, on charges of anti-government graffiti. Diệm's foreign minister Vũ Văn Mẫu resigned, shaving his head like a Buddhist monk in protest.[144] When he attempted to leave the country on a religious pilgrimage to India, he was detained and kept under house arrest.[145]

At the same time that the Buddhist crisis was taking place, a French diplomatic initiative to end the war had been launched. The initiative was known to historians as the "Maneli affair", after Mieczysław Maneli, the Polish Commissioner to the International Control Commission who served as an intermediary between the two Vietnams. In 1963, North Vietnam was suffering its worst drought in a generation. Maneli conveyed messages between Hanoi and Saigon negotiating a declaration of a ceasefire in exchange for South Vietnamese rice being traded for North Vietnamese coal.[146] On 2 September 1963, Maneli met with Nhu at his office in the Gia Long Palace, a meeting that Nhu leaked to the American columnist Joseph Alsop, who revealed it to the world in his "A Matter of Fact" column in the Washington Post.[147] Nhu's purpose in leaking the meeting was to blackmail the United States with the message that if Kennedy continued to criticize Diem's handling of the Buddhist crisis, Diem would reach an understanding with the Communists. The Kennedy administration reacted with fury at what Alsop had revealed.[148] In a message to Secretary of State Dean Rusk, Roger Hilsman urged that a coup against Diem be encouraged to take place promptly, saying that the mere possibility that Diem might make a deal with the Communists meant that he had to go.[148]

There have been many interpretations of the Buddhist crisis and the immolation of Thích Quảng Đức in 1963. Relating the events to the larger context of Vietnamese Buddhism in the 20th century and looking at the interactions between Diệm and Buddhist groups, the Buddhist protests during Diệm's regime were not only the struggles against discrimination in religious practices and religious freedom, but also the resistance of Vietnamese Buddhism to Diệm's nation-building policies centered by a personalist revolution that Buddhists considered a threat to the revival of Vietnamese Buddhist power.[149] Until the end of his life, Diệm, along with his brother Nhu still believed that their nation-building was successful and they could resolve the Buddhist crisis in their own way, like what they had done with the Hinh crisis in 1954 and the struggle with the Bình Xuyên in 1955.[150]

Jerema Słowiak of Jagiellonian University notes that the American media coverage skewed the true background of the conflict, spreading the "narrative of evil dictator Diệm oppressing good, peaceful Buddhists". Because of this, Diệm was considered a brutal and corrupt dictator in the United States at the time of his assassination.[121] However, Diệm enjoyed relatively good relations with the Buddhists until 1963, and sponsored numerous Buddhist temples, especially Xá Lợi Pagoda in 1956. Vietnamese Buddhists had a nationalist vision for Vietnam of their own, and were political enemies of Diệm, engaged in "a clash of two competing visions of Vietnam".[121] The Buddhist challenge to Diệm was politically motivated and constituted struggle for power rather than a religious conflict – the Buddhists protested mainly against the Ngo family and rejected Diệm's concessions, as their explicit goal was removal of Diệm.[121] Thích Trí Quang, the leader of the Buddhist movement, insisted that the agitation must not stop until the South Vietnamese government is overthrown, and stated his intention to "call for suicide volunteers" if necessary. Edward Miller also argues that the primary cause of the protests was the opposition to Diệm and his agenda rather than the discriminatory policies, as the Buddhist movements of Vietnam had their own political goals that starkly contrasted with Diệm's.[149] Diệm reacted to the Buddhist resistance the same way he reacted to the Sect Crisis of 1955, and Xá Lợi Pagoda raids successfully broke the protesters' movement. The military supported Diệm, and army leaders helped plan the raids and advocated for a forceful response to the protests, and only American disapproval drove military cliques to reconsider their support for Diệm.[121]

The foreign policy of the Republic of Vietnam (RVN), according to Fishel, "to a very considerable extent", was the policy of Ngo Dinh Diem himself during this period.[151] He was the decisive factor in formulating foreign policies of the RVN, besides the roles of his adviser – Ngô Đình Nhu and his foreign ministers: Trần Văn Độ (1954–1955), Vũ Văn Mẫu (1955–1963) and Phạm Đăng Lâm (1963) who played subordinate roles in his regime. Nevertheless, since Diệm had to pay much attention to domestic issues in the context of the Vietnam War, foreign policy did not receive appropriate attention from him. Diệm paid more attention to countries that affected Vietnam directly and he seemed to personalize and emotionalize relations with other nations.[152] The issues Diệm paid more attention in foreign affairs were: the Geneva Accords, the withdrawal of the French, international recognition, the cultivation of the legitimacy of the RVN and the relations with the United States, Laos (good official relations) and Cambodia (complicated relations, especially due to border disputes and minority ethnicities), and especially North Vietnam.[152] Besides, the RVN also focused on diplomatic relations with other Asian countries to secure its international recognition.[153]

Diệm's attitude toward India was not harmonious due to India's non-alignment policy, which Diệm assumed favored communism. It was not until in 1962, when India voted for a report criticizing the communists for supporting the invasion of South Vietnam, that Diệm eventually reviewed his opinions toward India.[154] For Japan, Diệm's regime established diplomatic relations for the recognition of war reparations, which led to a reparation agreement in 1959 with the amount of US$49 million (equivalent to US$514 million in 2023). Diệm also established friendly relations with non-communist states, especially South Korea, Taiwan, the Philippines, Thailand, Laos and the Federation of Malaya, where Diệm's regime shared the common recognition of communist threats.[155]

Regarding the relations with communist North Vietnam, Diệm maintained total hostility and never made a serious effort to establish any relations with it.[156] In relations with France, as an anti-colonialism nationalist, Diệm did not believe in France and France was always a negative factor in his foreign policy. He also never "looked up on France as a counterweight to American influence".[157]

Concerning relations with the US, although Diệm admitted the importance of the US-RVN alliance, he perceived that the US's assistance to the RVN was primarily serving its own national interest, rather than the RVN's national interest.[158] Taylor adds that Diệm's distrust of the US grew because of its Laotian policy, which gave North Vietnam access to South Vietnam's border through southern Laos. Diệm also feared the escalation of American military personnel in South Vietnam, which threatened his nationalist credentials and the independence of his government.[159] In early 1963, the Ngô brothers even revised their alliance with the US.[160] Moreover, they also disagreed with the US on how to best react to the threat from North Vietnam. While Diệm believed that before opening the political system for the participation of other political camps, military, and security matters should be taken into account; the US wanted otherwise and was critical of Diệm's clientelistic government, where political power based on his family members and trusted associates. The Buddhist crisis in South Vietnam decreased American confidence in Diệm, and eventually led to the coup d'état sanctioned by the US.[159] Ultimately, nation-building politics "shaped the evolution and collapse of the US-Diem alliance". The different visions in the meanings of concepts – democracy, community, security, and social change – were substantial, and were a key cause of the strains throughout their alliance.[160]
