On 8 May 1963, a series of celebrations were held by Buddhist priests all over South Vietnam to honor Buddhist holiday of
Vesak, as 8 May was the 2,527th anniversary of the Buddha's birthday. The Catholic Diệm disapproved of Vesak, and ordered the police to put down the celebrations under a law which forbade religious symbols from being paraded in the streets. A series of clashes occurred all over South Vietnam as the police sought to end the marches. When she heard that Diệm was to sign a statement offering compensation to the families of Buddhist protesters shot dead by the police of his brother
Ngô Đình Cẩn, Nhu was reported to have thrown a bowl of soup at him. On 8 June 1963, Madame Nhu released a statement through the Women's Solidarity Movement accusing the Buddhists of neutralism, effectively accusing them of being
communist collaborators. It then implored "
bonzes of good faith" to stop helping the communists, otherwise Vietnamese Buddhism would be seen as a "small anti-nationalist branch of a dubious international association, exploited and controlled by communism and oriented to the sowing of the disorder of neutralism". She made another attack on the United States, calling on Diệm to "keep vigilance on all others, particularly those inclined to take Viet Nam for [a] satellite of [a] foreign power or organization." Madame Nhu publicly mocked
Thích Quảng Đức, who performed a
self-immolation on 11 June 1963 in a crowded
Saigon street to protest against the shooting of Buddhists by Diệm's regime. She labelled it a "barbecue" and stated, "Let them burn and we shall clap our hands." She further offered to provide more fuel and matches for the Buddhists, noting the "barbecuing" was not "self-sufficient" because "imported gasoline" was used. The monk's suicide followed Ngô Đình Nhu's repression of the Buddhist-inspired protests and was responsible for the regime's continuing instability. According to historian Howard Jones, these comments "all but put the finishing touch on the Diệm regime". Her own father went on radio to condemn her comments. A
Confucian,
Chương said that the regime had alienated "the strongest moral forces", implying that they had lost the
Mandate of Heaven. She responded by calling him a "coward". Her mother said that "There is an old proverb in my country which means 'one should not make oneself or one's family naked before the world'... I was sick... Now, nobody can stop her ... She never listened to our advice." After these comments, the U.S. ambassador,
Frederick Nolting, told Diệm that if he did not denounce his sister-in-law's comment in public, the U.S. would have to stop supporting him, but the president refused to do so, and assailed the monks. In an interview with
David Halberstam, Madame Nhu said that it was "embarrassing to see people [Buddhist leaders] so uncultured claiming to be leaders". The U.S. embassy told Diệm that these comments violated an agreement between the Buddhists and his regime to avoid verbal exchanges, but Diệm refused to keep his family's end of the bargain, saying that his sister-in-law was obliged to expose "extremists" to keep the public informed. In July, the U.S. government rejected a request from her to travel to the United States for a public speaking tour, fearing a public relations disaster. On 3 August, she called the Buddhists "
seditious elements who use the most odious Communist tactics to
subvert the country." This occurred after
special forces loyal to the Ngôs
raided the Xá Lợi Pagoda in Saigon in August. The pagoda was vandalized, monks beaten, and the cremated remains of
Thích Quảng Đức, which included a heart which had not disintegrated, were confiscated. Simultaneous raids were carried out across the country, with the
Từ Đàm Pagoda in
Huế being looted, the statue of
Gautama Buddha demolished, and the body of a deceased monk stolen. When the populace came to the defense of the monks, the resulting clashes saw 30 civilians killed and 200 wounded. Notably, President Diệm sent his sister-in-law a letter asking her not to talk in public about the clashes as her "barbecue" remarks had been a public relations disaster for his regime, both at home and abroad. Through her paramilitary organization, Madame Nhu claimed that the Buddhists were "controlled by communism" and that they were manipulated by the Americans, calling on Diệm to "expel all foreign agitators whether they wear monks' robes or not". A few days after the raids, Madame Nhu described the deadly attacks on the Buddhists as "the happiest day in my life since we crushed the
Bình Xuyên in 1955", and assailed them as "communists". The United States, in a position of some leverage owing to the considerable U.S. aid flowing into South Vietnam, in August 1963 wished to give President Diệm a chance to rid himself of both his brother and Madame Nhu. In a cable drafted by Assistant Secretary of State for Far Eastern Affairs,
Roger Hilsman, to
Ambassador Henry Cabot Lodge, Lodge was instructed to advise Diệm of a call for "the removal of the Nhus from the scene." U.S. President
John F. Kennedy supported the message in
the cable upon its approval by most of his advisors. Her comments further stoked open infighting with her parents, who would eventually disown her and seek refuge in the United States. Her father,
Trần Văn Chương, the ambassador to the United States, resigned in protest, along with all but one of the staffers at the embassy. Chương charged Diệm with having "copied the tactics of totalitarian regimes". His wife, who was South Vietnam's observer at the United Nations, resigned and spoke of mass executions and a reign of terror under Diệm and Nhu. She predicted that if Diệm, Nhu, and Madame Nhu did not leave Vietnam, then they would inevitably be killed. Madame Nhu claimed Buddhist leader
Thích Trí Quang "spoke for many intellectuals who had repeatedly ridiculed her." Following the pagoda raids, Trí Quang was given asylum at the U.S. Embassy after
Ngô Đình Nhu's plans to assassinate him were uncovered. Madame Nhu gave a media interview in which she called on government troops to invade the American embassy and capture Thích Trí Quang and some other monks who were staying there, saying that the government must arrest "all key Buddhists". In a media interview, her husband responded to his parents-in-law by vowing to kill his father-in-law, claiming his wife would participate. He said "I will have his head cut off. I will hang him in the center of a square and let him dangle there. My wife will make the knot on the rope because she is proud of being a Vietnamese and she is a good patriot." ==Visiting the United States==
