Xá Lợi Pagoda
In 1955, Nhu's supporters helped intimidate the public and rig the 1955 State of Vietnam referendum that ensconced his elder brother, Diệm, in power. Nhu used the Cần Lao, which he organised into cells, to infiltrate every part of society to root out opposition to the Ngô family. In 1959, he organized a failed assassination attempt via mail bomb on Prince Sihanouk, the prime minister of neighbouring Cambodia, with whom relations had become strained. Nhu publicly extolled his own intellectual abilities. He was known for making such public statements as promising to demolish the Xá Lợi Pagoda and vowing to kill his estranged father-in-law, Trần Văn Chương, who was the regime's ambassador to the United States, after the elder man condemned the Ngô family's behavior and disowned his daughter, Nhu's wife, Madame Nhu.
