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."
