She is one of two surviving children of Dany Chamoun (1934–1990), the former leader of the National Liberal Party and commander of the Tigers militia, which played a significant role in the Lebanese Civil War of 1975 to 1990, and the granddaughter of former President Camille Chamoun.
Through the Dany Chamoun Foundation, Chamoun has sought to perpetuate the legacy of her father, who was assassinated together with his second wife and two young sons by unknowns after the Syrian Forces occupied the Eastern Area of Beirut (Christian Region) and the crime was allegedly attributed to the Lebanese Forces militia who in turn accuse the occupation secret services, on October 21,1990. Her autobiography, Au Nom du Pere, centered on her relationship with her father and his life and work. In it, she recounts the harrowing experience in which she and her mother were kidnapped in 1980 during a surprise attack on the National Liberal Party headquarters by Phalangist militiamen under the command of Bachir Gemayel, her father's former ally.
Chamoun was an outspoken critic of the former Syria occupation of Lebanon. She has described her country's independence as a "myth". "To what extent does the establishment believe that the population is so blind that it cannot see that the nation is far from independent?" she asked rhetorically before the Independence Day celebrations in 1990. "Like the myth of the emperor with no clothes, it is a charade that only the sycophants see and celebrate", she added.
Chamoun is known for her moderate political views. She favors the building of a modern democracy, and has spoken out against what she sees as the feudal political system in which clan loyalties often play a more significant role than ideology in politics. She is critical of her uncle, Dory Chamoun, head of the National Liberal Party, for his alliance with Samir Geagea, the man convicted of killing her family. Publicly, however, she has defended her uncle, and has refused to enter into discussions with those critical of him.
Chamoun has vowed to continue to remind people of the truth behind the assassination of her slain father which she writes about in her books Le Sang De la Paix published by Lattes in France and ثمن السلم published by Antoine in Lebanon.
