As Supreme Commander of the NLP's military wing, the Tigers, he also played a major role in the early years of the Lebanese Civil War.

[5] In 1988, he became President of the revived Lebanese Front—a coalition of nationalist and mainly Christian parties and politicians that his father had helped to found.

He strongly opposed the Taif Agreement, which not only gave a greater share of power to the Muslim community than they had enjoyed previously, but more seriously, in Chamoun's opinion, formalized what he saw as the master-servant relationship between Syria and Lebanon, and refused to recognize the new government of the President Elias Hrawi, who was elected under the Taif Agreement.

Dany Chamoun and Bachir Gemayel claimed that they didn't destroy the entire camp out of concern for the lives of civilians.

[3][11] On 24 June 1995, the Lebanese Tribunal found Christian rival Samir Geagea guilty of the murder of Dany Chamoun and his family.

[12] The verdict was rejected by a part of the Lebanese public opinion and by Dany's brother, Dory Chamoun, who declared that the Syrian occupation army was responsible for the massacre.
