Omar Karami
In 2001, as one of the founding members of the Qornet Shehwan Gathering, he strongly expressed his opposition to the policies of the Hariri government and to Syrian hegemony. In 2004, Harb participated, with Nayla Moawad, Omar Karami, Salim Hoss, Hussein Husseini and Albert Mansour, in the creation of a National Face for Reform. In 2004, he declared himself a nominee for the Presidency of Lebanon, however due to a Syrian-engineered constitutional amendment extending the term of President Émile Lahoud, he was unable to run. He then broke his alliance with Omar Karami who he considered to be too pro-Syrian.
