Haïti Observateur in 1971, which became influential and widely circulated among the Haitian diaspora. Joseph subsequently worked as a reporter at the
Wall Street Journal and a columnist at the
New York Sun. Joseph turned his attention to the ongoing authoritative Duvalier regime in Haiti and built a network of informants inside the presidential palace of Port-au-Prince. He then would broadcast his intel from Brooklyn and in shortwaves in Haiti that became known as
Radio Vonvon, in which anti-communist associates from California and
Ronald Reagan played a role in its formation. In an attempt to uncover the leaks inside of the palace, François Duvalier murdered 19 members of its guard and sent an assassin to New York to dispose of Joseph. However, during a flight to New York, one of Joseph's sources was on the same plane and managed to tip him off. Expecting the assassin's arrival, he made a phone call to the would-be assassin, proposed a meeting and ended up having coffee together subsequently avoiding assassination.

son finally collapsed in 1986. In 1990, Joseph was appointed the Haitian Government's
chargé d’affaires in Washington, D.C., and the representative of the Haitian Government to the

Haïti Observateur where he remained until 2004, when he was again appointed Chargé d'Affaires in Washington, D.C. In 2005 acting president
Boniface Alexandre chose Joseph to be Haiti's ambassador to the United States. In the aftermath of the catastrophic
