"In his book Israel and the Movement for the Liberation of South Sudan, published in 2003 by the Moshe Dayan Center for Middle Eastern and African Studies, the retired Mossad Brig Gen Moshe Fergie wrote that Israel's support to South Sudan rebels has gone through five phases: 1950s, through humanitarian aid; early 1960s, by training members of the "Popular Army" in Ethiopian outposts; mid-1960s-1970s, by routing weapons to the South; late 1970s-1980s, by backing southern leader John Garang; late 1990s, by providing the South with heavy weaponry via Kenya and Ethiopia."
