"... Sharon and Jumblatt,... had mutual friends, including the current head of the Mossad, Meir Dagan..."

"...Years passed and in the summer of 1982, defense minister Ariel Sharon met with Bashir Gemayel. The head of the Lebanese Phalange party declared that the end of Lebanese Druze leader Walid Jumblatt was nearing. Sharon and Jumblatt, who hated Syria for murdering his father, had mutual friends, including the current head of the Mossad, Meir Dagan; but Gemayel boasted that the clan that was on the rise in the Druze community, the Yazbeks, were his allies. "Pull your Druze out," Gemayel demanded, and Sharon gave in and promised that the IDF officers of Druze descent would be removed from the areas of confrontation between the Maronites and the Druze."
