Ben Yosef was the Israeli Foreign Minister.
He came to the United States to present Leo McGarry with the Medal of David. He questioned Leo about the disappearance of Abdul ibn Shareef. Leo told him that Qumar was about to announce Israel was behind Shareef's disappearance and presumed death, and he asked Israel to put off bombing two Qumari training bases so that Admiral Fitzwallace could pressure the Qumari not to make the accusation yet. Yosef's airplane was shot down on his return to Israel, and he was killed.[1]
Leo later cited Yosef's death as a reason he was no longer willing to tolerate Qumar.[2]
