*a founding director of the pro-Israel think tank the Washington Institute for Near East Policy (WINEP)
*a director of the pro-Israel Saban Center for Middle East Policy
*a two-time US ambassador to Israel (1995-97; 2000-01)
*a key Clinton adviser (along with Dennis Ross) at the 2000 Camp David summit at which "Palestinian negotiators complained that they were 'negotiating with two Israeli teams - one displaying an Israeli flag, and one an American flag'."
