Did any Arabs save Jews during the Holocaust? Seeking a response to the plague of Holocaust denial in the Arab world, Robert Satloff, head of a respected Washington policy center, set off in the wake of 9/11 on what would become an eight-year journey to find an Arab hero whose story would change the way Arabs view Jews, themselves and their own history. Along the way, Satloff found not only the Arab heroes whom he sought, but a vast, lost history of what happened to the half-million Jews of the Arab lands of North Africa under Nazi, Vichy and Fascist rule. Robert MacNeil narrates.
