From the late 19th century, Arab populations grew and prospered where Jews settled (Tel Aviv, Hebron, Jerusalem) and remained stagnant and poor where they didn’t (Gaza, Nablus, Nazareth). Many Arabs found the presence of Jews a great advantage. Thus the Palestinian diaspora is among the best-educated and most competent in the Arab world—and under Israeli rule (the notorious “occupation”) the West Bank was one of the 10 fastest-growing economies in the world in the 1980s.

Other Palestinians, however, found Jewish economic leadership an unbearable blow to their pride. Said one to the British Peel Commission in 1936: “You say we are better off: you say my house has been enriched by the strangers who have entered it. But it is my house, and I did not invite the strangers in, or ask them to enrich it, and I do not care how poor it is if I am only master of it.”

Sooner rule in hell than share in heaven. These actors have dominated Palestinian political culture, and terrorized Israeli and Palestinian alike, for generations.

In calling Mr. Romney’s remarks “racist” and blaming Palestinian economic difficulties on Israel’s “occupation,” Mr. Erekat illustrated one of David Landes’s major points: Blaming others for one’s own failures prolongs failure. Even though his own government daily chooses a culture of death, not life, Mr. Erekat wants to blame Israel for Palestine’s woes; no admission here that he and his colleagues might have some role in the suffering of their own people.
