But it may be the first that also dreams of wiping the Jews out of Jewish history. Arab efforts to delegitimise Jews are as old as the Qur'an.
Arab regimes take special pains to indoctrinate that hatred into children.
But now there is a new twist to the anti-Jewish demonology. Western Jerusalem, with its half-million Jewish residents, disappears. A few weeks ago, the Palestinian Authority's television channel aired a program asserting that the tales of the Old Testament took place in what is today Yemen, not in Israel. Another PA-TV show argued that Palestinian Arabs are the true descendants of the biblical Israelites. What makes the wall significant, the PA says, is that Mohammed tied up his magical steed there before ascending to heaven.
