Yad Vashem Chairman Avner Shalev told Army Radio that anti-Zionist graffiti was painted at 10 spots across the memorial compound, including a slogan that read, "Hitler, thank you for the Holocaust," and, "Jews, wake up, the evil Zionist regime doesn't protect us, it jeopardizes us."
"It's a very grave crossing of a red line," Shalev said. Asked if he suspected radical ultra-Orthodox Jews were to blame, he said the slogans were written in excellent Hebrew handwriting and one was signed "world ultra-Orthodox Jewry."
Many Ultra-Orthodox Jews are anti-Zionist because they think a Jewish state should not be established before the coming of the Messiah. Some subscribe to the conspiracy theory that Israel's founders colluded with Hitler to achieve their goal of establishing a state for Jews.
