Mel Gibson's appearance in Oklahoma Monday to attend a sneak screening of his movie Apocalypto has prompted new questions about the sincerity of his promise to mend fences with the Jewish community, ABC News reported Wednesday. Rabbi Marvin Hier of the Simon Wiesenthal Center in Los Angeles told ABC News entertainment producer Buck Wolf, "He said he'd reach out to the Jewish community, and he simply hasn't done that yet." Abraham Foxman, National Director of the Anti-Defamation League, added: "It's amazing that he waited for weeks after that incident to make a public appearance, and when he did, it wasn't to make good on his apology, but rather to sell his film." Foxman took note of Gibson's remarks Monday condemning the war in Iraq, comparing them with his drunken comments when he was arrested that "the Jews are responsible for all the wars in the world." Said Foxman: "If Jews are responsible for all the world's wars, then by that logic, they are responsible for the war in Iraq. ... Gibson has to put matters like that to rest. Until he does, it just hangs over him."
