Sean Stone, the son of acclaimed film director Oliver Stone, has defended Iranian President Mahmoud Ahmadinejad as "really misunderstood." In an interview with Bill O'Reilly on Fox News, Stone attempted to explain controversial comments that the Iranian president has made in the past about Israel and the Holocaust. The director's son explained that when Ahmadinejad "says Israel should be dissolved," he is "talking about the West Bank. On Holocaust denial, Stone said that the Iranian president's point has always been that if it happened in Europe, "Why should it influence Israeli policy in regards to the Palestinians?""It's simplistic to say that he's a fanatic," Stone said of the Iranian president, while insisting, "There's no room for Holocaust denial, of course." Stone went on to tell O'Reilly that he had told the Iranians to "stop with this down with America nonsense," and claimed that they had understood his point of view.Stone also told O'Reilly that he had spoken with Jews in the Iranian city of Isfahan, where he converted to Islam earlier this month.When questioned as to whether he is "okay with Iran having a nuclear weapon," Stone told O'Reilly, "I am, because it's a republic. There are factions."
