Iran hosts anti holocaust delegation

Iran is hosting a conference in Tehran for those people that don't believe the holocaust ever happened or that it was extremely exagerated.
President Ahmadinejad told people attending the conference that Israels days are numbered. "Thanks to people's wishes and God's will, the trend for the existence of the Zionist regime is downwards and this is what God has promised and what all nations want," he said. "Just as the Soviet Union was wiped out and today does not exist, so will the Zionist regime soon be wiped out," he added.
His comments were applauded by those attending the conference which included ultra orthodox jews, and European, and American writer who believe that the holocaust never happened or that it was exagerated.
The thing that boggles my mind is that any Jew would attend such a conference, no matter how orthodox they may be, why would they want the state of Israel destroyed ?

Israeli P.M. admits having nuclear weapons

In an interview with a German television station the Israeli Prime Minister was asked about Iran's calls for the destruction of Israel.
The Prime Minister's response was this, "Iran openly, explicitly and publicly threatens to wipe Israel off the map," Olmert said. "Can you say that this is the same level, when you are aspiring to have nuclear weapons, as America, France, Israel, Russia?"
In addition to this comment, the U.S.A.'s new defence secretary identified Israel as a nuclear power only days ago.
Is this the end to Israel's policy of ambiguity regarding its supposed nuclear weapons program ?
