Israeli Prime Minister Ehud Olmert, in a thinly veiled reference to Iran, said Sunday that Israel would "not allow the world" to be indifferent to calls for the Jewish people's destruction.

Olmert spoke after the U.N. General Assembly adopted a resolution condemning the denial of the Holocaust. The resolution did not single out any country, but it clearly was directed at Iran, which provoked widespread anger last month by holding a conference casting doubt on the Nazi genocide of Jews.

The Iranian president, Mahmoud Ahmadinejad, has called the Holocaust a "myth" and has repeatedly preached the destruction of the Jewish state.

"We will not allow the world to once again sink into indifference, heedlessness and silence, thereby giving moral approval to speak in such terms about the existence of the Jewish people," Olmert told members of his Cabinet on Sunday, without mentioning Iran by name.

Israel considers Iran to be its most dangerous enemy and Olmert repeatedly warns of the risk of allowing Tehran to acquire nuclear weapons. Israel has not said straight out that it would launch a military strike to cripple Iran's nuclear program, as it did against an Iraqi nuclear reactor in 1981, but has hinted repeatedly it might do so.

Tehran insists its nuclear program is designed to produce energy, not weapons.

The Iranian envoy to the U.N., Hossein Gharibi, said Friday when the resolution was passed that the Holocaust should be closely examined to determine its scope.

Last week, Israel's Holocaust memorial, Yad Vashem, launched a version of its Web site in Farsi to educate Iran about the Jewish genocide.
