Jerusalem ? Israeli Prime Minister Ehud Olmert on Friday compared Iran’s nuclear ambitions and threats against Israel to the policies of Nazi Germany and criticized world leaders who maintain relations with Iran’s president.

Olmert’s speech during a ceremony at Israel’s national Holocaust memorial came after a new report that Iran has doubled its capability to enrich uranium.

Israel has identified Iran as the greatest threat to the Jewish state.

Israel’s concerns have heightened since the election of Iran’s hard-line president, Mahmoud Ahmadinejad, who frequently calls for the destruction of Israel and has questioned whether the Nazi genocide of 6 million Jews took place.

Olmert said Iran’s nuclear program is designed to secure “conventional weapons with delivery systems” to annihilate Israel.
