"It is very easy to receive a pat on the shoulder from the international community, to bow one's head," Netanyahu said yesterday at a candle-lighting ceremony in Rome's main synagogue which he visited with Letta.
"I would like to dispel any illusions. Iran aspires to attain an atomic bomb. It would thus threaten not only Israel but also Italy, Europe and the entire world," he was quoted as saying on his website.
Netanyahu later today will be received for the first time at an audience by Pope Francis, who is expected to travel to the Middle East next year.
Israeli sources say the visit could take place before Israeli President Shimon Peres ends his term in July.
Although no date has been made official, sources on both sides say it is likely to take place on May 25-26.
Netanyahu and Francis are also expected to discuss negotiations between Israel and the Palestinians, which resumed in July after a three-year hiatus but have faltered due to Israeli plans for new settlement building.
