OCCUPIED JERUSALEM: Israeli Prime Minister Benjamin Netanyahu has denied accusations he is interfering in the U.S. presidential vote by pushing President Barack Obama to take a tougher stand on Iran's nuclear program.

In newspaper interviews published Friday ahead of the Jewish new year, Netanyahu dismissed accusations that he is trying to paint Obama as weak on Iran in order to boost support for Republican candidate Mitt Romney.

"That's nonsense," he told the Israel Hayom daily, which is considered close to him.

"The issue that guides me is not the elections in the United States but the centrifuges in Iran. What can we do if the centrifuges in Iran pay no attention to the political timetable in the United States?

"It has nothing to do with the American elections," he added, in an interview with the Jerusalem Post newspaper.

"If the centrifuges stop miraculously, if they stop preparing enriched uranium to make atomic bombs, then I suppose I wouldn't have to speak out.

"For me this is a policy issue, a security issue, and not a political issue," he said.

The comments are excerpts from longer interviews to be published in full Sunday, the eve of the Jewish new year, or Rosh Hashana.

Opposition leader Shaul Mofaz on Wednesday said that Netanyahu's pursuit of a very public dispute with Obama over Iran was an attempt to sway voters against the U.S. leader in the November election.

"Israeli meddling in internal U.S. affairs and turning the U.S. administration from an ally to 'an enemy' has caused us severe damage," Mofaz charged, at a session of the Israeli parliament, known as the Knesset.

"Please explain to us: who is Israel's greatest enemy -- the U.S. or Iran? Who do you fear more -- (Iranian President Mahmoud) Ahmadinejad or Obama? Which regime is more important to overthrow -- the one in Washington, or in Tehran?" he asked.

Similar criticism has been expressed by Israeli and U.S. media over Netanyahu's repeated demands that Obama set unambiguous 'red lines' with regard to Iran's nuclear program, which Israel and much of the West believes masks a weapons drive.

Israel, the Middle East's sole, if undeclared, nuclear power, has said a nuclear-armed Iran would pose an existential threat to the Jewish state and has threatened unilateral military action against Tehran.

But Washington backs continued diplomatic pressure and says it is not the time for a strike.
