ISRAELI Minister Benjamin Netanyahu's UN speech about Iranian nuclear advances has dampened speculation he could order a war this year.

Analysing the address, in which Mr Netanyahu literally drew a "red line" on a cartoon bomb to show how close Iran was to building nuclear weaponry, commentators saw his deadline for any military action falling in early or mid-2013, well after US elections in November and a possible snap Israeli poll.

"The 'decisive year' of 2012 will pass without decisiveness," wrote Ofer Shelah of Maariv newspaper yesterday.

Mr Netanyahu implied Israel would attack Iran's uranium enrichment facilities if they were allowed to process potential weapons-grade material beyond his red line.

Maariv and another mass-circulation Israeli daily, Yedioth Ahronoth, said spring 2013 now looked like Mr Netanyahu's target date, given his prediction that by then Iran may have amassed enough 20%-enriched uranium for a first bomb, if purified further.

But the front pages of the liberal Haaretz and pro-Government Israel Hayom newspapers cited mid-2013, Mr Netanyahu's outside estimate for when the Iranians would be ready to embark on the last stage of building such a weapon.

Iran, which denies it is seeking nuclear arms, said Mr Netanyahu's speech made "baseless and absurd allegations" and that the Islamic Republic "reserves its full right to retaliate with full force against any attack". Israel is widely assumed to have the Middle East's only atomic arsenal.

Israeli diplomats were reluctant to elaborate on Mr Netanyahu's speech, saying its main aim was to illustrate the threat from Tehran.

Mr Netanyahu's increasingly hawkish words on Iran in recent weeks and months strained relations with US President Barack Obama, who has resisted the calls to set Tehran an ultimatum.
