The gap between Israeli and American perspectives on Iran appeared to widen on Sunday as Prime Minister Binyamin Netanyahu insisted on a "red line" from Washington, claiming Tehran is "90 per cent" finished developing a nuclear bomb. Netanyahu, speaking on two US political talk shows, pressed the need for a categorical bar on Iran making a weapon, saying such a safeguard had averted nuclear calamity with Russia during the Cold War and could ensure peace again. The US says all options - including military action against Iran - remain on the table, but top officials reject so-called "red lines" as political grandstanding that might leave them at a strategic disadvantage. On CNN and on NBC's "Meet the Press", Netanyahu maintained that telling Iran there is a definite line it must step back from would serve as a pre-emptive and effective deterrent. "If they know there's a point, a stage in the enrichment or other nuclear activities that they cannot cross because they'll face consequences, I think they'll actually not cross it," he told CNN's "State of the Union". "It's important to put a red line before them, and that's something we should discuss with the United States." The Israeli leader said Iran was moving rapidly to finish enriching enough uranium needed to produce a nuclear bomb. "In six months or so, they'll be 90 per cent of the way there," he said. But his call for a change of tack and stiffer warnings from Washington was rejected by Susan Rice, the US ambassador to the United Nations. Rice, who spoke on five separate television talk shows, maintained there was "no daylight" between the US and Israel on preventing Iran from acquiring a nuclear weapon, but her comments on the timeline of Tehran's ambitions jarred with Netanyahu's. "We think that there's still considerable time for this pressure to work," Rice said, refusing to acknowledge the red lines argument and insisting that US sanctions were effectively hobbling Iran's currency and oil production. But she added: "This is not an infinite window, and we've made very clear that the president's bottom line is Iran will not have a nuclear weapon." Israel has consistently said a nuclear-armed Iran would pose an existential threat to its existence and has wielded the suggestion of unilateral military action, but the US favours sanctions and diplomatic arm-twisting. Iran has steadfastly denied that it is seeking the bomb and says its uranium enrichment program is meant for medical and energy uses. Relations between Netanyahu and President Barack Obama are viewed as frosty, and US Defence Secretary Leon Panetta further highlighted policy differences in an interview published on Friday. "The fact is, look, presidents of the United States, prime ministers of Israel or any other country - leaders of these countries don't have, you know, a bunch of little red lines that determine their decisions," Panetta said. "What they have are facts that are presented to them about what a country is up to, and then they weigh what kind of action is needed to be taken in order to deal with that situation," he told Foreign Policy magazine. "That's the real world. Red lines are kind of political arguments that are used to try to put people in a corner." The White House was forced in recent days to deny a report that Obama had refused to meet Netanyahu in New York City later this month and said the two spoke by telephone on Tuesday and were united in their stance toward Tehran.
