Netanyahu also said the U.S. should retain its harsh economic sanctions against Iran until it dismantles its nuclear program. "That's what got them into these renewed negotiations in the first place," he said. Obama administration officials are weighing whether to ease some sanctions even as some U.S. lawmakers in Congress are eyeing plans to tighten the economic hurdles if Iran takes steps to scale back its program.
Kerry, who spent the last three days in meetings with European and Mideast officials that focused mostly on Iran and Syria, said the U.S. would continue to do everything it can to prevent Tehran from building nuclear weapons. But he stopped short of agreeing with Netanyahu's demands.
"We will need to know that actions are being taken which make it crystal clear, undeniably clear, failsafe to the world, that whatever (Iranian) program is pursued is indeed a peaceful program," Kerry said. "No deal is better than a bad deal. But if this can be solved satisfactorily, diplomatically, it is clearly better for everyone."
Neither Israel nor Saudi Arabia has been included in the world powers' negotiations with Iran.
Senior Saudi officials this week described a widening gulf between Washington and Riyadh over U.S. policy in Iran and Syria. Saudi Arabia also wants the U.S. to send more military support to opposition groups seeking to oust Assad from power as an end to Syria's 2 civil war that has killed more than 100,000 people. The Iranian government has been the key benefactor to Assad, and has sent military forces, weapons and funding to support his government against the rebellion.
Both the U.S. and Saudi Arabia are working to start talks between Assad and opposition leaders to create a new government in Syria that, ultimately, would not include Assad. Syrian National Coalition President Ahmad al-Jarba on Tuesday told reporters in London that he was not ready to agree to the negotiations, but opposition officials will vote on whether to participate in coming days.
The impasse over the Syrian negotiations comes as a team of inspectors with the United Nations and the Organization for the Prohibition of Chemical Weapons work to dismantle Assad's chemical weapons stockpile, which is considered one of the world's largest, after a deadly Aug. 21 chemical weapons attack.
Kerry met with Saudi Foreign Minister Prince Saud al-Faisal in Paris on Monday in what he described as a "delightful and very, very constructive" discussion. He brushed off suggestions of diplomatic chilliness between the two nations.
On Iran, "I think they understand exactly what the United States is engaged in," Kerry said a day later in London when asked about tensions between Washington and Riyadh. "And I reiterated our position in any negotiation that our eyes are wide open, actions are what will speak to us, not words."
In Rome, Kerry and Netanyahu also discussed ongoing peace talks between Israel and Palestinian authorities who were meeting in Jerusalem even as officials warned about threats that would rise in the event of a stalemate.
Netanyahu said any agreement must result in "a peace that Israel can defend by itself, for itself against any conceivable threat." He called the creation of a Palestinian state "a fundament for any peace." Kerry praised Netanyahu and Palestinian President Mahmoud Abbas for engaging in negotiations but offered no details.
Back in Israel, Netanyahu chief negotiator Tzipi Livni described a growing international impatience with the peace process during a speech to visiting Jewish leaders from around the world. She noted that Israeli settlement construction is causing great damage to Israel's international image, and that a stalemate could lead to a "world supporting the Palestinians, not just as a vague idea of a Palestinian state."
"So stalemate can lead to a Palestinian state that would be forced on us, not as the outcome of negotiations that represent the Israeli interest, but as something that the world would force us to accept," Livni said.
