It will take even tougher talks if the much-criticized and fragile first agreement is to become a long-term deal that will come closer to mollifying all sides.

GENEVA – Turning the fragile preliminary agreement on Iran's nuclear program into a stringent long-term deal will require even harder negotiations than those in the arduous months leading up to Sunday's signing ceremony in Geneva.

New issues will be added to the complex mix even while the two sides try to maintain enough momentum to avoid having their temporary deal settle into a slightly altered status quo that satisfies no one. And the talks will take place amid fierce crossfire from critics on both sides.

The criticism became apparent within hours of the deal as Israeli Prime Minister Benjamin Netanyahu attacked it as a"historic mistake" that makes the world a "much more dangerous place."

The Obama administration and its partners from Britain, France, Germany, Russia and China had agreed to weaken international sanctions against Iran in return for "cosmetic Iranian concessions that can be canceled in weeks," Netanyahu charged.

The preliminary deal requires a pause in Iran's effort to build its nuclear capacity by enriching uranium. It rolls back some elements of that country's nuclear program and subjects it to daily international inspections. But the pause comes at a point where analysts believe Iran already has gotten within a few months of having enough enriched uranium to test a nuclear device, should it decide to do so.

The prospect of Iran being that close to acquiring bomb-making capability deeply disturbs Israel, as well as Saudi Arabia and other Arab states in the Persian Gulf.

Because of the deep suspicion of Iran's motives on the part of long-standing allies, U.S. officials have emphasized that the current agreement is just a means to a deal that would permanently move Iran away from the ability to make a nuclear weapon.

President Obama called Netanyahu on Sunday to discuss the deal. The White House said Obama told Netanyahu that he wanted the two countries to begin consultations on the next round of negotiations and that Israel "has good reason to be skeptical about Iran's intentions."

The administration and its allies hope that the agreement will gradually gain support and build momentum. Lifting some sanctions on Iran's economy will build a constituency within Iran for more relief, they hope. At the same time, stringent inspections of Iran's nuclear sites could build support in the U.S. and elsewhere for further negotiations.

But the opposite could also happen. If the talks bog down, momentum could slow and the administration could end up simply extending the current arrangement so that it becomes a long-term status quo.

That would not satisfy either side.

Settling for the interim agreement over the long term would leave the effort to curb Iran's nuclear program in an uncomfortable limbo, neither permitting a breakout, as happened with North Korea in 2006, nor achieving a total rollback of the nuclear program, as happened in Libya in 2003.

The Geneva agreement calls for negotiating a final deal within one year and says the preliminary six-month deal can be renewed by mutual consent. Many analysts believe that extending the existing deal at least once is likely because of the complexity of the negotiations. Administration officials insist, however, that they won't renew it indefinitely and are ready to call a halt if they do not make headway.

To clinch the final deal, the U.S. and its allies will have to persuade Iran to agree to far-reaching dismantling of much of a nuclear infrastructure that has cost billions of dollars and become a symbol of national pride.

The current agreement imposes tough new monitoring requirements, including daily visits by inspectors to enrichment facilities; but the comprehensive deal would be even more intrusive.

A permanent deal would also require settling other issues that have not received much attention so far, such as how long the final deal will last. Iran would like to see a half-decade deal, followed by much more permissive treatment of its nuclear program. Many government officials in the West would like the deal to require intensive inspections and controls on Iranian technology that would last half a century or longer.

Other issues could undermine the talks, as well.

Iranians hope the comprehensive deal will resuscitate their economy, which shrank more than 5% last year. But even if tough sanctions on banking and oil exports are lifted, the United States will still retain punishing sanctions that block investment in Iran's energy industry.

Those sanctions were imposed because of Iran's support for groups the U.S. regards as terrorist organizations, noted Ali Vaez, an Iran specialist at International Crisis Group in Istanbul, Turkey. Congress will be unlikely to lift them unless Iran ends support for groups such as Hezbollah in Lebanon, which is a key regional ally.

It's also unclear whether either Obama or Iranian President Hassan Rouhani has the political power necessary to prevail over hard-line opponents.

In the U.S., many top lawmakers who have been advocates of sanctions said Sunday that they intend to hold off for six months on imposing new sanctions. But if they don't see Iranian compliance or cooperation in the bargaining ahead, they will add sanctions, lawmakers said.

Such steps by Congress could set off a vicious cycle in which Iranians feel they have to retaliate, and political support erodes. Rouhani has the backing of supreme leader Ayatollah Ali Khamenei for the moment, but whether that support will last remains to be seen.

Congressional critics of the deal might also be unsettled by some of its features. For example, the "joint plan" that spells out the deal puts down in black and white that a final solution of the issue "would involve a mutually defined enrichment program, with practical limits and transparency measures."

U.S. officials have been hinting for some time that they might accept a limited Iranian enrichment program if Iran met other international nuclear requirements. But so far they haven't had to formally address the issue in this way.
