A senior Israeli official laid out the terms Tel Aviv would accept in a deal to curtail Iran's nuclear bomb ambitions.
Israeli Vice Prime Minister Shaul Mofaz, speaking at a forum in Washington, described the steps Iran must take to appease hawkish Israeli officials who want to unleash a military strike on Tehran's nuclear facilities this year.
Iran would have to agree to cease all enrichment of uranium, give up all its enrichment equipment, and also "remove all underground facilities," Mofaz said.
It is unlikely Iranian leaders will accept the terms.
The Kadima Party leader's proposal on enrichment is even stricter than one put forth during talks with Western nations last month during talks in Baghdad. Iran rejected that plan.
The Obama administration and its allies have been moving forward with a strategy to convince Iran to stop its nuclear arms effort by implementing ever-tougher sanctions. Administration officials and experts say those measures are having an impact, and have made Tehran more serious in ongoing talks with the Western powers.
Tougher sanctions, including ones on its oil industry by Europe, will be fully implemented in early July.
But the sanctions-based approach, coupled with monthly talks like those this week in Moscow, constitute a long-term plan. Israeli officials, GOP American lawmakers and Middle East experts warn this allows Iran to buy time to continue work on its atomic arms.
Will Tel Aviv wait for President Obama's long game to play out?
"There is no way Israel will accept a nuclear Iran," Mofaz said. "If Iran becomes nuclear, it will become a different world."
"Just because you have tougher sanctions doesn't mean we have four or five months," Mofaz added. "We have limited time."
