The Obama administration says the internal unrest in Iran and signs of unexpected delays in their nuclear program make the Iranian government especially vulnerable to swift and serious sanctions, the New York Times reported on Sunday.
An administration official said current circumstances "give us a window to impose the first sanctions that may make the Iranians think the nuclear program isn't worth the price tag."
Despite the political unrest, Iran's political and military leaders are remaining steadfast in their determination to develop nuclear weapons, advisers to U.S. President Barack Obama said. But the unrest coupled with the Iranian government's internal turmoil has caused a deceleration in production of nuclear fuel in recent months.
The White House is interested in focusing new sanctions on Iran's Islamic Revolutionary Guard Corps, which is thought to be the driving force behind the country's nuclear weapons program.
The administration also believes that efforts to develop nuclear weapons suffered a major setback when Iran's undisclosed uranium enrichment plant in Qom was exposed three months ago. According to officials, the outing prevented Iran from enriching uranium at the high levels necessary for creating fuel for a nuclear weapon.
Nuclear inspectors also report that at Iran's plant in Natanz, the operation of uranium enrichment centrifuges has dropped by 20 percent since the summer, which experts attribute to technical problems.
Experts have been continuously speculating how long it would take Iran to develop a nuclear weapon. One senior expert said, "For now, the Iranians don't have a credible breakout option, and we don't think they will have one for at least 18 months, maybe two or three years."
The U.S. believes the longer time frame allows more time for the sanctions to affect Iran before they are able to develop a nuclear weapon.
Israel's Washington ambassador says military option on Iran not yet on the table
On Thursday, Israel's ambassador to Washington, Michael Oren, said U.S.-Israeli dialogue on Iran has not reached the point of discussing a military option to thwart its nuclear ambitions.
Oren said that the focus was instead on sanctions against Iran in 2010.
"I'm very confident in America's commitment to dissuading Iran from enriching uranium on its soil, which is our common goal," Oren told Reuters in a telephone interview.
"Our positions on Iran completely dovetail and we have very close cooperation and communication," he added. "Right now the main focus is on the formulation and the application of the sanctions. That's where we are."
