Washington: US which cannot digest the fact that Iran is emerging as a nuclear power in comparison with United States has decided to build up continuous international pressure on Iran and isolate it further so that Tehran abandons its effort to pursue nuclear weapons, a top Obama Administration official said.

"We will keep up that pressure, and we will keep up the effort to work with our allies and partners to further isolate Iran, even as we make clear that there is a solution here, and that is for Iran to get right with the international community; that is for Iran to abandon efforts to pursue nuclear weapons," White House Press Secretary Jay Carney said.

"That's the path forward for Iran. We will continue the effort to isolate and pressure Iran, working with our international partners going forward. We think it's been effective," Carney told reporters, hoping that the Iranian leadership will choose the path of working with the international community to abide by its obligations.

Carney said there is no doubt that the concerted effort of this administration, working with its international partners and allies, to implement the most stringent sanctions against Iran in history have had a significant impact on Iran, on the its economy, and have contributed to the fissures within the Iranian leadership.

"They are also probably a precipitating factor in the kind of provocative statements and diversionary tactics that the Iranians have used to try to change the subject from the fact that they will not abide by their international obligations, and that is why they are the subject of this kind of pressure and this kind of isolation," he said on Tuesday.

Responding to questions, Carney said Israel is a key ally and partner, and has a profound interest in the effort to pressure Iran into abiding by its international obligations, as do many nations in the region and the world.

Carney was responding to news reports that the Obama Administration has asked Israel not to take a unilateral early strike against Iran.

"We have worked very closely with the Israeli government, with the Prime Minister, as we do on a number of issues, and we believe that the approach we've taken has put unprecedented pressure on Iran to change its behavior," it said.
