Secretary of State Condoleezza Rice has defended as "successful" the US administration's policy on Iran after Democratic presidential candidate Barack Obama criticized its approach.
Though she tried to avoid commenting on the presidential campaign, Rice told reporters that the United States and other powers agreed on what she considers a common, effective approach to prevent Iran from obtaining a nuclear weapon.
"I will note that the Iranian problem is not just America's problem, it is an international issue, and it is an issue on which the international community is united in confronting Iran with choices before it," Rice said.
Flanked by British Foreign Secretary David Miliband, a US ally on Iran and other issues, Rice recalled that Tehran must either halt its enrichment of uranium in return for economic benefits or face international isolation.
With its continued defiance, she said, the UN Security Council has adopted three sanctions resolutions against Iran while the United States has taken punitive measures of its own.
And Iran has paid an economic price with the "drying up" of international investment in its oil industry, economic infrastructure and export credits, the secretary of state said.
"I think this is called a successful multilateral coalition of states that have the same view" that Iran should e rewarded for its cooperation or isolated for its defiance, Rice said.
She added: "I would like to see what other options there are for the international community, given that this policy is one that I think is the best course for us.
