Russia, the international lender?;

As the past three years have shown, President Barack Obama and his predecessor, George W. Bush, don't often see eye-to-eye on foreign policy. On at least one issue, however, the two appear to be in full agreement. Both have stated clearly and repeatedly that the radical, revolutionary regime that rules Iran must not be permitted to acquire nuclear weapons. And yet, neither the current president nor the previous one made serious headway on this most serious of national security challenges.

The International Atomic Energy Agency’s latest report on Iran’s nuclear program has refocused world attention on the Iranian regime’s relentless pursuit of the bomb and on the global failure thus far to derail it. But a multilateral solution to the Islamic republic’s nuclear ambitions appears to be as elusive as ever, due in no small measure to the stances of its enablers — Russia among them. In recent days, Moscow has publicly rejected the new IAEA findings and argued for renewed diplomacy in response to Iran’s nuclear transgressions.

TODAY, the International Atomic Energy Agency released a report on Iran’s nuclear program. It provides the most convincing evidence to date that Iran is close to producing a nuclear weapon.

But as Iran nears the nuclear threshold, the best way to stop it may be by punishing the Chinese companies that supply Tehran and enable its nuclear progress.

It is something of a truism that in Washington, bad ideas never truly go away. Instead, they keep cropping up at the most inopportune moments. So it is with American policy toward Iran. Stymied in recent months by the resilience of Iran's increasingly mature nuclear effort and complicated by the unfolding turmoil of the “Arab Spring,” policymakers inside the Beltway are once again flirting with the idea that some sort of diplomatic rapprochement with the Islamic Republic is in fact possible.

Does the Islamic Republic of Iran pose a cyber threat to the United States? On the surface, the idea seems far-fetched. Squeezed by sanctions over its nuclear ambitions, suffering from widespread social malaise and weathering unprecedented divisions among its leadership, Iran hardly seems an imminent threat to the U.S. homeland - even if it does pose a vexing challenge to American interests in the greater Middle East.

Yet mounting indicators suggest that Iran's leadership is actively contemplating cyberwarfare against America and its allies.

Are sanctions capable of derailing Tehran's nuclear drive? Some skeptics reject such measures altogether, preferring to deal with Tehran by either accommodation or containment. Others point to the spotty historical record of sanctions in altering state behavior in arguing that they will similarly fall short of forcing the ayatollahs to rethink their long-standing nuclear ambitions. For example, sanctions were found to be successful in only a third of the 105 instances in which they were applied between World War I and the end of the Cold War.

As the past year has shown, however, Tehran may well turn out to be the exception to the rule—but only if the Obama administration (and Western governments more generally) make swift and skillful use of the economic and strategic means at their disposal.

With the drama of the Arab Spring and the death of Osama bin Laden dominating the headlines, you might have missed the most important development in months surrounding Iran's nuclear program: Zimbabwe's emergence as a key enabler of the Islamic Republic's march toward the atomic bomb.

In recent days, officials in Harare have confirmed that the government of Robert Mugabe is finalizing a massive resources deal with Tehran, in defiance of United Nations sanctions aimed at derailing Iran's nuclear push. That agreement, in the works since Iranian President Mahmoud Ahmadinejad visited the African state in April 2010, would provide the Iranian regime with preferential access to the country's estimated 455,000 tons of raw uranium over the next five years.

The deal sheds light on what amounts to a major chink in the Islamic Republic's nuclear armor. For all of its atomic bluster, the Iranian regime lacks enough of the critical raw material necessary to independently acquire a nuclear capability. According to nonproliferation experts, Iran's known uranium ore reserves are limited and generally of poor quality. It desperately needs steady supplies of uranium ore from abroad, and without those supplies the Islamic Republic's nuclear plans would, quite simply, grind to a halt.
