The U.S. envoy to the IAEA, Ambassador Glynn Davies, said in Vienna on Friday that international patience with Iran was running out and that "round after round" of fruitless talks could not continue.
Speaking to reporters in Washington later, the U.S. official said the vote showed "unity of purpose" among major international powers on Iran, and repeated that time was growing short for Tehran to come clean about a nuclear program that Western governments fear is aimed at producing nuclear weapons. Iran denies the charge.
The official declined to be drawn on what sort of consequences were being contemplated, although British Prime Minister Gordon Brown said harsher sanctions could be on the way if Iran ignored the IAEA vote.
U.S. President Barack Obama and European leaders have given Iran until the end of the year to begin talks on the nuclear stalemate.
Once we are actually spending billions and losing thousands of lives, the impatience suddenly evaporates.
Obama is likely to add at least 30,000 to a force that will total 100,000 in Afghanistan. An equal number will remain in Iraq, meaning last year's anti-war candidate will ironically have more soldiers in harm's way - 200,000 - than Bush did at the height of the Iraq "surge."
And don't call this boost a "surge" because insiders know that's a misnomer.
It will be an escalation without any plan on the horizon to draw down the additional forces, like in Iraq.
[Peter] Bergen says the extra troops can secure more roads and pockets thick with Taliban in the next two years, but ending the war "is a long-term project."
It's not just how many boots are on the ground, it's how they're used.
That's why many strategists are embracing the idea of hiring Pashtun tribal militias or embedding Special Forces to "go native" for years and win tribal allies by spilling blood with them side by side.
But the wisest ideas all involve facing the hard truth that we will be in the fight for many more years amid polls that show the public - American and Afghan - losing patience.
That hard dose of reality required to win gives the enemy plenty of ammo in the meantime for their propaganda denouncing Americans as occupiers who refuse to leave.
