Obama came out with these statements in 2004:
Obama said the United States must first address Iran's attempt to gain nuclear capabilities by going before the United Nations Security Council and lobbying the international community to apply more pressure on Iran to cease nuclear activities. That pressure should come in the form of economic sanctions, he said.
But if those measures fall short, the United States should not rule out military strikes to destroy nuclear production sites in Iran, Obama said.
... Obama conceded that such strikes might further strain relations between the U.S. and the Arab world.
"In light of the fact that we're now in Iraq, with all the problems in terms of perceptions about America that have been created, us launching some missile strikes into Iran is not the optimal position for us to be in," he said.
"On the other hand, having a radical Muslim theocracy in possession of nuclear weapons is worse. So I guess my instinct would be to err on not having those weapons in the possession of the ruling clerics of Iran. ...
...if President Pervez Musharraf (Pakistan) were to lose power in a coup, the United States similarly might have to consider military action in that country to destroy nuclear weapons it already possesses.
Obama said that violent Islamic extremists are a vastly different brand of foe than was the Soviet Union during the Cold War, and they must be treated differently.
"With the Soviet Union, you did get the sense that they were operating on a model that we could comprehend in terms of, they don't want to be blown up, we don't want to be blown up, so you do game theory and calculate ways to contain," Obama said. "I think there are certain elements within the Islamic world right now that don't make those same calculations."

Granted, Iran is projected to not being able to have a working nuclear program for up to 10 years.
Perhaps Frank wouldn't give a rat's ass if nukes were in the hands of suicidal maniacs blinded by theocratic morass. But any President should certainly weigh out the possibility.
Making the Middle East a nuclear-free zone (including Israel) would be my first effort if I was President. I would think that Obama would want to go in that direction.
Bumperstickering Obama (and even Edwards and H. Clinton) as wanting to attack Iran given the chance is bunk. Diplomatic strategies and other counter-measures within the UN would be the first choices.
