Many of Washington’s more hawkish voices have sought to downplay or drown out discussions about a possible military attack on Iran’s nuclear program. Even as the Obama administration has kept all options on the table regarding iran’s nuclear program, presumptive GOP nominee Mitt Romney’s campaign attacked the administration for trying to have an honest discussion of the possible consequences of a military strike.

Now, three Members of Congress — Reps. John Conyers (D-MI), Keith Ellison (D-MN), and Barbara Lee (D-CA) — are introducing an amendment to an intelligence authorization bill that would demand a government report about the possible consequences of an attack. Conyers and Ellison, among others, also used the amendment process to tag the Defense authorization — another big appropriations bill likely to pass — with language stating that Congress was not authorizing war with Iran.

The first public comments by members on the amendment, which has the support of pro-peace groups, could come this afternoon when the Rules Committee meets to decide on its inclusion in the larger bill. The amendment, Section 306 of the new bill, reads in full that:

Not later than 60 days after the date of the enactment of this Act, the Director of National Intelligence shall submit to the congressional intelligence committees a report containing an assessment of the consequences of a military strike against Iran.

The Director of National Intelligence James Clapper has already said that Iran has not made a decision to build a nuclear weapon — an estimate in line with reported U.S. assessments and also the U.N. atomic watchdog and Israeli assessments — and made clear that he thinks Iran can be dissuaded from building a bomb.

But his views on the consequences of a strike are unlikely to satisfy militaristic voices in Congress. Sen. Lindsey Graham (R-SC), a prominent hawk on Iran, publicly disagreed with Clapper’s Iran assessments during a hearing this winter. Last year, Graham called on Clapper to resign.

While President Obama, like others, considers a potential Iranian nuclear weapon a threat, this Spring he lamented the “loose talk of war” and called on those who are pushing an attack on Iran to hold open discussions about the possible consequences:

If some of these folks think that it’s time to launch a war, they should say so and they should explain to the american people exactly why they would do that and what the consequences would be.

Instead of hawkish bluster, the Obama administration maintains its options while pushing a negotiated diplomatic solution, which the administration considers the “best and most permanent way” to end the crisis. That’s because Israeli and American experts have noted that attacking could push Iran into building a weapon, and potentially ignite a regional war. Those are exactly the sorts of potential consequences of an attack on Iran that the Obama administration has called for a forthright conversation on, which Conyers, Ellison and Lee are now bolstering. And its exactly the conversation the hawks don’t want to have.

After a massacre of civilians on Friday night in Syria — including dozens of children — which the U.N. strongly hinted was perpetrated by government forces, presumptive GOP presidential nominee Mitt Romney blamed the Obama administration for not taking decisive enough action against the Syrian regime.

The plan Romney and his aides proposed to deal with the crisis, however, sounds a lot like the one Obama administration officials discussed with press just a few days before. “The United States should work with partners to organize and arm Syrian opposition groups so they can defend themselves,” the campaign said in a release on Sunday. On CNN this morning, top Romney aide Andrea Saul echoed the call, saying that Romney would “work with our allies to help arm the Syrian opposition.” Watch it:

If all that sounds familiar, it might be because, three days before the Romney statement, that’s exactly what Obama administration officials told the AP they were setting a plan in motion to do. The AP reported:

[T]he Obama administration is preparing a plan that would essentially give U.S. nods of approval to arms transfers from Arab nations to some Syrian opposition fighters.

The effort, U.S. officials told the Associated Press, would vet members of the Free Syrian Army and other groups to determine whether they are suitable recipients of munitions to fight the Assad government and to ensure that weapons don’t wind up in the hands of al-Qaida-linked terrorists.

As for the goal of pushing for a transition in Syria, the New York Times reported on Saturday — the day before Romney’s statement — that ” President Obama will push for the departure of President Bashar al-Assad.”

The Romney campaign “doesn’t want to really engage” on foreign policy issues. Perhaps that’s because so many of his proposals sound like what the Obama administration is already doing — albeit with more hawkish bluster. Last month, Vice President Biden, while criticizing Romney’s “loose talk of war,” noted that, other than the rhetoric, the policies were the same: “Governor Romney has called for what he calls a ‘very different policy’ on Iran. But for the life of me it’s hard to understand what the governor means by a very different policy.”

It is said that, to Washington’s neoconservative pundits, every problem looks a nail, and they have just the hammer: military force. Washington Post columnist and Fox News commentator Charles Krauthammer nicely encapsulated this concept last night on Bill O’Reilly’s show when he said that the U.S. should have sent “weaponry” to the pro-democracy movement that erupted in Iran after the fraudulent presidential elections of June 2009.

Krauthammer said that President Obama should have ramped up rhetoric against Iran during the brutal crackdown on the Green Movement — the distinctly non-violent protest movement born out of Mir Hossien Moussavi’s failed 2009 presidential campaign. And when O’Reilly asked what else Obama could have done, Krauthammer said he should have armed the protesters and order a covert war against Iran:

O’REILLY: But what else could he have done except rhetoric?

KRAUTHAMMER: Weaponry — he could have done a lot of things. Rhetoric is one thing and not to support the legitimacy of the regime. Clandestine operations. Why do we have $50 billion in secret operations in the CIA if not for an opportunity like this? He was hands off. He did nothing and we lost one of the great opportunities in history.

Watch the video:

Presumptive GOP presidential nominee Mitt Romney and his ideological comrades have made President Obama’s reaction to the 2009 post-election Iranian government crackdown on Green Movement demonstrators a centerpiece of their criticisms. Romney’s campaign issue page for Iran says Obama “refrained from supporting the nascent Green Movement.” In a Washington Post op-ed, Romney wrote that he would “speak out on behalf of the cause of democracy in Iran and support Iranian dissidents who are fighting for their freedom.”

In reality, Obama didn’t, as Krauthammer put it, “support the legitimacy of the [Iranian] regime.” Daniel Larison has pointed out that, when failed presidential candidate Rick Santorum made the same charge, that unlike many world governments, Obama never recognized the elections. Furthermore, Obama condemned the abuses against demonstrators that June.

But more to the point, one hopes that Romney does not conflate symbolic “fighting” for freedom with literal fighting. Unlike in Syria and Libya, the Green Movement in Iran never took up arms. As Ardeshir Amirarjmand, a top adviser to Moussavi now in exile in France, told an audience at MIT last year, “We do not have any other choice than a nonviolent path toward democracy.” Or, as University of Toronto professor Ramin Jahanbegloo put it, “The Green Movement faces a troubling situation, but it is banking on its strategy of nonviolence as moral capital.” Iranian human rights lawyer and Nobel Laureate Shirin Ebadi — who, like Iranian civil society as a whole, opposes attacking Iran — told ThinkProgress in 2010 that she disagreed with critics who said that Obama should have spoken more forcefully in support of the Green movement in June 2009.

Krauthammer worries that Obama is not doing enough to support Iran’s democracy movement. But it’s perfectly clear that the Green Movement doesn’t want the kind of support — weapons and covert war — that Krauthammer is offering.
