Top administration officials, leading lawmakers, and GOP presidential candidates have all weighed in on Sen. John McCain's proposal to launch U.S.-led airstrikes to halt the violence in Syria, but there is still no consensus on the costs and benefits of entangling the U.S. military in another armed conflict.
"Just as was the case with Libya, there is a broad consensus among regional leaders and organizations on the preferred outcome in Syria: Assad and his cronies must go. There is not, however, a consensus about how this goal could be achieved," Sen. Carl Levin (D-MI) said at Wednesday's Senate Armed Services Committee hearing with Defense Secretary Leon Panetta and Joint Chiefs Chairman Gen. Martin Dempsey.
Levin didn't say whether he was for or against a U.S.-led military intervention in Syria, but he warned of the risks and talked about the possible impact on the region.
McCain was more clear, repeating his call for foreign air power to be used against the forces of President Bashar al-Assad, and calling for the immediate arming of the Syrian opposition -- hopefully with international cooperation from Arab partners and European allies.
"It is understandable that the administration is reluctant to move beyond diplomacy and sanctions. Unfortunately, this policy is increasingly disconnected from the dire conditions on the ground in Syria, which has become a full state of armed conflict," McCain said.
He urged Panetta to remember his time as White House chief of staff during the NATO intervention in Bosnia and quoted President Bill Clinton as saying at the time, "There are times and places where our leadership can mean the difference between peace and war and where we can defend our fundamental values as a people and serve our most basic strategic interests. There are still times when America and America alone can and should make the difference for peace."
McCain also quoted CENTCOM chief Gen. James Mattis, who testified Tuesday that "Assad is clearly achieving what he wants to achieve" that his military campaign is "gaining physical momentum on the battlefield." Mattis also noted that Assad's downfall would be "the biggest strategic setback for Iran in 25 years."
In his testimony, Panetta clearly ruled out any unilateral military action by the United States in Syria, but he left the door wide open to a multilateral mission inside Syria at some later date. Yesterday, President Barack Obama said that no option in Syria has been taken off the table.
"We are reviewing all possible additional steps that can be taken with our international partners to support the efforts to protect the Syrian people, to end the violence, and ensure regional stability, including potential military options, if necessary," Panetta said. "Currently, the administration is focusing on diplomatic and political approaches rather than military intervention."
"We need to have a clear legal basis for any action that we take. For us to act unilaterally would be a mistake," Panetta said. "Can it happen today? Can it happen now? No. It's gonna take some work; it's going to take some time. But when we do it, we'll do it right. We will not do it in a way that will make the situation worse. That's what we have to be careful of."
Dempsey said the Pentagon has planned for several possible military actions in Syria, including delivering humanitarian relief, imposing a no-fly zone, conducting maritime interdiction, establishing humanitarian corridors, and executing limited air strikes. He said the planning was at a "commander's estimate level of detail," and that there had been briefing to the National Security Council staff but not the president directly.
"As you know, we're extraordinarily capable and we can do just about anything we're asked to do," Dempsey said. "The ability to do a single raid-like strike would be accessible to us. The ability to do a longer-term sustained campaign would be challenging, and would have to be made in the context of other commitments around the globe."
Dempsey also confirmed elements of The Cable's Tuesday story on Syria, including the fact that Russia continues to arm the Syrian regime, including with advanced air defense systems.
Panetta said he believed that NATO should start debating the issue of a military intervention in Syria. That discussion so far has not begun in Brussels, according to NATO Secretary-General Anders Fogh Rasmussen. Panetta also said the Pentagon will not begin planning for a Syria intervention in detail until directed to do so by the president.
"I don't think there's any question that we're experiencing mass atrocities there," Panetta added.
Yesterday, several top Republican politicians declined to go along with McCain's call for airstrikes on Syria now, including House Foreign Affairs Committee Chairwoman Ileana Ros-Lehtinen (R-FL), GOP presidential candidate Mitt Romney, and House Speaker John Boehner (R-OH).
In a short interview Tuesday, McCain said that didn't bother him one bit.
"I couldn't care less," McCain said. "I know the difference between right and wrong. I know that people are being slaughtered as we speak."
"I refer back to Bosnia and Kosovo. Under President Clinton, we acted although there were Republicans strongly opposed to that. I think it turned out well."
Sen. Lindsey Graham (R-SC), who joined McCain's call for airstrikes along with Sen. Joe Lieberman (I-CT), told The Cable Tuesday that he preferred a multilateral military intervention in Syria over a unilateral strike.
"The Arab League is the right vehicle," said Graham. "If they request air support I'm willing to be part of the team. But I want the Arab League and the international community to be deeply involved and I want it to be to stop the slaughter."
