Will U.S. implement a no fly zone?

Recent days have heard much talk of a no-fly zone over the skies of Tripoli. On Sunday, Senate Foreign Relations Committee Chairman John Kerry called for the bombing of Libya's airstrips.

On Tuesday, 2008 presidential candidate Sen. John McCain continued his push for a no-fly zone, and some have suggested that Obama is dragging his heels in making a decision. White House Press Secretary Jay Carney on Tuesday repeated that the administration is "considering all options, including military options."

"There are complexities and realities involved in the adoption and implementation of a measure like a no-fly zone that we all need to be aware of as we consider it," he said at a press gaggle aboard Air Force One.

"It is an option we are actively considering. It is also one that carries with it complexities and other things that everyone needs to be aware of."

If Obama does take action, it would not be unilateral but rather encompass an international coalition, although Carney declined to comment on whether that would include a UN Security Council resolution.

The White House is currently working with its global partners "on a number of measures," including ones that involve humanitarian assistance, as well as the "very serious sanctions that we've leveled," he said. "So our interest is in working with our international partners going forward."

Complicating the issue, however, is that no clear leader is emerging in Libya that the United States and the Europeans see as a viable alternative to Gadhafi, Bhalla said.

"That's why we are seeing this reticence among the U.S. and the Europeans, because they don't know who in the opposition they can work with," she said.

So for now, the United States and its allies sit and wait, continuing to focus a sharp eye on the region, she said.
