Senators push U.S. to act in Libya

WASHINGTON — Congressional leaders prodded the Obama administration on Sunday for a more aggressive U.S. response to Libya's increasingly brutal attacks on opposition groups — calling for a no-fly zone and other military measures — but White House officials cautioned against being drawn into a potentially protracted and costly military campaign.

Meanwhile, forces loyal to Moammar Gadhafi, some in helicopter gunships, pounded opposition fighters with artillery, rockets and gunfire Sunday, dramatically escalating their counteroffensive to halt the rebels' rapid advance toward the capital. The expanding campaign appeared to dash rebel hopes to put a swift end to his 41-year rule.

In the United States, Sen. John Kerry, D-Mass., chairman of the Foreign Relations Committee, for the first time raised the possibility of bombing military airfields in Libya to deny the use of runways to Gadhafi's air force. Two of the Senate's top Republicans, Sens. Mitch McConnell, R-Ky., and John McCain, R-Ariz., also argued forcefully for U.S. military involvement to keep Libyan warplanes grounded.

"We can't risk allowing Gadhafi to massacre people from the air," McCain, the ranking Republican on the Armed Services Committee, said on ABC's "This Week with Christiane Amanpour."

But White House officials appeared to play down expectations for an expanded U.S. military role in the immediate future. While insisting that no options have been ruled out, White House Chief of Staff William Daley cited the difficulty of enforcing a no-fly zone over Libya, a vast country armed with modern, Russian-supplied antiaircraft defenses.

"Lots of people throw around phrases like 'no-fly zone,' " Daley said on NBC's "Meet the Press" news program. "They talk about it as though it's just a video game."

Daley's remarks echoed the caution voiced by Defense Secretary Robert Gates, who dismissed as "loose talk" the clamor for a U.S.-led air campaign. Any effort to secure the skies over Libya would have to begin with military strikes on Gadhafi's air-defense network and would inevitably lead to an expanded U.S. mission in a country roughly the size of Alaska, Gates said.

Kerry and other senators argued Sunday that Libya's air force could be disabled without the kind of expense and commitment required to maintain previous no-fly zones in Iraq and the Balkans. The Massachusetts Democrat also called for turning over to rebel groups some of Gadhafi's estimated $30 billion in frozen assets.

A no-fly zone is "not the only option for what one could do," Kerry said.

"One could crater the airports and the runways and leave them incapable of using them for a period of time," he said.

The debate over U.S. options highlights the dilemma facing the Obama administration as Libya veers closer to all-out civil war. The White House is confronting a range of options, including increased humanitarian aid and different gradations of military intervention, although none is likely to end the violence immediately, administration officials concede.

Nor is the United States likely to gather enough international support in the short term to quickly push Gadhafi from power, the sources said. U.N. Security Council members Russia and China have objected to any military action authorized by the United Nations, as has Brazil. The Arab League has also spoken out against any Western-backed military intervention and raised the possibility of imposing a no-fly zone with the nations of the African Union.

Senior administration officials say days of fighting — along the east-west coastal road to Tripoli and in and around the capital itself — have resulted in a strategic deadlock on the ground. The Obama administration is not ready yet, though, to call the situation a civil war.
