Moammar Gadhafi vowed a "long war" as allied forces launched a second night of strikes on Libya on Sunday, and jubilant rebels who only a day before were in danger of being crushed by his forces now boasted they would bring him down. The U.S. military said the international assault would hit any Gadhafi forces on the ground that are attacking the opposition.

The U.S. military said the bombardment so far — a rain of Tomahawk cruise missiles and precision bombs from American and European aircraft, including long-range stealth B-2 bombers — had succeeded in heavily degrading Gadhafi's air defenses.

U.S. Defense Secretary Robert Gates said Sunday that the U.S. expects to turn control of the Libya military mission over to a coalition — probably headed either by the French and British or by NATO — "in a matter of days."

In his first public remarks since the start of the bombings, Gates said President Barack Obama felt very strongly about limiting America's role in the operation, adding that the president is "more aware than almost anybody of the stress on the military."

"We agreed to use our unique capabilities and the breadth of those capabilities at the front of this process, and then we expected in a matter of days to be able to turn over the primary responsibility to others," Gates told reporters traveling with him to Russia. "We will continue to support the coalition, we will be a member of the coalition, we will have a military role in the coalition, but we will not have the preeminent role."

The two key possibilities, he said, are a combined British-French command or the use of a NATO command. He acknowledged there is "some sensitivity on the part of the Arab League to being seen to be operating under a NATO umbrella."

Asked about working with the rebels, and whether the coalition knows enough about them to forge a partnership, Gates said Libyans must ultimately resolve matters themselves — though it remains to be seen what additional outside help will be provided.

Still, he added, "We certainly know a lot about Gadhafi, and that's good enough for me."

Asked if the bombings should target Gadhafi, Gates said the coalition should stick to the objectives in the U.N. Security Council resolution, and adding new ones would create a problem. "It is unwise to set as specific goals things that you may or may not be able to achieve," he added.

He said most nations want to see Libya remain a unified state.

"Having states in the region begin to break up because of internal differences, I think, is a formula for real instability in the future."

The military assault on Libya began Saturday with the launch of about 112 Tomahawk cruise missiles from U.S. and British ships, followed by a coordinated air assault by U.S. warplanes — including Air Force B-2 stealth bombers and Marine attack jets in the pre-dawn hours.

Adm. Mike Mullen, chairman of the Joint Chiefs of Staffs, described the campaign's aims as "limited," saying it "isn't about seeing him (Gadhafi) go."

Gadhafi has vowed to fight on, promising a "long war," and his troops have lashed back, bombarding the rebel-held city of Misrata with artillery and tanks on Sunday, the opposition reported.
