Obama Confident Gadhafi Will Step Down

U.S. President Barack Obama said he is confident that Moammar Gadhafi will "ultimately" step down, as a new poll Wednesday found nearly half of Americans were opposed to U.S. military involvement in Libya.

Obama warned Tuesday he had not ruled out supplying arms to rebels seeking to oust him, and said the "noose is tightening" around the Libyan strongman.

He also noted, however, that it did not appear yet that Gadhafi was seeking to negotiate an exit from Libya, despite a fierce bombardment of his forces by an international coalition.

The Quinnipiac University survey found most voters were confident the U.S. mission to shield civilians from Moammar Gadhafi could succeed, though there was an undercurrent of concern about a long engagement, with 47 to 41 percent opposed to U.S. involvement in Libya.

The president gave interviews to three network television news shows as part of a firm defense of his Libya strategy, which included an address to Americans and coming appearances by his national security team in Congress.

Obama's comments reflected an apparent attempt by U.S. and allied forces to raise intolerable pressure on Gadhafi and his forces to drive him from power.

"Our expectation is that as we continue to apply steady pressure, not only militarily but also through these other means, that Gadhafi will ultimately step down," Obama said in his interview with NBC.

Obama cautioned in a speech to Americans on Monday, however, that though he would use force to protect civilians, an effort to oust Gadhafi by force would replicate the carnage and financial cost of the Iraq war.

His comments on Tuesday followed a major international conference on next steps in Libya in London where Italian Foreign Minister Franco Frattini told Agence France Presse that participants had "unanimously" agreed Gadhafi should leave Libya.

But Frattini said, as yet, no nation had made a formal proposal to offer Gadhafi exile.

Obama told ABC News that those around Gadhafi were being given cause to rethink their positions as his regime came under intense outside pressure.

"I think what we're seeing is that the circle around Gadhafi understands that the noose is tightening, that their days are probably numbered, and they are going to have to think through what their next steps are," Obama said.

Obama also confided that he was thinking through the idea of arming opposition rebels in Libya, though had yet to make a final decision.

"We're looking at all our options at this point," he said. "We are examining all options to support the opposition," he told ABC.

"I'm not ruling it out. But I'm also not ruling it in," he added on NBC, but cautioned that though Washington's knowledge of the identity, goals and make-up of the rebels was improving, it was not yet comprehensive.

Those members of the Libyan opposition who had met top U.S. officials, including Secretary of State Hillary Clinton, had been fully "vetted," he said. But some opposition individuals may be unfriendly to the United States, he added.

"That's why I think it's important for us not to jump in with both feet. But to carefully consider what are the goals of the opposition," Obama told CBS.

Earlier this week the U.S. military announced a shift from long-range guided missile attacks that have targeted command centers and anti-aircraft defenses, to low-flying combat aircraft designed for close-range assaults against ground troops, yet still insisted on denying it was directly supporting the rebels.

The aircraft are the A-10, designed for close air support, especially against tanks and armored vehicles, and the AC-130, a transport aircraft modified for close combat.

Any decision to arm Libyan rebels would cause intense international debate over whether an international arms embargo on Libya would preclude such action.

Britain's Prime Minister David Cameron has said the language of the embargo would not allow the supply of weapons. The White House has said, however, it believes the text does offer latitude to send arms to rebels.

Earlier, France's Foreign Minister Alain Juppe said his country was prepared to hold discussions with its allies over the possibility of supplying military aid to the opposition movement.

And rebel forces said late Tuesday that French and U.S. diplomatic envoys were headed to Benghazi, and said they were trying to procure arms from "friendly nations."
