President Obama would face less opposition to military action in Libya if he would present a strong case for U.S. involvement, Sen. Joe Lieberman (I-Conn.) said Sunday.

"Even though [at] different times the administration has said that we're not interested in overturning Gadhafi, clearly, we are," Lieberman said. "This is all about regime change and freeing the people of Libya from another brutal — another time period when they'll be suffering brutal dictatorship.

"So — I know it's complicated. And I think, frankly, there wouldn't be as much opposition in Congress to our action in Libya if there was a strong argument being made on behalf of why we are there."

His comments on Fox News Sunday echo a Wall Street Journal op-ed last week in which Lieberman said the administration has not done enough to justify the intervention in Libya.

"The truth is, if we use our strength with our NATO allies, when you go in a fight, you can't be uncertain about it," Lieberman said Sunday. "If we use that strength, I think Gadhafi will go and it will be a tremendous step forward for the Arab world and the cause of freedom there and throughout the world, and, obviously, better for the United States."
