[Watch] Obama tells Leno, ‘Libya a recipe for success’

Laying out an argument for his emerging foreign policy doctrine, Obama distinguished the U.S. steps in Libya from the invasion and nine-year war in Iraq. He argued that by building a broad international alliance of European and Arab nations against Gadhafi, the United States saved American lives and money and achieved its goal.

"Not a single U.S. troop was on the ground," he said. "Not a single U.S. troop was killed or injured, and that, I think, is a recipe for success in the future."

Nudged by Leno in a notably sober first segment, Obama reflected on the meaning of Gaddafi's death, a gruesome and chaotic demise recorded on cellphone video for all the world to see. The president argued that Gaddafi had had an opportunity to let Libya move on a path toward democracy peacefully.

"He wouldn't do it," Obama said. "And, obviously, you never like to see anybody come to the kind of end that he did, but I think it obviously sends a strong message around the world to dictators that people long to be free, and they need to respect the human rights and the universal aspirations of people."

Still, Obama noted that the Pentagon never released photographs of terror mastermind Osama bin Laden after he was killed by U.S. Navy SEALs.

"That's not something that I think we should relish," the President said. "You know, I think that there's a certain decorum with which you treat the dead even if it's somebody who has done terrible things."

Obama's appearance on the Leno program, taped extra early at NBC studios to satisfy his schedule, is his fourth on the show and his second as president. The appearance came in the middle of a lucrative three-day fundraising tour for the president even as he tries to bring attention to the plight of people suffering in a weak economy.

The interview covered a range of topics, from foreign policy to Obama's jobs bill to television watching. The first segment, free of jokes or chitchat, focused on Libya, Iraq and al-Qaida.

Obama announced last week that U.S. troops would leave Iraq by the end of the year, effectively ending the war that began under the administration of President George W. Bush and that Obama ran against as a candidate in 2008. Asked by Leno what the United States accomplished there, Obama conceded that Saddam Hussein was gone and that Iraqis now have an opportunity to create their own democracy. He said he was "cautiously optimistic" that they would resolve their conflicts with discussion and debate, not violence.
