Going forward, what role does the U.S. have in Libya?

Moammar Gadhafi's four-decade-long rule over Libya is crumbling as hundreds of rebel fighters move towards the heart of Tripoli and secure control of parts of the capital.

The U.S. State Department reportedly had officials in Benghazi this weekend to talk to rebel leadership about how the country will proceed if Gadhafi is effectively overthrown.

Hisham Melhem, Washington bureau chief for Al-Arabiya Television, discusses what steps the United States is expected to take in establishing relations with a post-Gadhafi Libya.
