Illinois U.S. Sen. Mark Kirk says he thinks Libyan leader Moammar Gadhafi doesn't have much time left in power.
The United Nations voted to authorize a no-fly zone over the country. Libya's foreign minister then declared a cease-fire against rebel forces, although there have been reports that the cease-fire isn't being obeyed.
Kirk said NATO forces are now talking about taking military action.
"The Gadhafi dictatorship is now, I think, terminal," Kirk said. "If the rebels are allowed to consolidate a government and then begin to attract people to Benghazi, I don't think the Gadhafi dictatorship can last for long."
Kirk said he would like to see the rebel government defend Benghazi, which he says would be politically fatal to Gadhafi.
