Admiral Mike Mullen, chairman of the U.S. military’s Joint Chiefs of Staff, told the CBS program "Face the Nation" that the air mission in the North African country has a clear, limited scope.
But Mullen said the end-game of military action in Libya was "very uncertain." Asked if it could end in a stalemate with Gaddafi, Mullen replied: "I don’t think that’s for me to answer. Certainly, I recognize that’s a possibility."
"It’s very uncertain on how this ends," he added.
