Adm. Mike Mullen, chairman of the Joint Chiefs of Staffs, described the campaign’s aims as “limited,” saying it “isn’t about seeing him (Gadhafi) go.” Appearing on NBC’s “Meet the Press,” Mullen was asked whether it was possible that the mission’s goals could be achieved while leaving Gadhafi in power.

“That’s certainly potentially one outcome,” he replied.

Pressed on this point later in an interview on CNN’s “State of the Union,” Mullen was more vague. “How this ends from the political standpoint, I just can’t say,” Mullen said. He said it was too early to speculate.
