Former Arkansas Gov. Mike Huckabee says a no-fly zone would be "very important because that way you keep (Gadhafi) from flying mercenaries in." He would also position a naval armada off the Libyan coast.
Anthony Cordesman, a national security analyst at the Center for Strategic and International Studies said much of the talk of a no-fly zone seems divorced from the reality of what's actually happening on the ground.
There is scant evidence that Gadhafi's fixed-wing aircraft are doing much military damage, tracking attack helicopters "requires you to maintain a constant presence" and most of the battle is ground action that "would not really even be affected by a no-fly zone," said Cordesman, a former director of intelligence assessment at the Pentagon.
