Don't we want to know who the rebels really are? The argument continues to be "we don't know who these people are? Are they Libyan nationals or are they remnants of Al-Quaida mixing in with the fighters? We just don't know." Well, with CIA boots on the ground, we should know rather quickly exactly who we're dealing with among the rebels - friend or foe.
More to the point: You're either going to believe what "their" media and/or people are telling us OR you're going to believe what OUR operatives feedback what they learn from their intelligence gathering.
