The Arab League wanted a No-Fly Zone. They even volunteered some of their own fighter aircraft to enforce it.
However, the Arab League wanted the No-Fly Zone Fairy to wave her magic wand so that their aircraft could safely fly, back and forth, in the Libyan sky, with the Libyan air defenses still intact.
Unfortunately, there is no such thing as a No-Fly Zone Fairy. The sky is safe only after a swarm of cruise missiles followed by a swarm of manned aircraft with HARM missiles blow up every anti-aircraft defense radar station to Kingdom Come.
So, in fact, the Arab League is criticizing the U.S. for making it safe for Arab League fighter aircraft to do what they wanted to do.
Facetiously, what the U.S. could have done is to say, "Fine. A No-Fly Zone has been declared. Send in your aircraft to enforce it, Arab League. Once a dozen Arab League aircraft are blasted out of the sky by Libyan SAM's and the Arab League begs the U.S. to take out the Libyan air defenses, then the campaign to suppress Libyan air defense can proceeded."
Realistically, what the U.S. could have done is to have a President that paid more attention to his job than to NCAA basketball brackets so that all of this would have been discussed and settled before the first Tomahawk was ever launched.
