Key difference is Bush went against UN decisions and went to Iraq anyways.
Regardless, this time US is truly in a Catch 22. If they leave Libya, they'll be called out for: a) Leaving innocent people under a tyrannical regime or b) Putting oil in front of people's lives. However if they do topple Gaddafi's regime, they will most likely have to occupy the territory to prevent a civil war, which leads to accusations of another Iraq clusterfuck.
Leave Libya alone, get called soulless corporate monsters, intervene and get called imperialists extending their power to countries that can't fight back. The only way I see the US getting out of this is to get UN Peacekeepers instead of any actual army personnel. I just hope the US gov't doesn't someone fuck this one up.
The thing is though, Libya has no strategic value to the U.S, and Libya only produces 2% of the world's oil ( Saudi Arabia is going to produce that much more in wake of the war), so really, what the hell are we doing there?
I use to think it was for the safety of the Libyan people, but knowing that the rebels have ties with terrorism, What's the point?
Obama said it is to stop a massacre, but if the main goal is not to remove Qaddafi as he has said, WHAT'S THE POINT? Also, if it's to stop a massacre, why aren't we establishing no-fly zones over Syria? Yemen? or any of the other countries that are killing there own people? Why only Libya?
Obama has said that this is not another Iraq, but look at the facts; We're going in without a main objective, without an exit strategy, no timetable, aiding a questionable rebel force that we have no idea who is in charge or who is backing them, and we went in with no congressional approval (I could not give a fuck if he went in with UN approval). Some democrat & republican senators are even thinking about impeachment because of this. (Highly doubt if it will ever get that far though).
After listening to the President, I honestly think he has no clue what to do. He has no idea, which is scarier than anything.
