Libya part 2

So the shit has finally hit the proverbial fan in Libya. The US, France, British, and UN forces have been bombing Gaffafi's forces in Libya however the mission now seems unclear. Are they just trying to enforce the no fly zone and prevent violence against civilians as they say? Or are they forcibly trying to remove Gaddafi from power to establish a new regime a la Iraq. Alot of Obama's liberal base are criticizing the decision but I feel it was the right thing to do. It seems that Hillary and him were butting heads on the issue with her pressing for US support and him being reluctant to participate. I hope the violence ends soon.
