The UN is a committee body that only works as long as people agree to abide by the rules they all agree upon.
Muammer Gaddafi is killing his own people. He has openly denied that there is any kind of resistance to his leadership when we all knew there was. And now that he absolutely refuses to give up power, he is killing Libyan citizens. He cannot be allowed to get away with what he is doing. An intervention was necessary and I'm personally disappointed that Australia didn't offer some kind of military involvement.
I do agree with you, emotionally, I really do. However, if every self-proclaimed world power were forced to step in every time someone in another country does something they don't agree with, there must come a time when the line is drawn in the sand.
At what point exactly are we crossing the border from what is and is not our business? Or, to put the question in a more forgiving tone, at what point does the dealings of other nations become something that has nothing to do with us, and where we have no place sticking our noses in and telling everyone what they are and are not allowed to do?
No one currently assaulting Libya has any sovereignty over the nation, no real legitimate right to step in and take control. I agree that something should be done, especially since both sides have refused to cooperate with international sanctions as well as a complete refusal for a peaceful resolution, but if they are so damn intent on fighting to the bitter end, perhaps it would just be best to allow them to do so by their own will. I certainly never asked them to flare up a war off the cuff, and I don't see it as my personal responsibility to clean up a mess that they themselves chose to start.
As for Gadhafi, he's more along the lines of Castro and Kim Jong Il than Hitler. It isn't like he's leveling cities and committing mass-genocide over there. He isn't being gracious about it, I'll admit, but he's just trying to shut down a rebellion he sees as a threat to his country, regardless of his legitimacy to rule.
