I am a liberal, by most accounts, and a peaceful one at that. I certainly did not approve of the war in Iraq, and in general, do not approve in violent actions. I have been split very much on these new sequences of events, however. The USA has a lot on it's plate right now and the last thing it needs to do is get caught up in unnecessary wars that purge billions of dollars into the military. We've been down that road already, for no apparent reason, we don't need to do it again.
Of course, there is a problem. The people of Libya were crying out for help. They reached out, in every channel that they had, and begged for help. Half of the country is controlled by people who desperately want change and are asking for help, asking for freedom. I don't think it's humanly possible to say 'No'. Can anyone, liberal or conservative, look me in the face and said, let these people suffer, our economy is more important? If so, then you should leave this country, because we asked others for our help in a revolution. When we wanted to rid ourselves of a monarchy, and barely had the means to do so, we reached out for assistance. I'm not going to go into depth, but check out the Wikipedia page for the American Revolutionary War: http://en.wikipedia.org/wiki/American_Revolutionary_War
We are not going in, full fledged, we are going in smart, precise, and as a team. This is not an effort for oil, or a past generational vendetta against a leader. This truly is to help a country in need, a people that desire their freedoms and a democratic government. I am not one for war, but I think the US and the UN in general, have done an excellent job in rising to a call for help.
Just as a side note, wouldn't it be funny, or ironic moreso, if in the future Libya helped America in their time of need...
