So who/what is going to replace this half-baked idiot Gadhaffi?
Al Qaeda has influence among the people there.
That, of course, is the $64,000 question. If we do nothing, then Gaddaffi will crush the uprising, killing lots of people in the process. If we intervene, then Al-Qaeda or Al-Qaeda aligned powers may take over. OTOH, if we intervene we might be able to influence who takes over. We may be able to oust Gaddaffi and cut out Al-Qaeda as well.
