Those who are against the UN intervention seem to forget that the revolt began as a peaceful protest in which unarmed civilians were set upon and murdered by Gaddafi's goons and helicopter gunships and were forced to take up arms in self defense. Once that die was cast there was no turning back as large numbers of civilians would have been butchered by the tyrant. As it stands he has lost all legitimacy as the leader of Libya, in the eyes of the world and the International Criminal Court which will likely issue a warrant for his arrest by the end of the month. This will effectively make it impossible for him to escape into exile, thus sealing his fate.
