Southern Sudan is just the beginning. The world may soon have 300 independent, sovereign nations ... and that's just fine.
Whether or not Yemen, Iraq, Pakistan, or the Democratic Republic of the Congo technically qualify as "failed states," their fates are sealed by their colonial inheritance. Indeed, it's often their borders that are the deepest cause of their conflicts.
