There's no anarchy in Haiti, there's just a bunch of factions trying to win the upper hand either by force or by deception. It's become like a little scale model of the Earth.
Also it's funny how all discussions that include something about anarchy end up being "people are to silly to run themselves, that's why we need governments sprinkled withn soldiers to protect them from themselves". "I, Robot" rigs a bell?
If most people are too idiotic to run themselves, by extension the authorities are also idiots without the capability to govern themselves, let alone others.
But it's a fact people are not too idiotic, just most are too uneducated and live within too precarious material conditions to allow a proper development.
