I'm in the "Kony 2012" movement. So, obviously, I disagree with you...
IMHO, developed countries should occupy Africa in order to fix all the atrocities we (developed countries) have caused. Our moral obligation is to help Africans building a fair future... The only way I see to do that is ending up with dictatorial systems and building real democracies around there (but, obviously, the first thing to do is stopping hunger).
Occupation has became a system used by countries like the USA or even Spain to do whatever's good for them... But occupation can also be used to help underdeveloped countries, to improve people's life. Spain was better with José Bonaparte than with Carlos IV, that for sure (and our "Constitución de Cádiz" would not have been possible if Carlos IV had never been attacked by Napoleon troops)
