I've been pretty fascinated by that too. I'm not a big theory reader outside of a little Marx and shit, but I heard enough interesting stuff about Frantz Fanon's writing to draw me to his book Wretched of the Earth, and had this to say in his preface for European readers:

But, you will say, we live in the mother country, and we disapprove of her excesses. It is true, you are not settlers, but you are no better. For the pioneers belonged to you; you sent them overseas, and it was you they enriched. You warned them that if they shed too much blood you would disown them, or say you did, in something of the same way as any state maintains abroad a mob of agitators, agents provocateurs and spies whom it disowns when they are caught. You, who are so liberal and so humane, who have such an exaggerated adoration of culture that it verges on affectation, you pretend to forget that you own colonies and that in them men are massacred in your name. Fanon reveals to his comrades above all to some of them who are rather too Westernized — the solidarity of the people of the mother country and of their representatives in the colonies.
