It’s a mistake to attribute Lumumba’s assassination entirely on the CIA. Belgians were heavily involved, likely including the murderers themselves. This is why the Belgian government apologized for its country’s role in his death. This apology came shortly after a movie about his was released (terrific, I might add). Also, the Congo is a mess only in part because of US intervention. (The Rwandan genocide, by contrast, is largely attributable to Belgium, which instituted a rift between Hutus and Tutsis, and giving them identification cards of different colors.)
