"However, those European countries haven’t acknowledged or apologized for what they have done."

Not completely and not for everything, but largely it is at least recognized. I mean, I learned about it and how bad it all was in a ordinary european school. What you say implies it is like in turkey, where they don't tell students in school what happened in Armenia. Or like in china, where even the knowledge gets removed. (I think Japan also largely choose not to reevaluate its glorious bloody empire past)

So blaming every war in Africa on the colonial past is maybe not helpful, when there have been wars before european involvement. And especially here, to me it seems a inner muslim/arab war. Different factions backed by different arabic states. UAE and Quatar. What exactly is the european involvment here?
