It’s actually impressive to me how the West and its satellites are able to so impressively compartmentalize their propagandistic narratives in the service of war and imperialism, even digging up shit like this when “hindsight” is supposed to be a thing. It’s not like this ended in any case. They will support Chechen freedom fighters against RuZZian orcs one day while also emphasizing Israel as a bulwark against radical Islamic hordes the next.
Africa falls behind because the capital and the resources that would develop their industries and productive forces is being stolen through violence, and because they got repeatedly sabotaged and politically debilitaded.
Your way of putting the situation obscures the exploitative and violent nature of imperialism and places the blame on the country getting pillaged, as if they just can't figure out how to use their own resources or govern themselves.
