I don't know about that, but you don't have to listen long to Mugabe to realize that he is himself a rather sad ironic victim of imperialism, making the experience of imperialism into a sort of theory of everything when talking about Africa.
Theories that try to encompass too much are always wrong, it reminds me of fundamentalist readings of Marx, just like the means of production are not the tealeaves in which you can find an explanation for any eventuality, neither is imperialism, but it is a defining feature of modern African history.
