I would say it is true however. Following the colonial era in Africa (which incidentally was Africa's most prosperous & peaceful golden era), we have somewhere between 60-80 yrs or so of black leaders ruling in extravagant luxury & opulence in Africa, while they allow the genocide & destruction of their own country & people. Personally I can't think of a single black leader who has not raped & pillaged & plundered his own country while committing or allowing for unbelieveable atrocities, genocide & deliberate starvation of his own country.
President Mugabe perhaps is the poster child for black rulers, skimming off the foreign aid to his country, while decimating, destroying & killing his own people and destroying Zimbabwe, formerly Rhodesia which was the bread basket of Africa under white rule.
The apparatchiks and the commissars in DC are going to end up on the short end of the stick.
