Our heroes today(Nelson Mandela and Chinua Achebe)

Late Nelson Mandel, during his twenty seven years of imprisonment the late South African President reports that "There was a writer named Chinua Achebe in whose company the prison walls came down...He was the writer who brought Africa to the world"
Do you think we Africans we ever have a leader like Nelson Mandiba Mandela and Professor Chinua Achebe?
