A frustrated Archbishop Desmond Tutu is challenging South Africa to stand up to Zimbabwe President Robert Mugabe, according to ABC. Tutu, who says South Africa has betrayed its legacy, suggests that the nation use force to remove Mugabe from office in order to improve an otherwise flawed government. South Africa has refused assistance from the United Nations to rectify the problems in Zimbabwe. British Foreign Secretary David Miliband, along with Archbishop Tutu, believes that Mugabe is a “stain” to the country and the world.
