He is one guy at the end of life, past any strength. He did his good and had his day. My guess is that in the current situation in South Africa, you wouldn't be able to say anything about Zimbabwe without large consequence for those around you. Whoever his spirtual successor is, the person who can defend his allies and interests should there be political reprisals, that's the person who needs to speak. In fact, many, many other people need to speak and act. What was the story about the union that turned a shipful of small arms due for Zimbabwe back? There needs to be a lot more of that.
