My take on the matter is that Mugabe has long overstayed his welcome. He somewhat rides the tiger, if he falls off the Tiger eats him. He can't release the vote totals, they are so one sided against him, even he can't figure out how to fudge them. Now he probably awaits some exile deal except he is so senile by now, he is just in it for then power he will not give up. Its been about personal power for so long, he has long forgotten the day when he actually had any any goals of making things better for anyone else but himself.
Its hard to have the hate to wish someone was dead, but the world would be a far better place if he were right now. Either natural causes or a 25 cent bullet. Exile would be acceptable also. Zimbabwe is the thing worth saving and it can't even start to heal until Mugabe is gone.
