When Nelson Mandela decided to step down after only one term as president of his country, he created one of the world's most exclusive and tiniest clubs.
Almost nowhere do political leaders decide they are so easily dispensable.
In the rich world, most have to be defeated, or see humiliating defeat looming before retiring. In Africa, most leaders have had to be carried out in body bags, their bodies often weighed down with lead.
In this matter, as in so many others, "Madiba" was unique and set a glorious example, which the leaders who now honour him so piously have not the slightest intention of following.
But just being Mandela didn't always make him right.
