When Mugabe stood between Botswana, Namibia

Does anyone recognise the big role President Robert Gabriel Mugabe of Zimbabwe played as mediator when Botswana and Namibia nearly went to war in the 1990s over a seemingly insignificant piece of island in the Chobe River called Sedudu?

The island, which is five square kilometres, is situated in the middle of the mighty Chobe River on the western side of Kasane. There are times when it is submerged in water and others when the waters subside.
