Seretse Khama: His legacy remembered

The fairest judgement of the performance of the past presidents of Botswana would only be possible when it is measured against what is now popularly termed the millenium goals.

 
You might say those are universal measurements of performance relating to a long, quality life for citizens, child morbidity, safe motherhood, active political decision-making and access to developments in science and technology.
One would also have to refer to indicators such as access to justice, freedom of expression, control of corruption, institutions that ensure openness and transparency and fair gender relations that place children first.
