Apart from praising Nelson Mandela, US president-elect Donald Trump hasn't had many nice things to say about Africa. He reckons South Africa is a "crime-ridden mess" and one of its judges is a "moron".When Nelson Mandela died in 2013, Trump took to Instagram to say: "Nelson Mandela and myself had a wonderful relationship - he was a special man and will be missed."Later he said: "I really like Nelson Mandela but South Africa is a crime-ridden mess that is just waiting to explode - not a good situation for the people!" He also opined: "As I have long been saying, South Africa is a total - and very dangerous - mess. Just watch the evening news (when not talking weather)."And Trump was not impressed with Pretoria High Court Judge Thokozile Masipa after she acquitted Oscar Pistorius of murdering his girlfriend, Reeva Steenkamp."The judge in the Oscar Pistorius case is a total moron. She said he didn't act like a killer. This is another OJ disaster!" Following former President Barack Obama's pledge of $7-billion to support the building of reliable electric power grids in sub-Saharan Africa, Trump tweeted: "Every penny of the $7-billion going to Africa as per Obama will be stolen - corruption is rampant!"He also thinks African leaders, and those in the opposition parties, are greedy."Look at African countries like Nigeria or Kenya, for instance, those people are stealing from their government and go to invest the money in foreign countries. From the government to the opposition, they only qualify to be used as a case study whenever bad examples are required."..
