Here is what he said.

'You know I am not very happy with Nigeria. I have made that very clear on many occasions'. Yes, Nigeria stood by us more than any nation, but you let yourselves down and Africa and the black race very badly.

 Your country used to be respected. After your suspension from the Commonwealth, many western countries approached me to help in isolating Nigeria so that it will be easier to bring down your military dictators. I consulted many African leaders, and all were unanimous in their advice. They told me to stay clear of Nigeria. That you will fix your problems. You have done it before. ‘But, you have not. Not this time'. The world will not respect Africa until Nigeria earns that respect. The black people of the world need Nigeria to be great as a source of pride and confidence. Nigerians love freedom and hate oppression. Why do you do it to yourselves?

"Your leaders have no respect for their people. They believe that their personal interests are the interests of the people. They take people's resources and turn them into personal wealth. There is a level of poverty in Nigeria that should be unacceptable. I cannot understand.

Let me tell you what I think you need to do' he said. 'You should encourage leaders to emerge who will not confuse public office with sources of making personal wealth. Corrupt people do not make good leaders. Then you have to spend a lot of your resources for education. Educate children of the poor, so that they can get out of poverty. Poverty does not breed confidence. Only confident people can bring changes. Poor, uneducated people can also bring change, but it will be hijacked by the educated and the wealthy'.

give young Nigerians good education. Teach them the value of hard work and sacrifice, and discourage them from crimes which are destroying your image as a good people.'

many year's later Nigeria is still battling with all Mandela said. It's really sad.
