world leader?

to me this depends on how we see the term world leader, the term to me can be used to mean a single person to lead the whole world, like a one world nation leader. in this case i feel that the best person for the job would be Nelson Mandela. We only need to look at what happened in south africa after the end of apartheid any other leader would have caused a blood bath when the majority blacks gained power, instead mandela lead the coulntry to a more peaceful future with little white blood spilt. Therefore imagine Mandela being the leader of the whole world and what he would bring to world conflict, there would certainly be less bloodshed.
