1. Introduction
There is conflict and violence in the present world. Immediate examples that come to mind are the current situations in Iraq, Palestine and in the south of Thailand. What we wish to see is solutions to these those problems by peaceful methods, for instance negotiation and mediation, but, even though, sometimes, some groups might attempt to use such methods, in the end: conflict and violence still remain a constant. It is as though neither conflict nor violence will ever die out in human beings or societies.
