The nature of conflict around the world has changed since the end of World War II. Since that time, there has been an increase in the number of intrastate conflicts, and these conflicts have become more violent and deadly. Since many of them involve questions of identity, the traditional methods of conflict resolution typically cannot be applied. Many intrastate conflicts also involve third-party interventions which add another dimension to the conflict. This paper will address the changing nature of conflict and the rise of intrastate conflict and resolution by including explorations and analysis of the conflicts in Rwanda and the former Yugoslavia in the early 1990s. The analysis of these conflicts (including third-party interventions) will point to the potential importance of mediation as a form of conflict resolution in identity conflicts which involve ethnic tensions. Finally, this paper will end with a discussion of the current conflict in Libya and an assessment of third-party interventions to date as well as things to consider in searching for a resolution to the conflict.
