The complex and fluid nature of asymmetry is analyzed and then the sources of changes in conflict asymmetry are discussed. This analysis is then applied to particular conflicts that have followed different trajectories of asymmetry and conflict transformation. The trajectories include (1) transformation toward symmetry and equitable resolution (South Africa and the civil rights struggle in the US South) and (2) protracted failure to achieve appropriate symmetry or to have unilateral imposition (Sri Lanka, Palestinians and Israelis).
