Struggle over the river of the Nile has had a long history.Egypt’s claim to veto over the projects of the upper riparian countries and the demands of the latter to use the water of the Nile has caused continual conflicts of interest in the Nile Basin. This book has explored both past and the present struggle to use and/control the water of the river Nile. Egypt, backed by its dependency on the Nile water, the 1929 and 1959 agreements, and its military might has been a major user and defender of the Nile water; excluding the upper riparian countries. This book has answered its main question of whether the competing claims to use the Nile water would lead the region into water war, conflict or cooperation, or the co-existence of conflict and cooperation in the Nile Scenario. The question of War or Peaceful cooperation was analyzed through the contrasting theoretical frameworks of international relation theories of realism and liberalism. The findings, presented in short in this chapter, are structured around a number of points pertaining to water war,conflict or cooperation, and conflict-cooperation nexus.
