In recent years the distribution of the world's exploitable energy reserves has shifted markedly. One major change is the discovery of substantial gas deposits offshore the Levant. But while these deposits have the potential to revolutionize the economies of the net energy importers, Cyprus, Lebanon, and Israel, they also bring into sharp focus long-running disputes over maritime boundaries and sovereignty. In short, these deposits provide yet another cause for conflict in an already deeply troubled region. This monograph explores both the positive and negative implications of the Eastern Mediterranean's new gas reserves for the region, and the implications of both for U.S. interests. It combines the recognized expertise of two researchers with long experience in regional and energy studies, respectively.
