Book excerpt: This publication shows that the Eastern Mediterranean, having been transformed from a region of secondary importance during the Cold War to one of greater importance for the western interests in the post-Cold War era, is in a state of flux. Despite sporadic periods of rapprochement, tensions between Greece and Turkey still exist. Therefore, one must question the grounds behind the lack of normal relations that exist between these two NATO members and its effects on the NATO organisation as a whole. Hence, this volume has two purposes first, to examine Greek and Turkish foreign, security and defence policies during and after the post-Cold War period and second, to investigate why these policies have been formulated.
