This thesis examines the connection between geopolitics and the images of threat of cyber war as presented in the national security and cyber security policies of four member states of the European Union and NATO: The Netherlands, France, Latvia and Lithuania. Using securitization theory the policies are examined for references to overarching national security threats in the presentation of cyber war as an existential threat to the state. The study finds a difference between the western and eastern EU and NATO states regarding the use of geopolitical arguments of securitization, with the eastern countries displaying a clearer tendency to connect the threat of cyber war to geopolitical factors. On the basis of these findings, the author argues for the need of reconceptualization of some concepts central to the field of international relations as cyber security becomes and ever more important factor of security to states and non-state actors alike.
