ABSTRACT
Linking IR theory to evidence has always been challenging, as Hermann (2002) correctly observed. All the more so in the digital age, we would add. In this concluding chapter, by drawing on the previous case studies and theoretical elaborations, we will suggest a few synthesizing observations and propositions on how the information revolution impacts on the security of states and societies. These can be seen as contributions to theory building which take into account the implications of the digital age. Second, we will discuss how existing IR theories fared in the empirical applications. Finally, we will comment on some specific requirements for further theory building on digital-age security.
