Abstract: This paper aims to set out a framework for the analysis of national security strategies.
This will be achieved in three steps. First of all, I will define what national security means. In so doing, I will go through the definitions and redefinitions of the concept of national security has provided by scholars so far. I will identify the pros and cons of the “narrow” and the “wider” agenda of national security. Then, I will seek to compromise both approaches into a new definition of national security. Secondly, I will analyze the threats that can put at stake national security. I will proceed by dividing national security into conceptual spheres of security. This reduction will help us to analyze threats in three specific sub-security sectors: the politico-military security, the economic security and the energy security. Subsequently, I will reassemble the sectors in order to recompose the unity of national security. Thus, I will underline how this process points out areas of inter-sectoral connections between sectors. Finally, I will identify what are the variables that generate different security strategies. In this regards, I will focus on two set of variables: external and internal to the state. The former concerns the “system” in which the state acts, while the latter, instead, is about a state’s domestic qualities, such as socio-political strength and strategic culture. The different combination of this set of variables will explain why different states adopt different security strategies.
