How do we look at foreign policy and how current are its frameworks and levels of analysis today? In response to this question, the various authors in this book have amply demonstrated how interest in foreign policy has greatly increased in recent years, both in terms of the research devoted to it and in terms of the covetousness with which it is viewed by actors of all kinds. The new postures and perceptions of the State, as well as the way it is viewed by other social actors, are part of the changes that can be observed in foreign policy and present a serious challenge to the original conception of the State as the keystone and raison d’être of foreign policy.
