Deciphering post revolutionary Iran’s state behaviour is difficult. Based on a theoretical foundation, the book dissects Iran’s state behaviour. Narrowing it down to issue area approach, it lays emphasis on the discourse of state behaviour and how it negotiates and re-negotiates with different actors and circumstances alike. Factored in the pre-conceived notion of differentiation between foreign policy and state behaviour, this book examines the overlapping character of the two, its tendency to merge in a low and high intensity scenario; nonetheless posturing it differently at a different point of time. This is done by taking the case study of Islamic Republic of Iran with reference to four issues, political Islam, energy, nuclear ambition and regional engagements.
