In this project, lasting 14 months, IAI acts as project leader. The study intends to provide a comparative analysis of the EU-US relationship with regard, in particular, to the definition of the security strategies of both actors, the evolution of their internal security, the security industry in the transatlantic context and the different approaches and perspectives of the respective transatlantic policies. The project includes two series of workshops to be held in Rome, Washington, Paris and Stockholm which involve both researchers of the four partner institutes and external experts.
