On the world map, many areas of instability can be highlighted, along with the identification of conventional and non-conventional threats in many fields, such as energy, environment, migration, financial and food sectors, meaning that the international scenario increasingly and rapidly changes under new emerging factors and needs. The rapid evolution of problems and problematic situations calls for reactive and continuously updated tools of response. A prompt reaction can be structured through global analysis and commitment, to be achieved in the framework of trans-national responses and plans. In fact, policies based on the principles and values of democracy can help towards these objectives. To summarize, it is possible to envisage some possible tools, such as: multilevel vision and coordination, proactive coordinated approach, complementarity, development of threat management and a multidimensional approach.
