Having a strategy means finding solutions to the complexity of the global world. The task of this manual is pointing out a possible method to transform the future to our advantage and seize also economic and financial opportunities crucial to emerge in the global competition. The book provides an analysis of the evolution of strategic thought and method, from the dawn of nation-states until the civil war in Syria. What happens in this country is emblematic of the change in perspective and power in recent years. With the “preventive war” the West had come to the borders of India, but today we see the Chinese military presence in the Mediterranean. The structure of global power is increasingly oligarchic, Asian and present in a wider area. A triad that bears the names of the US, Russia and China. Europe is witnessing an inert vacuum created in the South, across the Mediterranean and North Africa. The old continent is in decline, and doesn’t have a real strategy.
