Strategic theories help leaders in the pursuit of their Countries’ aims, through the use of power, be it force or money, a tool so difficult to handle that — to quote a common say — one does not need an enemy to be defeated, he can do it alone! Regardless of what many writers say, the Western Countries are not at war. Their aim is to protect and, if possible, improve the quality of life of their people, by spreading peace, stability, and legality, to the benefit of all populations involved, and to withstand provocations with cool head and warm heart.This approach too requires support from strategic theory, to keep the coherence between aims and means: history tells, in fact, that those who lit the flames of war without limits ended badly bruised, when not burned by that fire.Strategy and Peace draws lessons from the past attempts, made during the XIX Century, to achieve similar aims, in order to suggest the ways to attain them, in our times.Ferdinando Sanfelice di Monteforte joined the Italian Navy in 1962.
