The war trade. The ways of making wars are changing. Together with the classical armies, new private military companies, paramilitary people, men of war and mercenary people´s armies are emerging as new characters of the war. Nowadays, the wars are less common between States and tend to take place inside those States between regular and irregular troops and; in all cases, against the civil population. In too many places, the war has become a real business; another management product whose profits can be valued in million thousand dollars and apart from that, there are other aims .Instead of fighting for places which are geographically strategic, they compete for the humanitarian help management, natural resources or the narcotic trade control. This book; which has been translated into different languages and modernized after its first edition, gathers all those subjects by means of that research and analysis carried out by great specialists.
