An effective essay that deals quickly and comprehensibly with a complex subject. The author has sought to show an "insider's" view, which gives the work an honesty that is difficult to find in the world of power and politics. The book aims to inform the general public and, at the same time, to interest professors and researchers of Constitutional Law so that they can tackle with academic rigour several of the issues that are addressed, since, despite the importance of the military institution in ensuring the survival of the State, not many in-depth studies have been carried out in Hispanic culture on both sides of the Atlantic.
