I, who was looking for a book in a few chapters summarizing international relationships with major conflicts, I was served. Very pleasant to read, with a summary at the end of each chapter, this is the perfect book to understand a little better geopolitics and its evolution until our era of the 21st century. I chose the Pascal Boniface book, despite the multitude of books on the subject, the author appear to myself as trustworthy as to his intellectual honesty.
