For those who do not want competition but prepare interested in geopolitics like me, this book is a bible. A must have, with the Chauprade (oh the nasty fascist!) And the trilogy René Girault: European Diplomacy: Nations and Imperialism 1871-1914: Stories of Contemporary International Relations, Volume 1, Turbulente Europe and new worlds (1914-1941): History of Contemporary International Relations, Volume 2 and The Law of the giants, 1941-1964: History of Contemporary International Relations, III.
Enjoy reading!
