A book written by Tim Marshall, the subtitle is "Ten maps that tell you everything you need to know about global politics." This is a book about geopolitics. The back cover explains "All leaders are constrained by geography. Their choices are limited by mountains, rivers, seas and concrete. Yes, to follow world events you need to understand people, ideas and movements - but if you don't know geography, you'll never have the full picture. ....... If you've ever wondered why Putin is so obsessed with Crimea, why the USA was destined to become a global superpower, or why China's power base continues to expand ever outwards, the answers are all here."
