I first learned about geopolitics from Saul Cohen’s classic book, Geography and Politics in a World Divided. Cohen continues as the preeminent expert on geopolitics of our era. In this new edition of Geopolitics, he provides an unbiased and insightful overview of the world as it exists today, its axes of organization, and its tension points. The writing is clear and compelling as Cohen makes geopolitical theory accessible to all interested readers. Above all, Cohen reaffirms the overwhelming significance of a geographical perspective in understanding how the modern world operates and how it is likely to change in the future. All geographers, foreign area specialists, engaged citizens, and especially policy makers would do themselves an enormous favor by reading this book and absorbing its wisdom. 
David Kaplan, Kent State University Saul Cohen has put together a remarkable geopolitical tour du monde that will help readers appreciate the relevance of geography to international relations. Unlike some recent geopolitical accounts that represent geography as a static, largely physical set of influences, Cohen emphasizes the dynamic mixture of physical and human geographical elements that bear on the tumultuous geopolitical world we inhabit.  Avoiding jargon-laden prose, Cohen’s book is as accessible as it is wide-ranging. Its empirical detail will expand readers’ understanding of current events, and the author’s unabashed willingness to offer his own interpretations of the geographical circumstances that bear on those events will likely stimulate reflection and discussion.
