This book investigates the enduring relevance of Halford Mackinder’s Heartland theory in the context of modern Western defense and global power dynamics. Brian Blouet, a scholar of geography and geopolitics, utilizes historical analysis and Mackinder’s original writings to argue that the geographic pivot of history remains a critical factor in understanding contemporary international security. The work provides a framework for evaluating how shifting land-based and sea-based power structures influence the stability of the Western alliance.
