Is Geopolitics Still Relevant? Halford Mackinder and the War in Ukraine

Abstract

This paper starts with an assumption that geopolitics, understood as one of the great schools of international relations, is not only still relevant but, indeed, should be one of the essential items in the toolkit of any student or policymaker who peruses the challenging and ever-eluding realm of international security. It draws chiefly on Sir Halford Mackinder's Heartland theory in order to explain the dynamics of contemporary European security in general, and the ongoing war in Ukraine in particular. The analysis, which relies heavily on a historical examination of the geopolitical realities of Central and Eastern Europe, leads the author to a pair of conclusions. Firstly, the conflict in Ukraine is likely to linger on albeit with unpredictable intensity and, secondly perhaps more importantly, the outcome of the war will only be one of many steps leading to the emergence of a new, possibly multipolar, international system and consequently, and more obviously, a new security system in Europe, which will be strongly influenced by Germany rather than by the United States as before.
