The Revenge of Geography: What the Map Tells Us About Coming Conflicts and the Battle Against Fate

Kaplan argues that geography—terrain, climate, proximity—remains the most enduring constraint on what any state can achieve, and that the post-Cold War belief in a 'flat,' borderless world was an optimism Iraq exposed. He rejects the assumption that globalization, technology, and liberal universalism have rendered physical geography irrelevant. Drawing on Thucydides and Hans Morgenthau, he contends that while human agency matters, it operates within limits dictated by the map. The book positions itself as a corrective to 'end of history' thinking and the 'geo-economics' school .

Kaplan resurrects classical geopolitics, a body of thought Western academia set aside after 1945 due to its association with Nazi Lebensraum theory. The key figures are Halford Mackinder, whose Heartland thesis identified the Eurasian interior as the pivot of world power; Nicholas Spykman, who countered that the Rimland—the coastal crescent—held the key; and Alfred Thayer Mahan, who argued maritime power determined global dominance . Kaplan's contribution is synthesis and application, not new theory. He explicitly distinguishes classical geopolitics from its Nazi distortion .

Both books treat geographic and environmental factors as fundamental shapers of human history, but they operate at different scales and with different purposes. Diamond's work is macro-historical and explanatory, asking why some societies developed differently over millennia. Kaplan's is contemporary and prescriptive, asking how geography constrains great-power competition in the twenty-first century. Reviewers have noted the affinity: Anne-Marie Slaughter described Kaplan's approach as telling the same kind of story Diamond tells, with geography and climate shaping the more variable element of human choice . The comparison is useful but imperfect; Diamond is a scientist, Kaplan a journalist-strategist.

The dominant criticism is that Kaplan is a geographic determinist—that he overstates the role of terrain and understates contingency, institutions, and human agency. Critics including geographer Harm de Blij argued that Kaplan's book misrepresents geography as a discipline . Kaplan anticipates this charge and retreats to what he calls 'partial determinism': geography is an indispensable 'backdrop' to the drama of ideas and will, not a script that dictates outcomes . His formulation—'the map, though not determinative, is the beginning of discerning a historical logic'—is an attempt to occupy the middle ground between determinism and pure contingency .

Kaplan's diagnosis of geography's enduring relevance has aged better than some specific predictions. His forecast that the Mediterranean would 'become a connector' rather than a divide, powered by offshore energy, has seen partial validation . His reading of Russia as lacking an uplifting ideology beyond geography, and therefore structurally tense with China, remains analytically useful. His prediction that China would shift from land-border resolution to maritime assertiveness—'project hard power primarily through its navy'—has proven prescient . Where the book has aged less well is in its relative neglect of domestic political factors and technological change in shaping state behavior.

Many readers assume the title signals full geographic determinism—that Kaplan believes the map dictates everything. In fact, Kaplan explicitly rejects that reading. He calls for 'the partial determinism we all need,' positioning geography as a necessary but insufficient condition for understanding outcomes . The confusion is understandable: the book's structure, which begins each chapter with a reading of territorial lineaments, creates a determinist impression. But Kaplan's analytical practice is more nuanced. He treats geography as the baseline from which other factors—culture, demography, leadership—operate, not as a substitute for them .
