Snyder’s ambition is to persuade the West—and the rest of the world—to see the war in a broader perspective. He does so by disputing popular assumptions about victims, death tolls, and killing methods—of which more in a moment—but above all about dates and geography. The title of this book, Bloodlands, is not a metaphor. Snyder’s “bloodlands,” which others have called “borderlands,” run from Poznan in the West to Smolensk in the East, encompassing modern Poland, the Baltic states, Ukraine, Belarus, and the edge of western Russia (see map on page 10). This is the region that experienced not one but two—and sometimes three—wartime occupations. This is also the region that suffered the most casualties and endured the worst physical destruction.

More to the point, this is the region that experienced the worst of both Stalin’s and Hitler’s ideological madness.

Snyder claims that his purpose in describing 'all of the major killing policies in their common European historical setting' was 'to introduce to European history its central event'. But he has not described all the major killing policies and they did not all have a common setting. And to assert that they are the central event in the whole of European history is rhetorical overkill, to say the least. A number of other historians have written recently, and more perceptively, about this same topic, from Richard Overy in The Dictators to Robert Gellately in Lenin, Stalin and Hitler – some, like Norman Davies in Europe at War 1939-45, from a similar perspective to Snyder's own. Despite the widespread misapplication of Hitler's statement about the Armenians, few claims advanced in Snyder's book are less plausible nowadays than the assertion that 'beyond Poland, the extent of Polish suffering is underappreciated.' In fact, we know about the events Snyder describes already, despite his repeated assertions that we don't. What we need is not to be told yet again the facts about mass murder, but to understand why it took place and how people could carry it out, and in this task Snyder's book is of no use.

Mr Snyder’s book is revisionist history of the best kind: in spare, closely argued prose, with meticulous use of statistics, he makes the reader rethink some of the best-known episodes in Europe’s modern history.
