Yet for nearly a third of the conflict's entire timespan, Hitler and Stalin stood side by side as partners. The Pact that they agreed had a profound and bloody impact on Europe, and is fundamental to understanding the development and denouement of the war. The Devils' Alliance explores the causes and implications of the Nazi-Soviet Pact, whose creation and dissolution were crucial turning points in World War II. Forged by Joachim von Ribbentrop, and his Soviet counterpart, Vyacheslav Molotov, the nonaggression treaty briefly united the two powers in a brutally efficient collaboration. The Germans and Soviets quickly conquered and divided central and eastern Europe. Hundreds of thousands of people caught between Hitler and Stalin were expropriated, deported, or killed. Fortunately for the Allies, the partnership ultimately soured. Ironically, however, the powers' exchange of material, blueprints, and technological expertise during the period of the Pact made possible a far more bloody and protracted war than would have otherwise been conceivable. Combining comprehensive research with a gripping narrative, The Devils' Alliance is the authoritative history of the Nazi-Soviet Pact.
