World War II is the good war, the one where evil was defeated. But there was always a rub. The great ally of England and America was not a democracy. It was a totalitarian power. And it did the heavy lifting, which is to say that Stalin's Red Army carved up the German Wehrmacht. It engaged, at a horrific cost, in the big battles that settled the course of the war that Stalin's original gamble—conniving with Hitler and his henchmen to conquer and divide Poland, the western Ukraine and the Baltic States in 1939—had helped bring about. It was the Red Army, in short, not the American or British one, that fought the battle of Berlin in the spring of 1945 to liberate the German capital from the Nazis, a pivotal moment closely covered by Michael Dobbs in his forthcoming book Six Months In 1945.
