World War II in Europe is largely considered the worst war ever waged on Earth by the Western Alliance. The National Socialist government of Germany waged a war for power and genetic purity. Over five million Jews, twenty five million Slavs, and as many as ten million Germans died in the resulting holocausts. Poland, Russia, and Germany were hardest hit, with between ten and twenty percent of their total population killed before the war ended. They were, quite literally, decimated.
