Adolf Hitler's strategic decisions have often been criticized, and even ridiculed, as tactical mistakes or even acts of insanity. But most of this criticism is unsound. Hitler had a far-seeing and clear-eyed picture of world-politics. He understood Germany's place in history and what realistic options it had to secure its future--and the future of Europe. With this in mind, we can fairly assess many of his most controversial decisions.
Gregory Conte and Warren Balogh discuss the Third Reich's foreign policy and the book Hitler: A Global Biography by Brendan Simms.
