The best books on the origin of World War II

First recommended to me by a renowned authority on European history, this big book is far and away the most comprehensive study of the origins of World War II that I read while preparing to write my own book. Watt not only traces the rise of Hitler and the absolutely ruthless steps he took to make himself master of Germany throughout the 1930s; Watt also shows exactly how Roosevelt maneuvered his way around American isolationists who were dead set against any American involvement in the new war. On top of that, Watt shows how Britain and every other European country outside Germany were responding to the prospect that within twenty years of a war that had taken 20 million lives and wounded 21 million more, Europe was facing the unthinkable: a second World War. 

Irresistibly clear and readable, this book explains the biggest mistake that France and Britain made before war broke out. Gripped by “ideological anti-Communism,” they simply could not bring themselves to forge an alliance with the Soviet Union against Hitler’s Germany. As a result, Hitler beat them to the punch. After he struck his own deal with Stalin and thus neutralized any Soviet threat to his belligerence, Germany and the Soviets carved up Poland between them. And even though Britain and France had pledged to defend Poland, the only thing they did for that poor, brave nation after Hitler invaded it was to declare war on Germany—and then do nothing for the next seven months of what came to be known as the “joke war.”

Absolutely gripping and sometimes heartbreaking account of the Widerstand—the German Resistance to Hitler, Before reading this book I never knew that just before the fateful signing of the Munich Agreement on October 30, 1938, fifty anti-Nazi commandoes led by Captain Freidrich Heinz were all set to take Hitler out before he ordered the invasion of Czechoslovakia. But once the agreement was signed, the coup was off, and General Franz Halder—the operational leader of the coup—was utterly demoralized. When he learned what Chamberlain and French prime minister Édouard Daladier had done at Munich, he reportedly “collapsed over his desk.” With Hitler now politically invincible, the resistance lost heart, and the assault squad was dispersed. “What are we supposed to do now?” Halder asked. “Hitler succeeds in everything!”

Here is the ultimate insider’s story of what led up to the deal that Hitler made with Stalin in late August of 1939. At 34, a dashing Harvard graduate named Charles “Chip” Bohlen had just become the senior Russian-language officer in charge of political reporting at the American Embassy. Though his chief job was to find out if the Soviets were making a deal with Hitler, Bohlen couldn’t get a word out of the Russians. So he turned to a young German diplomat named “Johnny” Herwarth who was secretly in touch with the German resistance. This book is the fascinating story of their covert communications on the eve of the “Non-Aggression Agreement” between Hitler and Stalin—the deal that led directly to their joint invasion of Poland in September.

This is surely the best book ever written—or will probably ever be written—on the magnificent bravery of Polish troops facing the overwhelming might of the German army and especially of its bombers. Starting at dawn on September 1, 1939, and uncannily anticipating what Vladimir Putin is now doing to Ukraine, Hitler’s forces indiscriminately bombed every target they could find with no mercy for civilians, including of course women and children. Unlike Volodomir Zelensky, who now embodies the heroic resistance of Ukraine, the leaders of Poland fled soon after it was attacked. But Kochanski explains how many of its soldiers fought on—as defenders of “the eagle unbowed.”
