I would argue that the cause of World War II is World War I. So at the end of World War I, let's see how you guys are with vocabulary here. There's a treaty that ends the war. It's called the Treaty of Versailles. And when I taught this, and I don't teach global guys, I'll be honest with you, but I taught it a long time ago, I used to put a chair on the ground and then I would kick the nonsense out of the chair like, arrr, arrr. And as I kicked it I would mention some of the attributes of the Treaty of Versailles, including taking land away from Germany, the Sudetenland, making them claim it was their fault for the war in the first place, really making them pay for the war debt, all kinds of things that totally ruined Germany, created economic depression, and really made life miserable for its citizens. Not to mention an arrow through the heart of their nationalism, they really felt like Germany was disgraced.
