So at the end of the day, I hope you know a little bit about World War II that maybe you didn't before you started watching this, including the Allied powers and the Axis powers, the major cause of World War II, a little bit about Hitler, we didn't go into the Holocaust, but that would be another humongous aspect of this, the extermination of six million Jews, not to mention gypsies and homosexuals and the handicapped inside that Holocaust. One of the effects of World War II would be now the Jews have no homeland, they have nowhere to go, and wandering Jews all over Europe, so we're going to get the creation of the State of Israel. We're going to get the United Nations, which is going to be like the League of Nations Part II, and now the United States is going to be not only a part of that, but really kind of the foundational head of the United Nations. We're going to get alliance systems like NATO, the Warsaw Pact, we're going to end up with OPEC, all kinds of things. I could just go on forever, but I better stop. So late 1930s to 1945, World War II, consequences are huge. If you don't know it, you're in big trouble.
