It details the reasons why Hitler invaded Poland. Poland was murdering ethnic Germans in the newly created Polish nation after WW1, which stole much of the territory from Prussia, where those Germans had lived for hundreds, if not thousands of years.

Great Britain had made a secret deal with Poland to instigate a war with Germany, and if a formal was broke out, Britain would ally with Poland, regardless of who was at fault for the war. This is why Britain and France declared war against Germany for invading Poland, but didn't declare war against Soviet Russia for doing the exact same thing, invade Poland, only a short time later in the same month of the same year. For example, in addition to Poland killing ethnic Germans en masse, they openly gave out their invasion plans of Germany multiple times, openly bragged that they could defeat Germany on their own multiple times, and they attacked German installations and farms, in German territory, multiple times.

The moment you figure out that the entire narrative surrounding WW2 is bullshit, the entire charade of propaganda you've been fed should fall away. If you continue to defend the "official" history of WW2, taught to you by known liars, who've lied to us about literally everything, even about other history and wars, then you're a fool deserving a fool's reward. I hope you don't, and that you give this alternative a chance.
