The Holocaust, although not named at the time, represented a level of cruelty that was part of the Nazi ideology, which aimed to crush perceived threats and expand German territory.

The lessons from World War II highlight the dangers of allowing individuals to wield unchecked power, leading to catastrophic decisions and consequences.

Hitler's propaganda emphasizes a black-and-white worldview, portraying Jews and communists as existential threats while promoting a sense of national superiority among Germans.
