The use of the word “Fatherland” is extremely sarcastic, as it is closely associated with Nazi Germany.
So, for example, calling them the Department of Fatherland Security, would be seen as a close parallel to Germany’s Sicherheitsdienst (SD) (”Security Service”).
You don’t even know what you are talking about, besides when I grew up and went to school in Germany no one used the word Vaterland, we said Heimat, which means home
