- A nation is a group of people that agree they have a common ancestral origin (note that this may be factually untrue!).
- A nation-state is a state that is dominated population-and government-wise by a nation (~75% of people in Germany are of the German nation).
- The US fails both prongs: Americans don’t agree on their common ancestral origins, and the US is not dominated by a single nation.
- The US instead is built on citizenship. Americans will not fight for their “nation” as defined above, but they will see bones and countries broken for their fellow citizens.
- Finally, precisely because of the nature of the US, being a US citizen means at some point someone in one’s ancestry broke with (or was broken from) their nation, if they had one.
As a naturalized citizen, that very much maps to my experience.
