Yeah, it's maybe the greatest difference between Patriotism and Nationalism: the former is all about "I'll work to make my house the best house" whilst the latter is about "Yield to me, as I am from the best house".
Patriots want their country to be the best country, Nationalist want to extract gains from living in what they think is the best country.
You'll notice that the only things Nationalists ever do for their country are things like "stopping others from coming here" or "celebrating the greatness of their country", which aren't at all about making the country better.
You seem to be implying all people and countries are on a scale moving closer to some single ideal.
I mean that's definitely how some people interpret it but at least for me, patriotism encompasses the idea that my country should be best for me and the people in it but that other people in other countries get to think the same thing about their country and work towards their own version of "best."
But I'm not gonna argue that everyone does patriotism this way because that's clearly not the case 🙃 plenty of "patriots" out there willing to wreck their own country in a war over bringing their own ideals to a different place.
