That point of view still exists in the Republican Party, but it has been eclipsed by something sadder and smaller-minded. Liberal progressives have long used national greatness as a lever on patriotic conservatives, telling them, look, our "national greatness" comes from our embrace of education, cultural change, new people, new ideas. If conservatives love our supposed national greatness, they should embrace the progressive liberal ideals that built it. Now, it's like the Republican Party has been taken over by conservatives who... decided the liberals were right? It's like they gave up and said, y'all are right, national greatness requires education, continual learning and self-criticism, openness to new ideas and new people, and acceptance of creative destruction, both economic and cultural. They accepted that, grieved, faced the choice with clear eyes, and decided that national greatness isn't worth the cost. They look at Russia and see a country that is marinating in its own chauvinism, and they want that instead.
