Nationalism is much heavier in the PRC than in the states, you can see it whenever they put on a military parade that you need a special invite to see in person. It has been intertwined with face in china for around 20 years now, or at least ever since the 2008 Olympics.
Just try living in China for a few years and tell me that mainland Chinese aren’t more nationalistic than the USA. Wolf warriors aren’t just a movie meme these days, Nationalism is full on promoted and basically required by the state not everyone is just paying it lip service.
You're back to arguing whether China or the US should receive the nationalistic medal. The discussion should be on why both are so nationalistic in the first place and how to get out of that.
