Unless you're German, than that statement is almost certainly false. And even Germany is changing.
Your statement most likely reveals more about your political leanings then the levels of nationalistic fervour in different countries.
What? Imagine a Scandinavian or a Briton chanting their countries names in any other place than a sporting event (with an opposing country). It just doesn't happen.
Other than football I can't think of any other time I've ever heard anyone chant "England, England" or whatever.
Might be slightly more likely in Scotland as they are a bit more nationalistic.
But a good demonstration of the toxic virality of nationalism, I guess. It manages to wriggle itself into anything.
I have to admit though that once on holiday in Germany, while siting in the ruins of a castle overlooking the Rhine at night, myself and some Brit and American friends of mine burst into a rousing chorus of Deutschland Uber Alles, much to the dismay of our German friends. So perhaps I have an odd sense of humor in this respect. And no I'm not some kind of proto Nazi. I also once memorized the words to much of the State Anthem of the USSR, and knew how to use them, but alas it's since largely slipped my memory. Life's too short to spend it walking around with a stick up your arse about these things IMHO.
So if you want nations not to exist, the burden is on you to come up with something better. "No nations" can look like what used to be Somalia, or what used to be Afghanistan.
I can't seem to locate the exact time, but this is most likely the interview where Elon Musk mentioned it: https://www.youtube.com/watch?v=xIDoTKMqwT4
Edit: foreign national working at SpaceX. If there were not foreign national's involved in today's success, then feel free to ignore me.
It's a commercial. What are they selling?
Bear in mind the video was a live stream. Unless the 'USA' chant was pre-planned and orchestrated by the company, it's just part of the background noise of the employees celebrating.
