Although governments that run countries would have you believe there is such a thing as a country - this is merely a fiction that is commonly believed. There are no countries, just beliefs. There are no collectives either - that too is a belief.
There really are individuals though.
I think I can reasonably conclude from watching their perspective that he's masterful in deception.
We all know that pretty much all of us here have nothing to really add to the discussion, so we might as well have some fun.
Interesting question, but not one that my post circled about. As someone who grew up at the border between three nations/languages I can assure you that even within a 100 mile radius differing history and culture can change how a average person from that nation behaves. This is curious and one can spend a lot of time pondering about where these slight differences come from – and learn a lot about other cultures and maybe even your own on the way.
What one should – however – not do is extrapolating the character of individuals from their perceived nationality (something I never suggested would be a good idea).

Citation needed. I also believe that the idea of the nation is indeed a story we tell ourselves. But firstly stories we tell ourselves are incredibly powerful: They shape actual physical reality and individual actions, and secondly the difference in languages does shape our thinking and our actions and this also has been studied. Nation borders are often also language borders.
You are surely right there, but having played with a ton of kids from all nationalities as well (football, handball, whatever) this episode still stood out for me, because it was much more brutal than anything else I had experienced out of tournaments and "serious" games. The game in question here was not even a hotel tournament, it was just a "hey, wanna play a round"-kind of game.
However: as you rightly mentioned it is unwise to extrapolate from this one experience onto the character of a group of people (I added this in the post above). This was not my intention here, it was just a very memorable experience and I never quite understood why it escalated the way it did.
