The spirit of the world cup is that national differences are put aside. It’s egalitarianism on a global scale, so yes I guess we are all communists or whatever for the duration.
Historically, I believe football (soccer) was the original game played in the US. However, Harvard didn’t like the rules, so adapted rules from Rugby, to create what has become a hybrid game. They just didn’t change the name. So much money invested in US football is probably what has kept top athletes out of soccer.
I missed most of the Brazil vs CI game. US to face Algeria.
