the problem is even if all of the western hemisphere is one zone the US is still the best host for it in terms of existing infrastructure.
Brazil is a huge football power, but the amount of money pissed away was absurd. Was there last month. Once out of richie rich Ipanema or Copacabana, there was a lot of street art venting anger at spending billions on (now unused) stadiums rather than the poor. And whether flavellas there or some barrios here, SA poor make US poor look upper middle class.
Argentina might have some grand stadiums in BA, but those are old and it is worse off economically than Brazil now. Argentinians used to come to PY to get stuff on the cheap. Now Paraguayos shop across the river in Argieland.
If you want to rip on the US for lack of football history/culture, not sure how you can cite Canada. They made it to one. '86. (I do think a joint one might be great, if they could get some facilities up.)
As for US football culture, the article was wrong. NHL was overstated. Only reason Hockey is back in some degree of public consciousness is because traditional powers in large hockey cities Chicago, Boston ('11), and New York have had some great seasons.
Check out the massive new contract NBC took out for the Prem. Check out the ratings they are getting here... and those are stunted by the people who get up to watch matches at bars. Every Saturday bars open at 7am in the west coast and fans saunter in eating breakfast burritos and drinking beer watching matches. The sport grows and continues to grow.
I agree that England is long overdue and Australia would also be ace... but 2026 is right out for Australia seeing as the 2022 Cup, at present, is being hosted by their confederation. Even if the continental rotation was dropped, they still won't let one Federation host back to back, which is sound.
