Building joint ventures so to say in order to submit applications to host the World Cup will also take place more often because if there is one "union" consisting of three countries applying for a World Cup and all other applicants are standalone applications, there is of course also a bigger lobby behind that union (unless it is the USA alone). But the approach to giving the tournament to several countries at once is probably more popular among society than just giving it to one country every four years. In terms of equality and also integration globally between countries this approach can only help. But infrastructure is the most basic issue here as bigger World Cups need more infrastructure. Still the USA could have done it alone, but perhaps Mexico would have had problems alone and therefore they plan beforehand to get smaller, less equipped nations under the roof of the bigger ones in a timely manner.
As you said, as long as the tournament is enjoyable and going well, I am also all or it. But I expect a great World Cup 2026. Not many reasons speak against it.
I think Canada probably pulled their weight on this one and USA carried Mexico due to football country. USA has been getting better and better at football, they have been providing some challenge to teams at world cup as well, just as we have seen them on the last one as well. But we need to realize that they are not there yet, they are still amateurs at this level and they need some improvement.
But, if you look at the home court advantage, we are going to see them do a lot different things when it is home court and that's why I believe that it shouldn't be all that shocking. I know that it would not be suddenly different and it depends on the drawing, but if they draw teams that are a bit easier and if they have the home court advantage, then I can see them going as far as semi finals, not impossible when you think about it.
