The truth is, I didn't know that now they are Considering holding the World Cups in that way with the union of these three countries, now, how are 3 countries starting in this next World Cup that happen to have several different things, in terms of culture and even in the way After entering their countries, we will see how they Manage it, of course, I am sure that each Country will help one and the other so that everything looks good, and there are no problems, because where 1 country fails, they are given the responsibility of 50- 50 for the other two that remain,but that would look very bad, and I would not agree, because a World Cup Means many good things.
I don't believe this is a problem.
The three countries have the technical capacity and competence necessary to comply with all FIFA requirements in order to have the stadiums and other infrastructure ready long before the games start.
About strategic "alignment", I believe that USA, Mexico and Canada have plenty, not only to host a world cup but also for any other political issues that involve them.
I'm not sure, but if your concern is the visa... as far as I'm aware, people only need to acquire a visa for the USA (which is more "complicated") and automatically they have a "free pass" to watch the games on the Mexico and Canada.
