In fact, if the World Cup is held in three countries at the same time, football fans will enjoy the weather of three countries. This will be of great benefit to the travel enthusiasts. However, we football fans hope that the next World Cup will be more magnificent than the Qatar World Cup.
The US is so huge that they have vastly different weather in the same country. New York would have snow and someone in California would be at the beach. Completely different experiences.
Canada and Mexico are even more extreme, but I don't think they are really needed to experience a difference in weather with a huge country like the US.
