This world cup is going to be very interesting and unique because for the first time were going to have much more national teams in the world cup and on the other hand we are going to have three countries hosting the world cup at the same time.
However, the main host of the world cup is America, and the other two countries, Canada and Mexico are just helping America to host this tournament.
United States will be hosting about 80% of the matches so this argument of three countries hosting the world cup is not entirely true. And regarding the number of teams, it was long due. With the current format, the UEFA teams are over-represented in the FIFA World Cup. During the 1990s, it was justifiable, because back then the Asian and African teams were unable to compete against the UEFA teams. But now the situation has changed completely. AFC and CAF teams are giving good fight to the UEFA and CONMEBOL teams and this was very evident during the 2022 FIFA World Cup.
