The World Cup is underway and Chicago is not part of it. Why not?

Former mayor Rahm Emanuel rejected FIFA’s proposal to play games in Chicago.
Chicago was a host city during the last men’s World Cup played in the US, which came back in 1994.
It seemed like an ideal place to host games, not only because of that history, but also due to the fact it boasts an iconic stadium in Soldier Field.
However, Mayor Emanuel rejected FIFA’s proposal for two reasons. One because he did not feel like his city was getting a fair deal, and the other because there was a chance the sport’s governing body could put a roof on Soldier Field.
It sounds like Emanuel thinks he was protecting the city. However, it is a missed opportunity for the nation’s third largest city which is a global city, has a busy airport that can handle all the visitors, great sites and neighborhoods, and plenty of soccer fans. And it has happened before: Soldier Field has home to five games in the 1994 World Cup, including the opening game.
Could a new stadium like the Bears are seeking have made this possible? Soldier Field is smaller in comparison to other American football stadiums hosting World Cup games. A number of the host stadiums have been built more recently. Whether in Arlington Heights or Hammond, wouldn’t a new stadium have been exactly the kind of venue to help fans experience the Chicago area?
