This sounds incredibly stupid. There is no way that any city could prepare to host so many people in such a short time.
I also don't expect the World Cup to go at all smoothly. Game is in the US will not be well attended because people would have to be stupid to brave the government harassment and illegal actions. I live about 200 km north of the US border, and I haven't been there for about 6 years. I'm not sure I will ever go again.
