Was I being facetious? Of course I was. My post was intentionally absurdist and hyperbolic. Do I expect violent riots after the host country's loss? I think it would be particularly naive to rule them out.
I would have figured that it was obvious that I'm not a fan of FIFA, the World Cup, and the allegedly magical game of fuuuuuutbol.
I can imagine after the World Cup is over, Brazil and the host city will be debt up to their ears (hundreds of millions of dollars if not billions lost because of the World Cup was hosted there). So... yes. I am aware of the political strife and economic hard times that country is/has been going through.
