Lol.. that is exactly what the Americans want. The British are also pissed off, after they lost the 2018 hosting rights to Russia. They will join the Americans along with the other vassals. Everything will depend up on who is going to get elected as the next president of FIFA. If the new president is not pro-American, then the United States and its vassals will boycott the 2018 world cup (I don't think that they'll qualify, but still ).
Well, the U.S. has the bye until the fourth round of The North, Central American and Caribbean qualifier so they have until next Nov. I think to decide whether to partake in the World Cup or not. Seems pretty pointless to start in the qualifier and then later decide to boycott.
