All this focus is on Qatar and I can now see it being called off but what about Russia 2018? You could argue that the people of Russia deserve a world cup as they're a huge country and love their football, but if they bought the votes as well then that one should be called off too.
I'd even say if it's proved that Qatar or Russia cheated like this, they should be banned from the next couple of World Cups and Euro/Asia cups. The only thing is, this could just be the normal way that every major cup or cup final host is chosen so they might just be the first ones to get caught.
Although almost the entire FIFA exective is bent I haven't seen any evidence that Russia initiated any bribes. Which would be a first, i'd admit.
