I understand what you're saying but I disagree with the gist of what you're recommending.
I don't like the ploy of 'playing the game' (even if that game is rotten to the core) in order to achieve an end result.
Germany won the bid a few years back so I suppose there was a recent precedent for a good bid winning it, which will have inspired our thinking and our policy of putting up as good a fight as we could, albeit a doomed one - as we only now have discovered.
I think, aside from the decision they've made, it's as much the message that FIFA have sent out to us, and the comments and actions of their members towards us this time, that has now got us despairing of the whole charade.
