Hell, we were the first team in our group to qualify for the WC, ahead of Mexico, T&T, and Costa Rica.
The last time I checked the USA was just behind Mexico (6th and 5th, respectively if I recall correctly). The US 'should' have actually leapfrogged Mexico in the FIFA rankings because of that last world cup qualification win against Mexico.
It's probably as PJ as described - there's some rotten politics involved.
Best just to ignore it, hope you don't get drawn in Brazil's group and prove your ability on the field of play.
Although, to be honest, I don't think the USA has the strength and versatility to win. But then I did say Mexico would beat the USA, so....
Oh, and congratulations on Australia's qualification, Stealthy.
