Well, it's undeniable that the sport, and the understanding of it, is growing with every World Cup. The US has the most competitive sports market in the world (and the most competitive TV market, too), so it's not surprising that soccer's growth in the US will take some time.
20 years ago, people didn't believe the sport would ever become big in Japan, with their love for sumo, boxing or wrestling. Nowadays, it's breaking all kinds of TV records, and japanese players are playing in the Champions League.
Anyway, I agree that the whole political component is unnecessary and tiresome. If you enjoy the sport, or the event, watch it. If you don't, watch something else.
