I'll tell you the real reason why you (and Andy) are bitter. You wanna know? You're not gonna like this.
You think your country is so great that there is no possible reason why anyone would turn it down to play for another nation. So when this happens you scream bloody murder (Andy mostly, on this one). Well guess what, LOTS of people have witnessed that a player from their country has chosen to play for someone else. It happens every frickin day! Podolski and Klose were both born in Poland and went on to become bigger stars for Germany than any Polish player at the time. And guess what, I don't give a shit. If that's what they want, let them do it. They don't have my support if they don't choose my team, but I'm not gonna go around bashing them like some insane zealot. Acquafresca? His mom is Polish, he spends his vacations in Poland. We wanted to recruit him for our NT, he turned us down. Big deal.
So why is it so hard for you people to accept this simple fact of life? Well, it might have something to do with the "USA numbaw one" crap. As Lewis Black said "I was amazed to discover that America is the only country on earth that keeps repeating that they are the greatest country on earth".
