Ugh, your lack of understanding of such a simple issue isn't interesting at all. It's downright silly.
No, really, I'd like an answer. Klose, Podolski, Boateng, Quincy.. they're all traitors? But then again.. had they chosen the other country instead, they would have been traitors too.. right? What's more important to you, Andy, ius soli or ius sanguinis?
And what about a guy who doesn't have let's say the American nationality, but has lived there all his life. He's now 25. His parents are both Indian and he was born in India, but they moved to the States when he was 1 year old. Can he support the USA? He probably can't right? He should support.. well.. India? Although.. He's never been there.. wait.. I don't think this is simple at all.
