Are the underage allegations just proof of the fact the US team are sore losers?

No, I don't think they are being sore losers. The allegations were brought up before the Olympics began. Yes, the US made mistakes, but they still took the Silver! China is a communist country where they will do whatever it takes to win and look good in the public eye, especially at the Olympics! Didn't you all hear of the girls at the opening ceremonies? One was not cute enough, so they had another lip sync the song! She apparently was a cuter 9 year old!!
