Actually, you came in because of the Brits in 1917 and 1944. The Brits alone were not capable to start a invasion in 1944 so they called you... and you came because you didn´t want the Soviets to succeed alone.
You completely miss the point that individuality matters.
Btw, in Athens, the US team was not the most successful, because in relation to the number of athletes, other teams (incl. China) were far better.
I didn't address the point at all; you were discussing it with someone else, not me. But since you brought it up I'll give you my take: Nowhere in the history of the world has both the concept and practice of individualism been more prominent than in the United States of America, and that's precisely why we're the greatest country (producing the greatest individuals) that ever was.
