Other countries have come a long way in catching up to the US in some American-born sports like basketball, but they have not surpassed America. The All-Star team in the NBA has more international players than ever, but they are still far from a majority, and they can't beat our Olympic team even with the international NBA stars mostly playing for other countries.
But in an international sport that has been going on for a long time in other places (or at least the skills needed to train for it), the US has no such advantage.
