Are you sure? I declare China the Olympic champion. They have 15 more golds then America and are only 11 medals behind.
A country can't really win the Olympics. There is no effective way to keep an accurate tally on performance.
Plus as I stated before even if one could all gold medals aren't created equal. There is no way those events are as prestigious as the more traditional ones that more truly gage a country's athletic performance and physical prowess. They're not even the newer but more popular sports in the world like football and basketball. The Chinese proved they are good in events that take coordination and little else and where you can rack up many medals with a few players in slightly different events. They are good in secondary and tertiary events that the world doesn't care as much about. When you consider the fact China has a huge amount of medals in shooting, ping pong, badminton, and diving it's not that impressive. If they were tearing up track and field, swimming, weightlifting, and the major sports they might have a point with their gold medal count despite not having the overall lead. I will admit they are good at male gymnastics though you could also rightfully take away most of the female gymnastics medals where they probably cheated. Add in the fact that there are more events to win than before and the medal totals don't really match up at all with the greatest Olympics that the USA or the old USSR had.
Plus I could argue the fact out off all the Summer Olympic powers since the end of World War II that the US is the only one that has reached it's success without unethical tactics, like a national government itself coming in and taking children from just past infancy (or at least when they are still young) to groom them specifically for competing in it. Almost everybody here is doing it because they like it and choose to do it. (A few are doing it for money but even they started out in their field because they liked their sport.) The most that happened like that in the US is a overbearing parent or two. That's not even counting the fact some of the powers have forced fed into their culture, to the point of borderline brainwashing, about how they had to be good at the Olympics. Plus the US is really the only major power since that time that has never had to engage in government sponsored cheating like the USSR, China, or most of the Soviet block countries, especially East Germany have at one time or another. Sure there have been US athletes that have doped before, but it's usually a small group of independent people that have did it, and even then most people here condemned it. It's not like the US government dumped huge amounts of resources into having whole elite groups of scientist and doctors chemically enhancing their athletes. If we had done those things with our relatively high population, income, and genetically diverse population we would have not only dominated the last hundred years we would have obliterated everybody else.
