I am not sure that this is the right venue for the discussion of Olympic principles and values. However, as you have named my opinions inaccurate I shall reiterate them just one more time.
Modern Olympics were created due to the efforts of Pierre de Coubertin. How it evolved since then, what was said and was done is a different story (like 1936 in Berlin). De Coubertin said: "The Olympic Games were created for the exhaltation of the individual athlete. They were created for the glorification of the individual champion".
In the very first games of 1896 there were no team events except for tennis doubles. However, those pairs were often international so that they were no country team events. In the second games they added footbal.
Yahoo and sports.ru were given as example. One should be very idealistic, to put it mildly, to believe that Olympics is not about politics. 1980 and 1984, anyone? The example of South and North Korea was pure politics. I would not go into details. I just remind about the organized group of North Korean fans of about 50 during the pairs event. They came only to support their pair and did it in a sort of an eery way. Then they left during the Zamboni break. They were not there for South Korean skaters. So much for "getting closer theories"...
...yes "obliterating the borders" may be too strong a phrase to rephrase the real words of Coubertin that Olympics were for individual athletes, not for countries and their medal counts.
