This is probably going to be first unfair olympics in history of olympic games, some countries are banned, ridiculous rules, probably no public and fans, man competing in woman category, and who knows what else are we going to see...
Why are you saying this, is there any news link that there are countries banned from participating in this Olympics, I really don't know about this.
At least 15 countries, including major powers like Russia, Iran and Turkey, can only send a limited number of athletes to Tokyo due to past doping accusations.
