No, that’s not how it works. These sanctions etc will for sure infuriate some people, but it will mostly make people tired of their leadership, like always. These sanctions will turn people away from Putin, it will make him look bad. His war will make the people suffer. Propaganda always exists. If Russia is allowed to compete and join the rest of the world in events and stuff, it’s like telling them “Hey, all is OK, take whatever country you’d like, we don’t give a s**t”
Smart people will see it that way. Smart people try to get their information from many different sources. Smart people in Russia have ways to find information that doesn't come from their own government controlled media. Unfortunately, not all people are smart. Most people are sheep who only follows the herd.
Personally, I'm all for excluding Russia from the world championships. But that's mostly because of my own anger and for my own amusement. But if it's actually going to help more than it harms, I can't say for sure.
