Israel gets kicked out way before that. They have a population of 10million. Spain and the Netherlands are much larger then that. More viewers = more money

The only reason Russia and Belarus are banned is that basically the entire West was calling for it. That did not happen with Israel. Just looking at the Olympics, the only ones calling for Israel being banned were the Palestinians. Nobody else, not even from fellow Arab countries could get up and complain at the IOC. No wonder nothing happened. Same is unfortunately true for other countries like Myanmar, which is currently also committing a genocide. The West really does not care about that one though. Either way that is.

Russian athletes are allowed to compete as neutrals in international events, as long as they do not openly endorse the war in Ukraine.
