Were the Israeli fans chanting anti Palestinian songs as were reported? If so then no sympathy. If not no sympathy and prison for those attacking them. 100% Israel should be banned/sanctioned from all sports and other entertainment, business etc. to get normal Israeli people to challenge their government on barbaric war crime behavior. Likewise Russia, Hungary, China, , North Korea and Iran, Iraq, Lebanon if they continue to attack/invade kill women and children in Israel. I would look at sanctioning India, Pakistan, Sri LAnka from cricket as they continue their silly pettiness with each other and neighbours. Sport is immensely powerful and puts government under huge pressure if they are banned or people/players/iorganisations make a point. Same with UAE/Qatar/Saudi Arabia for views on women and LGBTQ rights. Shame Western politicians, FIFA, UEFA, IOC, R&A and ICC wont even try and challenge this stuff. Would work very quickly as Amnesty International and Children's Charities have pointed out numerous times.
Mexico especially and maybe Canada will be nervous about Trump's antics too with World Cup on horizon in 18months..... but I bet Trump doesn't even know or care they are hosting.
