Israel, after the football violence that injured their citizens and put many in hospital, and the fact the Dutch police force were unable to keep the fans safe, circulated a list of known activists and the Dutch people directly involved with the violence.
This caused great upset in the Netherlands as it was seen as unwanted interference. The Dutch have never disputed that the violence against Israelis happened and that it was pre planned. The Dutch took exception to Israel providing lists of those involved in the attacks to the Dutch politicians and media.
Hence the security decision. One could argue Israel was simply trying to defend itself. No one is questioning that the violence took place and it was anti semitic.
Whilst it is unacceptable to chant such provocative things, and pull down a pro pal flag, the violence on the Israeli fan base had already been pre planned on social media. The level of violence was not necessary or warranted and many Dutch ‘locals’ ended up in prison as a result. Everyone accepts it was anti semitic.
So the answer is not to ban anyone here. The answer is to ensure there is organised police presence and intelligence in place.
Immediate arrests for incitement and disorder. Careful choreography and armed police and horses as you would see at any football match where tensions are expected.
Those planning violence rounded uo, arrested and charged ahead of the match if proven they are organising racial /religios attacks.
I suspect some of the leaders in Birmingham have concerns about their own citizens involvement, and are aware of how this could play out globally on the international stage and the damage it could do.
The best course of action should be ti address the growing anti semitism in their own communities, not slapping bans on others!
