I suppose the alternative would be to allow the fans in but warn them that as soon as they start chanting “death to all Arabs” or tearing down any Palestinian flags etc, that they would be arrested before any trouble could start.
They would then be sent packing back to Israel, where they can shout their unpleasant messages to their hearts content.
The trouble with that is that it wouldn't be much of a punishment and the damage would already have been done, possibly to local infrastructure. Ideally, fans who caused trouble would be arrested and charged in the UK, but that would mean keeping them in custody and all the expenses.
In 2023, Legia Warsaw was fined 100,000 Euros by UEFA for the violence at an away match against Aston Villa. Aston Villa is still seeking compensation for damage caused to the ground.
West Midlands Police don't feel they have the resources to control the match (before and after), if it turns out like the match against Ajax. If the government is so keen for Maccabi fans to be there, it needs to provide extra resources, but I have no idea who would pay.
In order to prevent German fans from Eintracht Frankfurt travelling to Naples, the Schengen Agreement has even been suspended. So people will be checked at the borders between Germany and Italy.
