I mean, there’s obviously something going on. Public sentiment towards Ukraine is still strong and you still see yellow and blue flags flying but sympathy for Israel was never as strong and it’s since massively died off given how they’ve reacted. The vote is clearly not a reflection of genuine public opinion. But what’s going on, are certain people just voting loads of times?
It’s not really “European” exactly; it’s a competition for member nations of the European Broadcast Union, and eligibility criteria for joining that is to be in the “European Broadcasting Area”; which, long story short, includes the whole Mediterranean area.
Is Australia in the European Broadcasting Area?
No, they’re a weird special case who have been invited for no obvious reason other than that it makes for a good Eurovision (which, to be fair, is a decent reason).
Everyone else who participates meets the normal criteria though (Israel included).
