Israel's not even close to being the biggest threat for the way of living in Europe.

This is because Israel's neighbours who they are attacking aren't in Europe, and also there's a lot of tourists in Europe that Israel would like to be visiting them, but the point isn't why, it's just that Israel are not themselves a threat to Europe.

USA's probably number 2 threat after Russia. But neither Israel's nor the USA's belligerence regarding Iran seems to be so much as painting a target on European backs this time around. Which may be because Iran noticed the USA threatening Europe, IDK.
