I accept that you want to link it to recent events but it does seem that anti semitism has never gone away.Talking about the recent rise, not anti-semitism itself. It'd be tough to blame the Holocaust on conflict happening now ;)
From a 'tactical' point of view these attacks are an own goal by the pro Palestine supporters. i.e Israel can say 'Just where can Jews be safe in the world except in their own country with Jewish control'?
