I have been in London (Not Gateshead) and I remember seeing armed guards at the head of the Shuls in Golders Green.
I know others who have been to shuls elsewhere in Europe (Like Sweden) and if you want to attend services (even for Shabbat) you must register in advance as there are guards keeping people out.
To say Europe is safer to practice judaism than Israel is untrue, Ive been to bother and its ALOT safer being a jew in israel than WESTERM Europe (I’ve never been to Eastern Europe)
