Half a century?
Must be a typo.
Probably meant half a millennium.
Indeed. It’s a mind numbing list. Many before I was born and as a child I have no recollection. Starting in 70s I recall a number of them up until today. Apart from the number of dead and the intensity Oct 7 is exactly in line with what has gone on before and Islam in general.
It goes back much further that that. I recently read an article about Jews in Israel being attacked in 1928.
