Israel's bombardment of Gaza provoked a big increase in antisemitism in Britain and France.

I almost never experienced antisemitism while growing up in the US. Horror over Nazi genocide made antisemitism something to shun a person for, which suppressed it to a low level.

Israel's crime in Gaza does not justify bigotry or hatred against Jews. These are two different issues. Indeed, many US Jews (and people of Jewish ethnic background, such as me) condemned the bombardment of Gaza and campaign against Israel's occupation of Palestine.

Israel itself has done its best to link the two issues, through decades of falsely claiming that those who condemn Israel's occupation policies are "antisemitic". The link can't help running both ways, thus contributing to the resurgence of real antisemitism.
