A new antisemitic dog whistle I'm seeing online is when someone doesn't want to use the word "Jews" but they want to refer to all Jews, they swap in "Israelite" as in "The Israelites ____" (where the blank is an accusation of blood libel, controlling the media, banking, or some other such nonsense).
Israelites are the tribe of Israel- ie Jews. it's the same as talking about the "Hebrews", but it *sounds* like they're talking about Israelis, with a little plausible deniability thrown in.
It is *not* a synonym for Israelis, and those that use this term know it.
