Tunisia, for example is an Arab country.
"True" Jewish Arabs, i.e., Yeminis, Iraqis and the like (we can also ad Iran, which is not actually "Arab" in the linguistic sense, but surely is in the cultural one.) were kicked out of their home countries and went to Israel, and in fact there were more of them than Palestinians period back in 1950.
The Sephardim and Mizrahim hate the arabs more than the Askenazis, because of what the Arabs did to THEM personally.
