I was reading ''Arab states of the Persian Gulf'' on wikipedia and this was not included, how come? and why is iraq included? Isn't it part gulf arabs, part levantines, part kurdish etc so very mixed races and some of the smaller countries (bahrain, kuwait) with iranian mix etc? ara levantines semites or is that just the gulf arabs if so then why do jews from israel are considered semites when they are levantine race?
So this isn't really a History question, but a geographic question. The Persian Gulf is the gulf between the Arabian Peninsula and mainland Asia, specifically Iran (Persia). Yemen is on the other side of the Peninsula, bordering the Red Sea and the Indian Ocean so isn't a Gulf State.
Iraq is included because it has a coast on the Persian Gulf, and is a majority Arab state.
I'm not entirely sure what your definitions are for race or for Arab, but I'll meet you on an ethnolinguistic level. Levantine Arabic is a distinct dialect from Mesopotamian Arabic and from Gulf Arabic, but they're all very much Arabic. Arabic is a Semitic language, as is Hebrew, so one could describe them all as Semites.
The nature of anti-Semitism though means that that definition would be misleading in most contexts outside language.
