Many is an unquantified quantity. Jew-hatred is more accurate than anti-Semitism in this context. Our supposedly peaceful coexistence with Arabs is greatly overrated, and those that believe that the Jewish state was an European Jewish invasion are studiously ignoring the millions of Yemenite, Moroccan, Iraqi, Iranian, Tunisian, etc., Jews who migrated to Israel both before and after 1948.
I don’t have an “actual” no. for “many” in the context of my previous post to you. But, I wouldn’t disagree that, overall, “Jew-hatred” is probably an accurate term than anti-Semitism; particularly in Europe.
Also, personally, I don’t know about those non-Iranians you mention. I don’t have actual #s for those Jews who have immigrated to Israel from Iran since 1948, either. But, those who did immigrate to Israel did so, I presume, because Israel, primarily, allowed “Jews” to immigrate to Israel - Not Iranians (as in nationality)? To my knowledge that is still the case.
Also, I personally know at least 10 different Jewish-Iranian families, since my childhood in Iran. 3 of them actually were our neighbours in Iran. All 10 families now live in the US. No Iranian-Jew I went to school with in Iran back in the 1970s spoke Hebrew - they spoke Farsi (Persian). Their parents, the ones my family knew & still know, considered themselves Jewish, but Iranian - not Israeli. That’s not to debate Israel as a nation state.
Anyway, the above is only giving you my experience with Iranian-Jews. Of course, most Iranian-Jews since the Mullahs’ regime (1979) have chosen to leave Iran. Just as many Zoroastrian, Moslem & Christian & Baha’i Iranians have done, for obvious reasons.
