Iranians are not Arabs. Arabs, along with Jews, are Semites. Iranians are Indo-European genetically and linguistically.
The question earlier was why the middle east doesn't consider Israel a nuclear threat? And, that would have been referring to Arab countries. So again, since Israel fought Arab armies in 1948, 1957, 1967 and 1973 with only conventional weapons, the Arab countries seem to understand that Israel is not bent on nuclear annihilation, but only survival.
I thought Iran was Persia. Where did the word Iran come from?
Iranians genetics, or linguistic, backgrounds are non-sequitors. Only political beliefs count. They are not allies, held our embassy hostage, threatened countries for reasons of ideology, and are closer to our Cold War enemy than we are. It's not a marriage made in Heaven.
