My family is Iranian. They've lived in Iran for over 2,000 years, which was way before the Arab/Islamic invasion of that country. So I think I can contribute something here. While Reza Shah Pahlavi was allied with Nazi Germany, he never ever turned over any of Iran's Jews to the Nazis. In fact, he like his son, Mohammed Reza Pahlavi pushed for religious tolerance towards Jews and other minorities. My parents and relatives have always said that things improved for the Jews with Reza Shah and Mohammed Reza Pahlavi. Now I don't know if these two Shahs personally loved Jews. But they seemed to respect them, and wanted to modernize Iran.
Maybe, the hatred of Jews was not part of their agenda or mindset, but a sense of racial superiority and eugenism was indeed part of it, which is what Hitler promoted through his Aryan (Pure) theology. Lisa, I can respect your perspective as a Persian Jew, but I also may advise you to be cautious. The Aryan Shah dynasty alone I do not feel is a great threat to Israel. However, it is the racial superior mindset of Persians that worries me. I have talked with enough of them to know how proud and bold they are in the defense of their race. It is the combination of their mindset of racial and spiritual superiority combined with the fact that many of them adhere to radical Shia Islam, which rules the country, is what makes me feel they are the greatest foe the Jewish people can have. Since Aryanism promotes the power and purity of the Persian people and Shia promotes the eradication of Jews, Christians and Sunnis, I feel that these two theologies combined make for a very dangerous entity, beyond that of any other.
Shia Islam has united Iran, because its militant power gives the Persians confidence against its enemies. Even though Jews were not hated to any depth in the past, today the average Persian has a deep instilled hatred of Jews thanks to the brainwashing of its Shia government. The Shia mentality is for the eradication of their enemies. Considering, the connection Persians have had to the Nazis, including the renaming of "Iran" out of respect for Hitler, it would not be hard pressed to think they would find it a noble cause to destroy the nation of Israel.
