I think I can explain that: The Iranians have a strong sense of nationalism and ethnic pride that balances out and mitigates some of the Islamist influence. Cyrus, one of their great historical figures, freed the Jews and allowed them to return to Israel, and ordered the Tempe of Jerusalem rebuilt. So the Jews and Persians have a common hero in Cyrus.
That is true afterall God doesn’t change (and maybe He is remembering his promise “Those who bless YOU (Israel)..I (God) will bless..”) to the Iranian people.
