That tells me they were corrupt hangers on of the Shahs with dual Israeli/ Iran citizenship in case of a revolution.
How do I know? There was a piece in Ha’aretz interviewing some Jews that live there. They are not Zionist Jews. They are peaceful Jews that just want to enjoy their lives, friends and family.
They were even embraced by the Iranian govt and citizens.
They are left alone to worship and practice their religion as they please. Even Netanyahu who offered to pay them to come to Israel was unsuccessful. They told him “we love it here. It is peaceful with no sounds of bombs everyday. ( they were referring to the Iron Dome of course, that detonates its own missles it launches to pretend to the Israeli citizens those are from Hamas.) I understand this is constant, with the sound of fake sirens, fake roadblocks and fake screaming. All props, all acting.
Now you know why I call Israel cartoonishly evil?
