This begs the question... If all their family was in Israel and they longed to get back to their family... then what the heck made them move to Iran in the first place?
I’m a little slow here.. so take it easy on me...
they didnt move to Iran. I would guess the entire family once lived in Iran and a few of them got out when they could. I would venture to guess that the rest of the jewish community would love to get out of Iran, but cant because of fear of getting caught, or fear of retribution to their family.
I would assume this is similar to the cubans who would like to come here, but cant.
It is also possible that the grandparents migrated first, due to threats to the elder, and the rest of the family came after the children were old enough to travel.
