Israelis are very coward generally. If Iran sustains the onslaught for a few months, they will will leave Occupied Palestine permanently. There is a difference between people who are loyal to their land and those who have arrived to fulfill a false prophecy that they also find hard to believe. Most of them are dual nationals and don't want to give up the other nationality because they have a fear that one day they might have to go back due to millions of Muslims surrounding.
On the other hand, you do carpet bombing on Iran or Pakistan or India or anywhere else, the majority of the people won't leave. In fact they will join the forces willingly and fight till the last breath.
