First of all, don't say Iranians. Say regime supporters. Everybody in Iran, even ordinary citizens with no knowledge of military stuff, knew that this day would come and it would happen exactly like this.
Secondly, don't worry. If things remain the same, the regime will fall soon and it will be replaced with a pro-US regime. Iran will become a regional power again, but strongly allied with Israel and the US against Muslims.
You have to understand that anti-Israeli/anti-US propaganda is the regime's last pillar. If it falls, the regime won't last even a year. The regime is hated in Iran, if they tell their supporters that we have been defeated by Israel, it's over for them.
