This is the end of Iran. They don't have the AD to stop the attack. So, they have 2 choices, see their Nuclear plants destroyed without retaliation or only symbolic retaliation. Or Go full on attack on Israel and US bases and thus starting a full scale war. I don't think Iranian population is loyal enough to withstand a full scale war. Losing nuclear plants without any meaningful retaliation is going to be so embarassing that it will embolden Israel and US to go for more attacks to bring regime change.
