This is where you are mistaken. I don’t think Israel has any illusions it can achieve regime change in Iran through air power alone. They know the limitations of such actions without boots on the ground . So logically their main aim is to destroy much of Irans ballistic missiles capabilities that can threaten Israel, reduce Irans industrial and military capabilities , reduce their security capabilities (reasons for the bombings of security agencies/police stations etc), create divisions within the regime, and most of all isolate Iran even more from her neighbours and the world .
Okay my mistake that I intrepreted your original meaning that Israel basically wants to commit a bombing holocaust on Iran. But the point stands and I would double down even more on my original stance. Unless you occupy the country, Iran will just rebuild all those capabilities once the war ends. You're acting as if being a superpower means you have the infinite ability to just bomb. Bombs cost money, they require materials to manfacture, the manufactering itself costs money, flying repeated sorties will subject your jets to wear and tear and fatigue your pilots, and then you will be required to manufacture more jets which requires more materials. Initiating war requires some justification, which this one kind of did with the protests being the cassus belli, so even Israel just can't initiate a bombing campaign because it smells that Iran manufactered a single ballistic missile. Long story short, unless the US and Israel commit to an occupation of Iran, bombing whatever strategic assets they're doing now, will only have temporary effects.
The last point is the most crucial one actually. Ideally Israel wants Iran to remain under severe sanctions and isolation . That’s the reason they have pushed for this military intervention against Iran so they can radicalize the regime even more and make any negotiations between Iran and the US/West/Aran states impossible, thereby isolating Iran and tightening the sanctions over Iran even more, thereby weakening the country economically and industrially even more . They don’t want Iran to become a normal country open to the world and intergrated within the world’s financial and economic system like most countries. That will be failure for them if Iran can achieve that and return to growth, investments , trade with all the potential Iran has , as far as the current regime remains in place as a hostile actor under the mullah regime who wants their destruction anyway, they will do everything in their power to sabotage them and maintain Iran current isolation and sanctions. So this military actions serves that purpose since it will only radicalize the regime even more (we have already seen the new supreme leader replacement being his son who is even more radical than the dad), so any negotiations and lifting of sanctions is even more far fetched which suits Israel very well.
Okay, so in this scenario Iran becomes a new North Korea. And what did North Korea despite its isolation manage to do?
I think people should often take a step back and analyse things more rationally and level headedly than just jumping in with emotions and their own personal bias which stops them from looking at things from a wider perspective. Israel so far has played their cards right actually , we can see even in Lebanon how weak and isolated Hezbollah has become , if you follow news you would have heard that the Lebanese government has taken the unprecedented step of outlawing Hezbollah armed wing and forbidden any Iranian military forces from Lebanese territory , this are things that would have been unthinkable even just 3 years ago , this all due to how unpopular hezbollahs actions has become in Lebanon especially their decision to enter the Syrian civil war and then drag Lebanon into war with Israel over Gaza, then again recently yet again over Iran being attacked . Their actions have caused huge anger in Lebanon , many now see them as merely an Iranian group in Lebanon and not a Lebanese group who prioritizes Lebanese interests . I speak fluent French so I often follow Lebanese tv stations. This is a huge change from just a few years ago. So things have avenged a lot in the region due to Israel’s actions this past 2 years .
Saying is one thing, doing is another. The Lebanese government already ordered Hezbollah to surrender their weapons last year and yet here we are in the current situation, so what does that tell you? Despite the battering Hezbollah took in the last war, you'd expect Israel to blitzkrieg what's left of them easily and yet Hezbollah is still putting up a fight. What does that tell you?
