Even if it doesn't cause them to "surrender" - I still don't know what the point of this whole "limited operation" is - it would effectively set back Iran's ability to operate a nuclear materials enrichment program, among other things.
I'd also like to point out that German raids on Britain, American raids on Vietnam, and Russian raids on Ukraine are not exactly comparable to the sort of bombing raids carried out by the Allies (particularly the US and UK) in Germany and Japan in scale.
If anything, the Iranians are trying the same strategy the Nazis did with the V1 and V2 with their drones and missiles: use them as a weapon of stochastic terror against the population of the region and on the occasional industrial target.
Again, as I replied above, Japan was nuked. There were 2 bombs. That is not "sustained bombing". Also, they were losing the conventional war and US troops had set foot on Japanese soil.
The Germans surrendered because millions of Russian troops invaded their capital city. The bombing had nothing to do with it (and I would argue, even hardened their resolve against surrendering).
