That alone hints that it is very hard to bring a dictatorship down with just aerial attacks - the ground component is also essential. Something tells me it is going to be the same here.
Only a land operation or a total collapse of the government, with the armed police and military joining the opposition, can topple the Iranian regime.
This has been painfully obvious since aerial bombing became possible, but we’ve had so many generals and executives obsessed with the concept that it continues to be a core doctrine, like Kissinger and Curtis LeMay, neither of for whom I have anything but deep contempt.
Both regimes were deeply racist.
Anyway, I don't think that information entered on the US decision making in any way.
Desert Storm also wasn't really fast, it led to containment operations lasting a bit over a decade in total, ending only when we decided to invade Iraq with the objective of regime change and nation building. And that one, predictably, turned into a quagmire.
