I am completely against the US-Israeli war on Iran. That said, they are not carpet-bombing Iran. That is, they appear to be selecting individual targets rather than engaging in carpet bombing entire areas:

The choice of targets is not legally legitimate (and the entire campaign is illegal AFAICT), and sometimes they used old/invalid intel, like what happened with that girls' school that's supposedly close to an IRGC base. Still, it is mostly individual buildings or installations rather than an attempt to flatten entire areas.
