What's even the point of the current US offensive on Iran?

I'm usually a "Sane Trump Theory" supporter, but I see no outcome where the US achieves strategic gains in this one. Even with successful leadership assassination and significant damage to Iran's current nuclear capabilities, it'll just be kicking the can down the road and galvanising even more the Iranian people against the US. There's no way an outright occupation of Iran will happen.

But most NATO substrates have also designated the IRGC as a terrorist org, which I think would imply that the offensive is somehow strategically important. I don't like the whole depoliticising "distraction from Epstein" narrative, but I'm struggling to come up with alternatives here.
