It's not just about Iran, it's about exposing the effectiveness of asymmetric war.

You can outgun by far your opponents, and yet they can find cheap and effective ways to make you bleed in ways you cannot sustain for long.

This was already visible in Ukraine, where minor investments on Ukrainian side (like sabotaging gas pipelines, oil refineries or production plants) can lead to magnitude of orders outsized impacts on the war economy (and economy in general) for years.

Now Iran's showing how gargantuan has to be the US' and Israeli effort to prevent a major and long lasting choke on world economy that can be threatened by few dudes with a handful of drones/divers or small boats.

That’s when you scale up the weaponry on Iran to make economics based attacks useless.

What good is a cheap drone if the operators aren’t just dead, but wiped from the Earth? Assuming the drone hasn’t been destroyed too, it sits idle. Or redeployed by American forces against the IRGC.

A glassed Iran and $50 oil is more preferred than to have $200 oil and environmentalists backed by Chinese money dictate my life.
