That's such a hilariously bad take.

Iran sure as fuck isn't nervous

Man, the US inevitably failing to secure their poorly defined objective is very different from Iran not getting hurt. Thousands are dead. An immense amount of infrastructure has been destroyed.

Iran has not meaningfully hurt the US.

It's one thing to observe that the current US leadership huffed a bit too much of their own propaganda and forgot that allies have actually been a big reason previous stuff has gone well, and another to act like Iran is in a perfectly fine place with the current situation.
