We could have supported the protests that happened there awhile back, and may have ended up with another Libya (you decide if that's good or not). That's a giant mess itself, but it's funny that people don't even mind a bigger mess that would be created from "bombing". lol.
I guess it'd work if you were actually commited to it (which we are not), but it doesn't help anyone in Iran, for sure. You'd end up creating even worse enemies that way probably.
