I agree, but iranians have a long arm, in the form of short range ballistic missiles like Fateh110/313 and their antiship versions are enough to extent the control of whole Persian Gulf. Not to mention cruise missiles that are very easy to hide and disguise. Also the hand would be OWA drones, specially the jet powered Shahed 238 (which probably was the one that hit those tankers and E3) and Sadid 110 can cross the Persian Gulf in few minutes, closing any gap.
All Iranian weapons can be protracted underground or disguised in civilian trucks or ships.
Remember those weapons doesn't need command an control centers. They don't need nuclear submarines or fighters/bombers to be launched and are by definition not needed to be guided by third agents or assets, like JDAM bombs or some cruise missiles like Delilah/JASSM (firsts versions at least) that need fighters or bombers to get closer to targets, air bases and/or carriers and therefore hundreds of personnel and auxiliary services.
Finally all of them are considerable cheaper than US/Israeli counterparts.
So if geography, orography, doctrine, tactical weapons and económic aspects are favourable to Irán... They will control entire Persian Gulf.
