Wonder why US doesn’t spam the strait with fake AIS signals. Do Iranians have capability to spot ships in dark at night? If they employ radar - why not geolocate radar stations? Is there other techniques Iranians have for spotting ships (EW, SAR, etc)? If Shaheds use Starlink - how come SpaceX can’t geolocate the launch sites?
