I don't think it's that simple to achieve though. Look at how much Yemen has done with its limited resources. Iran could inflict pain via the Strait even with more limited resources. Iran could make it hell to try to occupy due to terrain. Nukes are scary, but they are more barbaric than they are a strategic military resource. Most of their strategic power comes from MAD and deterrence. Less from actual use.
