Yes, the Arabian (Persian) Gulf is very shallow and warm, with a featureless bottom for the most part. So the sub-surface asset luxury we use in most oceans to our advantage, does not easily exist in the Gulf. They also still have 5 P-3 Orions with sub hunting MAD gear, sonobouys and torpedoes. Their maximum MEZ for the Khalij Fars, Ra'ad and Qader missiles is about 155 - 185 nautical miles - easily encompassing all of the Gulf and just to the perimeter of the Gulf of Oman.
However, their missile seekers and signal processing systems are considered weak, noisy, klugey and vulnerable to ECM.
So as not to escalate a conflict, and not needlessly endanger assets, we would have to stand off in the Arabian Sea. Let them shoot missiles as much as they desire. Missiles do not win wars. They are bragging icons for the military-uniform obsessed. Strategy, surveillance, command, control, deception, communications, logistics, NCO's and asset flexibility/training win wars. This however, would shut down the Straights for a bit. Thankfully we have our Eagle Ford Shale tertiary oil production back online after Obama shut it down. Otherwise we would be in a tactical quandary right now. This is not the same as fracking - it is conflated with fracking because it competes with Primary oil production, and those people have a lot of lobby money.
I monitored much of the combat between Iraqi and Iranian pilots during the Iran-Iraq War. The Iranian pilots are much better trained and tend to engage for a 20 mm dogfight using skill level II tactics, rather than run. Respectful. But they do not perform well as a coordinated air sortie. Each of them thinks of them self as the star in a movie, which Allah is watching - and they conduct their habits accordingly. This makes them vulnerable to a coordinated attack or a deception lure - their ontological courage, becoming their downfall.
I would think that we let them fire their load, in a fit of Allah's awesome eschatological vengeance; missiles flying everywhere, only topped by propaganda releases about glorious victory. This is what happened with Libya - CTF 67 was kicking their ass badly - even had their old Soviet Foxtrot II sub in terminal prosecution (we opted to not kill)... and all the while they are claiming glorious victory. Tease them with air and ship incursions. And then we level their ability to refine weapons grade Uranium.
The problem with missiles is - once you run out of your latest block series, and you have to dip into the stuck-in-an-armory reserve inventory... the enemy knows this by the seeker head patterns and frequencies.
The problem with Uranium-235 is that it gives its location away.
The problem with underground bunkers, is that they most often become permanent mausoleums.
