It is critically important to remember the past.
In 2002, we conducted war games against a Middle Eastern opponent generally recognized to be Iran. This was referred to as the Millennium Challenge.
Since the wargame allowed for a ship-to-shore landing of ground troops at some (unknown) point during the 14 day exercise, and because the naval force was substantial, the force was positioned on the shore-side of the region's active shipping lanes to keep them from impacting commerce during the exercise. This placed them in close proximity to the Red shore rather than at a "standoff" distance. Conducting the wargames during peacetime also meant that there were a large number of friendly/unaligned ships and aircraft in the zone, restricting the use of automated defense systems and more cautious Rules of Engagement. Red's tactics took full advantage of these factors, and to great effect.
And what did Red do? Exactly what the Iranians would.
Red, commanded by retired Marine Corps Lieutenant General Paul K. Van Riper, adopted an asymmetric strategy, in particular, using old methods to evade Blue's sophisticated electronic surveillance network. Van Riper used motorcycle messengers to transmit orders to front-line troops and World-War-II-style light signals to launch airplanes without radio communications.
Red received an ultimatum from Blue, essentially a surrender document, demanding a response within 24 hours. Thus warned of Blue's approach, Red used a fleet of small boats to determine the position of Blue's fleet by the second day of the exercise. In a preemptive strike, Red launched a massive salvo of cruise missiles that overwhelmed the Blue forces' electronic sensors and destroyed sixteen warships. The losses were as follows: one aircraft carrier, ten cruisers and five of six amphibious ships. An equivalent success in a real conflict would have resulted in the deaths of over 20,000 service personnel. Soon after the cruise missile offensive, another significant portion of Blue's navy was "sunk" by an armada of small Red boats, which carried out both conventional and suicide attacks that capitalized on Blue's inability to detect them as well as expected.
War with Iran would not be the “shock and awe” experience we imposed on the hapless Iraqis, who were a military paper tiger barely able to keep their own regime in place. There is no good outcome from escalation.
