More Assets being transferred to Middleeast
Whenever Trump is asked about Iran, he says we have very big and powerful ships heading towards Iran. But the CSG is already in place for several days, are they sending more ships? If that's the case then Iran is just waiting for them to set all of their pieces & assets in place, do complete strategy and hit at the right moment. Just like Iraq waited in both gulf wars, Iraq let all the enemy forces settle down and come in place and then it was game over. There's no guarantee that talks and everything else is just time buying techniques.
What Iran can/should do:
Iran wants to avoid war and de-escalate the situation. But you cannot de-escalate or avoid war when your enemy want to see you dead. You simply can't.
Now best Iran can do is to disrupt the deployments and enemy and not let them in a position to strike. Don't let the enemy organize into strike ready position.
Doing a pre-emptive strike / attacking the CSG with everything that Iran got is not an option as it will result in severe response from US, destroying all Iranian infrastructure. So what is the option here? I think the option is as long as there is no american causality that means there is still a way for de-escalation and still a way out for off-ramp. So what Iran can do is fire warning shots away from CSG. Means firing its cheap / old stock of missiles or even shahed drones at some kilometers offset of the CSG. Even if directed at CSG, they will intercept everything but you don't want to look like hitting them. You are doing this as a warning shots. The CSG will likely not take any risk and the destroyers will fire their SM-2 missiles to knock down those incoming vectors. The carrier will also as a precautionary measure will have to fly all of its aircrafts. This is a hectic exercise which bleeds energy and resources of the the CSG. Good thing is missiles fired by destroyers cannot be refilled at sea. So if Iran manages to empty the silos of destroyers then the carrier will have to go further away as it needs protection. Also how about when aircrafts land back, you fire another volley, so they have to fly again. This tiring process will not let settle CSG down. There will be no american casuality yet they will lose resources (air defense missiles) and above all the disruption caused. They will not into position to accurately do what they are planning to do. Problem with Iraq, Iran is that they never create even any disruptions while enemy is surrounding them and placing all their pieces & assets in attacking strategy. The important thing is that Iran must convey before its "warning shots" that our strikes are meant to cause no american casuality, but if US carry out strikes then our next strikes will be targeted. Warfare is not only at technology level but also at psychological level. You need to make them believe that you are ready to inflict severe costs on US no matter what. Remember, if you let americans settle properly and let them do the first major strikes then those strikes will ensure that Iran could not respond back at the CSG. Meaning they will target your missiles directed towards persian gulf & arabian sea.
So I think Iran should start disruption activities and don't play in the rules set by the enemy but make the rules of the game themselves. Its extremely important at this stage.
