I think this gunman stunt was used as a distraction from the lull in the Iranian events. I expect more "loud" events when Trump will be busy tweeting on Truth Social and give speeches on telly and whatnot, looking busy and important.
This Iranian situation froze. Not much military action, they blockade, no talks. I believe two things can happen:
1. they move on, quietly focusing the attention to other issues
2. they actually preparing for invasion and they need distractions for the public.

I want to point to this book >>54223 again.
While I like to talk about the client empire part, their main point (as I noted at couple of places) that the US foreign policy works the way it works because they use policy tools as compact packages they can reach up and take from the shelves.
They have diplomatic actions, economic, overt and covert military tools. They pick one they apply it, then finish up either with a success or a failure then reach to another tool.
So on this basis how I see it they used the bombing policy from the hostile intervention toolset. It failed. It is completed. Now they are blockading which is just a form of routinely hostile activities (Isolation/Containment) they default on against an enemy state.
From here they can pick another policy tool. They could just go on with the Containment. They perhaps tried the Persuasion option, but the Trump admin's diplomatic finesses is nil, so can't really tell if they really did this or not, they could use it, but Obama did that and they hate Obama. They could do bombing again which proved to be futile, even resulted in a setback since Iran took over the control of Hormuz, and pounded the Gulf States. They could pick the Invasion option (hostile overt military intervention), or any other but the others aren't really feasible (such as financing guerillas in Baluchistan, or using punctuated military operations with the Kurds).

What they aren't doing is escalation. They escalate within one tool (eg ramp up the volume of bombing or the number of committed troops during an invasion, etc.), but not escalating from one tool to another. They use a tool then stop then pick another from the shelf and apply it.

What I can tell that the Trump admin. consisting of a bunch of retards who think they know better than their predecessors. Turns out they never learnt anything.
