Looks like Iran decided to implement a compromised solution. On one hand, they were afraid of making POTUS (or, more generally, Uncle Sam "on the whole") too angry and therefore fired missiles into the sand. On the other hand, after all those cries from their mullahs and top military, they had to shoot at the US troops in one way or another, otherwise they would look weak. And they did fire, and some missiles even hit the territory of a US base.
Let's hope that US would not escalate on the military front. No doubt that economically they are preparing a mortal coil, but that's another story.
