I think this is the elephant in the roomt - in terms of quantifiable goals, Iran is winning this thing. I think they're going to want to punish the US and Israel to an extent where they will be reluctant to feel this particular sting again, and they want to assert their ability to control the strait. And it's working! They're clearly demonstrating that the US cannot simply decide when this is over and dictate terms, because Iran can pinch off an important vein of global commerce and probably sustain that pressure for far longer than it can be tolerated by other economies.

They've already gotten one concession in terms of this temporary sanctions relief, even as Trump frames it as a domestic emergency measure and repeatedly declares total victory each day of the conflict. They also got him to back off on targeting their power plants by promising to retaliate in kind against the power infrastructure of US aligned states in range.

I think the US has the ability to beat Iran in a fight, but it does not have the preparation or the resolve to do so at this time, because this is some halfcocked nonsense plan with amorphous goals that they thought would be over in a week.
