I have feeling that Trump will hit pickaxe mountain and declare victory, and after that will push towards a deal with give some and take some, for his own audience he will say that we have destroy the Iranian last nuclear facility, hence Iran will no longer get nukes. Blockade will be lifted, maybe some sanction relief, and some bases will get abandoned from ME, Iran will sell this to its people as their victory and will start the tiring process of rebuilding their economy/military bases/naval bases etc.
