The Iranian strategy is to simply implode and explode the economies of the allies of the USA into an inflation bomb and then cause a global recession, even a depression if they get lucky. Thought that was obvious to all ?? That recession will eventually feed into the USA itself given how interconnected western economies are. Oil price shock is coming soon, given how countries are eating into their strategic reserves to try and pretend all is ok for now.
Iran does not care if the global economy goes into a recession, or depression given how disconnected they are from the global economy( side effect of the sanctions that Iran is under).
Iran's strategy is to impose a real cost on the USA so that future presidents don't do this again. Yes, Israel does not care about the economy given all that cheap oil Azerbaijan gives it via the good services of Türkiye .. Israel lives off the free USA cheque book and also in a consequence free world so that is not really an indicator of anything, and Donald Trump is too stupid to realize what is coming his way right now.
The current scenario is not sustainable for the USA, I am not sure why you think that is the case ? The USA needs the straits open and flowing again, that is why it is desperately trying to move ships across, but the volume is so small and insignificant, that it is not really worth talking about right now. The "ongoing" operations are because fundamentally Trump refuses to accept that he has lost the war, and he will as a gambler, roll the dice again after the world cup again.
Once that inflation bomb hits and the global economy starts going red, then the real negotiations will start and the USA will have to negotiate in "good faith".
