Iran bought this upon itself. There was an MOU, it was not perfect but Iranians thought they could make Hormuz their lake and overplayed their hand.
US spared many civilians targets and Iranians thought they had a victory of sirts.
Now that is about to change.
The MOU was basically let oil prices stabilize and allow more strategic supply into market before going back to war as demands US we're making to be negotiated over 60 day ceasefire were basically surrender. It's same 'deals' that Hamas in Gaza was offered.
Iran strategically made right decision to see through that and prevent stabilization of oil prices and prevent oil flooding markets to buy more time to allow for war while expending strategic supply which would have been resupplied basically.
The reality is US is seemingly taking orders from Israel to attack and demand total surrender and thus making it exisistential war for Iran. They cannot surrender unless they're willing to change path of last 40+ years entirely and join Western Camp.
This is not a good precedent that is being set by US and Israel ever since the Holocaust in Gaza. It's like they're trying to self rationalize genocide of Muslims. And I had many differences with Iranian regime btw, you can ask Iranians here how I was vocal about them too but I think in this situation they're pushed with their backs against wall and have to play Strait of Hormuz control/toll card until US drops other demands.
Israel itself cannot and isn't military capable of doing a judgement day style operation on Iran like they did in Gaza and Lebanon where they ravaged everything. They need US refueling tankers and munitions and much more. Many targets they don't have munitions to be able to cause a dent to, only US does.
So it may appear as a result of this that US is being rational and Iran isn't, but in background Israeli is goading Trump very hard to undergo a genocidal style rampage to try bringing out a surrender....
Trump let's them down everytime to buy time until a Democrat gets elected , maybe, and they Israelis maybe keep bringing up blackmail. The scary thing is if Israeis loses patience and end up assassinating Trump doing false flag operation. And even worse the Jewish deep state ends up accusing Iran or something to bring about a genocidal attack on Iran. If the Zio Cult resorts then they become an existential threat to the entire world that have to be put down even at price of Israeli nuclear attacks around world. Israel would need to be nuked many times over to set example to other nations as it would be worse than 9/11 scandal and be very bold to try something like that
