For what it's worth my opinion is this is just more of the usual posturing from both.
Iran need sanction relief
Many of our international friends need that shippin groute to get supplies.
Americas pres needs a distraction from domestic shitstorms.
This isn't the first time after all we have had this shite go down 1984, 1988, 2008, 2012, 2018 and now.
The international equivalent of pavement dancing, Iran will sieze tankers for bullshit reason, keep them a few days then realse, we and the US will increase our presence and escort ships.
While in the background the diplomats will make deals.
