'“We are seeing more and more of the fuel ships start to go through. The Iranian ships have been getting out already, and we’ve let that happen to supply the rest of the world. We’ve seen Indian ships go out now ... we believe some Chinese ships have gone out,” [Bessent] told CNBC in an interview.'

Essentially the US has admitted defeat, then. If Iran decides who gets through and who doesn't, and only allows non-US allied ships through, why is the US fine with that? Wow.
