Yes, seems a bit of a gap between US and Iranian opinions on the state of the strait. US says "open it", while Iran has for some time claimed it is open - only subject to conditions. Then, as you mention, the Israelis talk of an end to the blockade.

I foresee a possible relaxation of conditions on the strait by Iran while keeping their hand on the lever providing substantial leverage during any actual negotiations. I also note that it seems the US are considering Iranian demands - not the other way around. Even with that, Trumps' toughest negotiations may be with the Israelis.
