Let us not forget that, based on Iran's behavior the past few weeks, they don't care about the MU (they never did and never intended to to begin with anyway) but also completely disregard the fact they do not own Strait of Hormuz in its entirety.
They share it with Oman.
And the past few weeks, all of the ships attacked by Iran were those transiting in the Omani lane because they were transiting in the Omani lane, and not the Iranian one.
