There are three things you can hit to 'close' Hormuz:
- Ships
- Ports
- Oil infrastructure (like wells & storage)
Iran has already demonstrated all three. Of course, many governments in the EU, East Asia, and elsewhere are unhappy, but it's a straightforward idea. The targets are close, it weakens the Petrodollar, and might even foment unrest in the GCC against unpopular monarchs.
Saudi's MBS has been opressing the rest of the
plus the conservatives since he came to power. The UAE's MBZ is universally hated by Muslims all over the world for working with Israel & other unsavory things like the
in Sudan. Also, Bahrain's King wobbles everytime something happens and needs the Saudis to bail him out.
Mind you, that's mostly drones and missiles, Iran can also do boots on the ground. Fear of an FPV drone, IED, or a well placed shot is possibly why MBS for example has not been seen in public for some time now. The others have been seen walking around, but not MBS, the guy seems very paranoid.
So, I read the Pakistani deployment, whatever shape it takes, as a response to the paranoia that seems to govern MBS. Maybe he thinks the Iranians know he goaded Trump into it. Who knows.
