Yes.
Don't get me wrong. I'm not pretending that ships are sailing though the Strait in the same numbers as they were prior to March, but when it comes down to the root of it, it's nothing more than the fear of "secret mines" and/or "secret missiles" that is standing in the way of ships sailing through the Strait as they were doing prior to March. Iran doesn't have the capability to physically stop ships from sailing through the Strait (IOW "closing" it).
The only "closing" of the Strait, as of currently, is the USA's blockade (and that's targeted towards Iran, not anyone else).
