This exercise would have had a heavy hand from the CINC, meaning the POTUS.
You can be sure that the Lassen was doing exactly what it had been ordered to do.
As I said all along, this was more about (from the US standpoint) punctuating FON to the world, but making sure they did so with full disclosure and (IMHO) making arrangements beforehand with the PRC so there would be no miscalculations.
These further details just punctuate and re-emphasize that.
I recognise that it is the fault of the present administration and not the USN as its hands are tied.
Going by the details, one can argue equally that it was simply innocent passage as it was FON. If the whole exercise was to demonstrate FON then in my view it has failed to conclusively demonstrate it. This does not project confidence to its allies regarding US actions. In my view if the administration cannot bring itself to conduct certain actions with firmness than it is better off that nothing is done as at least there is ambiguity in it.
