"is advised that he MUST change course "
Perhaps that is a faulty premise? I mean, I've never had the big gray boats phone me up to discuss the time of day, much less the weather, but would a warship ADVISE ME TO CHANGE COURSE? Or, COMMAND ME to change course?
My recollection is that the warship would ADVISE me, and that means compliance is strongly suggested but in no way COMMANDED OR REQUIRED. (At least, not in your scenario, although IIRC there are currently some large "keep away" zones in effect for US ciitzens and US warships.)
You know, like the old tale of the lights seen in the storm, and the escalating conversation about which of them should change course? Where one stubborn skipper finally says they are an aircraft carrier, get out of the way, and the other one says that's all nice, but they are a LIGHTHOUSE and he really doesn't care what the carrier thinks?
