Acting aggresively, but in a carefully crafted way to avoid an escalated response. The message sent internally that the other side restrains themselaee not out of reason, but fear.
That actually might be it. We can't look to people in our own government / own country like we're anything other than the boss and everyone knows it, but also, we definitely don't want to pick a massive fight with another nuclear armed power and our biggest trading partner for literally no reason at all. And so, let's play this stupid fighter-plane-chicken game with them and spin it at home like we're out there telling them what's what.
IDK if I buy it. It sorta makes sense.
It's hard to square that, though, with actually fucking up the sailors on Filipino ships in a way that seems like it should demand some kind of response. Maybe the orders were to just be pushy in a non-escalational way and things got out of hand on the ground in a way that for-real wasn't intended?
