Guess what area lies in the middle? Not a coincidence IMHO.
your talking about the philipines? if so, why dont they approach the disputed territories? until they (or any other USN vessel) do that, this is only a largely empty threat/warning/reminder (of course, you will disagree with me, but you cant disprove it). You cant carry over "carrier diplomacy" forever. That kind of thing can backfire on you someday.
