Maybe we should just silently let China, South Korea, etc., be a counterweight in Pacific Asia to Japan and just tweak things to keep the simmering pot from boiling over.
The U.S., too, is a Pacific power and if we add our two cents openly, it will definitely rankle some other nationalistic egos. We should diplomatically assume a friendly as possible posture with all these Pacific Asian countries, as they are sure to become, if not already are, rich and powerful.
As long as they stay trading partners, each interdependently invested and interwoven into the others, then it should go a long way towards keeping them from trading shots.
Besides, they all may be of inestimable value in stemming the Muslim threat, especially China, who is slient on it, but does suffer more often than we do, about as much as Russia, I'd venture, from Muslim unrest.
