While we disarm and dilude ourselves as to the future prospects of war, China sets up alliances for the future and arms at an interesting rate. The middle east sizzles as India and Pakistan contemplate nuclear exchanges even as we converse. Peace? Sorry, that's a fantasy as far as I am concerned. The disolution of borders is the United Nation's number one goal. No, it's not a good thing.
China and most of the places you mention are still behind us in terms of economic and political development. The foreign policy question is how do we promote the development of stable democratic states in Asia?
China is actually a good example of what I discussed in the last post. Ask yourself, why invade Taiwan? Or the Spratleys - this makes sense only for nationalist goals - which is the same thing happening with India and Pakistan.
Note that France and Germany haven't gone to war to again while prior to 1945 they fought almost continously over central and western Europe.
