It is my personal belief that China does not want war with the USA... for now. They know they would lose, as they are still too weak to win a total victory over us. Twenty years from now, maybe. There may be minor skirmishes, but not war. China simply has too many internal and regional problems to resolve, as well as the need to build their naval and air forces. Plus they probably know the future battles with Islam are the ones they need to focus on, and they will need us to assist.
See my tagline.
I wonder if the 4, American, battle ready carrier groups parked there near North Korea have anything to do with the way locals are behaving.
