China isn’t going anywhere. They can weather a thousand times the economic turmoil than us. Our gov’t has put us in this position, not the citizens. And they keep offering themselves as the cure, but it keeps getting worse. That should say something...
Historically that has not been the case. China is always trying to fly apart. It's not really one nation you know. Anymore than the Russian Empire/Soviet Union/Russian Federation is.Although perhaps they are more so now than anytime in the recent past, like the last millennium or so.
The reason Sun Tsu was such a great military philosopher was that *he had lots of observations*, mostly of Chinese fighting other Chinese.
