One thing in any protracted conflict with the Chinese is that they lack ingenuity - they can copy quite well, but invention is not their forte - or quality control for that matter. Sophisticated manufacturing techniques using CNC equipment isn't very widespread in China outside of foreign corporations. Mao's Cultural Revolution resulted in a dumbed-down populace just as designed - that's one thing we can actually thank that SOB for.
I expect to see China doing everything it can in the near future to appear to be on America's side, since they must be terribly worried about our newfound alliance with Russia. Granted, their rhetoric will always be shrill, but they don't dare push any issue against us directly. They prefer to work behind the scenes in order to have others do the actual fighting - like al Queda - that way when their proxies are defeated they still have the deniability they need. Otherwise, the failure of their "employees" would reflect poorly on them. Saving face and honor (their own proprietary version) is their main goal at all times. Should the US and Russia become true partners in geopolitical affairs, the ChiComs are screwed - and they know it. All I can say to China is: Phuc Hu.
