A serious rebellion in China? The Chinese military will walk on it and stomp it too microscopic oblivion. That is why they have such a large army. The threat to China is Islam on its borders! They also will be walked upon not to emerge for another 2000 years. Warlords with nukes? Stop believing Hollywood and the stupidity issuing forth from there. Another serious threat to China is North Korea. China does not need it's border with that rouge state endangered by that rouge state. If China moves in any direction it will be towards Pyongyang, North Korea and that confrontation will light up Japan and it's homeboys. South Korea needs to get off of it's butt and have some serious negotiations with the North or be prepared to go north to stop the Chinese. That could be what unites Korea in the long run. China, for all it is, is hamstrung and knows it. China knows only to well it can't win anything by nuking itself or anyone else for that matter. Not to even mention Russia. The Commies, in general, have serious problems and are also well aware them.
