Well, IMO, they're just as dependent upon us. As for the loans China has given us, as J Paul Getty once said: "If you owe the bank $100 that's your problem. If you owe the bank $100 million, that's the bank's problem." Plus, they have big trade interests with the US. The US and China like to criticise each other, sometime rightfully and sometimes wrongfully, but each pretty much is dependent upon the other. If China attacks Taiwan, it will have a hell of a problem given the Taiwanese alone. Trying to invade it is one set of lumps internationally and between Taiwan, and trying to hold it if they succeed in invading it is permanent set of them. As Minister Tallyrand quipped: "You can do anything with bayonets...except sit on them." If the Taiwanese don't want Red China taking it over, all Red China will be doing is swallowing a razor blade trying to successfully conquer it.
