I think quadraphonics has it about right. China will never invade US or even fire bullets at US forces, except possibly by foolish actions by some local commander or minor incident when US is clearly violating Chinese territory, and that also will be a local mistake, not US policy. China can make "economic war" on US with considerable advantage, thanks to US "twin deficits" and when they have built up their Taiwan invasion capacity, which probably will not be used, they may use the threat of using their economic power to the disadvantage of the US to get US to agree with the re annexation of Taiwan, in accord with the long standing US position that there is "One China." Probably the growing economic ties between Taiwan's economy and China's will make this all happen with out a shot fired. The US will do quite a lot, quietly as it can, to help China in this, if China will agree to only buy oil for current consumption and not to fill their own "strategic oil reserve." China can easily begin now to buy oil at $100/barrel and that would really hurt the US economy, which is built on big gas-guzzler driving to the shopping centers. In a non-military, economic war, China is stronger. See additional comments in the "Fuel Choices,...Pollution" thread, which perhaps I should have named "Fuel Choices,...Pollution & National Security" but that would have been too long to fit.
