Why would the US go to war with China? What would we gain from it? The US would like real access to the Chinese market, but war isn't a good way to do that, because the Chinese population would refuse to buy anything from US companies. Additionally, the first thing that would happen in a war is that China would stop manufacturing things for US companies, which would massively disrupt the companies, probably cause a stock market crash (for whatever that's worth) because of lowered future profit, and create a shortage of consumer goods. We actually benefit from the way things are now, we get cheap consumer goods, and we get sort-of access to the Chinese market.
