Absolutely! Especially given that they now have these so-called hypersonic missile that can reach United States in less than 45 minutes.  Secondly, US Military is a little tired and perhaps stretched out a little too thin.  We also owe China a lot of money, and in case of the war, we might have the capital necessary to finance a prolong non-nuclear war.  Additionally, Chinese have their citizens everywhere, several millions in the US that will be sympathetic &  may support their motherland, but how many do we have in China?
