If China were to do something (invade Taiwan, for example) and we came to Taiwan's defense by declaring war on China, what would allies like Germany, Britain, India, France, etc. think about our attacking a country that they have so much invested in?
Or, what would the large corporations of America, who have billions invested in industrial enterprises in China, do in response to our warring with China?
Wouldn't we be threatening the billions of dollars that millions of Americans have in stocks in these corporations?
What would the result of those losses to 401K's, IRA's, etc. have on our economy?
Does anyone think that the Chinese haven't thought this out?
Further, do you think the free-traders will allow us to actually war with China?
Well first of all, we won't honor our treaty to defend Taiwan. Foggy Bottom itself has said that US policy agrees that there is only one China. Further, all of the examples that you provided are the other reasons we won't go to war over Taiwan.
