Certainly politicians must respond to their base. However, they must also respond to American interests. GM and Boeing could be very persuasive. At the end of the day, a response to a country is based on how much power you have over the other country, If anger of the population drives everything, many South American countries and Middle East countries such as Iraq would have a much more anti-U.S. policies than they do now. What is more, the U.S. government has a lot of control over the messages from the mainstream media. No country will enter into a trade-war where the damage to one self is much greater than damage to the other side, whatever anger the population has.I'm not too knowledgeable about this but I have a feeling anti-China sentiment will be so strong after this crisis that lawmakers will have no choice but to ban any private companies from interacting with China. They won't care about the economic hit it will cause themselves as long as China suffers more. Do you think this is a possibility?
