There are some rules that can be derived from reading these discussions.
1. Existing tariffs=good. New tariffs=bad. No one discusses why this is. There are many, many tariffs in place. How did world trade survive in their presence. Why are the new ones bad.
2. Tariffs on things I don't buy=non issue. Tariffs on things I buy=end of the world. Apparently people on this forum are economically disconnected from everyone else.
3. My country is the injured party. Played by everyone.
4. My country's rational, measured and targeted response will result in exactly what I want. As demonstrated by each countries exact conformance to the predicted response.

I really don't think the members of this forum are going to do better than the world leaders who actually have access to the controls of this machine. Unfortunately the evidence is that we would do no worse.
