Apple, Amazon, Dell, Boeing, Nike, get hurt badly immediately. US farmers within weeks. If this fight escalates Xi, can start putting pressure to Tesla. Musk would probably throw $1B to Trump to end the pain.
Trump will cave within 1-2 weeks is my prediction. He will declare losing as winning and that will be it. Tariffs will return to more manageable levels.
The Chinese look to the future. America, barely looks past the next stock market report. Trump looks to some unidentified time in the past when daddy loved him.
Not having a high level, shared vision of the future dooms America, and the current political divide has the boat swaying worryingly side to side.
Real people are going to end up hurt because someone(s) can't manage themself.
