Easy answer: The US loses and loses bigly. The brutal fact of the matter is if the US needs to blockade Chinese cars lest the US automotive industry completely collapses on itself, the US has already lost. There is nothing worth protecting at that point; an industry that can't make first rate products can't create instruments of war that can win. If we wanted Pax Americana to last, shit needed to change at least a few decades ago. Anyone who was paying attention to EV development would have foreseen China dominating the field.
