I respect your work, but do think your take is highly naive. Trump has been announcing tarriffs for 30 years, so this is his ideology and it can only not happen if someone stops him.

Moreover, given the disruption and chaos which he has already caused, have shaken the confidence of economic actors across the world in the US and its adminstration. Which will have an effect on business confidence, investment plans and growth. So a lot of damage has already been done, irrespective of any potential deal to come.

I do not think there is a strategy or master plan, this is just plain economic illiteracy.
