the narrative that I found at France 24 was
'the tariffs that the Trump team say are not what it really is'.
so they claim that in fact they don't have as high a tariff as the Trump team determined and that thus the tariffs are unfair.
I believe the Trump team so I agree with your sentiment. But if it's proven that they Trump team miscalculated . . . then I'm sure that Trump will be magnanimous and modifying the rates.
