Last paragraph sums it up for those looking for a quick snack:

“The claim that a trade war with the US is best avoided is valid. But Trump has already started the war. The real question then is whether Europe should surrender without a fight, hoping for the unlikely benevolence of the victor (and validating its disdain for a weak and divided EU), or whether it should fight back, while remaining open to negotiation, in order to truly seek a solution to the trade war. Bending the knee to the tyrant will most likely encourage the tyrant to ask for more. Therefore, if the aim is to end an economically devastating conflict as quickly as possible, the EU must risk responding in kind to US tariff aggression.”
