You're underestimating how much the reputation of and trust in the US has fallen in Europe. Trust arrives on foot and leaves on horseback.

It will take many good administrations to get that trust back. Especially the tariff attacks on US allies basically told us anyone can be elected at any time and throw a wrench in global trade. The amount of decoupling that's started here is huge.

These things take time to materialise so it's not obvious yet. But once the EU has alternatives for things it needs the US for (eg big cloud) why ever switch back?

Also the "buy European" movement sprung up out of nowhere and grew massively.

Trump will hopefully be a blip but the waves will be felt for years to come.

He was elected twice. We don't get to play this "it isn't us" shit now.

Trump will pass; the legacy will not. Think about the lasting effects of the Patriot Act, among many many other "temporary measures".
