Law is irrelevant under the power of the gun; it was the threat to invade Greenland and the threat to leave NATO which have triggered this.

(people keep saying things like "only Congress has the power to declare war"; that may be technically true, but a war declaration is a piece of paper, and practically the authorization of force is at the personal disposition of the President)

Not everything makes US news but the decision by Microsoft to shut down ICC accounts after a Trump EO on sanctions really spooked a lot of EU governments.

There were general and abstract privacy threats. The current US administration however has managed to alienate the EU population as well as EU politicians.

Trump has basically ended the alliance between the western world and the US and everybody has started to built around that fact. Just one example is that the EU has finalized multiple huge trade contracts, some were in the making for decades.

I don't think the next US administration - if the US remains a democracy - will be able to fix that. The US lately has been very vocal that they don't want to be the center of the western world anymore and the western world got the message.

Reorganizing the post-WWII world order will take some time, of course, but I feel like the world is proceeding quite fast.
