But the US is a foreign adversary of the EU who has ruined the EU economy in the last three years and wants to wrestle away Greenland.

Half joking, but the US performs corporate espionage in the EU and certainly takes compromising material on EU politicians whenever it can get it.

The slavish adherence from EU NPC politicians (they are mediocre and no one knows how they manage to rise) to US directives has to have some reasons. Being compromised is one of those.
