That just sounds like more 'strongly worded letters' which never go anywhere and they never do anything about. It's over for the EU. They rested on their laurels for too long and cowardice rotted them from the inside. I don't think Denmark will put even a smidge of resistance up. Trump is going to bark some orders, boots are going to hit the ground and it's fait accompli .
What does action (i.e. not-strongly-worded-letters, i.e. not words) look like? Capture Trump? Invade the US? The idea the EU is some bureaucratic hellhole incapable of anything is really odd and nigh-universal - I'm used to righties adopting it from Brexit & antipathy for social demoracy, but I'm not used to see it as a despondent wailing from people otherwise sympathetic to it.

Even now, the EU Commission is trying to 'defuse' the Greenland situation by trying to invoke NATO's fifth article, as if that's worth anything without the will of the USA behind it.
