While everything you said may be correct (I’m not an expert), I doubt NATO countries want to get in an energetic war with the US. It’s simply so costly in lives and resources and effort.
Hypothetically if the US “takes” Greenland I fully expect all the NATO countries to declare war on them (as article 5 requires), but not attack with military.
They’ll sell all their bonds and completely shut them out as if they don’t exist. Zero trade. No tech. No services (google, apple, etc). Not a single thing in or out to/from the us.
Yes it would really suck for every country, but I suspect it would suck less than either slowly letting the US walk all over them and slowly take any country they want, or an energetic war.
The US is putting its head in the sand and going backwards on renewables and vehicles and science and tech and so many more things. They’ll become an island if this happens.
I don’t put it past trump to try. It’s exactly the kind of “emergency” he needs to give himself emergency powers and stay in office indefinitely.
