Yes and per article 5 the US would have to act as if they attacked themselves. Since this is quite silly, an attack of the US against Greenland would most probably either lead to the US having to leave NATO (I don’t know, if there is a way to expel a country from NATO) or NATO dissolving completely.
They are part of Denmark and they could think about joining the EU.
I’m not quite sure if they are as a part of Denmark protected by the EU defense clause, but NATO article 5 should work for them.
isnt the US also a part of NATO? and a big contributor at that?

I don’t think they plan on following the rules for this one though. Dissolving NATO aligns with Trumps interests so I can see that happening.
Although they would probably find a diplomatic way of taking control of their minerals, similar to what they just did in Panama.
