If Greenland is a self governing country can they simply sign a mutual defense treaty with the United States and Canada (hopefully Trudeau will be gone but he doesn’t seem to go away).
Those residents of Greenland will find themselves "encouraged" to make some decisions.
As to Denmark, its military can mount about two battalions in toto. This is going to be an interesting "NATO" issue over time, as two or more NATO nations will disagree.

“...simply sign a mutual defense treaty...”
They already have. We have things up there already.
