The charm offensive isn’t working.

Over the past 24 hours, the Greenlandic government has dropped its previous posture of being shy and vague in the face of Mr. Trump’s pushiness. Instead, it has blasted him as “aggressive” and asked Europe for backup. And the planned visit may only strengthen the bonds between Greenland — an ice-covered land three times the size of Texas — and Denmark.

Better the colonial power you know than…Donald Trump.

Even the dogsled race has reacted coolly. The organizers of the race — the Avannaata Qimussersua, Greenland’s Super Bowl of dogsled races — said on Sunday of Ms. Vance and her son, “We did not invite them,” but added that the event was open to the public and “they may attend as spectators.”

Now that’s a snub.
