Crippling tarrifs you say, a quick Google says Greenland export $36M to the US in 2022, which is basically nothing. And don’t forget the people who pay the tarrifs are the American people not the country the tarrifs apply to. Just because someone says I want to buy that, it doesn’t mean it’s for sale. The only way the US will get Greenland is by invasion and occupation. So the EU response of ignoring the giant toddler is probably the correct move.
