That's what you do with someone with whom you're having an adversarial deal.
Denmark is an ally in NATO.
Denmark is an ally in NATO that’s underpaid their fair share by an estimated 50-$100 billion (not adjusted for inflation). Meanwhile the US has paid a disproportionately high share for decades. Sure, Denmark built a wonderful social safety, but the US paid for it. Germany, Italy, Spain, they’ve all underspent their commitment for years and we’ve picked up the tab. Hundreds of billions.
These rich nations are just finally upping their spending after underspending and using the money to live high on the hog while we covered their asses, so yeah no shit Trump is going to fuck with them.
