So your supposition is strategic national defense game theory should be based on hoping for a mutiny from the opposite side? Is rationality dead? What are you lot talking about.
No. But Denmark lacks the armored divisions, bomber wings, carrier task forces, etc. to pursue a "we've got a bigger stick" strategy. And undermining your opponent's will to fight was routine back when the Old Testament was written.
> Is rationality dead?
By a couple accounts I've heard, desperate senior US officers used the pre-February situation with Iran to lure Trump's attention away from Denmark/Greenland.
(If you want rational behavior from the current POTUS - um, yes, my deepest condolences, but...)
