The self proclaimed Emporer, Donaldoofus Trumpsterus is at it again….
Envoys are informal appointments and unlike official diplomats, do not have to be approved by the host country.
What this appointment shows is that Trump's ambition to control Greenland remains undimmed.
As with his military and rhetorical aggression towards Venezuela, it indicates Trump is determined to gain greater control over what his recent National Security Strategy called "the Western hemisphere", a sphere of influence that he hopes will cover the whole of the Americas.
Trump tried to buy Greenland during his first presidential term. Both Denmark and the Greenlandic government rejected the 2019 proposal, saying: "Greenland is not for sale."
