Fun fact: there is no such place as Greenland.
The Inuit who live there have always
called it Kalaalit Nunaat (The People's Land).
Around 985 Eric the Red misnamed it Greenland.
Most Europeans & their descendants continued to call it by the false name for centuries.
However, most countries have recognized Kalaalit Nunaat by its real name since it gained autonomy in 1979. So let Donald Trump buy "Greenland," then see his reaction as he learns that he spent a lot of money & gained nothing.
