It's logic. Very simple. There's a fair market value or range for Greenland, just like any place, IF it were for sale. The fair value or range depends upon several factors and is complicated, especially when u consider the skyrocketing inflation that diaper Don has in store for us.
If you think I'm supposed to know that fair value without an extraordinary amount of effort and research, you are, quite simply, an idiot of the highest degree.
There are probably some figures online but you can look that up as easily as I can so go ahead.
