The government of Greenland says thanks, but no thanks. 

In response to reports that President Donald Trump has taken an interest in buying the island for the U.S., the Danish territory issued a short statement today to clarify it wasn't on the market.  

While Greenland has made it's position clear...  the story raises questions as to whether such a transaction is even feasible.
