Greenland, USA? How Would That Even Work?

America might be in the market for some new real estate. At the end of last week, President Trump confirmed reports that the administration is considering acquiring Greenland. Yes, that Greenland.

Mette Frederiksen, the prime minister of Denmark — of which Greenland is an autonomous territory — told Danish broadcaster DR that "Greenland will not be sold. The time where you buy and sell other countries and populations is over."

But Trump's director of the National Economic Council, Larry Kudlow, told Fox News they're looking into it.

So, how would something like that work? Is it even possible in 2019 to buy the worlds largest island, coming in at 840,000 square miles?
