Trump wants to buy Greenland. It's not for sale, but it would be really expensive if it were

Greenland's government has rejected the notion it's for sale.
There's also not a clear idea of how much Greenland is worth.
In 1946, former President Harry Truman attempted to buy Greenland for $100 million in gold, which is equivalent to roughly $1.3 today (adjusted for inflation). Any offer for Greenland would need to start at that price or above.

President Donald Trump wants to buy Greenland, the world's largest island, according to a report from The Wall Street Journal.

But if Trump truly has such an ambition, he's got significant obstacles ahead of him.

First off, Greenland which is home to about 56,000 people has plainly stated it's not for sale.

"#Greenland is rich in valuable resources such as minerals, the purest water and ice, fish stocks, seafood, renewable energy and is a new frontier for adventure tourism. We're open for business, not for sale," Greenland's Ministry of Foreign Affairs tweeted.

Similarly, Greenland's Prime Minister Kim Kielson in a statement said, "Greenland is not for sale, but Greenland is open for trade and cooperation with other countries, including the USA."

Greenland is an autonomous territory of Denmark and politicians in Copenhagen over the past day have scoffed at the idea of the US buying the island. "I hope it's a joke, because it's a terrible and grotesque thought," Martin Lidegaard, chairman of Denmark's Foreign Policy Committee, said in response to reports on Trump's alleged ambitions.

In 2019, it's also a bit of a bizarre and antiquated idea for one country to propose buying another, and reminiscent of the colonial era.

With that said, Denmark has also sold territory to the US before the US Virgin Islands in 1917 (formerly known as the Danish West Indies). And Trump would also not be the first president to attempt to acquire Greenland.

Former President Harry Truman in 1946 offered Denmark $100 million in gold, which adjusted for inflation is equivalent to roughly $1.3 billion in the present day. His offer was ultimately refused, though the US ended up making a deal with the Danish government to build a military base on Greenland in the early 1950s displacing a local indigenous population in the process. Thule Air Base remains the US military's northernmost base.

Today, Greenland is at the center of discussions on the globe's climate crisis and rests in an important geopolitical location between the North Atlantic and Arctic oceans and has vast natural resources.

It's still hard to say exactly how much Greenland might be worth there are no valuations available but looking at what the US paid for other territories might help provide an idea of what it could cost (even though it's highly unlikely such a deal will be considered).

In 1803, the US purchased the Louisiana Territory from France for $15 million , which adjusted for inflation is roughly $340 million in today's world. The Louisiana Territory was about 827,000 square miles (stretching from the Mississippi River to the Rocky Mountains), while Greenland is approximately 836,000 square miles.

But it's important to note that France was preparing for a war with Great Britain and was desperate for money at the time. It sold the territory to the US for a low price, now considered one of the greatest real estate bargains in history. In the unlikely event that Greenland or the Danish government considered selling the massive island, it's hard to believe it would offer sell so low.

In 1867, Russia sold Alaska to the US for $7.2 million or approximately $125 million in today's money. Alaska is roughly 586,000 square miles, smaller than both the Louisiana Territory and Greenland, but it's safe to say the US also got a bargain in this deal.

Greenland's GDP stood at about $2.7 billion in 2016, so even Truman's offer for it in 1946 (about $1.3 billion in today's money) was arguably pretty low.

In short, it's extremely hard to say how much Greenland would cost. An analysis from the Washington Post, for example, put the price tag somewhere between $200 million and $1.7 trillion.

Trump is set to visit Denmark for the first time as president in September, but the trip is not related to his reported desire to purchase Greenland. Given the response to this so far, however, it's conceivable the issue will come up at some point.
