Lately, the US government has placed mounting pressure on Denmark to give up its claims to Greenland. President Donald Trump even questioned Denmark’s territorial right to the world’s biggest island. But as Danish journalist Steen Jørgenssen showed, the US officially recognized Denmark’s possession of the island over a century ago in order to purchase another Danish territory: the Virgin Islands in the Caribbean. Jørgenssen, a reporter for the newspaper Jyllands-Posten, told the World’s Host Marco Werman about his investigation leading to the original treaty signed by the US and Denmark in the Scandinavian country’s National Archive.
