Denmark, as Danes like to tell you, is a little country. But it used to be a much bigger country, a bit of an empire. Norway was once part of Denmark. Iceland was once part of Denmark. The southern half of Sweden and a bit of northern Germany used to be part of Denmark. What is now called the US Virgin Islands used to be part of Denmark.

And Denmark had colonies in Africa and India, which is why when you'll go into many Danish supermarkets – even online supermarkets – you'll see a section called Kolonial, or Colonial.

It features long-life products, like spices and nuts, that used to come from trading posts in the faraway Danish colonies.

Over time, through war losses and independence movements, the Danish Empire shrank…and today we're going to talk about how it might shrink further.

The US has made clear that it wants Greenland to be part of its own territory. Are they serious about this? And what do the Danes think?
