Donald Trump can’t stop talking about Greenland. He spent a big chunk of his speech at the World Economic Forum in Davos talking about the island, saying he wouldn’t use force but threatening consequences if it wasn’t handed over.

Later that day, he said discussions with NATO Secretary General Mark Rutte had been fruitful, but Denmark and Greenland said only they can negotiate with the US over Greenland.

We break down why exactly Donald Trump is paying so much attention to this Arctic island and what that might mean for the rest of the world.
