The leaders of the USA have a big idea. They want to buy Greenland. Greenland is a very big island. It is near the cold North.
The USA wants to keep the Arctic safe. The President thinks Greenland is important. He says it helps the USA. It helps them watch for danger.
The USA thinks about the people in Greenland. About 57,000 people live there. The USA might pay them money. But the President says the USA gets what it wants.
Greenland and Denmark do not want to sell. They say Greenland is not for sale. This is a big problem.
The USA leader will talk to Denmark's leader. The USA is thinking more about the Arctic. Big countries can make small countries worry.
