The President of the United States talked about buying Greenland. This made many countries talk. He said the US might buy the big land. Greenland is part of Denmark.
He said Greenland is important for safety. It is good for defense. The island has good things too. This is not the first time he said this.
Greenland and Denmark said no. The leader of Greenland said it is a dream. He wants these talks to stop. Denmark's leader also said no.
This shows countries have different ideas. Greenland and Denmark are friends with the US. They let US soldiers be there. These new ideas make things hard. Countries must decide for themselves.
