The US, Denmark and Greenland are in agreement, and the leaders have signed the agreement that, in Mette Frederiksen's words, "could last forever."
"The United States has defended the free world since World War II and the United States has always been our friend who kept its word and whom we can trust," said the Danish prime minister during the signing.
"Mr. President, thank you. The agreement is good for the United States, good for Denmark, and good for Greenland."
Since news of the deal broke on Friday, details have been vague. But Trump confirmed in his speech to the UN General Assembly that the US will build two military bases in Greenland.
"We will have permanent control over security (in Greenland) and will do what is necessary," he said in the speech.
"No one who opposes the United States will be allowed to establish a military presence in Greenland or invest there without our express permission."
Both Frederiksen and Greenland's Prime Minister Jens-Frederik Nielsen linked the agreement to the defence agreement signed in 1951.
"This is a milestone in our long relationship. It's bigger and better (than the last one)," Frederiksen said.
"The agreement should end all speculation about where Greenland's loyalties lie. We want to continue to be a friend of the United States and part of the Western alliance," Nielsen said, ending with the Greenlandic word for "thank you."
