Vice President JD Vance on Friday during his trip to Greenland said that Denmark has not done a good job protecting the territory.

"Our message to Denmark is very simple: You have not done a good job by the people of Greenland," Vance said at the U.S. military base in Greenland. "You have underinvested in the people of Greenland and you have underinvested in the security architecture of this incredible, beautiful land mass filled with incredible people."

Greenland is an autonomous territory in the Kingdom of Denmark. 

The U.S. has a military base in Greenland, the world's largest island. But Trump has sought to annex it in an apparent effort to strengthen the United States' geopolitical position in that region of the world. 

"We have to do more," Vance said. "And what the President said in his State of the Union address, and he was very clear about this: we respect the self determination of the people of Greenland, but my argument again, to them is, I think that you'd be a lot better coming under the United States Security umbrella than you have been under Denmark's security umbrella."

Vance told Greenlanders that Russia and China, two of the world's biggest powers, also have eyes on the Arctic island as a strategic bulwark, so that should also be of concern to them.  

"This is why President Trump's policy in Greenland is what it is," Vance said. "It's consistent with the first Trump administration where you saw significant investments in Arctic security and it will continue over the next four years under President Trump's leadership."
