Talk of annexation has Greenland in the news again. But due to quirks of cartography, some common maps show the territory much larger than it is.

The United States operated a number of bases in Greenland during the Cold War, which an expert said it could reopen.

President Trump has said repeatedly that he wants the United States to control Greenland, refusing to take military action off the table and declaring that he will make the semi-autonomous Danish territory part of the U.

Denmark does not want to sell its territory. But for a real estate mogul turned president, the world’s largest island may be irresistible.

The sparsely-populated Arctic territory is mineral-rich, and the U.S.'s Pituffik Space Base on the northwest of the island is key for detecting any long-range missiles bound for the U.S. mainland. Danish and Greenlandic officials have repeatedly hit back at U.S. overtures toward the territory.

President Donald Trump reiterated on Wednesday that the U.S. needs Greenland and that Denmark ‌cannot ​be relied upon to protect the island, even as he said that "something will ‌work out" with respect to the future governance of the Danish overseas territory.

President Donald Trump and his top aides’ preferred path to the U.S. taking ownership of Greenland is incentivizing people there to vote in a referendum to align with the United States, according to two people familiar with his thinking and granted anonymity to speak candidly.
