Every proposal in American history for buying Greenland has been considered by President-elect Trump.

The possibility of the United States purchasing Greenland has been rekindled by the incoming Trump administration, an idea that was previously floated during the president-elect's first term in office.

Trump stated that Denmark essentially owns it, and that they are good allies with Denmark. He added that the concept of the idea came up and he agreed to it. However, he noted that it is not the top priority and they will discuss it further. Trump also stated that the media is vital to making America great again and that he will work with a free, fair, and open press.

Trump's interest in buying Twitter was initially reported by the Wall Street Journal, citing sources who said he had discussed the idea with varying degrees of seriousness. However, the plan was put on hold after Biden took office in 2021. Now, the idea has resurfaced online following Trump's recent victory.

Republican Congressman Mike Collins of Georgia posted an electoral map featuring Greenland on November 7, with the territory voting GOP. The map was captioned "Project 2029." Since then, a member of parliament in Denmark has pushed back on the idea of the United States purchasing Greenland as an American territory. According to a post from Rasmus Jarlov, the Danish parliament does not intend to offer the territory to anyone, especially the United States. Jarlov wrote, "Greenlandic independence requires approval by the Danish parliament and a change of our constitution. I can guarantee you that there is no way we would approve independence so that you could buy Greenland. Nice fantasy but forget it."

The United States has previously considered purchasing Arctic landmass for strategic benefits.

In 1946, President Harry Truman proposed $100 million to Denmark as compensation after World War II, but Denmark declined the offer.

Earlier in 1945, Senator Owen Brewster, R-Maine, considered Greenland a "military necessity" backed by American military leaders.

In 1946, a State Department official recorded that the Joint Chiefs of Staff believed the U.S. should acquire the territory. That December, Secretary of State James Byrnes directly offered to purchase the territory from Denmark's Foreign Minister Gustav Rasmussen, suggesting it would be the easiest solution.

The State Department recognized the strategic importance of Greenland and Iceland in 1867, and explored the possibility of buying both territories.

If Greenland were to be sold to the United States by Denmark, it would represent the largest territorial expansion in American history, surpassing the Louisiana Purchase of 1803.
