A fascination dating back to the 19th century

The United States’ interest in Greenland did not begin with the Trump era. On the contrary, it is part of a long-term strategy that has its roots in the 1860s. As early as 1867, Secretary of State William H. Seward—who had just negotiated the purchase of Alaska from Russia—already considered the annexation of Greenland and Iceland an idea “worthy of serious consideration.” This expansionist vision was based on the Monroe Doctrine and the idea that European powers should not have possessions in the Western Hemisphere. A report commissioned by Seward described Greenland’s “unusual healthiness and its vast natural resources, predicting that annexation would encourage Canada to “join” the United States.

Concrete attempts followed one after another over the decades. As early as 1910, the U.S. ambassador to Denmark, Maurice Francis Egan, was already discussing a proposal for acquisition, even suggesting a complex exchange involving Mindanao and Palawan in the Philippines. During World War I, in 1916, the United States secured Denmark’s recognition of its sovereignty over all of Greenland in exchange for the purchase of the Danish West Indies (which became the U.S. Virgin Islands). This diplomatic recognition marked an important first step in the U.S. strategy to establish a presence in the region. World War II marked a decisive turning point when the United States, invoking the Monroe Doctrine, occupied Greenland militarily in 1941 following Nazi Germany’s invasion of Denmark, thereby establishing a military presence that has never truly been interrupted since.

The Secret Offer of 1946 and Its Lasting Consequences

The most serious proposal prior to Trump’s dates back to December 1946, when Secretary of State James F. Byrnes officially offered Denmark $100 million in gold bullion (equivalent to approximately $1 billion today) to purchase Greenland. This offer followed an assessment by the Joint Chiefs of Staff, which identified Greenland as one of three key international locations for the establishment of U.S. bases—a matter of particular importance in the context of the emerging Cold War. The U.S. memorandum described Greenland as a territory “completely worthless to Denmark” but vital to the United States, situated on the shortest polar route between Washington and Moscow.

The Danish reaction was immediately negative. Danish Foreign Minister Gustav Rasmussen, visibly shocked by this proposal, firmly rejected the three options presented by the Americans (purchase, a 99-year lease on the bases, or full responsibility for the island’s defense). This offer remained classified until the 1970s and was not revealed to the public until much later. This episode left a lasting mark on Danish-American relations and led to the signing of the 1951 defense agreement, which allows the United States to retain its military bases in Greenland and to establish new ones if NATO deems it necessary. This agreement, which remains in force today, constitutes the legal foundation for the ongoing U.S. military presence on the island and reveals the complex nature of relations between the two countries, blending a formal alliance with underlying tensions regarding territorial sovereignty.

There is something deeply troubling about this American determination to possess Greenland. It is almost a national obsession, a strategic fixation that spans administrations and decades, from Republicans to Democrats, from the Cold War to the present day. Americans view this icy island as a sort of geopolitical Holy Grail, the missing piece of their continental defense system. And what fascinates me most is this ability to justify such greed with arguments of global security, all while applying a purely imperialist logic. This is the American paradox: a power that claims to be the leader of the free world but operates according to principles that are every bit as bad as those of the old colonial empires.
