The United States has not acquired sovereign territory since 1917, when it purchased the Virgin Islands from Denmark for $25 million. On January 17, President Trump announced 10% tariffs on eight European nations starting February 1, escalating to 25% by June 1 unless a deal is reached for Greenland.
Leaders of Denmark, Finland, France, Germany, the Netherlands, Norway, Sweden, and the United Kingdom issued a joint statement warning the tariffs risk a 'dangerous downward spiral.' About 10,000 Danes and 5,000 Greenlanders (nearly 10% of Greenland's population) protested in the streets.
On January 19, Trump wrote to Norwegian Prime Minister Jonas Gahr Støre that he no longer felt an 'obligation to think purely of Peace.' He cited the Norwegian Nobel Committee's decision not to award him the Peace Prize and linked the snub to his Greenland demands.
Denmark is a founding NATO member. Prime Minister Mette Frederiksen declared 'Europe will not be blackmailed,' and the European Council scheduled an extraordinary meeting to coordinate a response. French President Emmanuel Macron requested activation of the EU's Anti-Coercion Instrument (the bloc's 'trade bazooka,' never previously used), with officials warning of potential €107.71 billion in counter-tariffs.
A bipartisan delegation of 11 lawmakers traveled to Copenhagen on January 16-17 and explicitly opposed Trump's demands. Republican Senator Thom Tillis called coercive action to seize allied territory 'beyond stupid.' Senators Tim Kaine (D-VA) and Rand Paul (R-KY) are exploring war powers resolutions and challenges to Trump's tariff authority.
Russia called the situation 'extraordinary from the standpoint of international law.' The U.S. and Denmark agreed to form a working group. Danish Foreign Minister Lars Løkke Rasmussen confirmed Trump maintains 'this wish of conquering Greenland.'

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
February-March 2014
Russia's Annexation of Crimea (2014)
Russian special forces occupied Ukraine's Crimean peninsula in February 2014. A disputed referendum followed in March, with Russian-organized authorities claiming 97% support for joining Russia. Moscow formally annexed the territory on March 18.
Then
The G8 suspended Russia, the West imposed sanctions, and the UN General Assembly voted 100-11 to reject the annexation. Most nations refused to recognize Russia's territorial claim.
Now
The annexation preceded Russia's full-scale invasion of Ukraine in 2022. Analysts argue weak Western response in 2014 emboldened Putin's later aggression, ultimately killing hundreds of thousands.
Why this matters now
Trump's explicit refusal to rule out military force against Greenland—a NATO ally—evokes comparisons to Russian annexation logic. European leaders warn that U.S. violation of Danish sovereignty would have 'unprecedented' consequences for the international order that the U.S. itself built.

March 1917
U.S. Purchase of the Virgin Islands (1917)
The United States purchased the Danish West Indies (St. Thomas, St. John, St. Croix) from Denmark for $25 million in gold—the equivalent of roughly $600 million today. The U.S. sought the islands to protect the Panama Canal during World War I.
Then
The islands became U.S. territory. Danish subjects received U.S. citizenship. The acquisition proceeded through treaty ratified by the Senate.
Now
This remains the last time the U.S. acquired sovereign territory through purchase. The residents had no vote in the transfer—a process now considered incompatible with self-determination principles.
Why this matters now
The Virgin Islands purchase is the direct precedent for U.S.-Danish territorial transactions—and the last time such a deal occurred. However, the 1917 transfer happened before modern international law established that peoples have the right to determine their own governance. Greenland's 57,000 residents have explicitly rejected American rule.

March-October 1867
Alaska Purchase (1867)
Secretary of State William Seward negotiated the purchase of Alaska from Russia for $7.2 million ($12 per square mile). Critics called it 'Seward's Folly.' The territory was more than twice the size of Texas.
Then
Alaska became a U.S. territory with minimal infrastructure and no clear economic value. Many Americans viewed the purchase as wasteful.
Now
Alaska became a state in 1959. Its oil reserves proved enormously valuable. The purchase is now viewed as a strategic masterstroke that extended U.S. presence to the Arctic.
Why this matters now
Trump and his advisors explicitly cite Alaska as precedent for Greenland acquisition. However, Russia sold Alaska willingly to deny it to Britain; Denmark is not a willing seller. The constitutional process required Senate treaty ratification—a path that would require 67 votes Trump does not have, given bipartisan congressional opposition.
