President Donald Trump announced on Friday that the United States has reached an agreement with the Kingdom of Denmark and Greenland, granting the U.S. "permanent control over security, and all other needs, in Greenland." Trump described the deal as addressing "all of our many U.S. concerns," ensuring that no U.S. adversary can establish a military presence or make sensitive investments in Greenland without the U.S. government’s written approval. He emphasized that the agreement would allow the U.S. to "forever have the complete ability to do what is necessary in Greenland" to secure both Greenland and the United States. The agreement is set to be signed next week during the United Nations General Assembly in New York City. Danish Prime Minister Mette Frederiksen said the agreement "strengthens our common security in the Arctic and the North Atlantic area" and noted that it recognizes Denmark’s sovereignty and Greenland’s right to self-determination. Greenland’s government leader, Jens-Frederik Nielsen, added that the deal "ensures and strengthens the security of Greenland, the Kingdom of Denmark, the United States and the Western alliance," while acknowledging Greenland’s interests and role in international cooperation. Trump claimed the agreement would allow the U.S. to "immediately begin the process of developing a large military presence in the appropriate part of Greenland" and said the deal would have "no cost" to the U.S. The U.S. already operates a military base on Greenland’s western coast, established in the 1950s. The new agreement may allow for the expansion of such bases. It also reportedly prevents non-NATO countries from setting up military bases in Greenland and restricts adversaries of the U.S. from making sensitive investments there. While the U.S. and Denmark have confirmed the agreement, many details remain unclear. Greenland, a self-governing territory of Denmark, is not being outright taken over by the U.S. However, Trump had previously suggested taking Greenland by force or annexation, which led to protests in Greenland with signs reading "Make Americans Go Away." The agreement was reached after months of tension between the U.S. and its European allies over Trump’s comments on Greenland’s potential annexation. A working group from Denmark, Greenland, and the U.S. was formed to reach this compromise. Before the agreement can be enacted, it must go through "necessary parliamentary procedures" in Denmark.
