US to establish three new military bases in southern Greenland
The United States announced plans to immediately launch a process to develop increased military presence on Greenland. Multiple media sources report that the US intends to open three new military bases in southern Greenland, in addition to the existing Pituffik base in northern Greenland. Pituffik is a critical component of US antimissile defense systems, located approximately 1,200 kilometers north of the Arctic Circle, and hosts advanced detection and alert systems designed to identify potential missile launches against the United States.
Denmark affirms Greenland sovereignty in security agreement
Danish Prime Minister Mette Frederiksen stated that the security agreement recognizes the sovereignty and territorial integrity of the Kingdom of Denmark and the Greenlandic people's right to self-determination. Denmark characterized the agreement as beneficial for NATO and Europe, emphasizing that it strengthens security in the Arctic and North Atlantic regions while maintaining the autonomous territory's existing status.
Security agreement scheduled for signing at UN General Assembly
The Greenland security agreement is scheduled to be formally signed the following week in New York during the UN General Assembly. The agreement requires parliamentary validation from both Denmark and Greenland before it can fully enter into force, according to Danish government officials.
US secures permanent security control over Greenland
US President Donald Trump announced on September 18, 2026, that the United States has obtained permanent security control over Greenland, a Danish autonomous territory in the Arctic. According to Trump's announcement on Truth Social, the agreement grants the US permanent control over security and all other needs of Greenland without time limitations. The agreement prevents any adversary of Washington, specifically targeting China and Russia, from establishing military bases, deploying troops, or making sensitive investments on the island without explicit US authorization. The clause remains in effect even if Greenland becomes completely independent in the future.
Greenland government supports security agreement
Greenlandic Prime Minister Jens-Frederik Nielsen expressed support for the security agreement, stating that it guarantees Greenland's security and recognizes Greenlandic interests. Nielsen characterized the agreement as beneficial for all parties involved.
Greenland holds strategic Arctic location with rare earth deposits
Greenland is located at a strategically important position on the shortest route between Russia and the United States. The territory contains unexploited deposits of rare earth minerals. As polar ice melts due to climate change, Greenland is expected to play an essential role in emerging Arctic maritime routes.
1951 US-Denmark defense agreement provided prior military rights
A 1951 bilateral defense agreement between the United States and Denmark, updated in 2004, already granted the US military extensive rights on Greenland. Under this previous agreement, the US could construct and operate military installations in defined zones for island defense, provided authorities were notified. At its peak, the US maintained up to 17 military installations on Greenland. The 2004 update designated Pituffik as the sole active US defense zone while preserving Washington's ability to establish new military zones with agreement from all three parties.
Greenland agreement targets China and Russia military presence
The security agreement explicitly targets China and Russia as adversaries. US State Department officials specified that the agreement guarantees that China and Russia cannot establish military bases on Greenland, cannot deploy troops to the island, and that mechanisms are in place to prevent sensitive sector investments without US authorization. This addresses longstanding US concerns about great power competition in the strategically located Arctic region.
