Greenland's parliament is scheduled to ratify a security agreement with the United States today that expands American military access to the strategically vital Arctic island while preserving Danish sovereignty.

The deal, signed in September at the United Nations General Assembly by President Trump, Danish Prime Minister Mette Frederiksen, and Greenlandic leaders, amends the 1951 defense treaty. It permits the U.S. to establish two new bases, modernize the existing Pituffik Space Base, and deploy elements of the Golden Dome missile defense system.

Under the terms, the United States gains permanent access, basing, and overflight rights across Greenland and its waters. The agreement bars non-NATO countries, including Russia and China, from establishing military installations or exerting major influence through sensitive investments. American officials described the pact as addressing long-standing national security concerns in the region without requiring Senate approval.

A majority of Greenlandic lawmakers indicated support during initial debates last month. Greenlandic Foreign Minister Mute Egede highlighted the importance of the step for the island's security and self-determination. Danish lawmakers will begin their review process next week, with votes expected by November 19.

The agreement follows months of negotiations prompted by Trump's earlier push for greater U.S. control over Greenland. It reaffirms that any future independence for Greenland would not alter the security arrangements. Proponents note the deal strengthens NATO's Arctic posture and deters adversarial influence without transferring territorial sovereignty.
