Trump says US has ‘permanent control’ over Greenland security: What the deal actually does

In a deal announced on September 18, 2026, the United States and Denmark have agreed to grant the US permanent security access in Greenland. This follows Donald Trump's repeated calls for American control over the island territory over the past year. The US has long had broad military access to Greenland under previous agreements, including free movement and overflight rights.

The new deal solidifies these rights and adds the ability to establish bases or make sensitive investments in Greenland without approval from Denmark. However, Denmark emphasizes that Greenland's sovereignty and self-governance remain intact. The agreement is expected to be signed at the UN General Assembly next week, pending parliamentary approval.

While the full terms remain undisclosed, the deal could significantly bolster the US's military presence in the Arctic.
