Rubio’s Arctic Push: How a New Greenland Deal and an Iceland Visit Are Shaping the Contest With China and Russia

.

A Deal Signed at the United Nations

On September 23, President Donald Trump, Danish Prime Minister Mette Frederiksen and Greenland's Prime Minister Jens-Frederik Nielsen signed a new defense agreement on the sidelines of the UN General Assembly in New York. It updates a pact from 1951 that has governed the American military presence on the island for 75 years.

The text allows the US to establish new defense areas at Narsarsuaq in the south and Mestersvig on the east coast. It also lets Washington expand operations at Pituffik Space Base, its only active base in Greenland. No territory changes hands, and the details of the new sites must still be agreed by all three parties.

Greenland's leader called it an agreement "with us," not just about Greenland. Denmark stressed that its territorial integrity and Greenland's right to self-determination are respected.

Why the Arctic Matters

As Arctic ice melts, new shipping routes are opening. Whoever has influence over them gains leverage over trade, resources and military reach. The Trump administration has argued that US control over Greenland's security is needed to keep Russia and China from gaining a foothold there.

According to a US official quoted by Reuters, the agreement gives America permanent access, basing and overflight rights. It would continue to apply even if Greenland one day becomes independent. The deal also confirms that an independent Greenland would stay in NATO.

From Annexation Talk to a Negotiated Result

The agreement follows more than a year of tension. Trump had repeatedly floated buying or taking control of Greenland, which alarmed Denmark and other European governments. The final deal contains no transfer of ownership.

Asked whether US ownership was now off the table, Trump did not answer directly. Supporters see a pragmatic outcome that delivers security gains through consent rather than force. Critics note that the 1951 treaty already gave the US very broad military rights.

Rubio Takes the Message to Reykjavik

From October 5 to 8, Rubio toured Iceland, Greece and Portugal. In Reykjavik he called Iceland a "critical outpost" for monitoring hidden activity and deterring adversaries. The meeting took place at Höfði House, where Ronald Reagan and Mikhail Gorbachev met in 1986.

Rubio said the US would do nothing in Iceland without Icelandic consent. Iceland has had no military since gaining independence in 1944. The US closed its Keflavik base in 2006, and Washington is now looking at closer defense cooperation.

The visit was not entirely smooth. Iceland had recently summoned the US ambassador over a social media image it considered highly inappropriate. About 1,500 people also protested outside parliament, partly over the war in Iran. After talks with Iceland's prime minister and foreign minister, AP reported that tensions appeared to ease.

The Panama Precedent

The Arctic push follows a similar fight in Central America. In late January, Panama's Supreme Court ruled that the concession held by a Hong Kong-based CK Hutchison subsidiary to run the ports at both ends of the Panama Canal was unconstitutional. The ruling followed an audit by Panama's comptroller that alleged irregularities in a 2021 contract extension.

The company says its concession won through a transparent international bidding process. It has started international arbitration. Beijing's Hong Kong and Macau Affairs Office called the ruling "absurd" and warned Panama of "heavy prices." Reuters and AP reported that the US had made limiting Chinese influence over the canal a priority.

Outlook

The Greenland agreement still needs its technical details worked out, and Iceland has made clear that any expansion of the US presence depends on its approval. Whether these steps add up to a lasting advantage will depend on how well Washington keeps its allies on board. With Russia and China both eyeing the High North, the contest over Arctic routes is likely to shape global security for years.
